Misumi Standard Stavax Combinable Thread Core Mold Parts with High Finished for Cosmetics Plastic Die/Mould

Description Of Thread Core Plastic Components

Thread Core in a plastic component allow for fastening of your plastic part to another plastic part or to a non-plastic part by using common fasteners. Plastic components can have Thread Core on the external side or internally.

External threads can be modified so that they can be molded without any special mold actions. Internal thread core require a rotating core that unscrews from the part. Unscrewing molds are used for plastic parts that have thread core or ridges that cannot be easily injected using the standard knockout method. In these molds, the parts are unscrewed from the mold to avoid thread core damage.

Unscrewing-molds remain the most complex of all injection molds and need to move at high speeds and clear previously molded parts efficiently in order to begin the next cycle. They require tremendous technical savvy to build and maintain. They are designed for many years of production, which is why they are considered a long-term investment when producing high-volume parts.
