Design injection mold cooling system is very important. Cooling time is the longest circle in injection molding process, it takes up 50~80% of molding circle. Molten plastic has high temperature, If we don’t make cooling channels, the molding circle is very long, it is cause of molded defect as bending, sink marks, weld line, short […]

nx assembly add new component and constraints
This tutorial will explain how to add new component to an assembly and constraint between components in a nx assembly drawing. I. General assembly concepts. There are two concepts to creating an assembly structure. + Top-down modeling: Create component parts at the assembly level. + Bottom-up modeling: Create individual models in isolation, then later add […]
