Plastic board bends directly without connecting, notch and welding rod. The bevel is beautiful and without leakage, which carries out the change from manual to full automatic machinery operation that enhances quality, efficiency, reduces cost and shortens production cycle. Full automatic plastic folding machine belongs to electric integrated machinery equipment, which is manufactured according to principle of plastic board becoming soft and melt after heating; it is applicable for all folding of thermal plasticity board and non-crystal material such as PVC, PMMA (Acrylic), PET (polyester) and PS (polystyrene); it has quick speed and the folding treatment is beautiful and has high intension for smooth folding. The bending machine is manufactured according to DVS and CEN standard.
