Die Casting Parts Around Your Lives – Learn What Die Casting is.

Die casting is an important manufacturing technology used in many industries. Companies can make nearly all parts using different casting processes.

 

What is Die Casting?

 

According to The Engineer’s Handbook, this is a manufacturing process where solid metals are melted and heated to a desired temperature after which, it is poured into a cavity or mold with proper shape.

 

The melting and heating process may require different furnace heating temperatures. Moreover, different chemical substances may be added to modify chemical composition of metals.

 

The process may be a single step of a series steps depending on the complexity of the metal substance. Cast parts may range from fraction of inches to over 35 feet. And final product can have virtually any size depending on what designer desires.

 

Apart from these, it is also crucial to highlight the major metal casting processes that have been used in this industry.

 

  • Sand casting
  • Lost Wax casting
  • Permanent mold casting
  • Centrifugal casting

 

What Makes Die Casting a Distinct and More Importantly Intriguing?

 

All the other processes I have listed above are collectively referred to as “foundry processes” except die casting.

 

Let’s zero into what die casting is.

 

The Engineering.com defines die casting as a manufacturing process that produces metal parts of virtually all designs by forcing molten metal under high pressure into a die cavity. The underlying factor here is exerting high pressure through a die.

 

It is a key factor that distinguishes this metal fabrication process from the other metal casting procedures listed above.

 

For instance, if we look at a process such as lost wax casting, investment casting or sand casting procedures, the underlying factor in this case is the fact that, the process depends on gravity to fill the mold.

 

The Cambridge Dictionary defines gravity as a natural force that attracts objects towards one another, more so that force, which makes things fall on the ground.

 

This further reveals more properties of die casting in relation to other metal casting processes.

 

Here are three key points to note:

  1. Metal die casting process has a short cycle time
  2. Metal flow is faster in die casting due to existence of external force
  3. Molds in die casting are not as thick as those used in the sand casting or investment casting processes

 

Metal die casting process is used to produce various shapes from a number of non-ferrous metals such as brass, zinc, aluminum, magnesium and copper among other metals.

 

It is one of those manufacturing processes with the ability to produce high detailed and accurate parts. It is also preferred for mass production of components as opposed to other manufacturing processes. Take for instance, the faucet parts, door knobs, decorative parts, etc.

 

Die Casting Examples

Die casting is one kind of technology that we have lived to embrace in our day-to-day activities. This is a popular manufacturing process that is used to produce a number of metal parts both for industrial and domestic applications.

 

For this particular section, we’ll categorize these parts based on where they are used i.e. their industrial or domestic applications.

 

The most common die casting examples include the following:

 

Brass Die Casting Parts

These are common examples of die cast parts that we meet in our daily lives. They are available in different configurations. These lamp parts include brass fixture body parts, necks and breaks among others.

 

Most lighting distributors place their orders to different lighting parts suppliers, and give the brass lamp parts order to a casting manufacturer; this will save them a lot on cost.

 

Brass Parts May Include:

  • Brass electrical components such as the socket termination parts and coaxial cables.
  • Mechanical parts such as those that are used in the plumbing industry. These may include pipe joints, washers, nuts, flanges and T-joints just to mention a few.
  • House accents such as brass candle holders, vases, canisters, decorative pillows, etc.
  • Furniture hardware such as door knobs, locks, and handles.
  • Brass precision components such as clips, connectors and taps among other sections.

 

Zinc Die Casting Parts

Zinc is also a popular metal that is used in this industry. Normally, the manufacturers have to choose between the ZA and ZAMAK alloy. The choice of any alloy will depend on the desired physical properties of the end product. That is, parts cast using the ZA alloys have superior strength due to high mounts of aluminum. The Zamak alloys offer better castability.

 

The zinc die casting parts may include window hardware, electrical components, bathroom fixtures and office equipment, just to mention a few.

 

Steel Die Casting Parts

Like the other metals mentioned above, the steel cast parts also form an integral role of our lives. This involves casting different types of steels such as stainless steel.

