Automatic steel door frame production line achieves the automatic processing of various steel and stainless steel door frames, including one-step frame forming, hole punching, and section cutting, through hydraulic stamping. By employing a pre-punching process, it prevents situations where certain door frames cannot be punched after forming. The steel door frame production line can achieve simultaneously roll forming and storing materials without interruption, ensuring maximum production efficiency of the roll forming machine and overall line efficiency. For material storage, we offer two options: material hopper and pit storage.
