5 Key Application Fields of TPU Injection Molding

Flexible gaskets, bushings, and anti-vibration pads made via TPU plastic injection molding help vehicles stay quiet and resilient.

Biocompatible, sterilizable parts like tubes, connectors, and sensor housings made in cleanroom environments.

Smartwatch straps, earbuds, and flexible enclosures benefit from TPU molding‘s softness, flexibility, and sweat resistance.

Drop-resistant cases, cables, and flexible covers use TPU overmolding to merge tactile feel with structural performance.

Grip handles, cable sheaths, and shock mounts — all relying on rugged, chemical-resistant TPU material for injection molding.

TPU Injection Molding-FAQ S
It’s ideal for flexible, tough parts like wearable bands, soft grips, and impact-resistant covers where both elasticity and strength are needed.
Absolutely. TPU resists abrasion, oils, and chemicals, making it perfect for demanding environments like automotive and factory tools.
Yes, TPU bonds very well with PC, ABS, and nylon. It’s commonly used in overmolding to create soft-touch or protective layers.
We do. Whether you need 100 prototypes or 10,000+ parts, we adjust our workflow to your project stage and volume.
We combine precise tooling, stable temperature control, and full QC at every step to deliver consistent parts every run.
TPU is a type of TPE but with higher mechanical strength and wear resistance. It’s tougher, more elastic, and holds up better in harsh conditions. If your part needs better durability or chemical resistance, go with TPU. For softer, lower-stress parts, TPE might be enough.
Most TPU injection molding grades run best between 200°C to 250°C, depending on the brand and hardness. But it’s not just about melt temp — mold temperature control (30°C to 65°C) is key for surface finish, part strength, and preventing defects like bubbles or short shots.
Typical TPU injection molding wall thickness ranges from 0.8mm to 3mm, depending on part size, flow length, and flexibility needs. Too thin, and you risk warping or incomplete fills. Too thick, and you may get sink marks or longer cooling times. We help balance design and moldability.
Yes, TPU can absolutely be injection molded. It’s one of the most effective ways to shape thermoplastic polyurethane into complex, high-performance parts. Its excellent flowability and quick cooling behavior make it ideal for creating flexible yet tough components in large volumes.
TPE refers to all thermoplastic elastomers. TPR is a SEBS-based TPE, soft but not oil-resistant. TPU is the most abrasion-resistant TPE, ideal for industrial parts. LSR is liquid silicone rubber, heat-resistant and used in medical, baby, and food-grade applications.
