How to deal with car mold skin grain break difference?

Automotive mold skin break is a common mold manufacturing problem, it is usually due to improper mold surface treatment or mold processing errors caused by.

A series of measures need to be taken to deal with the automotive mold skin grain break, the following are some suggestions:

(1) Confirm the mold material:
First of all, we need to confirm the material of the mold in order to choose the appropriate treatment method. Generally speaking, steel and aluminum alloy are commonly used mold materials, which have different physical and chemical properties, so different treatment methods are required.

(2) Surface treatment:
The die surface is treated to improve its hardness and wear resistance. Common surface treatment methods include carburizing, nitriding, chrome plating, etc. These methods can improve the hardness and wear resistance of the mold to varying degrees, but also lead to small cracks or breaks on the surface of the mold.

(3) Processing optimization:
Optimize the mold processing process to reduce the error in the process. For example, in the processing process to maintain a stable cutting speed and cutting depth, to avoid excessive cutting force resulting in cracks or breaks on the mold surface. In addition, the use of suitable coolants and lubricants can reduce cutting heat and friction, reducing the risk of cracks or breaks on the die surface.4) Repair measures:

If the mold surface has been broken, it needs to be repaired. Common repair methods include welding repair, filling, grinding and so on. These methods can choose the appropriate repair method according to the size and location of the skin break difference. During the repair process, attention needs to be paid to protect other parts from damage, while ensuring that the surface quality after repair meets the requirements.

(5) Preventive measures:
In order to prevent the appearance of the automotive mold, a series of measures can be taken, such as strengthening the quality control of the mold material, optimizing the mold structure design, and improving the processing technology level. In addition, regular inspection and maintenance of the mold is also an important measure to prevent skin wrinkles.

In short, the treatment of automotive mold skin grain break needs to consider a variety of factors, including mold material, surface treatment, processing technology, repair measures and preventive measures. Only in these aspects are reasonable treatment and control, in order to effectively solve the problem of automotive mold skin break.
