What Products Can Be Made from Injection Molding?

Posted on by

The process is highly versatile and can produce a myriad of parts for a wide variety of applications.

 

When creating a product that requires molded plastic parts, depending on the type of application and type of part you want to produce, you have several processes to choose from. One of the most popular processes to achieve high quality and cost effective plastic parts is injection molding.

 

Injection molding is a manufacturing process for producing parts in large volume – from thousands to millions. Melted resin is injected into a hollow mold until it is completely filled. The injection molding process uses high temperature and extreme pressure to sufficiently fill the interior with molten plastic resin or liquid polymers. The molds are then cooled to release completed plastic parts.

 

The process is highly versatile and can produce a myriad of parts for a wide variety of applications.

 

Typical Products Made with Plastic Injection Molding

Plastic Bottles are the most common product manufactured by the billions each year, ranging in multiple shapes and sizes. Typically, the plastic bottles used to hold potable water and other drinks are made from polyethylene terephthalate (PET), because the material is both strong and light.

 

Electronic Housings are also quite commonly fabricated with injection molding services. Used in devices such as remote controls, computers, televisions, medical equipment, and other consumer electronic components, housings are all produced by injection molding process. Injection molding services can manufacture any custom plastic enclosures for practically any application and sizes.

 

Toys: Imagine a building material which is lightweight, durable, and doesn’t corrode; it comes in many sizes and colors and is designed for easy precise assembly. The Lego brand of building block recognized by all is made of firmer plastic granules which are heated until liquefied and then injected into metal molds in which the plastic cools and solidifies into a studded brick or other shape. But what’s important is that each brick and component is accurately molded so they’ll all fit together. It’s a precision product available in many colors, shapes, and sizes.

 

Agricultural: OEMs designing for the agricultural marketplace are switching to plastic as a low cost alternative to metal components commonly used throughout the industry. Plastics offer higher resistance to impacts during use, humidity, and are able to resist extreme high or low temperatures. UV additives also help protect plastic parts from harsh weather conditions or exposure to corrosive substances.

 

Household: Molded closures, containers, components, and drinkware are just a few of the common items that can be custom fabricated with injection molding.

 

Machinery and Automotive Components: Bumpers, dashboards, radio controls, cup holders, and many other elements found in cars and transportation vehicles, both interior and exterior, are made by the injection molding process.

 

Healthcare Industry: In the healthcare field, there are thousands of products that are made with the injection molding process. The healthcare industry relies heavily on multipurpose plastic products that can be manufactured in bulk, as many of these products are single use, disposable items to maintain sterility or to prevent the spread of germs or disease. From plastic syringes to tools used in medical procedures, injection molding is what helps the medical professionals get their jobs done.

 

Injection Molding is a very common manufacturing method used to produce everyday household items. The applications cover commercial, industrial, and consumer products alike. Injection molding offers the versatility to generate designs that have intricate detail or complexity, down to simpler forms in any range of sizes from small to large objects.

 

This method has produced solid parts such as electronic housings, bottle caps, containers, computers, televisions components, bag accessories, outdoor furniture, agricultural products, toys, machinery components, and much more.

 

If you need plastic injection molding services, I recommend you to visit Shin Fang Plastic Industrial Co., Ltd. – they are the experienced manufacturer of specializing in various plastic injection products. Now, check out their website for more details of plastic injection moulding.

CNC Guide: Best Design Practices for Custom CNC Machining Parts

Posted on by

Here’s a good refresher on common practices to keep manufacturability and cost in mind when designing a part.

 

What exactly is computer-numerical-controlled (CNC) machining? It’s a means to make parts by removing material via high-speed, precision robotic machines that use an array of cutting tools to create the final design. CNC machines commonly used to create the geometric shapes required by customers are vertical milling machines, horizontal milling machines, and lathes.

 

To successfully make a part on a CNC machine, programs instruct the machine how it should move. The programmed instructions are encoded using computer-aided-manufacturing (CAM) software in conjunction with the computer-aided-design (CAD) model provided by the customer. The CAD model is loaded into the CAM software and tool paths are created based on the required geometry of the manufactured part. After determining the tool paths, the CAM software creates machine code (G-code) that instructs the machine on how fast it should move, how fast to turn the stock and/or tool, and the location to move in a 5-axis coordinate system.

