Husky Injection Molding Systems Ltd., Bolton, Ont., rolled out the first model in its new Quadloc-Tandem-Index (QTI) large press line capable of stack or multi-component operation. Introduced as a concept last year at the K 2004 show in Dusseldorf, the new 3500-ton model combines Husky’s Quadloc two-platen large-machine series with its Tandem stack-molding technology and components from its Index PET preform machine with a rotary center platen. A part can be molded in one mold face, indexed to the second mold face by rotating the center stack 180°, and overmolded with a second color or resin. Or the user can mold separate parts in each mold face without rotating the center stack. A main benefit of QTI is that it can use conventional molds. It also saves floor space because the second injection unit is mounted on a rail beside the press so that it travels with the moving platen. This allows the injector to remain connected to the mold sprue. The rotating platen, which can support 75,000 lb on each of its core sides, rotates 180° in about 2.5 sec. The first QTI machine is going to Tier 1 automotive parts manufacturer Lear Corp. of Southfield, Mich., for making instrument panels.
