Hard and smooth screw assembly are special for MIM. The compression ratio, flow length ratio, three-section ratio, and other parameters are designed for the characteristics of raw materials. All of them are made from imported materials and conform to strict tolerance standards.
The screw assembly can stabilize the plasticizing temperature to achieve high-quality plasticizing and mixing, and are more wear-resistant and durable to provide high injection precision.

|
Upgrade mold adjustment structure and thicker platens contribute to high-pressure clamping without loosening and low deformation of the clamping unit. Strengthened toggles and cross plate of the clamping unit optimize the clamping curve, improve durability, and accelerate mold opening. |
 |
 |
The high-power servo drivers are matched with the high-torque servo motors and permanent magnets at the highest SH level. This power train is designed for low RPM and high torque, with sufficient overload capacity and consistent performance in reliability tests under adverse conditions.

|
The movable platen has copper-alloy double slides that increase the force area and reduce the pressure of alloy plates, more long-lasting than using regular single slides. The slides have a good load-bearing support ratio for fast and heavy mold opening and closing, and also guarantees force uniformity in toggles and tie bars. |