 

Complex cylindrical shapes can be manufactured more cost-effectively using a CNC lathe versus a 3- or 5-axis CNC milling machine. With a CNC lathe, cutting tools are stationary and the part stock is turning, whereas on a CNC mill, the tool turns and the stock is fixed. To create the geometry, the CNC computer controls the rotational speed of the stock as well as the movement and feed rates of the stationary tools required to manufacture the part. If square features need to be created on a round part, the round geometry is first created on the CNC lathe and then the square features would be made on a CNC mill.

 

Because the computer controls the machine movement, the X, Y, and Z axes can all move simultaneously to produce a range of features, from simple straight lines to complex geometric shapes. Some limitations do exist in CNC machining, and not all shapes and features can be created even with the advances made in tooling and CNC controls. The limitations will be discussed later.

 

General Tolerances

If a drawing or specification sheet has not been provided by the customer, a company may provide general specifications to follow to manufacture a model. These specifications may change from one company to another. In addition, some companies do not have default tolerances and will require the customer to provide the specifications.

 

Part Tolerances

Tolerance is the acceptable range for a dimension, which is determined by the designer based on the form, fit, and function of a part. It is important to keep in mind that a tighter tolerance can result in additional cost due to increased scrap, additional fixturing, and/or special measurement tools.

 

Longer cycle times can also add to the cost if the machine needs to slow down to hold tighter tolerances. Depending on the tolerance call out and the geometry associated with it, costs can be more than double of what it would be to hold the standard tolerance. Tighter tolerances should only be used when it is necessary to meet the design criteria for the part.

 

Furthermore, overall geometric tolerances can be applied to the drawing for the part. Based on the geometric tolerance and type of tolerance applied, cost may rise due to increased inspection times.

 

The best way to apply tolerances is to only apply tight and/or geometric tolerances to critical areas, which will help minimize costs.

 

Size Limitations

 

Milling

Part size is limited to the machine’s capabilities and depth of cut required by a feature in the part. Keep in mind that a build space’s dimensions don’t equate to part size. The features and size of the part will determine the part’s machinable height.

 

Lathe

Lathe capabilities will depend on the build space, or the diameter and length. A company may also offer a live tooling lathe, which dramatically decreases lead times and increases the amount of features that can be machined by combining additional CNC milling functions within the lathe.

 

Material Selection

Material selection is critical in determining the overall functionality and cost of the part. The designer must define the design’s important material characteristics—hardness, rigidity, chemical resistance, heat treatability, and thermal stability, just to name a few.

 

Metals

As a general rule, softer metals, like aluminum and brass, as well as plastics, machine easily and will take less time to remove material, which in turn reduces time and cost. Harder materials, like stainless steel and carbon steel, must be machined with slower spindle RPMs and machine feed rates, which would increase the cycle times versus the softer materials. As a general rule, aluminum will machine about four times faster than carbon steel, and eight times faster than stainless steel.

 

Plastics

Plastic material can be a less expensive alternative to metals if the design doesn’t require the rigidity of metal. Polyethylene is easy to machine, and costs about 1/3 that of 6061 aluminum. In general terms, ABS is about 1½ times the cost of Acetal; nylon and polycarbonate are approximately three times the cost of Acetal. Keep in mind that depending on the geometry, tight tolerances can be harder to hold with plastics, and the parts could warp after machining because of the stress created when material is removed.

 

Complexity and Limitations

The more complex the part, which means contoured geometry or multiple faces that need to be cut, the more costly it is due to additional setup time and time to cut the part. When a part can be cut in two axes, the setup and machining can be accomplished faster, thus minimizing the cost.

 

For simple two-axis parts, more material will be removed as the tool moves around the part than with a contoured part. With a more complex part, some areas will need to be cut with X, Y and Z axes moving together.

