JSFTWIN Sulfurationfoam Thermo-Forming Machine

• Extrusion molding principle: Through the rotation of the screw in the extruder, the raw materials such as plastic pellets are conveyed, compacted, melted, and plasticized in the barrel, making them into a uniform melt with certain fluidity. Then, under the extrusion of the screw, the melt is extruded through the specific shape of the mold, forming the plastic floor's billet, which is then cooled and shaped in subsequent processes to obtain the plastic floor product.

• Calendering molding principle: The plastic melt that has been plasticized is fed into a set of relatively rotating rolls, and through the compression and stretching action of the rolls, the melt is extended on the surface of the rolls into a plastic film or sheet with a certain thickness and width. After cooling, traction, and other processes, it becomes a finished plastic floor. 

• Extrusion system: Consisting of a hopper, screw, barrel, etc., it is responsible for the conveying, melting, and extrusion of raw materials. 

• Mold system: Includes extrusion molds or calendering molds, which determine the shape, size, and surface pattern of the plastic floor. 

• Cooling system: Usually includes a cooling water tank, cooling rolls, etc., which are used to cool and shape the plastic floor after extrusion or calendering. 

• Traction system: Consisting of traction rolls, traction motors, etc., it is used to pull the formed plastic floor out of the mold and control its conveying speed. 

• Cutting system: Generally includes cutting tools, cutting motors, etc., which are used to cut the plastic floor according to the set length or size.
