Mold design and injection molding processing Guide

The appropriate die steel shall be selected according to the application requirements. In the case of prototype fabrication, hardened die steel is not required. In most cases, pre hardened steel or aluminum is usually used to reduce costs and facilitate mold adjustment during the prototyping stage. These soft metals can also mold enough test pieces and prefabricated parts. Pre hardened die steel (such as P-20 or nakr-55) is often used to make large-scale dies because it is impractical to harden die steel in large applications.

Injection mold manufacturing can be roughly divided into the following steps:
1、 Process analysis of plastic products.
Before the mold design, the designer should fully analyze and study whether the plastic products comply with the injection molding processing principle. It is necessary to carefully negotiate with the product designer and reach a consensus. It includes the necessary discussion on the geometry, dimensional accuracy and appearance requirements of products, so as to avoid unnecessary complexity in mold manufacturing as far as possible.
