Due to the greatly varied market demands for molds and molded products, there are many kinds of changes and thus high requirements for us in such aspects as shape, size, material, structure and more, causing us many problems and difficulties in the production process of molds and products. How to effectively control the geometric dimensions of the mold and the product is just one of them.   For different types of molds and products, there are different control techniques and methods for dimensions control. Personally, I usually start from the following aspects.   Mold Design Control Firstly, we have to fully understand the technical requirements for the mold structure, material, hardness, and precision, etc., including whether the shrinkage rate of the plastic material is proper, and whether the 3D model of the product is complete, in a bid to perform reasonable analysis.   2. Thorough consideration should be given to various factors that may influence the ...
