PET PLA sheet extrusion production line

The Jinweier PET sheet extrusion production line is a strategic and continuous improvement model of the company. The company adopts a special price sales model to ensure the market share of the first place. The same parameter configuration achieves the lowest price, and continuous technological upgrades ensure that it is always in the first tier of the PET industry. The processing materials can process APET, PETG, RPET, etc. Classification introduction of PET sheet extrusion production lines:
1. PET sheet single screw production line: APET, PETG, CPET sheet single screw extrusion production lines are currently the most mature and stable production solutions, generally using single or double machine co extrusion forms. Jinweier adopts the latest technology to improve the comprehensive efficiency of this model by 30%
2. PET sheet single screw exhaust production line: This model only requires crystallization of PET and does not require drying. Its advantages include low energy consumption, simple process, convenient equipment maintenance, and the ability to ensure the formation of 18CM deep vacuum cups.
3. PET sheet twin-screw exhaust production line (crystallization free drying): The crystallization free and drying free exhaust PET sheet unit launched by Jinweier has the advantages of low energy consumption and high efficiency. This model is a continuously improved and upgraded product of Jinweier Company. The core vacuum system has been significantly upgraded from the original Roots water ring pump group to Roots rotary vane pump group, which can achieve a vacuum degree of ≤ 10Pa. At the same time, the PET special alloy steel thin-walled roller group is used to greatly improve the cooling efficiency, thereby increasing production, improving product toughness and transparency. The operating system independently programmed by Kingwell ensures the humanization and ease of operation of the device.
4. PET sheet planetary multi screw exhaust production line (crystal free drying): Using a planetary screw extruder as the main machine, it increases the area of material and air, and combined with the latest vacuum system developed by Jinweier, it can meet the needs of customers with large output and high-quality sheets.
Multiple extruders are used for co extrusion technology to produce multi-layer co extruded composite PET sheets, such as APET/PETG, PETG/APET/PETG, APET/RPET/APET, and other multi-layer composites. Widely used in vacuum forming, printing, hardware packaging, gift folding, etc.
*Equipped with precision distributor, evenly layered, adjustable proportion of each layer, and digital display.
*The inclined horizontal tablet structure makes operation and maintenance more convenient.
*Roller independent transmission, synchronous closed-loop control of linear speed and extruder speed, fully servo system.

*The whole machine adopts Siemens PLC control to achieve automated control of parameter setting, data calculation and feedback, alarm and other functions.

*The operating program and control system were independently written by Kingwell.

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
