Multi-mold carrier system raises press capacity.

A new Multi-Parting Line (MPL) tooling system from D-M-E Co., Madison Heights, Mich., lets molders double the cavitation of standard single-face molds without needing a larger press. The MPL system is a line of components for three types of configurations: stack molds, dual mold carriers (two independent single-face molds with nearly the same shot weights that open and close simultaneously), and tandem molds (two separate molds with different materials, shot weights, and cycle times that open and close alternately).

The tandem mold system is licensed from Injection Moulding Innovations of Versmold, Germany. Its center section has two rotating shafts with bayonet locks on each end that mate with external locking bolts on the moving and stationary platens. The shaft movements are synchronized by a toothed belt outside the center plate. The belt simultaneously locks one bayonet bolt while unlocking the other. The tandem system is a cold-runner system, while the stack and dual-mold-carrier systems employ hot runners. Tel: [phone], www.dine.net
