King-Mazon provides the tube bending equipment to China traine at the beginning of China train construction.  As you can see the tube shown in the picture, is our high pprecision bend tube. Our team introduced USA's numerical control bend vector calculation technology and then successfully developed tube precision bending technology algorithm, it not only can effectively realize precision tube bendinf for high-speed rail way, but also make all movement is digital control, make the pipe bending technology reached the international advanced level in China.
