HMD 170-DM3 Hybrid Three-Color Injection Molding Machine
Three independent injection units · Dual linear-guide injection unit · One-shot three-color molding
HMD 170-DM3 is a hybrid three-color injection molding machine on the 1700 kN platform with three independent synchronized injection units. It can fire three colors or materials synchronously or in intervals within a single clamping cycle for complex gradient and multi-color effects, and remains versatile for single-color production.

Core Advantages
One-Shot Three-Color Molding
Three independent injection units fire synchronously or in intervals to mold three-color products in one shot, greatly shortening cycle time.
Color-Gradient Injection Process
Simultaneous or interval injection during molding produces gradient effects, giving products richer color expression.
Multi-Purpose Versatility
The machine can also produce single-color or two-color products, providing versatile capability and all-round service.
Optimized Screw and Barrel Assembly
Optimized screw and barrel assembly delivers stronger plasticizing capability and better plasticizing performance, meeting a variety of special product needs.
Dual Linear-Guide Injection Unit
The dual linear-guide injection-unit structure keeps all three injection units running stably with accurate positioning.
