TPU plastic parts supplier

We are a specialized manufacturer and supplier of high-performance custom Thermoplastic Polyurethane (TPU) plastic parts and components. We engineer and produce durable components that excel in environments requiring exceptional abrasion resistance, elasticity, and toughness. As your direct manufacturing partner, we control the entire process—from material selection and precision tooling to injection molding and value-added assembly—delivering elastomeric solutions that bridge the gap between hard plastics and soft rubbers.

Our Service: Engineered TPU Components & Integrated Assemblies

We supply and manufacture the critical, resilient plastic parts that endure wear, flex, and impact. Our core offering is producing custom TPU components where mechanical performance under stress is key. We extend significant value through secondary services such as CNC machining, trimming, bonding, and assembly, providing you with ready-to-integrate sub-assemblies that reduce complexity.

Custom Design for TPU's Unique Elastic & Mechanical Properties

Designing for TPU requires a focus on its hyper-elastic recovery, strength, and processing characteristics. We engineer parts to maximize longevity and function:

Ribs, Gussets & Wall Thickness: Strategically applied to support loads and maintain shape in flexible sections without inhibiting the part's ability to bend or compress. Consistent wall thickness is prioritized for uniform cooling and performance.

Sealing Lips, Gaskets & Diaphragms: Precisely engineered cross-sections to utilize TPU's excellent compression set and recovery for reliable, long-term static or dynamic sealing.

Wear Surfaces & High-Abrasion Areas: A core specialty. We design components like cable jackets, rollers, and scraper blades to maximize material thickness in contact zones, directly leveraging TPU's superior wear resistance.

Living Hinges & High-Flex Zones: Designed with optimal radius and thickness to withstand millions of flex cycles without failure, capitalizing on TPU's outstanding fatigue endurance.

Overmolding & 2-Shot Bonding Interfaces: We expertly design mechanical interlocks (undercuts, holes, textures) on rigid substrates (PC, ABS, Nylon) to ensure a permanent, high-strength bond with the TPU overmold for grips, seals, or protective bumpers.

TPU Material Science: Selecting the Right Polyurethane Grade

TPU properties vary significantly based on its polymer backbone (polyester, polyether, polycaprolactone). We guide you to the optimal formulation:

Polyester-based TPU: Offers superior abrasion resistance, mechanical strength, and resistance to oils, fuels, and solvents. Ideal for industrial rollers, drive belts, hydraulic seals, and athletic equipment.

Polyether-based TPU: Provides outstanding low-temperature flexibility, hydrolysis resistance (against water/moisture), and microbial resistance. Preferred for underwater cables, marine components, and medical tubing.

Key Performance Grades & Applications:

High-Transparency & Medical Grades: Offer clarity and compliance with USP Class VI / ISO 10993 for medical tubing, fluid guides, and transparent protective covers.

FDA-Compliant & Food-Grade: Suitable for components in contact with food and beverages.

Shore Hardness Range: We supply and process a vast spectrum, from soft Shore 60A (gel-like, flexible) to rigid Shore 75D (near-hard plastic), tailoring the feel and function to your exact needs.

Reinforced & Specialty Grades: Glass-filled for added stiffness, or colors matched to specific Pantone references.

Key TPU Properties Driving Selection:

Exceptional Abrasion & Tear Resistance: Arguably the best among thermoplastic elastomers, perfect for parts in constant frictional contact.

High Elasticity & Load-Bearing Capacity: Can be stretched and compressed repeatedly while returning to its original shape and supporting substantial weight.

Broad Temperature Range Performance: Maintains flexibility at low temperatures and stability at elevated temperatures compared to many elastomers.

Transparency & Sterilizability: Certain grades allow for clear parts that can withstand sterilization methods (Gamma, ETO).

The Precision TPU Injection Molding Process

Processing TPU demands specific expertise to manage its moisture sensitivity and unique melt viscosity. Our controlled process ensures optimal part quality.

Critical Pre-Process: Drying. TPU is highly hygroscopic. Mandatory, rigorous drying in dehumidifying hoppers is essential to prevent moisture-induced defects like bubbles, splay, or molecular degradation which severely weaken the part.

Process Specifics: We utilize precise, controlled barrel temperatures to properly melt the material without thermal degradation. Moderate injection speeds and pressures are used to manage the melt's viscosity and prevent excessive shear heating. Accurate mold temperature control is vital for achieving consistent cycle times, surface finish, and dimensional stability.

Key Advantages of Our TPU Molding Expertise:

Consistent Mechanical Property Realization: Proper drying and thermal control ensure every part achieves the intended tensile strength, elongation, and abrasion resistance.

High-Quality Surface Finish: Our process minimizes flow lines and surface defects, producing parts with a smooth, consistent finish straight from the mold.

Effective Bonding in Overmolding: We master the thermal and chemical interface requirements to create robust, inseparable bonds between TPU and rigid substrates in multi-shot molding.

Managing Complexity: TPU's flow characteristics allow us to mold complex geometries, thin-walled features, and intricate details reliably.
