Metal punching

Rotary punching technology used on steel, stainless steel and aluminium

Compared to paper, metal is a lot stronger and subsequently requires higher punching force. The metal punching process calls for the intelligent and effective use of well engineered punching machines, integrated in a continuous fabrication line. Steel, stainless steel and aluminium are just a few examples where Baust rotary punching technology is used in the metal industry.

Punching metal: many possible applications

Among the many possibilities for using rotary punching on metal, the most frequent applications include, for example, metal coil material to be punched and in combination with a following roll-forming process to ultimately make profiles such as

  • plaster corner brackets
  • edge protection
  • protective grating
  • racks
  • cable ducts, cable trays, cable ladders
  • and many more

In principle, it is possible to punch all materials made from metal coils. It plays no role whether it is steel, stainless steel, aluminium or other non-ferrous metals. Only the thickness of the punched material varies: from 0,1 mm to up to 3 millimeter material thickness.

Punching stainless steel with effective punching technology

Stainless steel is an extremely popular material. It is corrosion resistant, environmentally friendly and can be machined in a great variety of ways, so that it can be used in a great variety of areas. One decisive advantage here is the high resiliency, making this material sometimes more difficult to punch. Baust Stanztechnologie punches stainless steel, too. The rotary action helps to smoothly release the material from the punch. That way, the force of the punching machine is used effectively without deforming the part being punched. Rotary punching can punch stainless steel up to a thickness of 2 mm.

Rotary punching: Processing aluminium according to the customer's request

Aluminium is an extremely light metal, which still has outstanding strength despite its low weight. In addition, it reflects light and conducts electricity very well. These properties make the metal into a popular material in the electric and building industry. The punching machines from Baust are ideal for punching aluminum, too. When punching aluminium, the punch moves onto the metal, similar to stainless steel. As the rotation goes on, more pressure is applied, forcing the punch exactly into the outline of the female die corresponding to the shape to be punched out. All edges in web direction are sheared by degrees with less force rather than being all hit at once. Since the manufacturing process for rotary punching is continuous (in contrast to conventional punch presses), it is extremely fast and cost-effective. By punching metal this way, production of high numbers in the shortest possible time with constant quality can be ensured.
