PLA sheet extrusion production line

PLA sheet extrusion production line
Polylactic acid, also known as polylactide, belongs to the polyester family. Poly (lactic acid) is a new type of biodegradable polyester material produced by polymerizing lactic acid as the main raw material, commonly known as corn plastic. It has abundant sources and can be regenerated. It is mainly made from L-lactic acid produced from corn and cassava, and undergoes processes such as condensation, cracking, purification, and polymerization. The production process of polylactic acid is pollution-free, and the product can be biodegraded to achieve circulation in nature. Therefore, it is an ideal green polymer material and a high-tech environmental protection product encouraged by the country. It is widely used in fields such as electronic product casings, automotive parts, medical equipment, clothing fibers, agricultural film, food packaging, tableware, etc.

The Jinweier Machinery PLA sheet extrusion production line is suitable for the production of PLA (polylactic acid) and modified PLA. PLA (polylactic acid) originates from plant resources and can be directly used for extrusion molding. PLA and biodegradable PLA are widely used in various food packaging and hardware packaging due to their biodegradability, compostability, recyclability, and other characteristics Equipped with a melt metering pump for quantitative extrusion, with closed-loop control of speed and pressure to ensure uniform thickness of the sheet. The rollers are independently driven, and the linear speed of each roller is synchronously controlled. The whole machine adopts PLC control, which automates the functions of actual parameter setting, data calculation and feedback, alarm, etc

Multiple extruders can be used for co extrusion technology to produce multi-layer co extruded composite PLA or starch sheets, which are widely used in thermoforming, printing, hardware packaging, etc.
*Equipped with precision distributor, uniform layering, adjustable proportion of each layer, and digital control accuracy.
*The inclined horizontal tablet structure makes operation and maintenance more convenient.
*The roller has independent power, and the linear speed is synchronized with the extruder speed through closed-loop control.
*The whole machine adopts PLC control to achieve automatic control of parameter setting, data calculation and feedback, alarm and other functions.
*The electrical control system and operating procedures were independently written by Kingwell
