Description

Ease operation: user friendly HMI, ease for setting parameters and recipe storage; Control system: PLC + HMI (Siemens brand), refer to pressing technology requirement set the parameters on HMI such as pressure, position, hold pressure, multi-pressing, etc; Accuracy monitoring: used for linear scale and pressure sensor to monitor the position and pressure, enhance the pressing accuracy; Position accuracy: repeatability of ram position achieve to ±0.02mm, control the scrap rate of products caused by machine accuracy; Pressing accuracy: repeatability of ram pressure achieve to ±3%, control the scrap rate of products caused by machine accuracy; Energy saving: high power motor fulfill high speed high pressure processing requirement, servo motor driving system can achieve energy saving 30 – 50%; Low noise level: used of servo motor driving system, fulfill different speed and pressure of pressing requirement, ensures the stability of movement, lower noise level; Ram cylinder designed: used of forged steel and its inner surface is finely grinded, prolonging working life under high pressure; Knock-out cylinder: knock-out cylinder fixed inside of ram cylinder; Hydraulic circuit designed: used of advance two-way cartridge valve, high reliability and less impact on changing of different pressing stage; Ease for maintenance: module structure designed as different function requirement, ease to dis-assembly, machine problems can be checked on HMI; Performance of drawing process: changeable of ram and blank cylinders pressing force, can achieve 1 to 1 product forming, save the mold cost; Automation: design of different automatic production equipment as customer requested;
