Product Overview
This automatic steel door frame roll forming machine is specially engineered to produce high‑precision metal door frames for security doors, fire‑rated doors and steel entry doors. The complete production line integrates uncoiling, feeding, multi‑station roll forming, hydraulic punching and automatic cutting, realizing one‑step forming of door frame profiles from plain steel coils.
Adopting heavy‑duty gear‑box drive structure, the machine delivers stable running performance, high forming accuracy and long service life. It can process galvanized steel, cold‑rolled steel and other raw materials, supporting custom‑made profiles according to clients’ drawing requirements. Finished door frames feature neat surface, consistent dimension and excellent interchangeability, widely applied in door manufacturing factories worldwide.
Main Features
- Heavy‑duty Forming Structure: High‑strength machine frame together with solid gear‑box transmission ensures stable operation under long‑time continuous working condition, effectively avoiding profile distortion.
- Integrated Hydraulic System: Equipped with high‑efficiency hydraulic unit for online punching and flying cutting. Profiles are cut to exact length without secondary processing, greatly improving production efficiency.
- PLC Automatic Control System: Human‑machine touch‑screen interface supports parameter setting of length, quantity and speed. It realizes automatic counting, fault alarm and easy operation.
- Flexible Customization: Rollers can be modified to produce various sizes & styles of metal door jamb profiles, adaptable for security doors, fire doors and interior steel doors.
- High‑quality Finished Profiles: Tight tolerances for dimension, smooth surface without scratches, finished frames fit perfectly for subsequent welding and assembly.
