Surface state mass control of parts

Before the electroplating enterprise accepts the entrustment of the parts manufacturing enterprise to process the parts, it should carefully implement the technical :

1. Seriously digest the design drawings of the parts, and find out in advance the various defects that may exist on the parts that hinder the obtaining of a good coating layer;

2. Carry out technical coordination with the design and manufacturing process departments of the parts, and implement the results of the negotiation on the drawings and technical agreements;

3. The electroplating enterprise shall inspect and accept the surface quality of the parts before plating according to the technical requirements stipulated in the parts drawings and technical agreements.


1. Seriously digest the design drawings of parts

In order to ensure the quality of the parts after plating, it is necessary to carefully digest the design drawings of the parts, and if necessary, understand the manufacturing process of the parts , so as to discover in advance the various defects that may exist on the parts that hinder the obtaining of a good plating layer. The design drawings and manufacturing process of parts should be carefully analyzed from the following aspects:

1. The influence of part shape on the quality of coating layer;

2. The influence of coating thickness on part size and fit accuracy;

3. The influence of surface defects that may occur during the part manufacturing process on the quality of the coating layer;

4. The requirements of the design drawings on the surface roughness of the parts, and the impact on the quality of the coating layer;

5. The influence of part structure on the quality of coating layer;

6. The influence of various metallurgical factors on the parts on the quality of the coating layer.


2. Seriously carry out technical coordination

In order to ensure the quality of the coating layer on the surface of the parts, it is necessary to coordinate the above analysis with the design and process departments of the parts . The main basis for technical coordination is not only the GB/T 12611-90 "Technical Requirements for Quality Control of Metal Parts Before Plating " standard, but also the practical experience obtained in the electroplating industry in long-term practice that conforms to scientific laws and is also an important basis for technical coordination.


3. Check and accept the surface quality of parts before plating according to the technical agreement

In order to do a good job in the quality control of the surface state of the parts before plating, the electroplating enterprises should carefully check and accept the parts sent from the parts manufacturing enterprises in accordance with the provisions of the technical agreement, one is to implement the results of technical coordination between the two parties, and the other is to maintain their own quality reputation .
