Used Spot Welders Cost-Effective and Economical

Posted on by

Resistance welding is commonly used for joining steel sheets. These machines have evolved over the years. There is no metal filler needed, and the heat for the weld pool is created by means of resistance when a high welding current is directed through the welded work pieces. This technique is a highly efficient production method that is particularly well-suited for automated mass production and production lines.

 

Resistance welding is ideal for small batch production because this method is flexible, the equipment used is simple and the process is easy to control. Though these machines are highly priced they help provide quality welds, every time and at the required production rate. Seek the advice from the experts as they suggest the most cost effective and economical spot welders. Spot welding is one form of resistance welding. Spot welding focuses on specific points to weld and not on connecting the entire metal object. This technology allows you to perform repairs on previously welded objects.

 

Spot Welder is used in contacting metal surfaces welded by the heat from resistance to the electricity flow. Sheets having thickness of 0.5-3.0 mm are joined using this process. Determining the appropriate welding parameters is a very complex issue. A small change in one parameter has a major effect on other parameters as well. The contact surface of the electrode is gradually increasing making it difficult to design a welding parameter table. The table displays optimum parameters for different circumstances.

 

This kind of equipment takes care of almost all welding safety requirements for various industries and is also easy to install. Few industries where this equipment is used are heavy machinery and water equipment. Different metals of various thicknesses require different current amplitudes, time intervals and types of electrodes. For instance, if the equipment is not properly installed it could end up delivering too much or too little energy to the sheets being bonded. If too much of energy is delivered the sheets would melt excessively, which creates a whole in them rather than a weld. However, if the amount of energy is too little that will be insufficient to melt the metals and bond them.

How to Use a Tree Pruning Saw

Posted on by

Once you’ve decided you need to make a pruning cut and know that the wood is too thick for the otherwise-preferable use of hand pruners or loppers, it’s time to get out your tree pruning saw. Pruning saws are your choice for wood about 1.5 inches thick or more and your last resort before the very large stuff that you might only be able to do with a chainsaw. As such, they are used to cut a wide range on the large end of wood thicknesses.

 

Since saws are used on thick, often long wood, their use often comes with more cautions and considerations than pruners and loppers, which are basically strong and specialized scissors. Saws can require significantly more strength and control.

 

This guide covers tips and cautions for the use of saws in pruning you can reach from ground level.

 

Pruning with A Saw, General Technique

 

Wear sturdy work gloves and possibly safety goggles if you’re in a dense shrub.

 

Choose the exact spot to cut and a healthy cutting angle. As you prune, it may help to consider these steps:

 

  1. Notice nearby wood you want to preserve. Often you will be working in tight-angled crotches or near other branches you do not want to cut. More than any other pruning tool, saws easily slip and can quickly injure wood unintentionally, so note this risk in your mind.

 

  1. Choose a comfortable direction of cut. When possible, choose to cut from a top side to a lower side, so gravity is pulling the saw into the wood. By changing where you stand relative to the plant and the angle of your saw, you can usually make the same cut in many different ways to suit your access and comfort.

 

  1. Reduce limb weight with preliminary cuts. This step is crucial and not anticipated by many gardeners. Thick or long branches have significant weight that will cause a premature break and tear before you can complete a saw cut. This is because your saw cut will reduce the wood holding the limb to a weak, narrow strip. To prevent a tearing wound to the plant, you must tactically remove this weight before even starting your last cut at your chosen spot.

 

  1. Begin your final cut with a starting groove. Without this groove, tree pruning saws will want to slip away from your site. Slipping is especially a risk on non-horizontal branches.

 

  1. Begin to cut. Working in the groove to guide your strokes, you can cut at a brisk speed now, straight back and forth, keeping in enough control to not slip and wound nearby wood or yourself. Cutting happens on the pull stroke, so bite into the wood on pulling and push back lightly.

 

  1. Finish the cut. Saw until the branch comes cleanly away from the plant. Occasionally some rough wood will be left at the bottom of your cut, like a splinter beard. To achieve that perfect, baby-smooth cut, you can shave this off with a light stroke of your blade pressed flat against the pruning wound.

Comparison between Automotive Oil and Motorcycle Oil

Posted on by

Oil is quite essential for the smooth functioning of engines in both motorbikes and automobiles. However, there are different types of oils which have different types of viscosities and it should be chosen accordingly. In the past, engine oils used in cars and motorcycles varied hugely due to various factors. Nowadays, both cars and motorcycles are manufactured with revving engines that can use automotive oil without any bad effects.

 

Motorcycle oil VS Automotive Oil

 

Although both these can be used in bikes, the engines of both cars and motorbikes function are different and their require oils are specifically formulated. Compared to the car engine and bike oils are expensive. Most of the motorcycles include some important factors which enable better performance and durability of the motorcycles. Car oil is quite inexpensive compared to bike. Some of the major differences between these two types are elaborated below.

