2K Injection Mold

Dual-Shot Molding for Function & Aesthetics

Two-color (2K) injection molding combines two resins in a single mold to produce parts with different textures, colors, or material properties. It's widely used in automotive, consumer electronics, and home appliances, combining functional layering with visual design effects.

Two-color injection molding (also known as two-shot molding) is a process in which two different plastic materials or colors are injected sequentially or simultaneously into a mold to form a single finished part. This eliminates the need for secondary assembly or bonding.

MID Mould specializes in the design and manufacture of precision two-shot molds for:

Rotary platen injection molding machines
Core-retraction or indexing systems
Transfer-type injection molding units

We support a variety of two-shot molding combinations, such as:

Soft + hard materials: PC + TPE, ABS + TPU
Transparent + opaque materials: PMMA + ABS for optical clarity
Two-shot molding: for product branding or user interface design

Two-shot molds require high-precision alignment and tight tolerances between the two mold cavities or rotating cores. Our engineering team ensures:

Smooth, flash-free material interfaces
Strong resin-to-resin bonding
Perfect color registration and part ejection

Applications include:

Automotive components: knobs, buttons, interior trim
Consumer electronics: power buttons, smartwatch frames
Home appliances: control panels, transparent windows
Medical products: two-color housings, ergonomic tools

Our two-color molds operate efficiently and with high repeatability, providing a reliable solution for innovative designs and multifunctional integration.
