Electrophoretic coating processing skills
Electrophoresis coating processing technology emerged with the development of my country's machinery industry, meeting people's requirements for high-quality vehicles. The use of electrophoretic coating processing technology can improve the safety, environmental protection and diversity of vehicle fasteners. When processing vehicle fasteners, it is necessary to master the application skills of electrophoretic coating processing, so as to ensure the production of fasteners Parts meet customer needs and can also play a larger application role in production.
Regarding the application skills during electrophoretic coating processing, first of all, it is necessary to test the high-strength 8.8 and 10.9 bolts for automobile chassis, engine, and transmission according to the types and performance requirements of automobile fasteners. The plan mainly includes black cathodic electrophoretic coating, hardware electrophoretic coating for fastener coating; there is also black cathodic electrophoretic coating, the formula is adjusted to be suitable for fastener coating; after that, it is black cathodic electrophoretic coating, ordinary Electrophoretic coatings for electronic products for the coating of parts.
Then, when it comes to the application skills of electrophoretic coating processing, the key is to pay attention to testing several main properties of the fastener coating (plating), mainly including corrosion resistance (salt spray test) performance and hot flash resistance. And assembly performance.
One thing to note here is that at present, domestic high-strength fasteners for automobiles basically rely on imports, and an important bottleneck in the localization of fasteners is the control of friction coefficient. On the premise of ensuring that the assembly performance is satisfied, the longer the salt spray test and the resistance to hot flashes, the better. In addition, the paint film does not fall off when assembled with a pneumatic wrench. These are the key technologies for the electrophoretic coating process of fasteners.
