繁體中文Two Color Injection Molding
Plastic molding has evolved into a sophisticated field where customization, functionality, and aesthetics must coexist seamlessly. Among the most refined techniques in the industry, Two Color Injection Molding provides a unique advantage — allowing two different materials or colors to be injected into a single mold in one cycle. This technology is ideal for producing complex plastic components with both functional and visual layers, such as dual-tone handles, dials, or ergonomic grips. As consumer expectations rise for products that blend usability and design, this advanced method proves invaluable. SUNG I INDUSTRY CORP. integrates this approach into its vertically aligned operations, optimizing every stage from mold development to final assembly. With over four decades of specialized experience, the company maintains full control over the entire process, ensuring not only precision and consistency but also accelerated lead times. Custom injection molding solutions at SUNG I are tailored for diverse demands — be it for automotive interiors, home appliances, or handheld electronics. Each project begins with in-depth CAD evaluations and material selection strategies, advancing through mold simulation, tooling, and efficient mass production.

Product Description:
Bicycle & Tool Handle / Grip (Dual Color Plastic Injection Molding)
Dual color injection molding, also known as two-color overmolding, is a high-efficiency plastic injection molding process that combines two different materials or colors into a single part using one mold and one machine. This process is ideal for products requiring both functional performance and visual appeal—such as bicycle grips, power tool handles, and lifestyle accessories. Dual color molding is ideal for mass production as it helps to reduce cycle time by 25–40%, while maintaining high consistency in product quality.
Compared to traditional assembly methods, this overmolding approach reduces the need for manual labor and secondary processes, minimizing assembly errors and enhancing production efficiency. At Sung I Plastic Inc., we specialize in custom manufacturing and offer one-stop solutions from insert molding to fully integrated OEM / ODM production.
Our experience in developing molds for complex geometries and multi-material combinations allows us to deliver durable, functional, and visually appealing components. Whether you're launching a new consumer product or upgrading an existing line, two-color injection molding offers a cost-effective and scalable solution for industries that value both performance and design.
In a global market that demands reliable suppliers for high-end plastic components, being a dedicated manufacturer isn’t enough — it's about offering versatility, engineering excellence, and eco-conscious production. Taiwan’s role in this ecosystem has steadily risen, and SUNG I INDUSTRY CORP. stands at the forefront by integrating sustainable practices such as recycled resin use and energy-saving manufacturing. Their commitment goes beyond delivering parts — they co-develop new products with clients, often acting as both a supplier and an engineering consultant.
From industrial tools to sporting goods, their output meets international compliance standards like RoHS and FDA, ensuring global reach. As exporters rooted in Taiwan’s reputation for quality, they position themselves not just as the best in local manufacturing but as an ideal partner for forward-thinking brands. Two Color Injection Molding isn’t simply a trend — it’s a strategic solution, and when combined with customized development paths, it becomes a powerful product differentiator. Businesses that seek to lead in function, design, and sustainability choose partners like SUNG I for complete, integrated plastic solutions.

TPE Plastic Injection Molding Products
TPE Thermoplastic Elastomer Injection Molding – Flexible and Efficient Rubber Alternative
Thermoplastic Elastomers (TPE) combine the elasticity of rubber with the efficient process ability of plastics. Unlike traditional rubber molding, TPE injection molding features shorter cycle times and allows for runner material recycling, making it an ideal solution for cost-effective, high-volume production. This process enhances manufacturing efficiency without compromising performance or quality.
TPE plastic injection molding is widely used in applications that require soft-touch and flexibility, such as tool grips, protective covers, medical components, automotive parts, and anti-slip mats. Its excellent impact resistance and skin-friendly texture make it a popular choice for ergonomic and user-interactive designs. At Sung I, we specialize in custom injection molding services and product development for various industries. Our team works closely with clients from concept to production, offering solutions that include material selection, mold design, and surface treatment. We also support sustainable manufacturing with eco-friendly materials, and can provide documentation for RoHS, REACH, FDA, and CE compliance upon request.
With decades of experience in plastic injection molding, Sung I delivers integrated solutions tailored to your product's unique specifications. Whether you're producing small batches or scaling up to mass production, TPE injection molding offers durability, flexibility, and aesthetic versatility for a wide range of industries.
