Plastic injection mold cooling system design
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 […]
slider cooling channel construction in mold injection
Why do we need slider cooling channel in mold injection? A slider core used to solve undercut of product. It is separate with a core and cavity plate. As you know, in injection molding process, molten plastic was ejected into mold by high pressure of cylinder. Temperature of molten plastic will heat up slider core. If […]
Injection molding design construction slide core
Slide core injection molding solve undercut in the products. This post will explain construction and design of it. How does slide core work? I. Construction of slide core system. Two pictures below will explain construction of slide core system. 1. Product. 2. Cavity plate. 3. Slide locking block: It uses to assemble an angular pin […]
