Introduction of wall thickness requirements for plastic part

The wall thickness of plastic parts processing has a great impact on quality. If the wall thickness is too small and the flow resistance is large, it is difficult for large and complex plastic parts to fill the cavity. The dimensions of the wall thickness of plastic parts should meet the following requirements:

1. Have sufficient strength and stiffness;

2. Can withstand the impact and vibration of the demoulding mechanism when demoulding;

3. It can bear the fastening force during assembly.

The wall thickness value of plastic parts processing varies with the variety, brand and product size of plastic parts. Excessive wall thickness in the processing of plastic parts not only wastes raw materials, but also increases the molding time for thermosetting plastic molding and easily causes incomplete curing. For thermoplastics, it increases the cooling time. In addition, it will also affect the quality of plastic parts processing. The wall thickness of the same injection molded part should be as uniform as possible, otherwise additional stress will be generated due to uneven cooling and solidification speed.
