Custom TPU Molding Solution
Zhongren specializes in custom TPU injection molding, delivering high-performance molded TPU parts for demanding applications. With years of experience and advanced equipment, we support complex geometries, overmolding, and tight-tolerance requirements. TPU molding is ideal for flexible yet durable components, combining the processability of thermoplastics with the performance of rubber.
How Are Thermoplastic Polyurethane (TPU) Parts Manufactured?
We use several advanced TPU injection molding techniques to produce high-performance molded TPU parts tailored to your application needs:
- Thermoplastic Polyurethane Injection Molding
- TPU Overmolding
- Insert Molding with TPU
- TPU Extrusion Molding
Key process factors include precise material selection, mold design optimization, and tight temperature and pressure control to ensure proper flow, bonding, and long-term part durability.

- Higher material cost than some standard plastics
FAQ with TPU Injection Molding
Can TPU be overmolded?
Yes, TPU is commonly overmolded onto plastic or metal substrates for added grip, cushioning, or sealing.
Is TPU safe for medical or food use?
Yes. We offer medical-grade and FDA-compliant TPU materials on request.
Is TPU injection molding recyclable?
Yes. Unlike thermoset rubbers, TPU material injection molding supports full recyclability.
How does TPU compare to rubber?
TPU offers similar flexibility to rubber but with better wear resistance, clarity, and chemical resistance. It also processes faster and more cleanly via injection TPU techniques.
