Usedto weld circular thermoplastic, during  welding,a  workpiece is fixed on the bottom die,another workpiece is fixed in rotation of the workpiece surface motion. Becausethere is a certain pressure on the two parts, the heat generated by friction betweenthe workpieces can melt the surfaces of the two workpieces and form a confinedand sealed binding. Wherein the positioning rotary melting is rotating at a settime, and instantly stopped at the set position on a permanent fusion.      The product of our company has the features may othercompany's machine not have:       It can be applied to different sizes of the work (weldingsurface must be circular);       For-column structure, completely eliminate the couple andbackwards;       Extended linear bearing designed to move up and downsmoothly, high accuracy;       With adjustable cylinder or servo motor, position moreprecise;       Dual start button and emergency stop button designed toensure safety.          Application Areas:      Automobile parts (such as: fuel filters, air filters,expansion pots, deputy air pumps, etc.);      Commodities ( such as: glass, plastic trash can, etc.);      Toys (such as: stroller wheel, etc.);      Electronic appliances (such as: float, etc.).
