The Servo Bi-color Injection Molding Machine integrates dual-injection units into a single system, allowing for simultaneous or sequential molding of two distinct plastic colors or materials. This equipment is the optimal solution for complex, high-aesthetic, or functional automotive, consumer electronics, and packaging components.
We provide fully servo-driven bi-color injection molding machines with stable performance, OEM/ODM customization, and complete technical support for global industrial buyers.
Key Technical Advantages
Precision Servo Control: Integrated closed-loop servo system reduces energy consumption by 30–50% compared to traditional hydraulic systems.
Versatile Injection Logic: Independent dual-barrel design enables both parallel and serial injection, facilitating high-complexity part geometry and clear color separation.
Advanced Durability: All critical mechanical components-including guide rods and screw assemblies-undergo high-frequency quenching and anti-corrosion treatments.
High-Accuracy Positioning: The servo-driven rotary table offers a repetition accuracy of ±0.05mm.
