The forging technique, we are specialized in, is called upset forging. Upsetting is a hot forming process, where parts of the workpiece can be thickened to a multiple of its initial diameter. After heating up the bars or pipes, the workpiece is brought into the desired shape, undergoing several forming steps in one forging die.

This forging process does not only save material, it also enforces the structure of the workpiece.

Compared to the commonly applied „hammer forging“ technique, upsetting enables a far greater ratio from the initial to the final diameter of the workpiece. Additionally you are able to forge selective parts of a workpiece, almost burr-free and therefore very efficient. Due to low costs in manufacturing the forging dies, upsetting is extremely economical, even in small batches!

An upsetting process prior to CNC-lathing or milling is offering the following benefits:
• Cost reduction due to less material usage, especially with expensive material, such as high-alloyed or stainless steel
• Time and energy savings at the subsequent lathing or milling process
• Reduced scrap-rate when machining due to prior expanding or upsetting the workpiece
• Less wear-out of tools and therefore time-savings on tool-changes

Should you work out of block or solid material now, we can calculate for you, if upsetting the workpiece prior to your machining process will pay off.

Of course we can offer you the complete machining of the upsetted forging piece. By performing in-house heat & surface treatments as well as customized laser marking and labeling, we can provide a finished product.

Potential Products:

Classic tool products: wheel spanners, 4-way lug wrenches, tool extension

Products for the machining industry: valve discs/plates, poppet valves, spool take-ups, guide flanges, drive shafts, spindles

Products for the automotive industry: upsetted pipes; the wall thickness of the pipe-end is doubled and through that enforced. The forged area is thereafter strengthened for further machining or welding-on.
