Key Features of HDC Series Double Injection Molding Machines
Patented Safety Rotary Table Technology
ー Patent M391464
Our patented rotary table (Patent No. M391464) ensures stable operation, accurate positioning, and triple safety protection—mechanical, electrical, and hydraulic—guaranteeing the table will never fall during operation.
External Gearing for Rapidity and Accuracy
An advanced external gearing system enhances both rotation speed and positioning precision, improving overall production efficiency and process control.
Optional Servo Motor-Drive Rotation
For enhanced energy efficiency and precision, a servo motor-driven rotation system is available. This provides smoother operation and reduced energy consumption.
Optional Interchangeable Turntable and Shaft Design
Offers dual-configuration flexibility: rotary table for general two-color molding, or a central 180° rotating shaft for more compact applications like toothbrushes or handles.
Optional Extra T-Type/L-Type Injection
The HDC Series supports optional T-type or L-type auxiliary injection units to enable triple-material molding or more complex product structures.
