How To Ensure The Quality Of Silicone Rubber Sealing Ring For Cars?

In the field of electrical appliances, performance testing and product life is the most important link, and in the new energy industry, the performance and life of silicone seals can not be ignored, it may directly affect the life safety of each of our drivers, so a small part of nature may also produce certain quality problems. So do you know how to distinguish between its material and performance?

1. Material differentiation

First of all, for the distinction of materials, at present, the new energy automobile industry basically uses automotive special silicone rubber or fluorine silicone, so the performance of some materials may be low in aging and high and low temperature and positive combustion level, resulting in many cars in the early assembly test without problems, and as time goes on, people gradually begin to age, resulting in various problems in the car. So the choice of material is more important, we need to distinguish our understanding of the material, under normal circumstances, ordinary glue and phase glue already have a certain difference, and many now basically use the specified automotive silicone rubber, different rubber silicone molecular composition, performance is naturally different, so be sure to distinguish which is more suitable for your silicone material!

2, material hardness and performance

The choice of softness and hardness is also the key to it, many new energy materials do not have an accurate choice in hardness, such as soft products after assembly, resulting in rolling off

There is a problem in the circuit of the rectifier product, and the product is hard, which leads to the deformation of the main body after the force compression, resulting in the main body loosening and even leaking, and the hardness is too high

High lead to long-term force impact and damage and other phenomena, so moderate hardness and softness must be tested in many aspects and later determined!

3. Structural problems

Structural design is also its key problem, many new energy seals are special-shaped parts, and it is difficult to find whether it will be squeezed after assembly in the process of assembly

The deformation or assembly has gaps, and the mold can not be processed in the early stage of the silicone products manufacturer, the most important of which is the mold structure is difficult to release, resulting in silicone manufacturers

The appearance and quality of the product during production are poor, the parting line is large, the edge is broken, the pulling is broken and so on can not meet the requirements after assembly.

Performance stability, such as plasticity, specific gravity, strength resistance, elongation, shrinkage, etc., the most important thing for automotive silicone seals is stability, in the early stage

Stability after the test, many products can meet the standard during the test, but there are still deformation, tear, extension and other phenomena after use, so in

All aspects of performance can reach the temperature of the case can be selected for long-term use!
