Wholesale China Multi-Layer Sheet Co-Extrusion Machine Quotes Pricelist – Modified Plastic Sheet & Plate Extrusion Line – JWELL

Adopt building block type co-rotating parallel twin screw extruder, which can compound material and produce the sheet by one step without pelletizing production. The sheet can be used in the industry of electronics, bags and suitcase, automible, building material, and so on.

Advantage: no need to pelletizing, reduce some procedure of cooling, granulating, packaging and re-heating. Saving factory space, and reducing the cost of packaging and electricity comsuption for manufacturers, meanwhile, increasing the productivity.

Main technical specification

Note: The specifications are subject to change without prior notice.

Composition of plastic extrusion machine
The main machine of a plastic extrusion machine is an extruder, which is composed of an extrusion system, a transmission system and a heating and cooling system.

Extrusion system
The extrusion system includes Extruder, Feeding system,Screen changer, Metering pump, T-die. The plastic is plasticized into a uniform melt through the extrusion system, and is continuously extruded by the screw under the pressure established in the process.
Screw and Barrel: It is the most important part of the extruder. It is directly related to the application range and productivity of the extruder. It is made of high strength and corrosion resistant alloy steel.The barrel cooperates with the screw to achieve the crushing, softening, melting, plasticizing, venting and compacting of the plastic, and continuously and uniformly conveys the rubber to the molding system. 

Feeding system: its function is to evenly transport different forms of plastics to the hopper of the extruder.
Screen changer: Its function is to remove all kinds of impurities in plastic
Metering pump: Equipping a pump in front of the extruder, checking pressure before the pump and controlling the speed of extrusion, which can minimizing pulsation and irregular material feeding and ensures the polymer is smoothly extruded and continuously delivered to the die head.  The shell of the pump adopts high-quality alloy-steel and 
the gear uses quenched chrome steel or other high-grade metallic materials which ensures high efficiency and leakage-proof.
T-die: The function of the T-die is to convert the plastic melt that rotates into parallel and linear movement, which is evenly and smoothly introduced.
