Flange forming machines are available in mechanical and hydraulic types. They are rolling devices that roll various types of steel into circular or spiral shapes. It has a compact structure and has the advantages of small size, low energy consumption, high efficiency, no noise, easy installation and use, simple operation, strong load-bearing capacity, long life, fast rolling speed, and reliable product quality. The flange machine is a highly efficient rolling device that rolls carbon steel, stainless steel, and non-ferrous metal profiles into rings and flanges with a diameter of с320-6000mm. It replaces the original complicated processes such as steel plate blanking, docking, correction, and lathe processing, and saves oxygen, acetylene, labor, raw materials, etc. It is an advanced mother machine for manufacturing flanges.

This product is widely used in mechanical equipment industries such as fans, bridge formwork, chemical equipment, cable racks, mining explosion-proof switches, and centrifuges. The flange forming machine uses molds on three rollers to roll various profiles such as flat steel, channel steel, round pipes or other special-shaped cross-section profiles into circles, arcs, and spirals with a certain curvature. The mold of this machine is modular and can be applied to a variety of profiles after changing the combination.

Working principle:

The working principle of the molding machine is similar to that of a syringe for injection. It uses the thrust of the screw (or plunger) to transfer the plasticized molten state ( A process in which plastic (in a viscous flow state) is injected into a closed mold cavity and the product is obtained after solidification and shaping. Injection molding is a cyclic process. Each cycle mainly includes: quantitative feeding - melting and plasticizing - pressure injection - mold filling and cooling - mold opening and picking. After taking out the plastic part, the mold is closed again and the next cycle is carried out.
