Bayer Corp. of Pittsburgh has developed a polycarbonate that maintains high melt flow processing at temperatures lower than the 550§ F typical for injection molding PC. The new Makrolon allows in-mold decorating technology for visual appeal in Ford Motor Co.'s 1996 Taurus and Mercury Sable control panel bezel. The resin's lower processing temperature does not damage the polyester film substrate during in-mold decoration. The film's maximum temperature stability is 500§ F during processing.
SPM Inc. of Anaheim, Calif., injection molds the bezel. It uses inmold decorating technology from Nissha Printing of Japan. A photoelectric eye in the mold ensures precise decorating film placement in the mold.
When the polycarbonate is shot, in-mold heat and pressure transfer the inks, textures and hardcoat from the film to the PC.

AlliedSignal Inc. has expanded its nylon 6 product line to include tougher grades that can reduce cycle times by as much as 30 percent.
The Morristown, N.J., firm claims its UltraTough Capron HPN resins flow in the mold and freeze off faster than conventional resins but have equal or better strength properties. The wide processing window allows lower temperature processing, which can improve surface appearance. AlliedSignal offers glass levels of 15-40 percent and can supply a grade with 40 percent mineral reinforcement.
