DROP FORGING / OPEN DIE FORGING

DROP FORGING

Drop for­ging is a cost-effec­ti­ve method of manu­fac­tu­ring for metal com­pon­ents with opti­mal strength pro­per­ties. Thanks to near-net-shape for­ging, the fol­lowing machi­ning pro­cess can be signi­fi­cant­ly redu­ced. The material’s strength pro­per­ties are great­ly impro­ved due to the com­pres­si­on of the mate­ri­al and the main­ten­an­ce of the grain ori­en­ta­ti­on. Drop for­ging is pro­fi­ta­ble even for pro­du­cing small batch sizes.

PLANT & MACHINERY

  • 7 drop ham­mers with a power ran­ge from 12.5 kJ to 125 kJ
  • Dif­fe­rent pres­ses to pre-for­ge, com­press, bend and cali­bra­te, with a power ran­ge from 10 t to 400 t
  • Induc­tion, oil and gas furnaces

MATERIALS

  • Alloy­ed and unal­loy­ed steel
  • Stain­less high-gra­de steel
  • Tita­ni­um alloys
  • Alu­mi­ni­um alloys
  • Nickel-base alloys
  • Cop­per alloys

BENEFITS OF DROP FORGING

  • Ide­al grain orientation
  • Mini­mal mate­ri­al consumption
  • Low machi­ning costs
  • High fati­gue strength due to opti­mal grain ori­en­ta­ti­on and microstructure 
  • Gas- and liquid-tight structure

  • A cost-effec­ti­ve method of manu­fac­tu­ring, pro­vi­ding opti­mal strength properties.

OPEN DIE FORGING

Open die for­ging is par­ti­cu­lar­ly sui­ta­ble for pro­to­ty­pes, repla­ce­ment parts and small size bat­ches. Usual­ly the­re are no addi­tio­nal too­ling cos­ts. Spind­les, flan­ges and rings are typi­cal­ly open die for­ged. Open die for­ging and drop for­ging can be com­bi­ned in order to achie­ve the ide­al manu­fac­tu­ring process.
