TPR Molding

Modern Plastic Molding solutions have become more dynamic and sophisticated thanks to the advancement of TPR Molding techniques. By injecting Thermoplastic Rubber into precision molds, manufacturers can produce soft, flexible parts that still retain structural integrity. This process is especially valuable in markets that demand ergonomic functionality — such as wearable electronics, children’s products, and medical devices. Through precise mold design and optimal material flow, TPR Molding allows for seamless shaping of intricate components that are resistant to deformation and chemicals.Moreover, as consumer expectations rise for better tactile response and stylish design, this molding technology empowers producers to meet complex aesthetic and functional goals in one streamlined process. Emerging technologies have further enhanced molding speed and repeatability, reducing waste and improving part uniformity. In industries such as home automation or sports gear, manufacturers benefit from the adaptability of rubber-integrated designs that complement both casual and professional applications. These molded products also maintain high dimensional accuracy even in high-volume production, reducing the need for post-processing or corrections.

Air / Pneumatic Tools Handle / Grip
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.

TPR Overmolding

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.