 

Some of the most common components that are manufactured via this technique include valves, hydroelectric turbine wheels, tooling equipment and pumps among other parts in food, electrical and power industries.

 

All these parts must be manufactured as per the international standards and regulations.

 

Iron Die Casting Parts

This involves casting a number of iron carbon alloys. These metals have a carbon content that is more than 2%.

 

Again, the iron casting company should be able to choose that specific metal that can meet the requirements of the end users. This involves determining the carbon content, iron and silicon content.

 

Aluminum Die Casting Parts

Both aluminum and aluminum alloys are commonly used to cast different machine components. These alloys contain different elements such as copper, manganese, magnesium, silicon and zinc, just to mention few. These elements exist in different proportions thus; different procedures can be used to cast the aluminum parts.

 

These aluminum die casting parts are used in different industries such as aerospace, electronics, plumbing and chemical industries.

 

Summary

In summary, there are very many types of components and structured that can be manufactured through die casting. It is upon the end user to choose that kind of metal he/she desired for a given application. However, some may require additional secondary operations.

Pro and Cons of Using a Malleable Iron Pipe

While malleable iron pipe fittings may sound old-fashioned next to lightweight PVC pipe, it has become valuable once more for solar heating systems, and other applications. Learn more about the pros and cons of malleable iron pipe below.

 

Pros of Malleable Iron Pipe

 

Malleable iron pipe fitting is the conduit system of choice for solar heating systems. Most solar heating systems for interior heat and hot water supplies use a dense fluid to trap solar energy. This fluid becomes much too hot for PVC pipes to tolerate, but malleable iron pipe is ideal to transport it. All the fittings of a solar heat system can be made of malleable iron pipe. Malleable iron pipe fitting is also best for cold water plumbing, as it retains its shape in the coldest conditions. Malleable iron is used for galvanized pipe fittings and can be zinc coated for rust and corrosion prevention prior to installation in a plumbing system.

 

Cons of Malleable Iron Pipe

 

Malleable iron pipe fitting without a galvanized zinc coating is unsuitable for factories and fluid transport facilities located near ocean and lake docks. It can rust and corrode on exposure to salt and other waterborne minerals. Heavy malleable iron pipe has been replaced by PVC for household plumbing.

Permanent Makeup Vs Microblading – What’s The Difference?

When it comes to waking up with the perfect eyebrows to envy all others, there are two techniques that are used in the industry; traditional Permanent Makeup and Microblading. But what’s the difference between the two techniques and what fabulous results can each treatment offer? Read more below:

 

Permanent Makeup

Permanent makeup is the most common phrase used but terms such as Micropigmentation and permanent cosmetics are also used to describe the same procedure. For permanent eyebrows, as well as lip and eyeliner treatments, a cosmetic tattooing machine is used to gently implant pigment into the skin using a variety of fine needles. It’s different from a regular tattoo machine in that the frequency is much lower meaning the pigment is implanted closer to the surface. Some would say the sensation feels like an electric toothbrush pressed against the skin; a little uncomfortable but not too painful.

 

There are a variety of looks you can opt for when choosing your permanent makeup treatments. If it’s a dramatic powder brow you are looking for to mimic the look of makeup, you’ve got it. If it’s more realistic brows you’re looking for go for a procedure using individual strokes to create your desired brow shape, go for it. You can also opt for bright lips, natural lip blush, subtle lash enhancement or feline Latino eyeliner flicks – the choice is yours!

 

K.B Pro Brows: Microblading

Microblading is a slightly different technique that’s still firmly in the tattooing family, meaning pigment is implanted into the skin, but a precision hand tool is used instead of a machine. The beauty of microblading is that the hair-like strokes you can achieve are so fine that it’s the most hyper-realistic treatment yet, it’s no wonder that it’s often referred to as ‘eyebrow embroidery’.

 

A microblading technician meticulously draws each hair stroke onto the skin to follow the direction and length of the existing hairs. If there are no hairs present, not to worry, a skilled technician can create beautiful brows that suit your face shape and mimic that of a natural brow. The channels created by the microblading technique are closer to the surface then when using a machine and the needles used are even sharper, meaning even more precise and finer hair strokes can be created. If you want the most natural looking treatment that no one could ever guess you’ve had, this is ‘the’ treatment to go for.

