  • INJECTION MOLDED PULLEYS HAVING LOW LEVELS OF OUT-OF-ROUNDNESS
    Publication number: 20100184548
    Abstract: Injection molded plastic pulleys (10) reinforced with glass fibers (at least 15 weight percent) are provided which exhibit low levels of out-of-roundness. The low levels of out-of-roundness can be achieved without the need for machining through the use of disc gating and perimeter venting. The pulleys (10) have belt-engaging surfaces (15) whose out-of-roundness is less than or equal to 35 microns when measured at any location up to 1 millimeter from the outside edges (16) of the belt-engaging surface (15).
