What Is FEP Injection Molding?
FEP injection molding производственный процесс, который формирует 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 (Тефлон), making it ideal for harsh environments.
To simplify its core meaning, here’s a breakdown of key terms:
| Термин | Объяснение |
| 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, теплостойкий, and electrically insulating properties. |
| FEP plastic molding overview | A versatile method for producing both small, замысловатые части (НАПРИМЕР., micro sensors) and large, high-volume components (НАПРИМЕР., проволочная изоляция). |
Суммируя, 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 (НАПРИМЕР., PP or ABS), FEP has unique melting and cooling needs—our expertise ensures consistency.
Key Process Steps & Parameters
| Шаг | Описание | Critical Parameter | Target Value |
| 1. Resin Preparation | Сухой FEP resin grades for molding Удалить влагу (moisture causes defects). | Drying Time/Temperature | 4 hours at 120°C |
| 2. Таяние | Heat resin in the injection unit. | FEP melt temperature window | 290°C – 380°C (554°F – 716°F) |
| 3. Инъекция | Force molten FEP into the mold. | Injection Pressure | 800 – 1,200 bar |
| 4. Охлаждение | Solidify FEP in the mold. | In-mold cooling for FEP | 10 – 15 секунды (varies by part size) |
| 5. Демольд | 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.