Alloy-Specific Band Saw Setup Improves Finish Quality at Everising

Saws like band saws and circular saws are the time-honored way to cut raw material into useable forms for further machining in industrial applications. Saw cutting is not a simple process. However, as each alloy has different speed and feed requirements to maximize surface quality and minimize waste.

In the video above, we learn how Taiwanese companies like EVERISING MACHINE CO. are advancing industrial saw technology, with company president Shu-Chai Chiao.

 

“We collect many country’s standards,” Chiao said, explaining how the company stays aware of the cutting requirements of different alloys.

 

“Every country, every manufacturer, has one number. This is a lot of data that we must collect in our computer side, which we can then put in our machines to choose materials. For example, if we’re using a United States standard, we can use that to get information and know what standard component is inside. This information includes cutting data, so we can make it easy to cut the material.”

 

EVERISING builds their own machine tools in-house, and so designs them to minimize vibration, noise and temperature.

 

To achieve the smoothest of cuts, EVERISING joined together with a saw blade manufacturer and developed their machines to properly lubricate the saw blades while in contact with the material.

 

“The cutting surface, whether it becomes smooth or rough is also really important,” Chiao continued. “Our band saws are strong enough and have enough reach that it’s easy to get that smooth cut. We joined together with a saw blade manufacturer and we worked on a solution to lubricate the blades during the cut. We need this for an improved cutting surface. The saw blade, the teeth angle and the way the teeth cut are really important for us.”

Self-Tapping Screws: How They Work and How to Use Them

When looking for fastening solutions, one common solution to use for routinely maintained products is self tap screws.

 

What Is A Self Tapping Screw?

 

Self tapping screws are fasteners that are designed to drill their own hole as they are screwed into wood, plastic or metal. By using a screw driver and self-tapping screws, precisely fitted threads are created. Self tap screws are ideal for items that require regular maintenance and work well when working with two different kinds of material being fastened together.

 

These screws either come with a blunt, flat, sharp or piercing tip. Sharp-tipped self tapping screws drill their own holes in softer wood and plastic. However, it is helpful to drill a pilot hole when working with harder material. When drilling a pilot hole, make sure to use a smaller bit than the screw so it may still serve its purpose.

 

What material is involved can help determine what type of self tap screw will work best. There are two types: thread-forming and thread-cutting. Thread-forming screws are usually used when working with plastics. Thread-forming screws are designed to stay in place tightly, but over tightening the screw could result in materials breaking under too much pressure. Thread-cutting screws are used mostly when working with metal and wood. One drawback to using thread-cutting screws is that the threads may strip if the application is disassembled. This prevents reuse of the fastener and requires a new, slightly larger self tapping screw when it is time to reassemble.

 

However, there is a solution to prevent stripping. A metal insert can be installed from the beginning that would allow the self tapping screw to be regularly fastened and unfastened. These metal inserts also work to help minimize stress and expand as the fastener is screwed in.

 

Just like other types of fasteners, self tapping screws are available in all shapes and sizes and are also available in numerous different head types. When choosing the right self-tapping screw for any given application, it is important to consider the length of the screw tip. In order for the screws to serve their purpose and work properly, the screw must be drilled fully into the material before threading can begin.

 

Although self tapping screws are typically more in terms of price, they can help cut down on time and labor costs and combine the steps of drilling and fastening.

 

To learn more about where to find high quality self tap screws, please visit Fu Yeh, the professional screw manufacturer in the industry.

3 Must Have Woodworking Machines for Every Workshop

If you are an aspiring woodworker, who wants to take up woodworking professionally you should give ample thoughts to buying essential woodworking machines that you will need to carry out woodworking projects efficiently. Just like any other craft, woodworking begins with mastering the basic skills and knowledge to use the fundamental tools efficiently. Of course, a lot depends on the kind of projects you want to take up. But make sure that you invest in the essential woodworking machinery gradually. This way you will be able to assess if you really need a particular machine or not. As you gain more experience in the field, you will be able to find more specialized tools that allows you to do more things efficiently.

