TPE injection molding service

We are a specialized manufacturer serving as your single-source partner for both custom molded plastic containers and engineered plastic housings. We design, engineer, and produce functional storage solutions and protective enclosures, providing a seamless bridge from concept to assembled component. As your dedicated manufacturing partner, we offer integrated expertise—from material science and industrial design to precision molding, finishing, and assembly—delivering ready-to-use solutions that simplify your supply chain.

Our Service: Engineered TPE Components & Multi-Material Assemblies

We manufacture the critical flexible plastic parts that provide sealing, cushioning, grip, and aesthetic appeal. Our core competency lies in producing custom TPE components, as well as sophisticated overmolded and 2-shot molded parts where TPE is securely bonded to a rigid substrate (like PP, ABS, or PC). We further provide assembly services, delivering integrated components that simplify your supply chain.

Custom Design for Flexibility & Bonding Performance

Designing for TPE requires a focus on elastomeric behavior, bond interfaces, and flow characteristics. We engineer each part for optimal functionality:

Sealing Lips & Gaskets: Precisely designed cross-sections (like bulb seals or flat flanges) to ensure consistent compression and effective sealing against moisture, dust, or air.

Grips & Handle Sections: Ergonomically contoured with textured surfaces for slip resistance, often designed as overmolds onto rigid handles for comfort and safety.

Living Hinges & Flexible Diaphragms: Utilizing TPE's excellent flex fatigue resistance for parts requiring repeated motion without failure.

Overmolding Bonding Interface: The most critical design aspect. We engineer the rigid substrate with undercuts, through-holes, or a textured surface to create a strong mechanical interlock for the TPE, ensuring a permanent bond.

Wall Thickness & Flow: Managed to ensure even filling and prevent sink marks in softer grades, with generous radii to facilitate flow and reduce stress concentrations.

TPE Material Science: Selecting the Right Elastomer for the Task

TPE is a vast family of materials. We partner with compounders to select or formulate the perfect grade for your application’s feel, performance, and compatibility.

TPS/TPE-S (Styrenic Block Copolymers): The most common, cost-effective TPEs. Offer a wide hardness range (Shore OO to A) for consumer product grips, soft-touch overmolding, bottle droppers, and seals.

TPV (Thermoplastic Vulcanizates): Provide superior heat, oil, and weather resistance, closely mimicking EPDM rubber. Ideal for automotive seals, under-hood components, and industrial gaskets.

TPU (Thermoplastic Polyurethane): Offers outstanding abrasion resistance, toughness, and elasticity. Used for protective cases, rollers, wheels, and medical tubing.

TPE-O/TPO (Polyolefin-based): Known for excellent UV resistance and lower density. Primarily used in automotive interior trim and exterior bumpers.

Bondable Grades: Specifically formulated for chemical/adhesive bonding to engineering thermoplastics (e.g., TPE bonded to ABS, PC, PA) during overmolding, a key area of our expertise.

Key TPE Properties & Applications:

Rubber-Like Elasticity & Softness: Replaces traditional rubber with easier processing and recyclability for seals, gaskets, and cushioned components.

Enhanced Grip & Ergonomics: Improves user experience and safety in tools, electronics, medical devices, and automotive interiors.

Excellent Sealability & Compression Set: Provides reliable, long-term sealing performance in dynamic or static applications.

Overmolding Capability: Creates permanent, multi-material parts in a single or two-shot process, eliminating the need for adhesives or separate assembly.

The Precision TPE Injection Molding & Overmolding Process

Molding TPE successfully, especially in overmolding, requires specialized knowledge of flow, temperature windows, and adhesion mechanisms.

Process Specifics for TPE: We use lower melt temperatures and higher injection speeds compared to rigid plastics to fill molds quickly, leveraging TPE's shear-sensitive nature. Precise mold temperature control is critical to achieve a smooth surface finish, prevent flash, and optimize cycle time.

Overmolding/2-Shot Molding Process: This is our advanced specialty. It involves molding the rigid substrate first, then either transferring it to a second cavity or using a rotary mold to inject TPE directly onto it. The key is controlling the temperature of the pre-formed substrate to ensure a molecular-level bond with the TPE melt.

Key Advantages of Our TPE Molding Service:

Strong, Consistent Overmold Bonding: Our process expertise ensures a reliable bond between the TPE and substrate, eliminating delamination in the field.

Aesthetic & Tactile Quality: We produce parts with consistent, defect-free surfaces and a precise, desirable soft-touch feel.

Design & Function Integration: We combine rigid structural elements with flexible features in a single, integrated component, reducing part count and assembly cost.

Material & Process Efficiency: TPEs are fully recyclable sprues/runners (unlike thermoset rubber), and our efficient processes minimize waste.

Why Partner with Us for TPE Components?

Our differentiation lies in our focused expertise in multi-material molding and elastomer processing. We provide essential Design for Manufacturability (DFM) analysis focused on bond line design, material compatibility, and gate placement for soft materials. We manage the entire process, from selecting the right TPE compound to designing molds for efficient overmolding, ensuring your soft-touch or sealing components perform reliably.

Choose us for your TPE parts when you need to integrate flexibility, sealing, or an enhanced user touchpoint into your product. We deliver engineered elastomeric solutions that bridge the gap between hard plastic and soft rubber.

We are plastic mold maker and can provide custom mold service, we can make injection molds, blow molds, rotational molds and die-casting molds.

For custom injection molds, we can provide professional custom injection molding services. Usually Plastic injection mold manufacturing Molding are manufactured using injection molding technology. The mold materials for injection molds can be chosen from P20, 718, S136, H13 and so on. The mold material reflects the mold life and product material requirements.
