INJECTION MOLD DESIGN AND MOLD MAKING

Creative, cost effective, prototype and production molds have been a core skill and success factor for PPM for over 40 years. PPM is known for clever, cost effective mold designs and quality mold construction. The following PPM moldmaking approach and characteristics have been used successfully to build over 6,000 molds. Although well over 80% of molds are built in house, PPM has several very reliable low cost geographic zone sources that have a proven track record of making molds for PPM

• PPM designs and builds many types molds of molds as follows:
  • Single or groups of prototype molds in 4 weeks or less
  • Production molds(4 weeks-14 weeks)
    • Self contained, steel and/or aluminum
    • Mud-plate structured molds
    • Rounds or inserts to be installed in a mold frame
  • PPM has several niches or specialties in moldmaking that both demonstrate versatility and unique skills as follows:
    • The making of molds for a variety of insert molding applications, for a diverse range of applications
    • The making of molds for parts with internal and external threads, including automatic unscrewing molds
    • The making of molds for the “lost core” process, where the parts’ required geometries can not be created by molding in a straight forward open close, collapsible cores, or other conventional moldmaking method
    • The making of molds for bearing related applications, such as overmolding various bearing coatings and molds that produce industrial and aerospace tight tolerance bearing cages
    • The making of molds to overmold magnets into very precise positions for a number of different applications, including industrial pump impellers, fluid level detection floats and related devices, and other devices requiring magnetics
    • The making of molds to implement desired “metal to plastic” conversions, especially for aerospace and industrial applications
