Unscrewing Molds

Unscrewing Closure Molds are designed for caps and closures with detailed threads that cannot be ejected using bump-off methods.

Upon molding, these parts are unscrewed from the mold to avoid thread damage.

COPAR designs unscrewing molds with optimized cooling thus ensuring short cycle time.

COPAR has manufactured a large number of unscrewing closure molds for high cavitation (up to 48 cavities).

Our design is well proven to have excellent cooling property and a good water seal on the rotating cores.

COPAR is a Lebanese factory for plastic molds and mechanical engineering founded in 2005

In order to enhance customer satisfaction, grow business and produce a consistent quality product, COPAR decided to implement a quality management system conforming with ISO 9001:2008 standards.