 

Viscosity:

Compared to the automotive and bike is thinner even though both these oils are classified under the same viscosity. This is made thinner so that it provides better and easier lubrication for small internal parts in the motorbikes.

 

Price:

It is quite expensive compared to car oil as it is highly refined. Bike oil is thoroughly refined so that it provides better lubrication and passes easily through small internal components in the vehicle. As it requires an extended refining process, it is quite expensive than the standard types of engine oil. However, it is important to purchase motorbike engine oil for vehicles as it guarantees better performance and higher durability of the engines.

 

Reduction of heat:

In comparison to the automotive oil, this oil is designed to reduce the amount of heat generated in the internal parts of the engine. Moreover, heat is generated in focal points in these engines compared to car engines.

 

Specifically formulated oil:

As compared to cars, bikes require specifically formulated one as oil breaks down faster in bikes due to the continuous meshing of gears. So all the motorbike engine oils are designed and formulated specifically for bikes.

 

Different additives:

Automotive do not contain additives which are present in motorbike engine oils. Various types of additives such as PTFE or Teflon are included in these to reduce excessive heat and friction. This is coated onto the gears of the vehicle.

 

Friction:

The engine oils used in bikes helps to reduce friction and thereby prevents clutch slippage. It can therefore be used effectively in vehicles with oil-wet clutches. But car engine seldom can be used to reduce slippage or friction.

 

However, when exposed to extreme pressure and heat, both these types of engine oil breaks down which further causes thinning of the oil. It then fails to lubricate the engines effectively.

 

Today with technological developments in various fields, different types of engine oils are made available quite easily in most of the online stores. Synthetic oil is another type of automotive oil used in most of the vehicles today.

Importance of Rubber and Ozone Test Chamber in Industries

Posted on by

Rubber is a versatile material that is used in various industrial and domestic applications. All across the globe, the natural rubber is extracted from trees. The natural rubber is very soft and is in a thick liquid form. Rubber of this kind does not have many usages. The natural rubber is purified and gives an end product called polyisoprene. Rubber of this kind can also be synthesized by artificial methods. The synthetic rubber has extensive industrial usage as compared to natural rubber.

 

They are used for making tires, household products, tubes, industrial hoses, industrial cushions and so forth. Rubber also has a high usage in the construction field for flooring, matting, etc. The material is also used extensively in manufacturing medical products such as surgical gloves, catheters etc. the molecular structure of rubber consists of a long interlinking polymer chains that make it ideal for usage in a vast variety of industries.

 

The Natural rubber is not completely fit for industrial usage hence the process of vulcanization is used to increase the properties and strength of the material by adding sulfur to it. After, vulcanization the strength of the material is increased significantly, making it fit for industrial usage.

 

As vulcanized rubber has extensive usage in industries, it is essential to test the various properties of the materials and the end product so that the manufacturers can ensure the best quality provided to their customers. There are many different properties of rubber that need to be tested before commencing the manufacturing process. This helps in avoiding enormous rejection of end products. These tests conducted on rubber include tensile strength, compressive strength, the effect of aging, etc. An important testing procedure that is conducted on rubber materials is testing under ozone environment – ozone test chamber is required at this moment.

 

An ozone test chamber is used for testing the effects of ozone on a rubber product or material under controlled conditions. When the rubber is exposed to ozone for a longer time, there are significant changes in the properties of the material such as breaking strength, tensile strength, etc. The ozone test chambers help in detecting the amount of change that takes place in a testing sample after it is exposed to ozone in the ozone test chamber.

 

Another major testing instrument that is used for quality testing of rubber is the shore hardness tester. A shore hardness tester is used to test the hardness of a rubber material under specific load. This helps in determining the viscoelastic properties of the materials and helps in predicting its suitability for a certain usage. The use of rubber products in today’s industrial scenario is inevitable, but proper testing procedures are essential to make sure that the best quality products are provided to the customers.

 

Ektron Tek, the leading manufacturer of testing equipment, helps their customers by providing the high-quality Ozone Test Chambers and assists them in enhancing their productivity. If you need further details about rubber testing equipment, welcome to contact us for more information!

Three Questions to Ponder When Choosing Office Desk Chairs

Posted on by

Office desk chairs should be more than functional and cost-effective. When sitting at a desk for hours at a time, the individual should not have to suffer from aches and pains due to stress placed on the joints or spine. With the proper seating, the concerns of sore muscles and joints can be eliminated. When it comes to personal comfort, choosing the right material can make a difference as well. With so many options for office chairs, how does one make the best selection? It’s a good idea to begin by asking the following three relevant questions.

 

  1. How Important Is Ergonomics and What Features Should Be Considered?

 

Proper ergonomics in the workplace, either at home or in a remote office location, should play a pivotal role when choosing furniture. Office desk chairs that are ergonomically designed are made to relieve stress on the spine and joints. This type of furniture is especially beneficial for workers who suffer from back pain, arthritis, or other painful conditions.

