The thickness of the wall depends on the external force that the product needs to withstand, whether it is used as a support for other parts, the number of posts to be supported, the number of protrusions, and the plastic material selected. The wall thickness design of general thermoplastics should be limited to 4mm. From an economic point of view, too thick a product design not only increases material costs, prolongs the production cycle (cooling time), but also increases production costs. From the perspective of product design, excessively thick products increase the possibility of causing cavities (stomases), which greatly weakens the rigidity and strength of the product.
The ideal wall thickness distribution is undoubtedly that the cut plane has a uniform thickness in any place, but in order to meet the functional requirements, it is always inevitable to change the wall thickness. In this case, the transition from thick rubber to thin rubber should be as smooth as possible. Too abrupt transitions in wall thickness can cause dimensional instability and surface problems due to different cooling rates and turbulent flow.
