Thermoplastic injection molding is a common procedure for precise technical plastic parts with complex geometries. A wide palette of thermoplastic plastics (polyamides, polycarbonates and polyethylenes) are available with a range of different chemical and mechanical properties.
Nearly any color can be achieved through coloring or painting. Housing parts can be metallized to improve electronic shielding (EMC). Graining, patterns or engravings can be directly incorporated in the injection molding molds. Thermoplastic injection molding enables injection molded parts to be created with highly favorable dimensional accuracy and a high degree of reproducibility. Thermoplastic injection molded parts can be subsequently welded.
G.W.P. manufactures thermoplastic injection molded parts weighing 2 - 5,000 g using reciprocating screw injection molding machines with a compressive force up to 1,300 tons.
Plastics for thermoplastic injection molding
The plastics which are suitable for thermoplastic injection molding include acrylonitrile butadiene styrene (ABS), polyamide (PA), polycarbonate (PC), polyethylene terephthalate (PET), polyethylene (PE), polylactate (PLA), polymethylmethacrylate (PMMA), polystyrene (PS), polypropylene (PP), polyetherketone (PEEK), polyvinyl chloride (PVC) and other thermoplastics. Glass fiber-reinforced plastics can also be used.
