The residual liquid medicine and additives in the precision stamping parts spit out, and the tin layer attached by electroplating is easily corroded by these substances. Cause surface oxidation, resulting in yellow coating.

Inadequate treatment and not drying the workpiece can also lead to yellowing of the coating.

The adhesion of tetravalent tin, excessive additives, zinc impurity pollution in plating bath (less likely), insufficient coating thickness, iron impurity pollution (not easy to be found in the plating process), storage environment. These are the reasons that lead to the yellow of precision metal stamping parts.

Die is an essential process equipment in stamping process, which plays an important role in product quality, product life extension and production efficiency. It is difficult to meet the production demand because the die often wears and loses its working size in the production process. So it is very important to improve the durability of the mould.

Metal stamping parts are now very common in China, and there are countless manufacturers, large and small. In the stamping process of hardware stamping parts, if you don't pay attention, the surface is easily damaged, then how to solve this problem?

Install guards. Due to the small production batch, safety protection devices must be installed in the stamping operation which can not realize automation or use safety stamping tools, so as to prevent injury accidents caused by operation errors. All kinds of protective devices have their own characteristics and use range. If they are not used properly, injury accidents will still occur. Therefore, it is necessary to make clear the functions of various protective devices so as to ensure the correct use and safe operation.

Reform process, mould and operation mode to realize manual operation outside mould. For mass production, we can reform the process and mould to realize mechanization and automation. For example, the use of automation, multi station stamping machinery and equipment, the use of multi cutting tools and mechanized into the production device, the use of continuous mold, compound mold and other combined process measures. All these can not only ensure the safety of stamping operation, but also greatly improve production efficiency.

Improve stamping equipment to improve production safety and reliability. At present, there are many unsafe factors in the control system and electrical control system of many old stamping equipment. If they continue to be used, they should be technically reformed. Hardware stamping equipment manufacturers should improve product design to ensure the safety and reliability of stamping equipment.

The big feature of metal automobile stamping parts is that they have high dimensional accuracy, uniform size with the module, good interchangeability, and can meet the general assembly and use requirements without further machining. Moreover, the appearance of metal stamping parts is smooth and beautiful, which provides convenient conditions for surface painting, electroplating, phosphating and other surface treatment. Therefore, many manufacturers choose this kind of stamping parts Stamping method.
