Product Description:
 

Square shaped shims and round shims are two common fasteners, mainly used for connecting the gap and stress distribution between bolts, nuts and connecting parts to reduce friction, limit deformation, transfer pressure and prevent air and liquid leakage. Their main differences are as follows:

1. Shape: square shims are in quadrilateral shape with equal side lengths and 90-degree angles; round shims are round with uniform circumferential edges.

2. Application scenarios: square shims are suitable for certain square or regular structural connections and bolt holes due to their shape characteristics, mainly used for track connections such as angles, I-beams and rails, etc.; and round shims are suitable for a wide range of scenarios and are more commonly used than square shims.

3.Material: both can use a variety of metal and non-metallic materials, such as: steel, copper, aluminium, rubber, silicone, etc., just for different working conditions have to choose different materials.

4. Installation effect: due to the round gasket edges for the continuous circumference, by the distribution of stress is more uniform; square gaskets corners of the place of the relative concentration of the force, which may lead to local overloading of the corners of the parts. 

5. Torque control during installation: In general, it is easier to control the torque during installation of round shims because of their uniform pressure distribution; however, square shims may require stricter torque control during installation to avoid overloading at the corners.

6. Possibility of stress concentration: Square shims have four corners, while the edges of round shims are circumferential, so that when subjected to stress, square shims may be subjected to stresses more uniformly than round shims of the same material. Possibility of stress concentrations: Square shims have four corners, whereas round shims have circumferential edges.

processing methods for gaskets:

Wire Cutting Process

Wire EDM is a process in which a fine metal wire is energised and the heat generated melts the metal. The wire does not come into direct contact with the material, and even highly hard metal materials can be cut. In addition, since the sheet metal can be cut in layers, shims of the same shape and different thicknesses can be processed at the same time. Another advantage is that no burrs are produced because electrical discharge rather than contact machining is used. On the other hand, it has the disadvantage that the processing speed is slower than other methods such as laser processing, making it suitable for small-lot production.

Laser Processing

Laser processing is a commonly used method for processing sheet metal. This processing method is not only suitable for gaskets with high dimensional accuracy and complex shapes, but also for various other parts. Laser processing uses the heat energy generated by the laser beam to melt the metal for cutting and processing. The thinner the material, the faster the processing speed; however, if the material is too thin, deformation will occur. Most metals around 0.05 to 2mm can usually be processed. The processing speed is slow and not suitable for mass production. In the manufacturing industry, it is usually used for processing a small number of parts such as fixtures and equipment, as well as trial products for development.

Applications

1, the basic knowledge of stainless steel
Stainless steel is an alloy material with corrosion resistance, and its main components are an alloy of elements such as iron, chromium and nickel. These elements can effectively resist oxidation and corrosion, so that stainless steel has a high degree of durability and aesthetics.
2, stainless steel maintenance methods
Cleaning
Keeping stainless steel products clean is an important part of their maintenance. You can use mild detergents and soft cloth for cleaning, avoid the use of detergents containing acidic and alkaline components, so as not to damage the surface of stainless steel. When removing dirt, you should try to avoid using irritating cleaning tools to avoid scratching the stainless steel surface. After cleaning, rinse with water and dry with a clean soft cloth.
3, the use of stain remover
For some stubborn dirt, you can use special stainless steel stain remover for cleaning. But before using it, you should carefully read and follow the instructions in the product manual. In addition, stainless steel products on the dirt can be cleaned with alcohol or vinegar, these common cleaners on stainless steel has a certain decontamination effect.
