China Suppliers Factory JSFTWIN Sulfuration Foam Thermo-Forming Machine for Quality Plastic Flooring Solutions
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 (FAQ)
What is the difference between extrusion and calendering molding principles?
Extrusion molding shapes the plastic floor billet by forcing a melted, uniform plastic mixture through a specific mold using a rotating screw. Calendering molding, on the other hand, extends the plastic melt into sheets or films by passing it through a set of rotating compression rolls.
What are the main components of the structural composition?
The system is composed of five key sections: the Extrusion system (hopper, screw, barrel), the Mold system (extrusion or calendering molds), the Cooling system (water tank, rolls), the Traction system (rolls and motors), and the Cutting system (tools and motors).
What is the nominal pressure range of the JSF series?
The nominal pressure ranges from 120 tons for the entry model (JSF-120×2F) up to 1000 tons for the heavy-duty model (JSF-1000×2F).
How many heating plate layers do these forming machines have?
Most models in the JSF series features 10 heating plate layers, while the JSF-500×2F model is designed with 12 layers.
What are the electrical power requirements for these models?
The electrical power required varies by model: JSF-120×2F requires 15 kw, JSF-300×2F and JSF-500×2F require 19 kw, JSF-650×2F requires 26 kw, and the largest JSF-1000×2F model requires 47 kw.
How does the cooling system work in the production process?
The cooling system utilizes a cooling water tank and cooling rolls to rapidly cool and solidify the hot plastic floor immediately after it exits the extrusion or calendering molds, ensuring structural stability.