 

To create a complex surface with a good surface finish, very small cuts will need to be used. This increases the time and, therefore, price of a part. A general rule to help minimize the cost is to try and design using only two axes cuts, but this isn’t always possible if a certain look or functionality is required. Keeping things consistent, such as internal corner radii and tapped holes, will also help save time and money on parts by reducing the need for tool changes.

 

Five-Axis Machining

Five-axis machining capabilities allow for more complex CNC machining parts to be manufactured in the most cost-effective manner. Five-axis machining means that the machine and the part can be moved in up to five ways simultaneously around multiple axes. The coordinated movement allows for very complex parts to be manufactured more efficiently because it minimizes setups, attains faster cutting speeds, generates more efficient tool paths, and achieves better surface finishes.

 

By using five-axis technology versus conventional three-axis machining, fewer setups are required to create a part with complex geometry. With three-axis milling, contoured parts, or parts with machining on several faces require multiple setups to create the geometry. Oftentimes, with three-axis machining, complex fixtures must be made in order to hold a part in the orientation necessary to create the feature. Five-axis machining eliminates the need, and thus cost, of creating the fixtures, because the part can be held once and rotated to create complex geometries.

 

Finally, by using a five-axis capable machine, the machine and part movement allows for the cutting tool to remain tangential to the cutting surface. Lower cycle times and costs are achieved because more material can be removed with each pass of the tool, and better surface finishes result by using the five-axis capabilities on contoured geometry. In traditional three-axis machining, very small cuts must be used to create a good surface finish, resulting in longer lead times.

Benefits of a Proximity Card Reader

Posted on by

As far as access control systems go, a card reader is still one of the most popular ways to secure a building. Keyless entry systems include proprietary proximity cards, magnetic stripe cards, biometric systems, and even smart cards. For many facility managers and business owners, the benefits of a proximity reader far outweigh the initial investment cost. These benefits include:

 

Loss Prevention

Proximity readers are a simple and convenient way of securing your entire building and individual rooms inside it. For example, you can require your employees to swipe their card to gain access to the office and again to access the lock-up closet or computer lab. This means that card readers can effectively reduce stock room shrinkage, tool bin losses, and other back door shortages.

 

Building Security

One of the most obvious benefits of an access control system is that you can identify and regular who enters your premises. Unless your business welcomes and invites walk-in customers, a proximity reader can secure your building from unwanted or unauthorized visitors. This level of security will keep your products and equipment safe, but it will also protect yourself and your employees safe from an armed robbery or violent attack.

 

Employee Tracking

Depending on the type of access control system you choose, you may be able to track individual swipes at a given location. This means that you can easily track your employees’ attendance and timeliness. You can also keep track of who swipes into valuable areas so you can easily recover missing tools or equipment.

The Use of Shredders in Recycling

Posted on by

A shredder is a machine or equipment used for shredding. Shredding systems are used to reduce the size of a given material. While most online dictionaries define the shredder as “a device used for shredding documents as a security measure to prevent identity theft,” shredders can be of many types based on the material being processed.

 

There are shredders designed to support material reduction across a range of recycling applications, including plastic recycling, e-waste recycling, scrap metal, tire recycling, and wood recycling. The shredding process produces raw material to be re-introduced into manufacturing, as well as finished products such as landscape mulch. Various terminologies are used to describe size reduction equipment, including grinders, chippers, granulators and hammer mills. Overall, their main function is to reduce the size of a given material.

 

The Consumer Shredder Versus Industrial Shredder

Based on the purpose of use, shredders can be categorized as consumer shredders and industrial shredders. Thus, a paper shredder normally falls into the category of consumer shredder as it is mostly used by consumers.

 

Industrial shredders are typically heavy-duty and high volume systems used to process such recycling material streams as e-waste, plastic, wood, and paper. Industrial shredders are equipped with different kinds of cutting systems such as vertical shaft design, horizontal shaft design, single shaft, two shaft, three shaft and four shaft cutting systems.

 

The Use of the Shredder in Waste Management

In waste management, industrial shredders for waste products play a very crucial role. The benefits of using mega-shredders in large-scale waste disposal systems recycling centers and municipal landfills are related to material reduction. Asphalt, rubber, wood, plastics and similar materials can be quickly condensed to a mere fraction of their original size. Also of note, bio-degradable waste decomposes faster when shredded. If properly shredded, the materials that are buried in landfills take much less space.

