Unscrewing mold cavityWhenever internal and sometimes external external threads are required on a plastic part, unscrewing molds are needed.

Molded plastic gears including 3 from unscrewing moldsSome plastic parts, such as caps and closures with detailed threads, cannot be removed from the mold using standard ejection methods. These molded parts must be carefully unscrewed from the injection mold to avoid damaging the threads during removal.

Unscrewing molds provide a highly reproducible solution for plastic components that require threading.

At Prodigy Mold& Tool, we specialize in the manufacture of high-quality unscrewing plastic injection molds for threaded parts. We produce long-lasting molds that can increase your speed, productivity, and accuracy, with higher cavitations and faster cycle times.