 

Lumbar support is a feature that should be considered. This helps keep the spine in proper alignment. Another important ergonomic feature is a reclining seat, which helps eliminate spinal pressure and stress. It’s a good idea to try it out before buying. Note whether the backrest supports the head while in the reclining position. This will help reduce strain on the shoulders and neck.

 

Ergonomic chairs also have armrests to eliminate strain on the arms and wrists, as well as an adjustable height that keeps feet positioned on the floor. The height should optimally be anywhere from about 16-21 inches from the seat to the floor.

 

  1. Which Material Is the Right Choice?

 

While the material one chooses is generally a matter of personal preference, it helps to consider the advantages of one fabric or material over another. Materials for office desk chair are most commonly done in leather (often seen in executive type seating), fabric, and vinyl.

 

While genuine leather is the most expensive of the three and may require periodic conditioning, it is made to last a lifetime. It is also more stain-resistant than some fabrics. Conversely, fabric materials are typically more affordable and often come in colors or patterns to complement the existing decor. When incorporated with mesh, it tends to be “breathable,” thus helping to keep the user cool and comfortable. It’s a good idea to have the fabric treated with a stain protection application. Lastly, vinyl or “faux leather” material is durable and made to resemble genuine leather at a fraction of the cost. Unlike leather, it will not require conditioning, and it may retain body heat as it is not very breathable.

 

  1. What Type of Casters Will Work Best?

 

To choose a chair with the most appropriate caster wheels, consider the type of floor it will be used on. For hardwood, tile, linoleum, or cement floors, rubberized or soft-wheeled casters will work best. For carpeted floors, hard casters are the best choice.

 

As a final thought, whenever possible, it’s a good idea to test a chair in the store or showroom before purchasing it. A display model on the floor should be available to try out.

 

VOXIM is the expert in manufacturing office desk chairs; we also provide lounge seating, executive chairs, task chairs, and public seating series products. Whether seeking office furniture seating of affordable excellence or any seating requirements, no one can go further than VOXIM.

What Is a Pneumatic Solenoid Valve?

Posted on by

A pneumatic solenoid valve is a type of standard electro-mechanical solenoid that, when activated by electrical power, opens a valve under positive or negative air pressure. In standard industrial applications, they have been used for many years as a type of on/off switch for pneumatically powered systems such as with air-powered drills. They have also been commonly employed in fluid control systems such as for releasing hot and cold water into a washing tub in an automatic washing machine, or for outdoor lawn sprinkler systems.

 

The pneumatic solenoid valve differs from the traditional solenoid in that the actuator controls a valve that is under some level of pressure. It can either function to release pressure and allow gas or liquid to flow when electrical current is applied, or the pressure itself can activate the valve in reverse and create an electrical signal that is channeled to a monitoring station.

 

Some pneumatic valve assemblies are also small control units that act as triggers for larger solenoids, and together these types of pneumatic solenoid valve designs are often referred to as a pilot valve or as a compressed air pilot valve. Pilot valves can be stackable, meaning that they can be arrayed in series on a pipeline or other fluid or gas flow assembly so that pressure and flow can be channeled at key points in an industrial process. A single pneumatic solenoid valve that is installed as a pilot valve also often has a manual level of actuator control. This means that the solenoid function of the unit, where the actuator opens and closes the valve, can be controlled manually by pushing a button or moving a mechanical arm. In more sophisticated industrial systems, however, the pilot valve unit is electrically controlled through a series of programmable settings for running power to the solenoid when needed to open or close the valve.

 

In automated industrial systems where large amounts of inaccessible pipeline exist that must be controlled remotely, pneumatic solenoid valve systems are often chosen, as they can be operated by ambient pressure that builds up in the system itself and they don’t require external power. This allows them to act as a type of safety valve to release pressure when needed, and, in the process, the mechanical motion of the pressure release can activate the electro-mechanical feature of the solenoid so that a brief electrical signal is transmitted to a control station to indicate that the valve state has changed. They also serve a reverse function where they can be opened or closed from the control station if an operator determines that a system is not performing properly.

 

Solenoid valve parts can range from very small units for rapid, micro-control systems, where they have a 0.4-inch (10-millimeter) diameter and can be run on low-level direct current (DC) voltages of 12 volts. High-power industrial level valves at the opposite end of the spectrum are made of strengthened steel alloys. They can handle pressures of up to 4,500 pounds per square inch (316 kilograms per centimeter squared) and temperatures as high as 1,200° Fahrenheit (649° Celsius).

 

SHAKO is leading and the largest professional pneumatic solenoid valve manufacturer. Our solenoid valves are available in 6VDC, 12VDC, 24VDC and 110/220VAC. If you need more details about solenoid valve series, welcome to visit our website and feel free to contact us!
