Capabilities

We design and produce precision molds in-house using advanced machinery, including Makino, Sodick, Mazak, and FANUC. We use high-quality steels such as S136, NAK80, and H13, achieving up to ±0.01 mm accuracy, molds up to 2 meters in size, and a lifespan of 500,000 cycles.

Before making molds, we also help our customers create prototypes using SLS, SLA, FDM, and CNC machining, so we can verify and refine the design to ensure it’s ready for production. Our molds enable us to deliver reliable manufacturing for medical devices, fitness equipment, and household electronics.
Mold design and making
Plastic injection molding
Our modern injection molding workshop houses 48 advanced machines, including two dual-color units (250T and 350T) for multi-material and two-color products. Brands include Haitian, Yizumi, and FANUC, all equipped with robotic arms for automation. Precision reaches ±0.02 mm, with strict in-process inspections, full traceability, and environmentally responsible recycling of defective parts.
Silicone molding
We EPPOSUN offers comprehensive silicone molding services, including LSR molding, silicone dispensing, and compression molding. Our workshop is equipped with 15 hydraulic presses, 2 dual-color silicone machines, an automated coating line, and a silk-screen printing line. These facilities enable precise, high-quality production of silicone parts for medical, consumer, and industrial applications, with consistent quality and reliable performance.

Our silicone production covers a wide range of applications, including electronic protective housings, keyboard mats, keycaps, medical silicone products, kitchen utensils, sports and protective items, baby & child tableware, and pet products. This diversity allows us to serve multiple industries with tailored solutions.
Metal manufacturing
We provide full-service metal manufacturing, including stamping, forging, die casting, and CNC machining. Our facility features 36 stamping presses, 3 forging machines, 7 high-pressure die casting units, and 26 CNC centers (including 6 five-axis machines), producing precise, high-quality components.

Every batch undergoes strict quality control with full traceability, allowing us to deliver reliable metal parts for automotive, electronics, industrial equipment, and other applications.
Secondary processing center
Our secondary processing center provides UV coating, printing, electroplating, laser engraving, and other post-production operations. We assist customers with final assembly and testing, including airtightness, battery aging, wear resistance, drop impact, and tensile strength tests. Every process follows strict quality control with full traceability, ensuring high-quality, aesthetically refined, and fully customized products.
