China Suppliers Factory JSFTWIN Sulfuration Foam Thermo-Forming Machine for Plastic Flooring Production
Working Principle
- 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.
Structural Composition
- 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.

Frequently Asked Questions
Q1: What is the extrusion molding principle of the plastic floor machine?
A1: It operates by rotating a screw in the extruder barrel to convey, compact, melt, and plasticize raw materials (such as plastic pellets) into a uniform melt. This melt is then forced through a specifically shaped mold to form the floor billet, which is subsequently cooled and shaped.
Q2: How does the calendering molding process differ from extrusion?
A2: While extrusion pushes the melt through a shaped mold, calendering feeds the plasticized melt into a set of counter-rotating rolls. The compression and stretching action of these rolls extends the melt into a sheet or film of precise thickness and width before cooling and traction.
Q3: What are the primary systems that compose the machine's structure?
A3: The machine consists of five core systems: the extrusion system (hopper, screw, barrel), the mold system (extrusion or calendering molds), the cooling system (water tank, cooling rolls), the traction system (rolls and motors), and the cutting system.
Q4: What role does the traction system play in production?
A4: The traction system, comprised of traction rolls and motors, is designed to pull the newly formed plastic floor out of the mold and control the speed at which it is conveyed through the rest of the line.
Q5: What is the nominal pressure range across the different models?
A5: The nominal pressure varies by model, starting from 120 tons for the JSF-120×2F model, up to 1000 tons for the heavy-duty JSF-1000×2F model.
Q6: What are the power and weight specifications for the largest model?
A6: The largest model, JSF-1000×2F, has an electrical power rating of 47 kw and a total weight of 90,000 Kg.
