What Is FEP Injection Molding?
FEP injection molding es un proceso de fabricación que da forma FEP (Fluorinated Ethylene Propylene), a thermoplastic fluoropolymer, into custom parts using injection molding technology. Unlike other plastics, FEP combines the flexibility of polyethylene with the chemical inertness of PTFE (Teflón), making it ideal for harsh environments.
To simplify its core meaning, here’s a breakdown of key terms:
| Término | Explicación |
| FEP thermoplastic molding | The process of melting FEP resin (a thermoplastic) and injecting it into molds to form parts. |
| Fluorinated Ethylene Propylene molding meaning | Creating functional components from FEP, a material prized for non-stick, a prueba de calor, and electrically insulating properties. |
| FEP plastic molding overview | A versatile method for producing both small, piezas intrincadas (P.EJ., micro sensors) and large, high-volume components (P.EJ., aislamiento de alambre). |
En breve, FEP injection molding turns raw FEP resin into tailored parts that thrive in applications where other plastics fail.

The FEP Injection Molding Process: Step-by-Step Excellence
Achieving high-quality FEP parts requires strict control over every process step. Unlike common plastics (P.EJ., PP or ABS), FEP has unique melting and cooling needs—our expertise ensures consistency.
Key Process Steps & Parameters
| Paso | Descripción | Critical Parameter | Target Value |
| 1. Resin Preparation | Dry FEP resin grades for molding Para eliminar la humedad (moisture causes defects). | Drying Time/Temperature | 4 hours at 120°C |
| 2. Fusión | Heat resin in the injection unit. | FEP melt temperature window | 290°C – 380°C (554°F – 716°F) |
| 3. Inyección | Force molten FEP into the mold. | Injection Pressure | 800 – 1,200 bar |
| 4. Enfriamiento | Solidify FEP in the mold. | In-mold cooling for FEP | 10 – 15 artículos de segunda clase (varies by part size) |
| 5. Fundamento | Remove the part from the mold. | FEP degating technique | Automated cold degating (minimizes part damage) |
| 6. Finishing | Trim excess material and inspect. | FEP mold shrinkage control | 2.5% – 3.5% (controlled via mold design) |
Other critical factors:
- FEP screw & barrel design: Specialized hard chrome-plated barrels prevent FEP degradation (FEP is abrasive at high temps).
FEP molding cycle time: 30 – 60 seconds for small parts; 2 – 5 minutes for large, thick-walled components.
