China Custom TPE and ABS Double Color Injection Molding & Overmolding Supplier, Manufacturers
Product Description
Product Overview
Shenzhen Sunmy Hardware Co., Ltd. specializes in high-precision Custom TPE and ABS Double Color Injection Molding, Overmolding, and Insert Molding. Designed for industries requiring ergonomic and highly durable components, our multi-material molding solutions seamlessly combine the structural rigidity of engineering plastics (like ABS) with the soft, tactile grip of elastomers (like TPE). This process is highly ideal for power tool housings, household appliances, electronic enclosures, and automotive components, providing superior functionality and aesthetic appeal.
Process & Manufacturing Insights
Our advanced Plastic Injection Molding capabilities allow for complex, multi-shot processes. In double-color molding and overmolding, a rigid plastic substrate is molded first. A softer elastomer is then precisely injected over or around the substrate to form a permanent chemical or mechanical bond. This eliminates the need for secondary assembly steps, ensuring a highly durable, water-resistant, and aesthetically pleasing finish. Supported by comprehensive in-house tooling capabilities, we utilize premium mold bases and advanced engineering design software to guarantee flawless precision and consistency across every production batch.

Main Features & Advantages
Technical FAQ
A: We support flexible MOQs tailored to your specific project phases, ranging from low-volume prototyping to high-volume mass production. Contact us to discuss your requirements.
A: We implement rigorous quality control protocols, including material compatibility testing, precise temperature and pressure control during injection, and comprehensive post-production dimensional inspections to ensure perfect adhesion and zero defects.
A: Standard mold fabrication generally takes 25 to 35 days, depending on design complexity. Once the mold is approved by the client, mass production lead times are highly efficient and scheduled strictly according to your order volume.
A: Common combinations include rigid substrates like ABS, PC, or Nylon bonded with soft elastomers such as TPE or TPR. Chemical compatibility between materials is key to achieving optimal bond strength without adhesives.
A: We accept STEP, IGES, X_T, DWG, and SolidWorks native formats. Our engineering team conducts comprehensive Design for Manufacturability (DFM) analysis on all submitted files.
