When design a plastic injection molding part, we have to say thickness is a very important thing which should be pay more attention to, it will effect the design can come true or not.

Uniform wall thickness minimizes both shrinkage and residual stress in the final part. If completely uniform walls simply aren’t an option, gradual thickness variations are essential to maintaining design stability.

The wall thickness of the plastic parts is determined by the requirements of the plastic parts, which include the strength, quality cost, electrical performance, dimensional stability and assembly requirements. The general wall thickness has its experience value.
