Product Description:
High-precision 2K enclosure engineered for ruggedized handheld devices requiring integrated shock absorption and ergonomic grip. The tooling utilizes a sophisticated two-shot process to bond a structural PC-ABS frame with a soft-touch TPU/TPE skin, eliminating the need for secondary assembly and adhesive bonding. Designed with complex internal lifters to accommodate deep battery compartments and precise shut-off geometry to prevent flash at the sharp material transitions. Built to meet Tier-1 standards for structural rigidity, chemical resistance, and repeatable snap-fit assembly in high-volume production.
Product Overview
This product is a premium sample of our two-color injection molding (2K molding)capabilities. Designed for high-precision handheld electronic devices, this enclosure combines structural integrity with an ergonomic, multi-material finish. We specialize in providing end-to-end solutions from mold design to mass production for complex, dual-material plastic parts.
Key Features
- Advanced Two-Color Injection Technology: Features a seamless integration of two different colors/materials (e.g., Rigid ABS + Soft TPE) in a single molding process, ensuring high durability and a premium aesthetic without the need for secondary painting.
- Ergonomic & Industrial Design: The side-grip textures are precision-molded to provide a non-slip, comfortable handling experience, ideal for handheld tools and measurement instruments.
- Integrated Functional Compartments: Includes a built-in dual AAA battery compartment with high-precision contact points, a dedicated LCD screen window, and pre-engineered sensor apertures.
- High-Precision Fit: Our molds are engineered to extremely tight tolerances, ensuring a perfect snap-fit between the front and back covers for superior dust and moisture protection.
- Fully Customizable: We offer full OEM/ODM services. You can customize the material (ABS, PC, Nylon, TPE), colors (Pantone matched), surface textures, and brand logo engraving.
