Hanging Rails Shot-Peening

At the Gottmadingen location, we work with 2 shot-peening installations, 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 dirtfree and dustfree surfaces, especially just before painting or before assembly in engines and transmissions
• Final shotpeening after machining: to achieve closed surfaces with a higher hardness and resistance to wear
• The chosen abrasive is either from the same material as the parts to clean (metal, castings, stainless steel), or with a conserably lower hardness (glass beads, etc.)

The main advantages of a "hanging rails 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 2 tons 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 center complements ideally the press-line, the NC-machines and the paint-shop.

The second shot-peening center is available to work with special abrasives to suit the needs of special parts (stainless steel) and others.
