Radel Injection Molding with Action Plastic Injection Molding
High-Performance Medical-Grade PPSU Components
At Action Plastic Injection Molding (Action Mold & Tool), we have decades of experience molding Radel® (Polyphenylsulfone, PPSU) for demanding applications where durability, chemical resistance, and sterilization cycles are critical. As a family-owned, ISO 13485 Certified injection molding company with over 30 years in business, we produce precision Radel components for medical devices, aerospace systems, and industrial applications that must perform under pressure.
Why Radel Injection Molding?
Radel offers a rare combination of impact strength, heat resistance, and sterilization durability that makes it a leading choice for reusable, high-performance parts.
Key Advantages:
- Superior Sterilization Resistance – Endures over 1,000 autoclave cycles without cracking, discoloration, or property loss.
- Outstanding Impact Strength – Significantly higher than PSU or PEI for long-term durability under stress.
- Excellent Chemical Resistance – Resists disinfectants, industrial solvents, and aggressive cleaning agents.
- High Heat Resistance – Continuous-use performance at up to 400°F (204°C) with a UL 94 V-0 flammability rating.
- Biocompatibility – Fully compliant with FDA and USP Class VI standards for medical use.
Our Molding Experts
Our Radel injection molding expertise supports multiple high-performance industries:
- Medical Devices – Surgical trays, dental tools, instrument housings.
- Aerospace – Interior components, ducting, and housings meeting FST (flame, smoke, toxicity) requirements.
- Semiconductor Manufacturing – Chemical-resistant fluid handling parts.
- Food & Beverage Equipment – Components that withstand heat and aggressive cleaning agents.
Custom Radel Compounding
In addition to molding standard PPSU materials, we can process custom Radel formulations to match your specific application requirements.
Options include:
- Glass-filled grades for enhanced stiffness.
- Custom colors for brand and product integration.
- Specialized formulations for sterilization or flame resistance.
Our engineering team works directly with clients to identify the right formulation, ensuring that your Radel component meets performance, compliance, and cost goals.
