Stamtec is a leader in forging press technology. Our cold and warm-hot forging presses are recognized for their durability, repeatability and ability to reduce scrap. But many of our customers are unfamiliar with the process.

Here are a few facts to demystify the process.

What is a forging press?

A forging press forms parts from a billet – a length of round metal – rather than stamping pieces out of a sheet of metal.

What are the benefits of using a forging press?

Better part finish and a scrap reduction rate between 40% and 60% are two of the primary benefits. The reduced scrap rate means forging presses provide one of the most economical methods for manufacturing high precision parts. Stamtec forging presses also offer:

• Near-net shapes
• Higher productivity
• Superior plasticity
• Better mechanical characteristics

What is hot forging?

A hot forging press operates at temperatures as high as 1150 degrees Celsius. Because of the softened steel used in the process, warm-hot forging presses can form parts that couldn’t be made otherwise.

What applications are best suited for hot forging?

Hot forging presses are used to manufacture hand tools and automotive parts like steering components, connecting rods and bearing housings, as well as taper roller bearings, valves and transmission housings for armored vehicles.

What is cold forging?

Cold forging presses normally operate around room temperature. Because the material is strain-hardened on a molecular level during the forging process, cold forging can produce parts that are stronger than would otherwise be possible.

What applications are best suited for cold forging?

Cold forging is frequently used to make parts like hand tools, automotive shafts and small gears.

How is press forging different from hammer forging?

Press forging uses a slower and continuous pressure to shape metal, while hammer forging literally lives up to its name. In this process, the billet is hammered with multiple blows to form the part.

What production rates are available with forging presses? 

Depending on the application, production rates as high as 10,000-30,000 parts per month are possible.

What tonnage range are Stamtec’s forging presses available in?

We offer forging presses in the 220- to 4,000-ton range.

What type of drive systems do Stamtec’s forging presses use?

Our warm-hot forging presses use oversize eccentric drives, while our cold forging presses use a knuckle joint drive.

Can Stamtec offer a completely automated press line using forging presses?

Yes, we offer a full range of peripheral equipment, including transfer systems, feeders and knock-out devices, to meet your needs.
