Stamtec’s cold forging presses are engineered for applications requiring high forming force, dimensional accuracy, and consistent near‑net‑shape production. Cold forging reshapes metal at room temperature, improving grain structure and mechanical properties while reducing material waste and minimizing secondary machining.
These presses support high‑volume production of components such as fasteners, shafts, small gears, hardware, and precision industrial parts. With six cold‑forging platforms available—LF1, KP, KT, KW1 (cold‑forging models), KW2, and KL2—Stamtec provides solutions for a wide range of part sizes, forming depths, and deformation requirements.
The LF1 Series is designed for cold forging, drawing, fine blanking, near‑net‑shape forming, and press forging of sheet materials. These presses support light compound materials such as magnesium and aluminum, as well as sheet steel and high‑tension steels. The compound‑link mechanism provides controlled slide motion suitable for precision sheet‑metal forming.
