DETAIL

Suitable for the production of rubber and silicone products that require stricter molding conditions and higher quality.


Precision manufacturing

Austrian Bmr industrial-grade controller, ensuring stable execution of injection material closed-loop control, enabling flexible and precise control of pressure, speed, and temperature to enhance product quality.


Hydraulic closed-loop feeding injection control

Consistent rubber dimensions and weight, suitable for the production of precise rubber products, addressing the stability issues found in conventional injection machines.

FIFO injection unit
The advanced first-in, first-out injection unit minimizes the residence time of rubber materials in the material storage tube, ensuring the uniformity of rubber material curing.



 


Energy-saving servo hydraulic system

Servo motors adjust their rotational speed based on the required flow rate, reducing energy wastage and potentially decreasing energy consumption by 35% to 50%.


Stable temperature control

The Japanese-made OMRON PID temperature controller paired with a three-phase SSR for multi-stage temperature control.

 
Diversified mold opening systems

The option to choose between a standard mold opening system or a customized dedicated mold release mechanism.
