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.