 

In this article we will not discuss about the basic hand tools that you will need to get started in woodworking, rather we will concentrate on choosing the power woodworking tools, which will take your woodworking experience to a whole new level. The first three woodworking machinery, that we would recommend any aspiring woodworker are: a table saw, a portable planer and a plunge router. With these, you will be able to carry out a number of tasks, right from milling, joinery and shaping.

 

These Three Different Pieces Of Woodworking Machinery Are Very Important:

 

  1. The Table Saw:

 

A table saw is at the heart of every woodworking workshop. There are several reasons why it has that coveted place among the woodworking machinery you have in the workshop– it not only allows great precision in ripping a stock in straight lines but is also useful in cutting it at various angles. It does the basic milling of a stock with ease and is well suited for joinery works.

 

When choosing a table saw, there are a number of factors that you need to consider. The first thing you need to understand is that – it is going to be one of the most used machinery in your workshop, so you must always buy a quality one. The work surface of the table saw should be rigid and strong, and should be able to sail through all types of projects. Ideally, you should buy one that has a handle to raise and lower the blade easily, and another handle that will enable you to adjust the angle of the blade. Another essential feature that it must have is the connection for dust collector. It should have powerful motor that will let you cut through hard wood and make deep cuts. The blades of the table saw are incredibly sharp, so they should come with a blade guard and a power switch that is within easy reach while working on it. Many table saw today come with a paddle switch that can be pressed with your knee or foot if you need to shut it down in an emergency.

 

  1. The Surface Planer:

 

A surface planer is another indispensable woodworking machinery to have in a woodworking workshop. It can help you to be incredibly creative in the work you do by smoothing any rough saw stock to your desired thickness. Gone are the days when a stock was hand planed tirelessly to get the designed thickness and smoothness, a surface planer can help you get the same result in a short time. Typically, a planer has a table of the dimension between 10” to 14” on which you can feed your stock. There are a set of blades that rotates, thereby cutting the wood as it is fed through it. You can adjust the depth of the cut b using the crank at one end of the planer.

 

Another important feature that you should consider having in your surface planer is a dust vacuum. This machine generates a lot of dust, so having a dust collection system in place with lengthen its life. This machine is quite noisy when it is at work, so always wear hearing protection when you are using it. If not used with care, it can be dangerous too. So, adhering to the safety precautions is of prime importance.

 

  1. The Router:

 

Every professional woodworking will have a router in his workshop. It is one of those wondrous pieces of woodworking machinery that can carry out a number of tasks for you – not only trimming and decorative edge treatments but also various joints like mortises, rabbets, and dadoes. By having a router in your workshop, you are adding versatility in your woodwork. By making use of patterns, you can create identical parts from wood.

 

A router makes use of various bits to produce a number of shapes. For beginners, a stationary base router is good enough. It will help you make cuts at a depth you make before making a cut. For advanced woodworkers, a plunge router can add a creative touch to the work. The plunge router bites into the wood, makes the cut and then allows you to lift it back. When choosing a router, choose one that is at least 2 HP or it won’t be powerful enough to carry out various tasks for you. You should also choose one that comes with variable speed. Collet size is another feature to consider. It is important if you want to use various bit sizes. It is important to remember that smaller bit can be put into larger collet size but not vice versa. The power should be within the reach of your fingers, and you should not need to take your hands off the router to switch it on or off.

 

Other than these 3 woodworking machinery, there are a few other power tools that you can consider buying. One is a good jigsaw. It is a very useful tool that can help you in varied tasks like cutting curves. When buying one look out for one that comes with blade guides as it will help in keeping the deflection of the blades to a minimum. Apart from that a handheld drill and a quality random orbit sander with a provision for dust collection are great power tools to have in your arsenal. Quality of these tools should always be of prime importance when choosing these tools and one should always remember to adhere to the safety norms while using them.

