The core technology of the seal production process is revealed
创建于04.27
A seal is a round component used to seal and prevent leakage of liquids or gases, and is widely used in a variety of industrial equipment and mechanical devices. The production process of seals is crucial to their sealing performance and service life. Here we will reveal the core technology of the seal production process.
First, the selection of raw materials
Seal ring raw materials are usually rubber, silicone, nitrile rubber and other elastic materials. In the selection of raw materials, you need to consider the use of sealing ring environment, media type and temperature and other factors, select the appropriate rubber material to ensure that it has good wear resistance, corrosion resistance and high temperature resistance.
Second, mold design
The key step in the production of seals is mold design, mold design directly affects the molding quality and dimensional accuracy of the seal. Mold design needs to take into account the shape of the seal, size, groove type and other factors, and need to be based on different material properties and production process requirements to design a suitable mold structure.
Third, the seal manufacturing process
- Rubber mixing: firstly, the selected rubber raw materials and additives are mixed, and after a certain time and temperature heating, the rubber particles expand and absorb the additives to improve the elasticity and toughness of the rubber.
- Extrusion molding: After mixing, the rubber material is extruded into a molding belt, which is extruded into the predetermined shape of the sealing ring through an extruder and cut into suitable sizes through a die.
- Forming & Vulcanizing: The extruded seal is put into the vulcanizing machine for vulcanizing treatment to enhance the elasticity and high temperature resistance of the rubber.
- Testing and screening: The molded seals are subjected to appearance inspection, size testing and quality screening to ensure that the seals meet the required quality standards.
Fourth, the sealing ring surface treatment
Seal ring surface treatment is an important part of its sealing performance and wear resistance. Common sealing ring surface treatment includes coating, vulcanization, sandblasting, etc. The surface treatment can improve the friction performance, anti-aging performance and corrosion resistance of the seal.
V. Quality Inspection
The quality inspection of seals is the key link to ensure its stable performance and reliable quality. Common quality inspection includes appearance inspection, dimensional accuracy test, pressure resistance test, wear resistance test, etc., to ensure that the seal's various performance indicators in line with the relevant standards.
In summary, the core technology of seal production process includes raw material selection, mold design, seal manufacturing process, seal surface treatment and quality inspection. Through scientific and reasonable process and strict quality control, high-performance seals can be produced to meet the sealing needs of different industrial equipment and mechanical equipment. Seal is an important part of mechanical equipment, its quality is directly related to the performance and service life of the equipment, so strengthen the seal production process research and technology to improve the quality of seals and the application of the effect is of great significance!