 

The Use of Shredders in Recycling

In today’s economic environment, communities and businesses are always looking for new ways of cutting costs and use of shredders provides new strategic options. There are two main purposes of shredding materials in a recycling process.

 

Firstly, by reducing the volume of material through reduction, transportation and storage costs may be decreased. Secondly, automated shredders, particularly in e-waste recycling, also liberate materials for recycling. Such equipment is offered by several vendors. Many options are available, depending upon the specific application. Before making an investment, potential buyers should understand such factors as:

 

  • Assortment of items to be recycled
  • Volume of throughput
  • Requirements of residual buyers in terms of such parameters as particle size

 

A flat incline belt is often used to feed materials into the shredder. The material can be placed on the belt through a variety of methods, depending on the particular operation. Material handling equipment assigned to perform this task can include grappling devices, front-end loaders, forklifts and drop-bottom containers.

 

Shredding solutions of choice typically involve low speed, high torque units that slowly tear material apart, minimizing problems such as embedding metal in plastic during the shredding process.

 

Where large items are to be shredded versus a stream of only smaller items, a larger primary breakdown unit may be required. A second pass can be then made with a secondary shredder or granulator to further reduce particle size and facilitate the liberation of recyclable materials. Sizing screens are utilized to ensure a uniformly sized product.

 

Some vendors offer a single pass machine that will do both the primary breakdown and particle reduction. A variety of sorting machines can be used to sort material for maximum recovery.

 

If you have requirement of plastic shredder machine, I recommend you to visit Ko Win Yang Industrial Co., Ltd. – they are the professional manufacturer of specializing in plastic recycling machinery. KOWIn continuously dedicates to the research & development and marketing of various types of plastic recycling machinery for a long period.

Using A Quality Medical Caster, A Matter of Life and Death

Posted on by

If you work in any kind of medical environment, then you’ll understand the importance of having good, reliable medical casters. Transporting medical equipment around using casters can quite literally be a matter of life and death, and you need casters that you know will never let you down.

 

Additionally, casters used in medical facilities may come into contact with hazardous materials and chemicals in particular. You’re therefore going to want to purchase casters that will not fail should they be used in places where hazardous substances are likely to be encountered.

 

You also need to keep two other key factors in mind – floor marking and quiet rolling. It is important that floors are kept clean to help prevent contamination and the possibility of trip or slip hazards. It’s also important that the casters you select for use with your medical equipment have non-floor-marking properties. You should be fine if you use casters where the wheels are manufactured from rubber, nylon, polypropylene or urethane.

 

Enjoying Go Co., Ltd. manufactures quiet, smooth rolling casters and wheels for medical needs. Their medical casters provide best mobility solutions for medical environments, such as bed tables, IV poles, computer carts and medical service carts.

Do Laser Printers Require Ink or Toner?

Posted on by

Laser printers use toner, which is a fine powder that gets melted onto the paper to create a permanent image. Toner-based printers, which also include xerographic copiers, typically print very quickly and turn out documents that last for many years without fading or smudging. They also usually have long cartridge lives, making them well suited to the heavier printing volumes that most business printers are expected to generate.

 

How Laser Printers Work

Laser printers start the printing process by having a laser beam aimed at a rotating light-sensitive drum flash the image of the page, charging the areas of the drum that correspond to where areas of black or color appear. The drum then rotates through a toner reservoir where the oppositely-charged toner jumps onto the areas that were struck with the light. The partially toner-covered drum then rotates until it reaches the heavily-charged paper causing the toner to jump off of the drum and onto the paper. The paper then passes through a fuser, which melts the toner onto it, on its way to the printer’s output tray.

 

Benefits of Toner

Toner is typically made of uniformly shaped particles, which give output with a very smooth appearance. Since it’s a solid that gets melted on to the page, toner tends to withstand both moisture and smudging better than ink. The solid nature of toner also eliminates the risk of it drying out if it goes without being used. With the exception of some small personal laser printers, laser printer toner is also usually less expensive than ink for inkjet printers.

