This article discusses the application and difference of hot forging and cold heading processes in fastener products. A hidegfejezés teljesen gépesített, resulting in a low defect rate, but the strength of products produced is limited to a maximum of 10.9 and requires heat treatment to reach higher strength levels. Cold heading machines have a basic minimum order quantity of 1 tonna. Másrészt, hot forging involves manual labor and can produce products with up to 12.9 erő. Viszont, the labor cost is high, and the hot forging process is more expensive than cold heading in mass production.
