WEGENER BM 301 plastic bending machine

WEGENER BM 301 plastic bending machine was built in Germany by Wegener International GmbH. The machine was regularly maintained and upgraded throughout its service life. In 2022, a general overhaul was carried out at the machine manufacturer. WEGENER BM 301 is the perfect choice for precision forming of thermoplastic sheets made of, among others, PVC, PC/ABS and PMMA with a maximum thickness of 15 mm and a width of 3050 mm. The machining process is performed by means of heating elements in the form of a lower flat strip and an upper V-shaped strip, which heat the material at a controlled temperature to a plastic state. The material is then bent to the desired angle between 0° and 110°. The use of the highest-quality heating elements ensures efficient and even heating of the material along the bending line. They are moved manually along hardened steel rollers. Repeatable positioning of the material is, in turn, ensured by a stop at the front of the machine, which can be set at four adjustable fixed points. This stop is connected to the heating elements by a chain drive, which ensures synchronous, counter-rotating movements controlled pneumatically. The machine is operated by means of a relay control with an adjustable time relay, enabling independent setting of heating and cooling times depending on the type and thickness of the material. All controls are located on the central control console at the stop and at the front of the machine. The bending bar is operated by a foot control, while blocking and movement of the bending bar is carried out from the two-hand control. The heating bar is activated by a manual controller. The electronics and pneumatics responsible for controlling the machine are integrated into a side control cabinet. The WEGENER plastic sheet bending machine weighs 1300 kg.
