The gas-liquid booster cylinder is also called the gas-liquid booster cylinder and is generally referred to as the booster cylinder. The gas-liquid boosting cylinder is an improved design that combines the advantages of the air cylinder and the oil cylinder. The hydraulic oil is strictly isolated from the compressed air. The piston rod in the cylinder automatically starts after contacting the workpiece. The action speed is fast and is more stable than the pneumatic transmission. The cylinder device Simple and easy to adjust the output. Under the same conditions, it can reach the highest output of a hydraulic press. It has low energy consumption and soft landing without damaging the mold. It is easy to install and the special boosting cylinder can be installed at any angle of 360 degrees. It takes up little space and has few faults and no temperature. It has core features such as long life, low noise, etc.
