KYLE Views:195 Release time:2024-04-01

The core supports in an injection mold are often referred to as "Core Pins" or "Support Pillars." Core pins are typically cylindrical and are used to create a void in the plastic part or to support the core from collapsing or flexing under the pressure of the injected plastic. They are usually made of hardenable steel because they experience a significant amount of stress during the molding process.

Support pillars, on the other hand, are used in the mold base to support the cavity and core blocks, preventing them from flexing or bending under the force of the molding press.