How to Shut Off Your Home Gas Supply Valve

Shutting off utilities such as your home’s water supply or electrical power is fairly common—something you do whenever making a repair or upgrade. Shutting off your natural gas supply is not something that occurs very often, but there are still times you may need to shut off the gas supply in your home. Knowing how to do this is important, because when it’s necessary, it may need to be done in a hurry.

 

Reasons for Shutting Off the Gas

The main shutoff valve controlling you home’s natural gas supply may come into play during major construction or renovation involving gas lines, when closing up or shuttering a home, to prevent possible flood damage. Or, in rare instances, you may need to shut off the gas valve when a gas leak is suspected inside the home.

 

Once the valve is turned off, however, do not turn it back on by yourself. It must be turned on by a qualified person such as a gas company service technician or a licensed plumber. To be a “qualified person,” you must be able to confirm proper operation of all pilot lights and gas appliances once the gas valve is turned back on.

 

Location of the Main Shutoff Valve

The main gas shutoff valve is located next to the natural gas meter supplied by your utility company. Your gas meter may be located outside your home on an exterior wall, or it may be found inside your home on an outside wall—often in a basement or utility area, such as a garage or the mechanical room where the furnace or water heater are located.

 

How to Shut Off the Main Gas Valve

The main gas shut off valve is a large valve located next to the natural gas meter. If the valve handle is parallel to the gas pipe, then the gas supply valve is open and the gas is on.

 

  1. To close the valve, use a clamping plier, an adjustable wrench, or an open-end wrench, and turn the valve handle 90 degrees so it is fully perpendicular to the gas line. It is a good idea to keep a wrench handy for this purpose and keep it located next to the shutoff valve.

 

NOTE: Many natural gas meter valves provided by a utility company have a hole in the handle that will line up with a corresponding hole in the valve body when the gas valve is in the closed position. The utility company will use the hole to lock and/ or seal the valve in a closed position when the gas account is closed. When the holes in the valve handle are lined up, it indicates the valve is in the OFF position.

 

  1. To ensure sure the gas shutoff valve is, in fact, fully closed, note the dial numbers on the meter face and write them down. Then check back in about 10 minutes. If the numbers have not changed, then you know that the shutoff valve is fully closed.

 

If you want to gain more information about shut off valves, I recommend that you can visit Alpha Brass Controls: www.alphabrass.com. Their on / off valves are manufactured from the best quality Brass and verified and tested under the highest quality standards. All Alpha Brass Controls valves are 100% MIT and 100% leakage tested to ensure the standards of quality and safety. More details, try to send inquiry to them.

6 Common Problems with Mesh Office Chairs

Ever since the Aeron chair burst onto the scene many years ago, mesh office chairs have been extremely popular. Mesh chairs are very unique; from their original styling, to the way the user feels when they sit. Because of their popularity, almost all office chair manufacturers now have their own version of a mesh chair. This means that the market is now flooded with mesh chairs ranging from cheap import chairs to very high end ergonomic chairs that are made to order in the USA. The mesh office chair topic is very polarizing as can be expected with any popular item. People seem to either love mesh chairs or hate them. In this article, we will share with you the downsides to mesh office chairs and the reasons why they are not a fit for every customer.

 

Before getting started it is important to understand that there are three distinct types of mesh office chairs. The first type is a mesh seat and back with no padding. Mesh is simply stretched across a chair frame on the seat and back. The second type is a mesh back with a padded mesh seat. This chair will have a seat that feels like a typical padded office chair but the backrest will have mesh stretched across the frame. The third type is a padded mesh seat with a padded mesh back. These models use the mesh upholstery for looks, which creates a feel very similar to traditional office chairs.

