Knuckle joint press is ideal for forming operation where cloe tolerances are required. It is designed for operation which require slow but high force at lower zone of the stroke, therefore perfectly suited for coining, extruding, sizing and thick plate blanking. By virtue of the linkage system, the ram speed is very slow as it approaches the BDC. This low punch entry speed allows enough time to provide plastic flow of material during critical cold forming zone.

Advantage:

In comparison to sheet metal forming, the cold forging technology can reduce the material waste form 40% up to 60%. One of the most economical method for manufacturing high precision parts for metal. It also offers more accurate, stronger and longer life parts.
