Ok, let's take care of it, the mold is also to be done. Today, we will introduce the selection and design of mold bases in the production of plastic molds.


1. The standard mold base is preferred, and it is executed according to QJ/MM03.01 "Standard Plastic Formwork".

6.450T injection molding machine above the mold, the template should have a ring hole on all four sides, there must be a mold angle between each template


7. If it is possible to generate a large side pressure (cavity depth exceeds 50mm), the non-standard large formwork should be designed with the original body.
