Custom Two-Shot Injection Mold - Overmolding Process

Product Description

CUSTOM TWO-SHOT (OVERMOLDING) INJECTION MOLD Advanced two-shot injection molding solution designed for integrating multiple materials into a single, complex component. This process utilizes sequential injection to bond dissimilar plastics (e.g., rigid substrate + soft-touch elastomer), eliminating the need for secondary assembly and enhancing part performance. Ideal for functional components requiring improved grip, sealing, insulation, or aesthetic contrast. KEY SPECIFICATIONS • Process Type: Two-Shot / Overmolding Injection Molding • Typical Material Combination: ABS/PC (Hard) + TPE/TPU (Soft) - Customizable per application • Mold Material: H13 (DIN 1.2344/1.2366) Hot Work Steel - Pre-hardened for thermal stability • Mold Base: Standard or Custom (LKM, HASCO, DME compatible) • Cavity Configuration: Single Cavity (Optimized for precise material interface control) • Cooling System: Independent baffle cooling for each shot to ensure thermal balance • Ejection System: Precision ejector pins & plates designed for dual-material release • Tooling Life: 500,000 - 1,000,000 shots (Dependent on material compatibility and operating parameters) CORE ADVANTAGES • Material Synergy: Creates a permanent molecular bond between hard and soft plastics in one cycle. • Enhanced Functionality: Adds soft-touch grips, waterproof seals, vibration dampening, or electrical insulation. • Design Freedom: Enables complex geometries, living hinges, and multi-color aesthetics impossible with single-shot molding. • Cost Efficiency: Reduces labor, assembly time, and inventory by consolidating multiple parts into one. • Durability: H13 steel construction ensures longevity under high-temperature, high-pressure molding conditions. TYPICAL APPLICATIONS • Industrial Components: Ergonomic handles, control knobs, sealed connectors, vibration isolators • Consumer Goods: Toothbrush handles, power tool grips, appliance buttons, wearable device straps • Automotive Parts: Gear shift knobs, interior trim, soft-touch dashboard elements • Electronics: Cable grommets, waterproof enclosures, keypad membranes ENGINEERING SUPPORT Our team provides comprehensive DFM (Design for Manufacturing) analysis, focusing on gate location, material compatibility, and shrinkage compensation for dual materials. Mold flow simulation ensures optimal filling and bonding. Full technical documentation (2D/3D drawings, BOM, operational guidelines) provided. 12-month warranty on mold base; lifetime technical support available. Full view of the two-shot mold assembly, highlighting the hot nozzle system and core/cavity structure.
