Polymer Injection Molding

From the first synthetic billiard balls to current biocompatible implants and aerospace metal replacements, polymeric materials have come a long way in the 100+ years since their first formulation. Today a myriad of materials is available to suit nearly every application, and when an off-the-shelf solution is inadequate, PTI Tech will custom formulate one that does.

From commodity plastics to highly engineered resins, PTI Tech is a leader in the analysis, selection, formulation, custom compounding, processing, and molding of plastics for precision high-performance applications. Some polymeric material highlights:

  • Engineering Resins: PEEK, PEI (Ultem™,) PPSU (Radel®,) Acetal (Delrin®) PPA (Amodel®,) PPS, PEKEEK, PLA, PMMA (acrylic,) PVOH, PVA, POM, PES, PMP, PBT
  • Ionomer Industrial Resins: PC, ABS, PC-ABS, PVDF, EVA, CPVC, Tefzel™, TPE, HDPE, Nylon
  • Commodity Resins: PP, PS, PE, PET, LDPE

Process

Image describes Polymer injection molding process: Formulation, compounding, and extrusion of polymer pellets Drying, then melting of the polymer pellets Shear and compression of the injection molding machine screw to liquefy the polymer at high pressure Injection of molten polymer at high pressure (5,000-20,000 PSI) into mold tooling Cooling and ejection of molded polymer components

Highly efficient, net shape polymer injection molding process includes the following:

  • Formulation, compounding, and extrusion of polymer pellets
  • Drying, then melting of the polymer pellets
  • Shear and compression of the injection molding machine screw to liquefy the polymer at high pressure
  • Injection of molten polymer at high pressure (5,000-20,000 PSI) into mold tooling
  • Cooling and ejection of molded polymer components
