Repair motor housing aluminum extrusions scratch method do you know?

Update time : 2022-12-09 17:26:47

In our daily life, we can often see that the shell material of many electronic products is mainly motor housing aluminum extrusions. Motor housing aluminum extrusions has become one of the essential mainstream products in the electronic industry. But in the production of motor housing aluminum extrusions, it is easy to get bruised and scratched, and how is this to be repaired?

1. Due to improper stamping die design

The stamping damage is caused by the die itself; The mold is too tight, and the parts need to be pry open, which will cause gaps.

Solution: Enterprises must improve the quality of mold maintenance. The shell of aluminum profile processing must be nitrized regularly, and the nitrization process must be strictly carried out. Strictly control the quality of chemical composition of materials; Improve the mold repair quality, improve the mold manufacturing accuracy, regularly carry out the mold nitriding, strictly implement the nitriding process parameters.

2. Improper anodic oxidation operations

When anodic oxidation is hanging down, it is caused by hanging tools; When entering and leaving the storage tank, the oxidation tank is encountered; The product fell out of the can.

Solution: After anodizing, the aluminum casing is coated with a protective "coating." Because the anodic oxide film has very stable chemical properties in the natural environment, it can provide anti-corrosion protection for motor housing aluminum extrusions. Reasonable control of high hardness of anodized film will make motor housing aluminum extrusions with low roughness and smooth surface, so as to greatly improve the wear resistance of aluminum shell. If various organic and inorganic dyes are added in the anodizing process, so that the anodized film has color, to the motor housing aluminum extrusions brings a beautiful appearance.

3. Bruises and scratches in each process

Improper stacking collapse; motor housing aluminum extrusions are forcefully held and placed. The package containing motor housing aluminum extrusions contained debris. During transportation, debris will rub against the product, causing scratches.

Solution: Use felt and plastic strips to separate profiles and accessories from motor housing aluminum extrusions to reduce friction between them and cause damage. Timely clean the discharge track, bed and other work belt to avoid impurities affecting the quality of aluminum shell production and processing.
