Forming:
Getting the shape right
Forming technology gives sheet metal the correct shape. Here, our production machinery gives us great freedom in the design and processing of complex shapes. When necessary, we also transfer know-how from other manufacturing technologies, e.g. investment casting or machining, and combine forming with CNC processes.
Deep drawing
Deep drawing – the cold pressing of cut sheet metal into an open hollow body – can be used to produce a wide variety of shapes. We use computer-controlled deep-drawing presses with up to 400 tonnes of pressing force, and employ an in-house graduated heat treatment process to protect the material. We manufacture the necessary tools ourselves. If required, we also develop new processes.
Edging (cold forming)
Edging involves bending surfaces a precise angle along their entire bending line. This method is also suitable for difficult shapes and tight radii. As this is a cold forming process, the sheet metal is not exposed to heat. This increases the strength of the sheet-metal parts. On our press brakes, we can form sheet-metal pieces up to 4 metres long, using a pressing force of up to 250 tonnes. Thanks to our fully automatic bending robot, we can also process high parts volumes.
Round bending (rounding)
Round bending can be used to produce round and conical parts, including parts with distinct radii. The technique can thus be used to produce, for example, ellipses, ‘rounded triangles’ and ‘rounded squares’ – i.e. pieces of sheet metal rounded to create these shapes, with a minimum corner radius of 120 millimetres. Ringele uses CNC-controlled four-roller bending machines.
