What Is PFA Injection Molding?
PFA injection molding est un processus de fabrication qui façonne PFA (Perfluoroalkoxy), a melt-processable fluoropolymer, into custom parts using injection molding technology. En tant que PFA melt-processable fluoropolymer, it combines PTFE’s (Téflon) 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:
| Terme | Explication |
| 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. |
En bref, 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 (point de fusion élevé, low viscosity when molten) require specialized process control. Our step-by-step approach ensures consistent, high-quality parts every time.
Key Process Steps & Paramètres critiques
| Étape | Descriptif | Critical Parameter | Target Value |
| 1. Resin Preparation | Dry PFA resin grades for molding to eliminate moisture (moisture causes bubbles/voids). | Drying Time/Temperature | 6 hours at 150°C |
| 2. Fondre | 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. Injection | Force molten PFA into the mold—low viscosity requires slow, steady pressure to avoid flash. | Injection Pressure | 600 – 1,000 bar |
| 4. Holding & Refroidissement | Maintain pressure to fill mold cavities fully, then cool to solidify PFA. | In-mold cooling for PFA | 15 – 25 secondes (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. Démoulage & Finishing | Remove parts and trim excess material (gates/runners). | PFA degating technique | Laser degating (for micro parts); automated cold degating (standard parts) |
| 7. Contrôle de qualité | Verify dimensions and surface finish. | PFA mold shrinkage control | 3.0% – 4.0% (adjusted via mold design) |
Other vital details:
- PFA screw & barrel design: Hardened steel barrels with chrome plating (resists PFA’s abrasive nature) and low-compression screws (prevents resin degradation).
PFA molding cycle time: 45 – 90 seconds for small parts; 3 – 7 minutes for large, thick-walled components (par ex., PFA chemical processing fittings).

PFA Surface Treatment: Boosting Functionality
PFA’s natural non-stick surface is perfect for many uses, but some projects need better bonding, printability, or adhesion. Notre PFA surface treatment services solve these challenges without compromising PFA’s core properties.
PFA Surface Treatment Methods: But & Résultats
| Méthode de traitement | Objectif | Measurable Result |
| Plasma treatment for PFA | Increase surface energy to improve adhesive bonding | Surface energy: 40 – 48 dynes/cm (depuis 22 dynes/cm untreated) |
| Chemical etching PFA parts | Create micro-roughness on the surface for stronger bonds | Bond strength: 18 – 24 N/cm (tested per ASTM D1002) |
| PFA surface activation | Break down fluorine-carbon bonds to promote ink adhesion | UV ink retention: 98% après 2,000 heures d'exposition aux UV |
| Adhesion promotion PFA | Prepare surfaces for bonding to dissimilar materials (par ex., verre) | Peel strength: 5 N/cm (contre. 1 N/cm for untreated PFA) |
