What Is Polybenzimidazole (PBI) Moulage par injection?
PBI injection molding is a specialized manufacturing process for creating ultra-durable parts using Polybenzimidazole (PBI)—a high-performance polymer renowned for its exceptional thermal and chemical resistance. Unlike standard thermoplastics, Polybenzimidazole molding focuses on melt-processable PBI resins that can withstand extreme temperatures (up to 427°C heat deflection) while maintaining structural integrity.
À la base, high-temperature PBI service transforms PBI resin (often reinforced with fibers) into precision components via controlled high-heat injection. Notre PBI resin definition simplifies this technology: we explain how ultra-thermoplastic molding (PBI’s category) differs from conventional processes—emphasizing its ability to produce amorphous PBI molding parts with zero creep at 300°C and ultra-low off-gassing, critical for aerospace and semiconductor use.
Termes clés dans PBI polymer injection inclure:
- Melt-Processable PBI: PBI resins modified for injection molding (contre. traditional compression molding).
- Amorphous PBI: Non-crystalline structure that enhances dimensional stability at high temps.
Aerospace PBI Molding: Specialized PBI parts designed for space, aviation, et applications de défense.

The Polybenzimidazole (PBI) Processus de moulage par injection
Le PBI injection molding process is a highly controlled sequence optimized for PBI’s unique properties (high melt temp, sensitivity to moisture). Below is a step-by-step overview with critical parameters:
Étape 1: Préparation des matériaux
- PBI Drying: Raw PBI resin (Par exemple, Celazole® U-60) subit 4 hours of drying at 200°C to remove moisture—critical for avoiding bubbles (PBI absorbs 2% moisture by weight, which causes defects).
- Manipulation de la résine: Stored in sealed, dry containers to prevent reabsorption before molding.
Étape 2: Injection Setup
- Faire fondre: 400–430°C (hotter than most engineering plastics; requires specialized heating elements).
- Température de moisissure: 200–230 ° C (maintained via oil heating to prevent premature cooling).
- Barrel & Screw: Inert-gas barrel (nitrogen-purged) to prevent resin oxidation; low shear screw (20:1 L/D ratio) to avoid thermal degradation.
Étape 3: Injection & Monitoring
- Hot-Runner Valve Gate: Precise flow control; maintains PBI melt temp (410±5°C) to ensure uniform filling.
- Vacuum Venting: Removes trapped air (common in thick-walled parts); reduces defects by 95%.
- Temps de séjour: Limité à < 5 minutes (short residence time) to prevent PBI degradation.
Étape 4: Post-Molding
- Recuit: 24 hours at 250°C to relieve internal stress (critique pour tight-tolerance PBI parts).
Stress-Relief Cycle: Refroidissement lent (5° C / heure) Pour éviter la déformation; ensures dimensional stability at 300°C.
