Four Columns Double Acting Stretching Hydraulic Press Machine
YA28 series are four columns structure, composed of hydraulic edge pressing assembly and material returning assembly. The machine can be equipped with photoelectric protective devices and step less pressure adjustment. The major hydraulic parts, seals, electric control parts are world famous products. This series machines are particularly suitable for sheet stretching, forming and flanging etc. of aluminum sheet, stainless steel sheet, and also suitable for forming metal parts in cold extrusion.
Technical features of standard version machines:
1.Low energy consumption, low noise
2.High precision, high speed
3.Over pressure and overrun automatic stop
4.Oil seal adopts multi rings guiding technology, with reliable performance
5.Cartridge inserted valve support technology, guarantying that the centre beam does not drop