 

Drawbacks to Toner

Toner cartridges tend to be expensive, with some costing over $200, although high-capacity toner cartridges typically last longer and offer lower costs per page than inkjets. Color laser printers that use toner also typically offer less vivid colors and a smaller color gamut than inkjet printers, making them better suited to printing color documents than photographs.

 

Other Laser Printer Consumables

Laser printers typically have a number of consumable items in addition to the toner. Some printers include the drum in the cartridge, while others have less expensive cartridges but a separate drum that also needs periodic replacement. Color laser printers typically also require fuser oil to help bind colors to the paper and toner-waste bottles that need replacement as well.

 

If you have requirement of printer cartridge or ink cartridge, I recommend you to visit Cartridge Web™ – they specialize in kinds of high-quality remanufactured toner cartridges and compatible toner cartridges.

The Aluminum Die Casting Process and The Growth of Die Casting Industry

Posted on by

The casting process implements a steel mold often capable of producing tens of thousands of castings in rapid succession. The die must be made in at least two sections to permit removal of castings. The casting cycle begins with the two die halves are clamped tightly together by the die casting press. Molten aluminum is injected into the die cavity where it solidifies quickly. These sections are mounted securely in a machine and are arranged so that one is stationary while the other is moveable. The die halves are drawn apart and the casting is ejected.

 

Die casting dies can be simple or complex, having moveable slides, cores, or other sections depending on the complexity of the casting. Most machines use mechanisms actuated by hydraulic cylinders to achieve locking. Others use direct acting hydraulic pressure. Die casting machines, large or small, very fundamentally only in the method used to inject molten metal into the die.

 

What Are The Advantages Of Aluminum Die Casting?

There are many reasons aluminum is the most commonly cast non-ferrous metal in the world. As a lightweight metal, the most popular reason for utilizing aluminum die casting is that it creates very lightweight parts without sacrificing strength. Aluminum die casting parts also have more surface finishing options and can withstand higher operating temperatures than other non-ferrous materials.

 

Aluminum die cast parts are corrosion resistant, highly conductive, have a good stiffness and strength-to-weight ratio. The aluminum die casting process is based on rapid production that allows a high volume of die casting parts to be produced very quickly and more cost-effectively than alternative casting processes. Aluminum die casting has become the favored option for buyers worldwide. Characteristics and Advantages of Aluminum Die Castings include:

 

  • Lightweight and Durable
  • Good Strength-to-Weight Ratio
  • Great Resistance to Corrosion
  • Excellent Electrical Conductivity
  • Fully Recyclable and Reusable in Production

 

Aluminum Die Casting Product Segmentation

The popularity of aluminum has expanded to many applications around the world today, driving competitive market shares primarily for its distinctive features such as lightweight; corrosion resistance, high electrical and thermal conductivity, high stability for complex shapes and high tensile strength. The transportation sector is the largest end-use segment for this industry. The increasing emission laws by the government regulatory authorities, along with consumer demand for a higher fuel-efficient vehicle is developing a necessity for aluminum casting. An example of increased operations for the industry includes the replacement of iron and steel components in a vehicle with lightweight high-quality aluminum in order to increase the fuel efficiency. The aluminum die casting product is ideal for electronic connectors and housings die to its excellent electrical performance and shielding properties, even in high-temperature environments.

 

Another sector regarding the aluminum die casting demand includes building and construction in developing economies particularly in the Asia Pacific region. Aluminum Die Casting is associated with the creation of products including windows, cladding, curtain walling, prefabricated buildings, shop partitions, and fittings. Also, aluminum die casting products are used in aerospace operations or airplanes all around the world. The aerospace industry wants to produce a denser and larger quality product at lower costs for these air-frame components as aircraft continue to grow in size along with population rates.

