  1. China XIYUAN is used as a press manufacturer. The use of advanced photoelectric protection technology can greatly improve safety performance. The cooperation of computer counting and programs can realize the unattended processing process, which greatly improves the work efficiency and reduces the production cost.


In the field of punching various metal and non-metal pipes and plates, electric punching machines are mostly used to complete the punching. Electric punching machines pollute the environment due to noise and have complex structural components that determine their high cost, difficulty in maintenance, high maintenance costs, and bulky body. And consumes a lot of power. The operation is complicated, the failure rate is high, and the safety hazard is great.


  1. As a press supplier, China XIYUAN has a simple structure and low production cost. It adopts pneumatic technology to realize that one air compressor can work for multiple pneumatic punching machines simultaneously, which is more energy-saving than electric punching machines. Reduce power consumption. The operation is simple, the safety type is high, and the foot switch is used to control the solenoid valve, the structure is simple, the failure rate is low, and the production efficiency is improved.


It is suitable for punching various metal and non-metal pipes and plates.