 

  1. Mesh Seats with No Padding Can Sag or Be Too Stiff

One of the biggest problems with a mesh chair is that it is very difficult to design a mesh seat that is both comfortable and supportive. A mesh office chair will almost always be too soft or too hard. Most higher-end mesh chairs will be upholstered with a soft mesh while lower-end chairs will typical have a hard mesh. A softer mesh will be more comfortable initially for the user. It will feel smoother and will expand further which can create a more comfortable sit. The mesh will sink down a bit more and give the user the feeling of floating; this is something that many mesh chair users rave about. But, mesh that is allowed to stretch and contract a substantial amount over and over will eventually sag; this can lead to the customer having to replace the seat or whole chair. The other major problem with soft mesh is that expands and contracts more than hard mesh so it will not properly disperse your weight over the entirety of the seat. Instead, the mesh will create an uneven flex point that causes the majority of the pressure to be placed on the tailbone. This can cause pain, numbing or discomfort after using the chair for an extended period of time.

 

A hard mesh will be much more consistent in its performance over time but the comfort level is very low to begin with compared to soft mesh. The flex point described above will not be nearly as pronounced but there will be no chance that the user experiences a feeling of floating. The seat will be much too hard not to notice the seat. A hard mesh seat will feel similar to sitting on a surface like wood than a typical office chair constructed of foam and fabric.

 

Suggestion: Some products with soft mesh seats, linked above, have become incredibly popular. We recommend only using these types of chairs for less than eight hours per day with multiple rest intervals throughout the day to get out of the chair and walk around; this will help to reduce the tension caused to the tailbone as described above. We do not recommend chairs that feature a hard mesh seat.  There are many alternatives out there that allow a user to pair a mesh back with a padded fabric, leather or vinyl seat; this will result in a more comfortable sit as well as a more cost effective option.

 

  1. Mesh Can Be Abrasive to Skin and Clothing

Mesh upholstery is much coarser than leather or fabric upholstery so there is a higher chance for the coarse material to cause abrasions to the skin or damage to clothing, such as dress pants. It is important to understand that there is a wide range in the quality of mesh used on office seating. Better quality mesh will be soft and smooth compared to lower quality mesh. This helps to reduce the likelihood of skin irritation or clothing damage. Mesh is upholstery made completely out of man-made materials, unlike leather. In some instances, the polypropylene, polyethylene, nylon, PVC or PTFE can cause skin irritation to the user.

 

Suggestion: Our first recommendation is that users with any type of allergy to polypropylene, polyethylene, nylon, PVC or PTFE should avoid mesh office chairs because of the discomfort it may cause to skin. We also recommend periodically checking your clothing for any wear being caused by the mesh. This is especially important on items such as dress pants, dress shirts or clothing made from soft materials like silk. Our final recommendation is to avoid having bulky or bulging items like a wallet or cell phone in your back pants pocket. Extra wear can often be found in areas where bulky objects are present.

 

  1. Mesh Is Difficult To Clean

Cleaning options with mesh are going to be more limited than other chair upholsteries. Non-padded mesh can easily be dusted with a vacuum; however, cleaning the chair with paper products like napkins, paper towels or toilet paper will be more of a nuisance than a help. The mesh upholstery will shred the paper products and add to the mess. Using a cloth towel and water can also be a bit risky because the friction caused by scrubbing with a towel combined with getting the mesh wet may make the mesh fray or split apart. Padded mesh will be even more difficult to clean. Along with the problems of using paper products or a cloth towel and water, padded mesh will also be very difficult to vacuum since many of the dust, dirt and food particles will be in-between the mesh and seat foam.

 

Suggestion: Prevention is going to be the best method to keep your mesh chair clean. Avoid things that will add to the potential of the chair becoming dirty, such as: eating at your desk or wearing dirty clothes/uniform in the chair. Try to keep the area around the chair as clean as possible to reduce dust and dirt that can become present on the mesh. If you do need to clean the mesh, first try a vacuum. Make sure to be very gentle and avoid pressing down on the mesh. Let the vacuum hover just over the mesh. If a towel and solution is necessary, then gently rub the dirtied spot with a soft cloth and soapy water and allow to air dry.

 

  1. Mesh Is Not Versatile

Mesh isn’t usually the preferred choice of designers because it limits their ability to customize a space to their taste. There are many different mesh chairs on the market but most of them have very similar looks with a very limited color selection. Mesh is mesh and there isn’t really a way to dress it up. Some manufacturers offer different color options but the ability to choose between different patterns in order to create a unique office design isn’t going to be as easy as it is with fabric chairs.