 

According to Transparency Market Research, the Asia Pacific region accounts for over the half the share in the global market for aluminum castings. In the years ahead, the region is expected to further increase its share by pulling in the maximum Compound Annual Growth Rate of 5.3% during the forecast period between 2017 and 2025, and the powerhouse of China taking most of the credit. This market region is expected to become US $22.67 bn by 2025. Another important driving force includes the regions of Europe and North America in the global market for aluminum castings. While Europe is expected to register a Compound Annual Growth Rate of 5.1% during the forecast period to become worth US $9.45 bn, and the North America regions is expected to rise at a Compound Annual Growth Rate of 4.9% to become worth US $4.22 bn by the end of the year 2025.

Guide of Metal Stamping Dies: How Does Metal Stamping Work?

Posted on by

Metal stamping is the practice of cutting and forming metal sheet into a required contour with the help of tool known as a stamping tool.

 

Metal stamping is the practice of cutting and forming metal sheet into a required contour with the help of tool known as a stamping tool. Sheet metal components are used universally, from the regular clips to complex computer hard drive components, all are manufactured by a precision sheet metal stamping process. Stamping die design is the preliminary phase in stamping tool and dies making and is carried out as soon as the component design is finished. The stamping die drawing stage is extremely critical as a good quality stamping die blueprint can generate accurate stamped components which can run for an extended time with less maintenance.

 

Stamping tool design calls for selecting the required metal stamping operations, basic strip layout, manufacturing processes, type of stamping presses to be used and so on. It is necessary for a tool designer to have thorough knowledge of these elements to construct a fine die design. Computer aided design techniques have progressively developed in the last decade to assist die designers.

 

There are various procedures involved in metal stamping tooling designs which are necessary for accurate tool production. The very first stage in die design is the process of evaluating the metallic part to be made, its properties, dimension and complexity of the contour. Next the designer will proceed with the strip layout design and then he will determine the cutting force and the die-set to be used and then begins making the assembly sketch. Once the assembly sketch is completed, part details, drawing of die parts, and the final step of preparation of the bill of materials can be undertaken.

 

How Does Metal Stamping Work?

Metal Stamping includes many different types of sheet-metal forming manufacturing processes. Key parts of the process include punching (using a machine or stamping press), blanking, coining, embossing, and bending. Stamping is primarily carried out on sheet metal, but can also be used on other materials, such as aluminum, steel, plastic and foil.

 

  • Bending

Process that result in a V, U, or channel shape in any bendable material (most often sheet metal) without fracturing. An example would be the bottom of drinks can.

 

  • Blanking

A shearing operation uses a punch to create a blank from the sheet metal or a plate.

 

  • Progressive Die

Metal Stamping die that pushes a sheet of metal through a series of operations until a finished part is made. An example would be the lid of a soda can (separate operations for the lid and pull tab).

 

  • Compound Die

Metal Stamping Die performs more than one operation in a single press.

 

  • Deep Draw

Process of a drawing press is used to form sheet metal through the mechanical action of a punch. An example would be a kitchen sink.

 

  • Tapping

Process of cutting is the threads in a hole. An example of this would be a nut, where a bolt screws into.

 

  • Coining

A precision metal stamping form used most often where high relief or very fine features are needed. An example would be money (quarter, nickel, dime), badges, and medals.

 

  • Embossing

Metalworking process of soft malleable metals are shaped and designed by hammering on the reverse side.

 

  • Blanking

Metal stamping operation by the sheet metal is punched to get the required outer profile of the sheet metal component. During the blanking process the blanking punch penetrates into the sheet metal and forces the material into the blanking die. The portion of the sheet Metal which comes out through the blanking die opening is the component with the required profile. Hence it is important that the dimension of the blanking die profile is equal to the dimension of the component profile. In blanking tools, the cutting clearance is given on the blanking punch.

 

If you have requirement of metal stamping dies, I recommend you to visit Coolmosa Technology Co., Ltd. – they are the professional manufacturer of specializing in metal stampings. Now, check out their website and feel free to contact with Coolmosa for more details!

There are any numbers of issues that can cause your air conditioner to stop working. Luckily, they’re not all expensive fixes. The problem could be just a loose wire that’s caused a power failure in your air conditioner. Or you could have a clogged air filter that’s impeding the air flow to the system.

