Introduction of screw maintenance issues by screw manufacturers

1、 Dongguan Screw Factory needs to be very careful when rinsing screws because this process is very important, as there will be residue left on the surface of the screws during this process. Rinse this step after cleaning with a silicate cleaning agent.

2、 During the tempering and heating process of screws, they should be stacked properly, otherwise slight oxidation may occur in the quenching oil.

3、 There will be white residue of phosphide on the surface of high-strength screws, indicating that (the first point) the inspection was not careful enough during operation.

4、 If Dongguan Screw Factory finds that there is blackening on the surface of the parts, resulting in chemical reactions, it indicates that the heat treatment work is not thorough and the alkaline residue on the surface has not been completely removed.

5、 Standard parts of components may rust during rinsing, and the water used for rinsing should also be frequently replaced.

6、 Dongguan Screw Factory introduced that excessive corrosion phenomenon indicates that the quenching oil has been used for too long and needs to be added with new oil or replaced.
