The processed material is cold-formed carbon steel wire (SWCH)! An example of door-related parts manufactured for the automotive industry.
We would like to introduce a case study of the production of special forged parts for the automotive industry, specifically "collars (door surrounding parts)." The request involved converting from another manufacturing method to forging (cutting to forging), with a notable feature being the hollow shape (through hole). At our company, we perform post-processing such as heat treatment and plating as indicated in the drawings after forming through machining, and we primarily supply the finished products. 【Production Case Study】 ■ Request Details: Conversion from another manufacturing method to forging (cutting to forging) ■ Features and Innovations: Hollow shape (through hole) ■ Forging Machine Production Capacity: 600,000 pieces/month ■ Processing Material: Cold forged carbon steel wire (SWCH) Material diameter (mm) φ4.0 ■ Machines Used: 2-die 3-blow forging machine ■ Product Size (mm): Maximum diameter φ8.0, hole diameter φ4.0, total length 3.3 *For more details, please refer to the PDF document or feel free to contact us.
