SX10 is the first high-speed stepless roller forming equipment in history that does not need to change the knife after forming and cuts quickly. The stepless conversion system is independently researched and developed by our company. This system is widely used in cold metal roll forming machines such as C&Z Purlin Roll Forming Machine and C Purlin Roll Forming Machine. The stepless transformation can continuously obtain the transformation system of any specification within the transformation range. The stepless technology is mainly manifested in stepless changeover and stepless shearing. The stepless conversion system can be adjusted in millimeters within the specifications. It can produce not only standard sizes, but also non-standard sizes. Later, more other models came into being according to the different needs of customers.
