The machinery maker helped Wolfcraft develop the two-component handles for a manual sanding tool for plasterboard, from the early stages through production. The handles are soft to the touch.
Wolfcraft brought its injection molding in-house five years ago, to its plant in Dunajska Streda, Slovakia, achieving substantial cost cuts. Wolfcraft now has 12 injection presses, with clamping forces from 60-160 metric tons, all from Wittmann Battenfeld.
The new multicomponent press is equipped with Battenfeld's Airmould process for gas injection, and an integrated servo-electric rotary unit.
The first station molds the poly¬propylene body of the handle, using Airmould. Then the mold is opened and a rotary table moves the preform into the second position, where a thermoplastic elastomer is injected into the hollow part.
Wittmann Battenfeld is based in Kottingbrunn, Austria. Its U.S. operation, Wittmann Battenfeld Inc., is in Torrington, Conn.
