A patent-pending device from Uniloy Milacron, Tecumseh, Mich., modifies parison thickness in specific angular positions and thus reduces the weight and cycle time of extrusion blow molded containers. Instead of expensive and fixed-size flexible die rings, Uniloy’s new Thickness Compensation System (TCS) uses a different approach to modify dynamically the die gap in the final section of the head, according to Marco Solinas, Uniloy product manager for industrial applications. Further technical details are expected in a presentation at the SPE’s annual Blow Molding conference Oct. 9-11 in Toledo. Net-weight savings up to 8% and a cycle-time reduction of 12% to 18% have been achieved with TCS, Uniloy reports. The device is priced competitively vs. other approaches like flexible die rings. It can be installed on extrusion heads for both accumulator and continuous-extrusion machines. Two Uniloy machines with the TCS option have been sold to makers of drums and jerry cans in South America and the Far East. Uniloy is also retrofitting five extrusion heads for a U.S. molder of jerry cans. Tel: (517) 424-8756 * www.uniloy.com
