Injection Molding Machine For Fork
ENERGY SAVING MACHINE for Fork

1. Faster response and higher accuracy. The MYTAO servo Energy-saving Injection Molding Machine only needs 30ms from standstill to reach the rated speed. The reproducibility of low-pressure and low-flow is ±0,5%, and the hysteresis of the frequency conversion motor is avoided. Compared with the traditional injection molding machine, the speed response of its pressure and flow is about 0,03s, which can not only significantly improve the repeat accuracy, but also the position accuracy can reach within 0,1mm.
Stable injection, more worry-free
One-line two-cylinder balanced injection device, which significantly improves the injection stability, high repeatability, and avoids welding marks and uneven density
The injection unit adopts a modular pallet seat design, a one-line double-cylinder balanced injection device, so that the screw is evenly stressed during the injection process, significantly improves the injection stability, and makes the barrel positioning more accurate
High-rigidity wide template design, combined with high-safety tie rods, improves the rigidity and stability of the clamping structure as a whole