 

On the other hand, when AC compressor failure causes your system to breakdown, you have a major AC emergency service problem and a big expense on your hands. The compressor is a vital and expensive component, and when it goes you may find yourself dropping a lot of cash on a new AC unit.

 

The good news is, as much as 80 percent of the causes of AC compressor failure are preventable if the problems leading to the failure are corrected in a timely manner. These problems can be detected and eliminated during regular AC preventative maintenance.

 

What Is The Compressor?

Your air conditioner’s compressor is often called the heart of the system. This is a good analogy for a few reasons:

 

  • It’s one of the key components without which the system can’t function.
  • It’s usually very reliable, and if it’s failed before its expected life span (10 to 15 years), it’s probably due to an underlying cause that’s often preventable.
  • It does fail, it’s expensive and sometimes impossible to fix it.
  • Like your heart pumps blood through your body, the compressor’s job is to compress the refrigerant gas (hence the name) and pump it through the system so that it can remove heat and humidity from the air.

 

Now that you understand why it’s so critical to keep your compressor in good shape, let’s take a look at some of the things that can cause AC compressor failure and what you can do to avoid them.

 

Problems That Cause AC Compressor Failure

When AC compressor failure happens, it’s often due to an underlying issue that causes stress on the system. That’s important to know for two reasons:

 

  • By detecting and fixing the underlying cause, you’ll prevent AC compressor failure
  • If you replace a failed compressor without fixing the underlying cause, the new compressor is likely to fail as well.

 

These are the common issues that cause AC compressor failure:

 

  1. Dirty Coils.

When dust, grime and mineral scales build up on the condenser coil, the air conditioner can’t expel enough heat from the system and it’s forced to run constantly trying to cool your space. The increased pressure and temperature can cause the compressor to overheat and fail.

 

  1. Blocked Suction Lines.

When your air conditioner’s refrigerant lines become blocked or damaged, the first thing you’ll notice is that the unit is not cooling as effectively. If the problem is not fixed, once again the increased pressure and temperature cause overheating and AC compressor failure.

 

  1. Low Refrigerant Charge.

If your system’s refrigerant lines develop holes or cracks, the air conditioner leaks refrigerant. After a while, the level becomes so low that the compressor has to work harder to pump enough refrigerant through the system to cool your space. The strain can eventually cause the compressor to break down.

 

  1. Incorrect Suction Line Size.

If your refrigerant line develops leaks and needs to be replaced, make sure you get an experienced AC technician to do the job. A line that’s too large or too small for your system can cause premature AC compressor failure.

 

  1. Too Much Refrigerant.

If a less-than-qualified person works on your air conditioner and inadvertently adds too much refrigerant, or even the wrong type of refrigerant, it can be a deadly mistake for the compressor.

 

  1. Electrical Problems.

An electrical failure can result in a buildup of acids that cause a great deal of damage to other parts in addition to the compressor. If you have a failed compressor, make sure the technician tests for the presence of these acids. If he finds them, an electrical burnout has caused damage throughout the system that is probably not worth fixing.

 

But electrical problems are often easily preventable when an experienced tech inspects your system: he can spot and repair damaged wiring, fuses and contractors before they take down your system and cause AC compressor failure.

 

  1. Contaminants in The System.

The high heat and pressure in an air conditioning system, not to mention the locations where they are typically housed in New York City (outdoors, on rooftops, in crawl spaces) can introduce any number of contaminants that can cause damage. These include air, moisture, dirt, debris, leaves, soot, acids, and even bird and pest droppings.

 

  1. Inadequate Oil Lubricant.

To take the heart comparison a step further, think of your air conditioner’s oil lubricant like the blood in your body. If there’s not enough, the system can’t work properly and all kinds of problems can result, including AC compressor failure. When your system is regularly maintained by a trained AC professional, he will check the lubricant levels and the condition of the oil pump to prevent this problem.

 

Take good care of your compressor with regular AC preventative maintenance

When you take good care of your compressor, it will take good care of the air in your space with consistent, reliable cooling. That means having your air conditioning system serviced at least twice a year by a reputable AC service company.
