High-Precision 2-Cavity Double-Shot (2K) Injection Mold | Custom Two-Color Plastic Tooling for Multi-Material Components


Product Overview

This is a sophisticated 2-cavity double-shot (2K) injection mold, designed for high-efficiency production of multi-material plastic parts. This tooling technology allows two different colors or types of plastic (e.g., ABS + TPE) to be molded into a single component within one machine cycle, ensuring perfect bonding and structural integrity.
At JST Mold, we are experts in complex 2K / Two-Shot molding. This 2-cavity mold features high-precision sealing surfaces to prevent color bleeding and advanced mechanical movements to handle material transitions. It is an ideal solution for automotive buttons, ergonomic handles, and high-end consumer electronic housings that require both aesthetics and functional performance.


Key Features

  • Advanced 2K / Double-Shot Technology:Enables the integration of two materials/colors in one shot, eliminating the need for secondary assembly and providing a premium, seamless finish.
  • 2-Cavity High Efficiency:Optimized 2-cavity layout balances production speed with extreme dimensional consistency across both parts.
  • Precision Sealing Design:Engineered with micron-level tolerances on sealing faces to ensure zero flash and clear-cut color separation lines.
  • Complex Core/Cavity Movement:Designed for compatibility with rotary-table or transfer-type 2K injection machines, featuring robust mechanisms for long-term reliable operation.
  • Optimized Hot Runner System:Equipped with a balanced hot runner manifold to ensure uniform plastic flow and temperature control for both materials.
