The wall thickness of plastic parts processing has a great influence on quality.

It is very important to determine the wall thickness of plastic parts reasonably. 

The wall thickness of a plastic part is first determined by the use requirements of the plastic part: including the strength of the part, quality cost, electrical performance, dimensional stability, and assembly requirements. Generally, the wall thickness has an empirical value, which can be determined by referring to similar (such as Irons generally have a wall thickness of 2mm, and vacuum cleaners generally have a wall thickness of 2.5mm). The points to note are as follows:


a. The wall thickness of the plastic parts should be as uniform as possible, avoid too thin, too thick, and sudden wall thickness changes. If the wall thickness changes are required for the plastic parts, a gradual change or arc transition should be adopted, otherwise, the plastic parts will be deformed due to uneven shrinkage. , Affect the strength of plastic parts, affect the fluidity during injection molding, and other molding process issues.
