Strengths of Cold Forging: Eco-friendly Processing with Near-Net Shape

By manufacturing forged workpieces in a shape close to the product shape, it is possible to reduce chip discharge and shorten processing time compared to full cutting.

We conducted eco-friendly processing with near-net shape technology. Here, we will introduce the strengths of cold forging processing. For all-cut products, the processing time is 207 seconds per piece, and bar materials generate additional scrap at both ends. Processing of non-simple cylindrical shapes takes more time, and often, internal irregular shapes in small diameter holes cannot be processed. In the case of cold forging plus cutting finish products, the processing time is a total of 136.32 seconds per piece. Since we cut from coils, the amount of scrap relative to the number of pieces is minimal, and irregular shapes can be processed efficiently due to mold transfer. (Especially for the inner diameter section) 【Objectives】 ■ By shaping the product close to its final form through cold forging, we reduce the discharge of scrap and chips (resource conservation). ■ Only the necessary parts are machined or finished to meet the required precision. ■ The crystal structure of the material becomes denser through forging, improving toughness. ■ Fiber flow (forging flow lines) occurs, enhancing strength. *For more details, please download the PDF or feel free to contact us.
