繁體中文Combining flexibility with resilience, Thermoplastic Rubber has become a preferred material in plastic engineering for dynamic applications. At the forefront of this evolution is , a seasoned expert in molding technologies since 1978. The company utilizes specialized techniques to process elastomeric polymers into precise, functional components suited for rugged usage. Their vertically integrated manufacturing system simplifies the transition from concept sketches to mass production, optimizing cycle times and quality control. This approach is particularly valued by industries requiring shock-absorbent, heat-resistant parts — such as sporting goods, industrial tools, and consumer electronics.Modern consumers increasingly demand products that are both functional and adaptable, making flexible plastics essential in many sectors. By refining its design and tooling methods, the team ensures every shape and dimension meets end-user expectations and long-term usage requirements.
Thermoplastic Rubber
Product Specifications: Aluminum/Die Casting + TPR/TPE
Product Description:
Air/Pneumatic tools Housing / Case (TPR Overmolding)
TPR Overmolding for Enhanced Grip & Shock Absorption Whether using powder-coated or liquid-painted metal housings, TPR (Thermoplastic Rubber) overmolding is an ideal solution to enhance grip comfort and reduce vibration. This improves ergonomic performance and minimizes user hand fatigue.
Unlike manual assembly, TPR overmolding enables high-speed, large-volume production while reducing the risk of slipping, cracking, or detachment. It’s especially suitable for plastic injection molding applications that demand both performance and user comfort.
Key benefits of TPR include:
Excellent abrasion resistance and deformation stability Strong electrical insulation and heat resistance Resistance to grease and harsh chemicals At Sung I Industrial, we specialize in mold development, OEM/ODM, and custom manufacturing. With full vertical integration, we work with advanced engineering plastics and sustainable materials to deliver reliable, production-ready solutions.

Overmolding Technology｜Enhanced Grip & Brand Identity Through Multi-Material Integration
At Sung I Industrial, we specialize in plastic injection molding and mold development, offering fully custom manufacturing solutions that balance both functionality and aesthetics. Our advanced overmolding technology allows materials like TPR and TPE to be molded directly over metal or plastic substrates, enhancing grip, anti-slip performance, and shock absorption.
Even for metal components with a pre-applied paint or coating finish, Sung I ensures that the overmolding process will not scratch or damage the surface—maintaining a flawless appearance. We can also integrate rigid materials like PP to increase structural strength while offering a dual-layer surface design that adds visual diversity and improves product recognition. This makes it an ideal solution for ergonomically designed products such as hand tools, sporting goods, and automotive components.
With full OEM/ODM support and a vertically integrated workflow, Sung I manages every step from design, material selection, and mold fabrication to injection molding, post-processing, and final packaging—delivering high-quality, scalable overmolding solutions for today’s performance-driven markets.
