ANAHEIM, CALIF. - Apex Machine Tool Co. in Farmington, Conn., is working its way into the world of superinjection molding as the sole U.S. supplier of molds for the high-pressure, close-tolerance Japanese TechnoPlas injection molding machine, according to John R. Bruno, Apex's vice president for plastics. The company has made 12 tools to date for the Tokyo-made machine, which features mold injection pressures of 45,000 pounds per square inch, Bruno said. This allows the combination of both thin and thick wall configurations within the mold for materials ranging from polyetheretherketone, acrylics and glass-filled nylon, Bruno said.
Extreme machinery demands require Apex to produce molds with tolerences of 0.0002 inch for the machine, he said.
Along with superinjection mold work, Apex has just invested $500,000 in a Char-milles Roboform 40 conventional electric discharge machine, complete with 24-station tool changer, and a Daewoo ACE-V65 vertical machining center, according to Bruno.
