Erye Offer TPU Injection Molding Service Specific to Your Needs!

Thermoplastic polyurethane (TPU) injection molding is perfect for creating parts that need to be tough, flexible, and resistant to wear. Whether it's a soft and flexible material or a more rigid, durable one, TPU offers the best of both worlds—high elasticity and impressive impact resistance. TPU molding product has excellent resistance to oils, chemicals, and abrasion, making it ideal for a wide range of applications. We specialize in delivering precisely molded TPU parts that meet your specific needs, from prototypes to large-scale production runs.

TPU Injection Molding Design Tips

When designing TPU injection molded parts, it's essential to consider key factors that affect performance and manufacturability. Here are some important design tips to keep in mind.

Item	Description
Wall Thickness	Keep wall thickness consistent, ideally 2-4mm, to prevent warping and ensure even cooling.
Draft Angles	Use a draft angle of 1-3° to make part ejection easier and reduce stress during removal.
Radii and Fillets	Incorporate smooth radii and fillets at corners to prevent stress points and improve durability.
Undercuts	Minimize undercuts to reduce tooling complexity; use removable inserts or secondary operations if necessary.
Thin-to-Thick Transitions	Design gradual transitions between thick and thin sections to prevent material strain and ensure uniform flow.
Gate Location and Design	Place gates strategically in areas that promote uniform filling, and consider using multiple gates for larger parts.

Advantages of TPU Molding

Customizable Hardness

TPU offers a wide range of hardness levels (from Shore A 70 to Shore D 50), providing versatility to

Superior Abrasion Resistance

TPU demonstrates excellent resistance to wear and tear, with some formulations providing abrasion resistance up to 3 times better than rubber, making it ideal for heavy-duty applications.

Durability in Harsh Conditions

With an impact resistance that can withstand temperatures from -40°C to +125°C, TPU is ideal for products exposed to extreme conditions without losing performance.

Enhanced Dimensional Stability

TPU maintains excellent dimensional stability, with low shrinkage rates (typically 0.2% to 0.5%), ensuring precise and consistent part quality during injection molding.

High Flexibility and Elasticity

TPU has a high elongation at break (up to 600%), allowing it to maintain flexibility and elasticity even after repeated stretching or bending.
