1.       The hydraulic machines used throughout the design,pressure,with a solid. Pressure-and pressure margins,and beams can once completed,can separate operation,flat'kits and special packets margin design shoes margin,can operate using a machine use,cost-effective high.
2.       Apply various types of shoes,non-general-pressure air sac wall and the end of the comparable.
3.       Use special design several Federated Pai-hydraulic tanks meet shoes margin irregular contours,pressure on margins and balance,on end and the results excellent.
4.       Yagan interlinked designed to pressure the soles on,the power evenly, did not produce gaps;Yagan automatically generating design and positioning to shoes to impede or facilitate access to harvest, and without damage to the uppers,with the exception of general footwear,whether long-or semi- long-shoes are convenient to operate.
