High-Temperature Injection Molding Services
We specialize in high-temperature injection molding for advanced engineering plastics requiring extreme thermal stability, mechanical strength, and long-term reliability. From prototype validation to stable mass production, our solutions support demanding industrial environments worldwide.
- Continuous service temperature above 260°C
- Dimensional tolerance down to ±0.05 mm
- Proven performance in high-load and high-heat conditions
Why High-Temperature Injection Molding Matters
Conventional plastics often fail under continuous heat, mechanical stress, or chemical exposure. High-temperature polymers are engineered to maintain dimensional stability and mechanical integrity where standard materials degrade.
- Stable mechanical performance under extreme heat
- Excellent resistance to chemicals and fatigue
- Reliable precision for functional assemblies
What Is High-Temperature Injection Molding?
High-temperature injection molding is a precision manufacturing process for polymers with heat resistance above 150°C, such as PEEK, PEI, PPSU, and LCP. By precisely controlling processing conditions, optimal crystallinity and dimensional accuracy are achieved.
High-Temperature Materials We Process
Our manufacturing capability covers a wide range of high-performance thermoplastics, selected to meet specific mechanical, thermal, and chemical requirements.
- PEEK
