Understand the processing technology and quality control points of rubber seals

As one of the common key components in the industrial field, rubber seals play an important role in various mechanical equipment and engineering projects. Its processing technology and quality control directly affect the performance and reliability of seals. This article will introduce the key points of rubber seal processing technology and quality control to help you better understand and apply rubber seals.

Key points of processing technology

Material selection: The performance of rubber seals is closely related to the material selected. Common rubber materials include nitrile rubber (NBR), fluorine rubber (FKM), acrylic rubber (ACM), etc. It is crucial to choose the appropriate material based on the actual working environment and requirements.

Mold Design: The processing of rubber seals often requires custom molds. Mold design should take into account the shape, size, sealing surface structure and other factors of the seal to ensure that the final product meets the design requirements.

Molding process: Molding is one of the key steps in rubber seal processing. Common molding processes include calendar molding, injection molding, extrusion molding, etc. Choosing the appropriate molding process can ensure the molding accuracy and consistency of the seal.

Vulcanization treatment: Vulcanization is an important part of rubber seal processing. Vulcanization can improve the wear resistance, aging resistance and elasticity of rubber. Controlling parameters such as vulcanization temperature, time and pressure is the key to ensuring product quality.

Quality control points

Dimensional accuracy: The dimensional accuracy of a seal directly affects its sealing performance. Dimensional tolerances should be strictly controlled during processing to ensure that product dimensions comply with design requirements.

Surface quality: The surface quality of the seal has an important impact on the sealing effect and service life. It should be ensured that the surface of the seal is smooth, free of bubbles, impurities and other defects to ensure its sealing performance in contact with accessories.

Material testing: Raw materials are strictly tested to ensure they meet relevant standards and requirements. Common testing methods include tensile testing, hardness testing, oil resistance testing, etc.

Sealing performance test: The sealing performance of a seal is one of its most important functions. Pressure tests, vacuum tests, temperature cycle tests, etc. should be carried out to verify the sealing performance of the seals under different working conditions.

in conclusion

The processing technology and quality control of rubber seals are key factors to ensure their performance and reliability. Reasonable processing technology and strict quality control can ensure the stable quality and product consistency of seals. When selecting suppliers and partners, their processing techniques and quality management systems should be considered to ensure that products meet expected performance and standard requirements.
