What to do when corrosion of friction gaps occurs during CNC processing of aluminum alloy

People should conduct an appearance check on this first batch of aluminum alloy die-casting parts with poor shortcomings to see if the surface layer of the casting parts has caused a rough surface in some parts.

The reasons for friction and crevice corrosion in the production and processing of aluminum alloy die castings are given:

(1) The position and appearance of the inner runner caused by the die-casting mold are not good;

(2) Inadequate water cooling in the strong erosion of aluminum alloy profile liquid at the inner runner caused by forging standards.

The ways to deal with and avoid corrosion of friction gaps are:

(1) Improve the location and orientation of the inner runners where the internal watering is improperly poured;

(2) Improve the water cooling standards, which is very important to improve the strong erosion of metal material liquid;

(3) Corrode part of the gap to enhance building paint;

(4) Adjust the water flow rate of aluminum alloy liquid so that it does not cause air pockets

(5) Remove aluminum alloy adherents from the abrasives.

The production and processing of aluminum alloy die castings actually cause friction and gap corrosion! Don’t worry, you can reasonably prevent such things from happening according to the left and right methods.
