CNC Stamping Process: Cold stampings are generally no longer machined or require only a small amount of machining. The accuracy and surface condition of hot stampings are lower than that of cold stampings, but they are still superior to castings and forgings, and the amount of cutting is small. Stamping is an efficient production method. It adopts composite molds, especially multi-station progressive molds. It can complete multiple stamping processes on one press, and realize the whole process of unwinding, leveling and punching to forming and finishing. Automatic production. High production efficiency, good working conditions, low production costs, and generally can produce hundreds of pieces per minute.
