Bending

1、Process Introduction | What does the bending machine solve?

One time molding: Fold the metal sheet into any two-dimensional cross-section, eliminating the need for splicing and secondary processing
High precision angle: CNC rear stop material+grating ruler, repeat accuracy ± 0.1 °, meeting inspection free assembly requirements
Small radius bending: minimum inner R 0.2 mm, suitable for sharp edge home appliance panels and precision chassis
Long straightness: 6-meter integral beam, total straightness ≤ 0.3 mm/1000 mm, suitable for elevator cars and car side panels
Complex polygons: multiple bending and automatic mold changing, achieving one-time completion of box, disc, C, and Z shapes
