Cold Forging is a cold working process by which metal is shaped at room temperature. More specifically, the metal material is squeezed into a die and the finished part assumes the shape of the die. Cold forged products offer many significant advantages over hot forged products and even more so over cast or machined metal products.

Advantages of cold forged products:

  1. Significant material saving – cold forged product is directly shaped and strengthening through plastic deformation, and thus cold forged product provide very significant cost saving over cast or machined metal products. The material saving is very significant in a high volume production, and even more so if the forged product requires expensive materials.

  2. No heating is required – cold forged product is directly shaped without heat expansion and cold contraction, and thus cold forged product has superior surface finish and dimensional accuracy.

  3. Superior dimensional Accuracy – advanced teeth forging technology can produce forged product with JIS class 3-4 precision. No machining process is required.

  4. High production rate – cold forged product has very short production cycle. Large volume of forged products can be produced quickly.

  5. Exceptional forging die life – forging die used in cold forging process has exceptional die life. Forging die are typically made with very expensive material. Cold forging process provides significant cost saving, because forging die used in cold forging process rarely needs to be replaced.

  6. Better mechanical properties – unlike hot forging, the inclusion and grains distortion of a cold forged product follow the contour of the forged product’s surface and thus the cold forged product has better mechanical properties.

  7. Minimized contamination – producing metal parts using cold forging process produce less contamination than any other manufacturing processes.

Cold forging manufacturing process requires significantly more force than hot and warm forging. Heavier and more powerful forging press machinery is required. At Li-Hsing, our manufacturing facility is well equipped with the latest machineries. We have cold forging presses that produce forces ranging from 250 tons to 1200 tons.
