Milan, Italy-based Plastimac SpA recently introduced machinery for blown film and extrusion blow molding
The PB30/S blow molder produces containers as large as 8 gallons, using 30 tons of clamping force. The mold holding plates slide on horizontal, overlapped linear guides, using roller plates. Plastimac said roller plates give highly precise movements and reduce friction and wear. Proportional valves control the movement of both the mold plates and the nozzle.
A brushless electric motor/ball screw combination powers mold movement. Hydraulic power drives the clamping movement.
On the blown film side, Plastimac showed two single-layer blown film lines. New features include a cooling ring that optimizes air flow, with adjustable inserts designed for polyethylene film.
