Metal cutting

Pressure processing of metals

Proton-PM’s equipment can be divided into three groups, based on the standard size of processed parts and the kind of operations needed:

  • Equipment meant for treatment of parts up to Ø100 mm;
  • Equipment meant for treatment of parts ranging from Ø 100 mm to Ø 400 mm;
  • Equipment meant for treatment of parts Ø 400 mm and up.

The enterprise has 59 pieces of pressure equipment with press power ranging from 10 tons to 1,600 tons, the 1,600-ton hydraulic press used for making large sheet-metal stamping being the most unique in terms of its capacity.
