Sheet metal forming: stamped part

Sheet Metal Forming

is the generic term for all production methods that involve changing the shape of metals by plastically deforming them in a specific way at low temperatures. It is performed on a semi-finished material that has already undergone primary forming (a metal sheet). The material retains its mass and cohesion during the forming process.

Deep Drawing of Sheet Metal

Deep drawing is one of the key forming processes used in sheet metal working. Its applications include large-scale as well as small-batch production, e.g., it is used in the automotive industry, aviation, or medical technology.

We produce our deep-drawn parts on presses and drawing presses using rigid tools:

  • Hydraulic drawing presses (40 to 315 tonnes), bed sizes: 560x560 to 1,100x1,250 mm
  • Transfer press with 8 stations, 120 tonnes
  • Cutting, crimping, thread cutting machines, etc.
Progressive Press für Deep Drawing

Transfer Press

If the final draw depth cannot be achieved in a single drawing operation, the workpiece is progressively drawn (transferred) through multiple stations.

Reverse Drawing

Reverse drawing is a special deep drawing technique that only a few sheet metal working companies have managed to master. We are one of them.

Stamping / Bending

When sheet metal working is a question of stamping and bending metal parts that are required in large quantities, it is more cost-effective to rely on machines or systems that use specific tools (for stamping/bending) because they can combine several essential processes in a single operation. The high cycle speeds of our automatic stamping presses save you both time and money.
Stamping and bending are performed on:

  • Eccentric presses with a stamping force of 40 to 100 tonnes, bed sizes: 400x585 to 690x1,000 mm
  • Four-column automatic stamping presses with stamping forces of up to 200 tonnes, bed size: 900x1,600 mm, feed and straightening unit for widths of up to 400 mm and thicknesses of up to 4 mm
  • An automatic stamping and bending machine
  • Straightening systems, notching machines, plate shears

Laser Cutting

In the field of sheet metal working, laser cutting is the preferred method for workpieces with complex contours that have to be machined quickly and precisely. This noncontact process offers a cost-effective method for cutting sheet metal even when the batch sizes are very small. Laser cutting is performed on:

  • A laser cutting system (working area: 5,000x1,550 mm)
    Sheet steel up to 16 mm thick
    Chrome steel up to 12 mm thick
    Aluminum up to 8 mm thick

 

Folding / Bending / Embossing

For the majority of metal sheets that we fold or bend as part of our sheet metal working (metal machining) operations, we use standard tools. However, if the parts are highly unusual or complex, we create the special tools that we need to produce them. The bending and folding operations are performed consecutively on combination machines. Folding and bending are performed on:

  • A CNC press brake with a force of up to 80 tonnes (working area: 2,500 mm)
  • Embossing presses

 

Joining

is the process of linking individual parts to create functional units. A variety of processes can be used: welding, riveting, soldering/brazing, clinching, etc.

Press Joining

Press joining (also known as clinching) is a method for connecting metal sheets without having to use a filler metal. It can be classed as both a joining process and a forming process because the connection is achieved by forming the material.

Longitudinal Seam, Spot, Pressure, and Stud Welding

Welding is the process of connecting metallic surfaces by applying heat and pressure. The metals are heated to a pasty state so that they mingle and become connected. We carry out welding using the specified method and:

  • Tungsten and metal inert gas welding systems (TIG/MIG)
  • Pressure and spot welding systems
  • A (3-axis) CNC stud welding system

Riveting

is the process of permanently joining two or more parts by compressing a connecting element – the rivet – to form a non-positive (hot-riveting) or positive (cold-riveting) connection.

  • Riveting machines

Soldering/Brazing

is a thermal process for joining materials through substance-to-substance bonding. A liquid phase is formed by melting a solder (fusion soldering) or by means of diffusion at the faying surfaces (diffusion brazing). This creates a surface alloy but there is no deep fusion of the workpiece: The liquidus temperature of the base materials is never reached. As the solder/brazing solder solidifies, a substance-to-substance bond forms similar to the one created during welding.

  • Hard soldering (brazing) and soft soldering
