Press the process by which a piece of metal in the cross sectional area of the mouth of the mold under high pressure is low In general, two main types are press,Two main types of press working pressure are direct and indirect pressure or reverse the so called press.

Hot Press

Due to the much more pressing action under the hot metal that contains metal resistance change is very small presses,Most pressing is done directly by hot pressing process.

The main variables that affect the force required to press

1 - Type

2 - Press about

     AO:Cross-section of befor the press

     AF:Cross-section of after the press

3 - Working temperature

4 - Deformation rate

5 - Terms of friction within the walls of the chamber and press

Cold Press

Cold pressed the cold work piece material and wire rods for small parts Car-pin plugs are like body-cans-cylindrical hollow-parts with axial symmetry.

Pressing machines

Pressing machines without removal tools that are reshaping the way Such as deep drawing, cutting, repression, extrusion.

Mechanical Presses

Mechanical press to move and hit the flywheel method used,As the desire limp, lever, eccentric and built the most common and most important is the desire to limp out of the center.

Hydraulic Press

Press hydraulic cylinder and piston of a large integrated course piston and kicker are made Oil pressure, she moved into the cylinder driven localises around the site and press done,Hydraulic press to press the cylinder is located at the top of the column or they can be distinguished. Usually Drprs hydraulic pressure is bar (300-200).