 

Mesh is not a good option for industrial, manufacturing and warehousing applications because the mesh will act as a net, trapping small materials that will be very difficult to remove. Things like metal shavings, sawdust and chunks of plastic can damage the mesh or cause injury when someone unknowingly uses a mesh chair with an object lodged into it. Workers in these environments often carry tools that can be sharp or strong enough to puncture or rip the mesh when the user sits down. This is another hazard for a mesh chair in an industrial environment.

 

Chairs with mesh seats are not ideal for call centers or 24/7 work areas, like dispatch rooms. Mesh seats are not built to withstand the constant wear and tear of a round-the-clock application and are also not comfortable for 8-12 hours shifts due to the challenges mentioned above.

 

Suggestion: We recommend that mesh chairs be limited to applications like offices, schools and conference rooms. Mesh chairs fit better in these areas because the user is often sitting in the chair for a couple hours at a time and the environment will not be destructive to the chair.

 

  1. Mesh Creates a Cooler Office Environment

The biggest selling point for mesh office chairs is always the breathability. Airflow and keeping you cool is touted as the biggest positive by almost every mesh chair manufacturer. This selling point is only a positive for limited applications and users. If you live in a place like Florida or Arizona and your office has the windows open, then the breathability of mesh seems like the only way to go. For someone living in a cooler climate like Minneapolis or in a work area that has the air conditioning on high, then the breathability of mesh seems like a moot point and can be a disadvantage. Unless your office environment is warmer than a typical office environment, which is usually around 68-74 degrees, then the “cooling effect” of mesh is no longer an overall positive.

 

The breathability and “keeping you cool” selling point is also rarely a positive for half of the people using a mesh chair, which are women. Studies have shown that women feel cooler on average compared to their male counterparts. [i] Women are more likely to be chilly when men are comfortable, and more likely to feel comfortable when men are warm. Mesh chairs only exacerbate this problem and will often cause women to be uncomfortable due to being too cold.

 

Suggestion: We do not recommend purchasing mesh chairs solely due to their ability to keep the user cool unless the environment is abnormally warm compared to a typical office. If you decide to use a mesh chair it’s important to keep in mind that you may require warmer clothing to stay comfortable.

 

  1. Frame Can Be Uncomfortable

Since most mesh chairs are designed with little to no padding, the frame can often become more pronounced to the user. On a padded office chair upholstered in leather or fabric, the user will not come into contact with the chair frame because the foam padding will spill over the frame making for an even sit over the whole seat. Mesh chairs will be constructed by stretching the mesh over the chair frame and since there isn’t padding, the user’s legs, butt, back or shoulders may come into direct contact with the chair frame which can be uncomfortable. Another problem that may occur is reduced blood flow to the lower legs due to the front of the chair seat frame cutting off circulation. Some chair models do a better job than others to help alleviate this problem. A waterfall seat shape is a design that has a seat front that drops off dramatically which helps to reduce poor circulation. Other chair models may place a small piece of foam on the chair front only, in an effort to help reduce this problem.

 

Suggestion: Look very closely at the chair frame with respect to the mesh around it. If there is a thick plastic frame that is visible outside of the mesh, then there is a strong chance that the problems described above will be present. Try avoiding these types of chairs. If you have already purchased a chair with these problems and are looking for relief, then try placing a folded piece of clothing or small piece of foam over the portion of plastic that is causing discomfort.

 

Final Thoughts

While there are many positive aspects to mesh office seating, the negative aspects can often be too overwhelming to justify going with a mesh office chair over a standard office chair. It is important to consider many factors in the work environment if mesh is going to be the ideal choice. Who is going to be sitting in the chair? What length of time will the chair are used per day and per sitting session? What is the average temperature in the work environment? Is the customer okay with limited colors and designs? For specific applications and users, mesh can work out great but it may not be the best fit for everyone.
