What is the wall thickness in plastic mold manufacturing?

The thickness of the wall depends on the external force that the product needs to bear, whether it is used as a support for other parts, the number of receiving posts, the number of extensions, and the plastic material selected. The wall thickness design of general thermoplastics should be limited to 4mm. From anChina Plastic Crate moulds Manufacturers economic point of view, excessively thick product design not only increases the cost of materials, extends the production cycle (cooling time), and increases production costs. From a product design point of view, an excessively thick product increases the possibility of causing voids (pores), greatly weakening the rigidity and strength of the product.

 

The ideal wall thickness distribution is undoubtedly the uniform thickness of the cut surface at any place, but in order to meet the functional requirements so that the wall thickness changes are always inevitable. In this case, the transition from thick rubber to thin rubber should be as smooth as possible. Too sudden wall thickness transition will cause dimensional instability and surface problems due to different cooling rates and turbulent flow.
