The end cap of auto parts is a special auto part. The processing material of this part is generally made of stainless steel. However, after special processing technology, it can have good tensile strength, and has good plasticity and physical The performance has also been greatly improved, so it has a good shock absorption effect.
The following editor briefly introduces the production process of the end cover of auto parts for you:
1, preparatory heat treatment
The purpose of this step is designed for subsequent finishing, which can effectively improve the casting performance of parts and reduce internal stress. Common methods include annealing, normalizing and quenching and tempering.
2, post heat treatment
The purpose of this step is to improve the strength and hardness of the product. The methods that can be used include quenching, carburizing and quenching, nitriding and quenching.
In addition, we also need to pay attention to the fact that the objects we deal with in the above two steps are different. The first step is to pretreat the rough material; the second step is to process the processed product. And the car after these two steps The accessory end cap is the final product that we often see.
