Analysis of the impact of wall thickness on product quality in mold injection molding

Author: MULAN - Plastic Molding Manufacturer

Injection molding came up with the development of synthetic resin, and it promoted each other with plastic machinery. Plastic parts processing is a general term for various processes that convert synthetic resin or plastic into plastic products. The process generally includes plastic ingredients, molding, machining, joining, modification and assembly.

The following injection mold processing manufacturers will introduce to you the impact of wall thickness on product quality. The product wall thickness has a great impact on quality. If the wall thickness is too small, the flow resistance is large, and large and complex plastic parts are not easy to fill the cavity. . The smaller size of the wall thickness should meet the requirements of the following aspects: 1. It has sufficient strength and rigidity. 2. It can withstand the impact and vibration of the demoulding mechanism during demoulding.

3. Can withstand fastening force during assembly. Excessive wall thickness not only wastes raw materials, but also increases the molding time for injection molding, and is likely to cause incomplete curing. For thermoplastics, the cooling time is increased.

In addition, it will affect the quality of its processing. The wall thickness of the same product should be as uniform as possible, otherwise additional stress will be generated due to uneven cooling and solidification speed. It is very important to determine the wall thickness reasonably. It first depends on the use requirements of plastic parts: including the strength of components, quality cost, electrical performance, dimensional stability and assembly requirements.
