CNC Stretch Forming Machine for building facade Curtain Wall variable curvature bending and twist bending.
First order: one arc and two inner arcs
When bending, first press the material between the two arcs, and do not make the material deform in the middle when bending.
After the bending, the two inner arcs of the two inner ribs cannot be removed, and wrinkles may occur.
Solution: A punches the ribs before punching, then bends, repairs and polishes.
B side of the mold plus the slider to clamp the rib position and then bend (forcibly squeeze), it is possible that the rib position is concave, acceptable.
C is allowed to wrinkle, forged and smoothed after molding.
