Product Features

The one-piece hyperbolic elbow five-fulcrum clamping mechanism integrates a strong and solid frame structure to ensure that the formwork is balanced and rigid. Ensure that the clamping parts are high-speed and smooth.

The robust and wide formwork mills the "T" slots and standard screw holes according to the EUROMAP standard. And it has bigger distance between tie-bar.

The hydraulic ejection cylinder retracts and contracts freely. The movements are extremely precise. And there are multiple ejector rods.

Adjust the skateboard in the form of barium under the moving plate. Can bear part of the mold weight. Reduces the load on the tie-bar. Avoid failures that may occur when using heavier molds.

The use of high-flow and high-precision hydraulic system makes the whole machine speed up. Compared with the same level of machine speed increase of up to 20%, and the supporting motor power is large, so that the motor overload is greatly reduced, compared with the quantitative pump, the power saving is 25%-80%.

Equipped with a tight oil leaker, it effectively removes the pollution of the oil circuit system, reduces the chance of machine maintenance, and prolongs the service life of hydraulic components.

The inside of the tank is treated with plastic spray. in the piping system, it is equipped with a large-diameter high-pressure hose to make the system noise less and the oil return back pressure lower .
