What Is Polybenzimidazole (PBI) Инъекционное формование?
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.
По своей сути, high-temperature PBI service transforms PBI resin (often reinforced with fibers) into precision components via controlled high-heat injection. Наш 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.
Ключевые термины в PBI polymer injection включать:

- Amorphous PBI: Non-crystalline structure that enhances dimensional stability at high temps.

The Polybenzimidazole (PBI) Процесс литья впрыска
А 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:
Шаг 1: Материал подготовка
- PBI Drying: Raw PBI resin (НАПРИМЕР., Celazole® U-60) подвергается 4 hours of drying at 200°C to remove moisture—critical for avoiding bubbles (PBI absorbs 2% moisture by weight, which causes defects).
- Обработка смол: Stored in sealed, dry containers to prevent reabsorption before molding.
Шаг 2: Injection Setup
- Расплавлять температуру: 400–430°C (hotter than most engineering plastics; requires specialized heating elements).
- Температура формы: 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.
Шаг 3: Инъекция & 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%.
- Время резиденции: Ограничено до < 5 минуты (short residence time) to prevent PBI degradation.
Шаг 4: Post-Molding
- Отжиг: 24 hours at 250°C to relieve internal stress (критическое для tight-tolerance PBI parts).
Stress-Relief Cycle: Медленное охлаждение (5° C/час) Чтобы избежать деформации; ensures dimensional stability at 300°C.
