What Effect Does the Wall Thickness of Plastic Parts have on Quality?

The wall thickness of plastic parts has a great influence on quality. When the wall thickness is too small, the flow resistance is large, and large and complicated plastic parts are difficult to fill the cavity. The minimum size of the wall thickness of the plastic parts processing should meet the following requirements:

1. Have sufficient strength and rigidity;

2. It can withstand the impact and vibration of the demolding mechanism when demoulding;

3. Can withstand the fastening force when assembling.

The minimum thickness of the injection molding factory is determined by the variety of plastic parts, grades, and product sizes. The excessive thickness of the plastic parts not only wastes the raw materials but also increases the molding of the thermosetting plastics. Time, and easy to cause incomplete curing; for thermoplastics, it increases the cooling time. In addition, it will affect the quality of plastic parts processing. The wall thickness of the same injection molded part should be as uniform as possible, otherwise, it will be due to cooling and Uneven curing speed produces additional stress.
