Wedgerolling for Preforms and as a Substitute for Machining 760137
Wedgerolling is a relatively new hot metal forming process that combines the techniques and advantages of forging, hot extruding, screw machining or chucking, into one automatic process for round bar, billets or heavy wall tube.
Wedgerolling or transverse hot roll forming as we know it today was really perfected and put to actual production use in the late 1950's, originally in Czechoslovakia. It is now used in Russia and in England. It offers both advantages and disadvantages over currently used metal shaping and metal removal processes. It reduces diameters of material, does not intentionally gather like cold heading. Depending upon the particular part applications, it can offer up to 400% in cost savings over popular processes now in production use.
