What is the cause of the damage to the surface of the motor housing?

Aluminum shell is made of aluminum alloy as a variety of materials. With high flexibility, can be arbitrary depth of cut, there are usually internal circuit card slot, as long as the circuit board can be inserted directly, without fixed again, quick are other varieties of shell unmatched, aluminum shell is made of a casting skills, with water proof property, maintenance inside the electrolyte will not overflow, avoid dry solid electrolyte capacitor failure.

The conductive and thermal conductivity of aluminum shell is good to the conductivity and thermal conductivity of aluminum. Aluminum shell plastic raw materials are usually relatively simple, high hardness, many engineering plastics and even more than the strength of metal. For the cost and ease of thinking, lighter weight, small heat to buy a laptop can be a better planning of plastic cooling base. But if it is a larger component, the higher the heat is still recommended to buy the notebook metal materials work excellent heat dissipation base.

Cause of damage to the surface of the aluminum motor housing:

On the surface of the ingot, there are impurities or composition segregation. There are a lot of things out of the ingot surface segregation and ingot without homogenization treatment or homogenization treatment effect is not good, hard metal particles in ingot memory of a certain amount, in the extrusion process of metal flowing through the work zone, these metal particles segregation or hard to damage in the attachment of the work or work surface with the final to scratch the surface of profile;

Die cavity or work belt with debris, mold work with a low hardness, so that the work surface with the injury in the extrusion and scratch profiles;

There are hard inclusions in the exposed metal or graphite strip on the discharge track or swing bed;

When the cross bar is delivered from the discharge track to the swing bed, the profile is damaged due to the excessive speed.

Solution to surface damage of aluminum shell:

Strengthening the control of ingot quality;

To improve the quality of the mould, the mould is periodically nitrided and the nitriding process is strictly carried out;

The soft felt will profile and AIDS isolation, minimize the damage profile and auxiliary contact;

Production should be handled gently, as far as possible to avoid dragging or turning section.
