What Is PFA Injection Molding?
PFA injection molding производственный процесс, который формирует PFA (Perfluoroalkoxy), a melt-processable fluoropolymer, into custom parts using injection molding technology. Как PFA melt-processable fluoropolymer, it combines PTFE’s (Тефлон) extreme chemical resistance with the moldability of thermoplastics—filling a critical gap for applications needing both durability and design flexibility.
To clarify key terms, here’s a simple breakdown:
| Термин | Объяснение |
| PFA thermoplastic molding | Melting PFA resin (a thermoplastic) and injecting it into molds to create functional parts. |
| Perfluoroalkoxy molding meaning | Producing components from PFA, a material valued for heat resistance, non-stick properties, and biocompatibility. |
| PFA plastic molding overview | A versatile method for making everything from tiny microfluidic parts to large industrial fittings—all with consistent quality. |
Суммируя, PFA injection molding turns raw PFA resin into tailored components that outperform most plastics in extreme conditions.

The PFA Injection Molding Process: Step-by-Step Control
PFA’s unique properties (высокая точка плавления, low viscosity when molten) require specialized process control. Our step-by-step approach ensures consistent, high-quality parts every time.
Key Process Steps & Критические параметры
| Шаг | Описание | Critical Parameter | Target Value |
| 1. Resin Preparation | Сухой PFA resin grades for molding to eliminate moisture (moisture causes bubbles/voids). | Drying Time/Temperature | 6 hours at 150°C |
| 2. Таяние | Heat resin in the injection unit—PFA’s high melting point demands precise temperature control. | PFA melt temperature window | 350°C – 420°C (662°F – 788°F) |
| 3. Инъекция | Force molten PFA into the mold—low viscosity requires slow, steady pressure to avoid flash. | Injection Pressure | 600 – 1,000 bar |
| 4. Держащий & Охлаждение | Maintain pressure to fill mold cavities fully, then cool to solidify PFA. | In-mold cooling for PFA | 15 – 25 секунды (varies by part thickness) |
| 5. Venting | Release trapped air to prevent defects—critical for PFA’s low gas permeability. | PFA venting & decompression | 0.02mm vent gaps; 50 bar decompression pressure |
| 6. Демольд & Finishing | Remove parts and trim excess material (gates/runners). | PFA degating technique | Laser degating (for micro parts); automated cold degating (стандартные детали) |
| 7. Проверка качества | Verify dimensions and surface finish. | PFA mold shrinkage control | 3.0% – 4.0% (adjusted via mold design) |
Other vital details:
