Drawbenches and Drawing Machines Information

DrawbenchDrawbenches and drawing machines use tensile forces to reduce the size of metal sheets, wire, tubes, and rods by drawing metal strips through a drawplate or dies.


Drawing is typically broken up into two general types:

  • sheet metal drawing 
  • wire, bar, and tube drawing.

Sheet metal drawbenches and drawing machines involve plastic deformation over a curved axis. The flow and stretch of material is necessary for successful forming. With sheet metal drawbenches and drawing machines, a die forms shapes from flat sheets of metal, it is necessary for the material to move into the shape of the die. Metal drawbenches and drawing machines can be used to form ductile materials, including aluminum, copper, nickel, mild steel, stainless steel, and magnesium. Wire, bar, and tube drawbenches and drawing machines draw stock through a die mounted on the draw bench to reduce the diameter and increase the length. The end of the workpiece is placed in grips and the rest is pulled through the die of the drawbench or drawing machine.

Other common types include hydraulic drawbenches and drawing machines and dual chain drawbenches and drawing machines. Hydraulic machines use fluid power to pull the material to the die for shaping. These drawbenches and drawing machines provide a smooth drawing action, which eliminates the jerking motion at the start of the draw. Hydraulic drawbenches provide high production capacity over other chain-type drawbenches and drawing machines due to increased acceleration, deceleration, and carriage return speed. Dual chain drawbenches and drawing machines are designed to draw tubing through dies and over internal dies to reduce diameter and improve the finish and yield strength of the tubing. Dual chain draw carriages pull from the centerline of the draw, unlike single chain draws that can pull off-center. These drawbenches and drawing machines typically contain the draw forces within the bench structure to minimize foundation or reinforcement requirements. Other, unlisted types of drawbenches and drawing machines may also be commonly available.


Common materials used with wire, bar, and tube drawbenches and drawing machines include steels, copper alloys, and aluminum alloys. Drawbenches and drawing machines are available in various types to meet a range of applications.
