A guide that provides injection‑molding parameters, mold design advice, and troubleshooting tips for GE engineering thermoplastic resins.
This Processing Guide offers general injection‑molding parameters for all GE engineering thermoplastic resin families, covering mold design, material selection, drying, molding conditions, and troubleshooting. It also includes suggested best‑practice do’s and don’ts and references additional literature for specific resin grades.
The document lists common mold‑building steels, prototype tooling options, and recommended temperature ranges (425 °F to 800 °F) for processing GE resins. Contact information for GE Plastics literature requests and a list of worldwide sales offices are provided at the end.
| Processing temperature range | 425 °F to 800 °F |
|---|---|
| Maximum recommended mold temperature | 140 °F (60 °C) |
| Common mold steel hardness | Rockwell 55‑58 |
GE Plastics resins can be processed between 425 °F and 800 °F depending on the specific resin grade.
P‑20 steel is regarded as the workhorse of the industry and is commonly used for mold building.
Mold steel surfaces should have a hardness of Rockwell 55 to 58 for good wear resistance.
