overhead shot-peening

At the Gottmadingen location, we work with a shot-peening installation, mostly for series parts:

• First shot-peening after casting: directly after taking the castings out of the foundry sand
• Cleaning of metal-parts: to eliminate corrosion, flitter and old paint
• Final shot-peening of castings: to achieve dirt-free and dust-free surfaces, especially just before painting or before assembly in engines and transmissions
• Use of 3 turbo blasters for high power and reduction of time and costs

The main advantages of a "overhead feeding system" are:

• The parts do not touch each other and do not fall about; therefore there is no bending of thin-walled structures and no surface damage
• The parts are perfectly accessible to the abrasive; even difficult areas in deep recesses can be reached in automated processes, see the picture below
• Also heavy parts up to 1000 kg can be hooked onto the support structure and then shot-peened at low cost in our automated process

Heavy parts up to 4500 kg are shot-peened separately; either in the machine or separately.



This in-house shot-peening centre complements ideally the press-line, the NC-machines and the paint-shop.
