PET sheet extrusion production line

The Gwell PET sheet extrusion production line is a strategic and continuously improved model of the company. The company adopts an appropriate price sales model to ensure market share, with the same parameter configuration achieving low selling prices, and continuous technological upgrades to ensure that it always ranks in the PET industry. The processed materials can be processed into APET, PETG, RPET, etc. Introduction to the classification of PET sheet extrusion production lines:

1. PET sheet single screw production line: APET, PETG, CPET sheet single screw extrusion production line is currently a mature and stable production plan, generally using single or double machine co extrusion form. Jinwei adopts new technology, which improves 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 vacuum forming of 18CM deep cups.

3. PET sheet twin-screw exhaust production line (no crystallization drying): The PET sheet unit with no crystallization and no drying exhaust introduced by Gwell has the advantages of low energy consumption and high efficiency. This model is a continuously improved and upgraded product of Gwell Company. The core vacuum system has been significantly upgraded from the original Roots water ring pump group to the Roots rotary vane pump group, which can achieve a vacuum degree of ≤ 10Pa,, At the same time, the use of PET special alloy steel thin-walled roller groups significantly improves cooling efficiency, thereby increasing production, improving product toughness and transparency. Kinwell's independently programmed operating system ensures the humanization and ease of operation of the device.

4. PET sheet planetary multi screw exhaust production line (non crystallization drying): Using a planetary screw extruder as the main unit, the area of material and air is increased. Combined with the vacuum system developed by Gwell, it can meet the needs of customers with high production and high-quality sheet materials.

Basic parameters of PET sheet extrusion production line (please consult sales engineer for details)

 

Using multiple extruder co extrusion technology to produce multi-layer co extruded composite PET sheets, such as APET/PETG, PETG/PET/PETG, APET/RPET/APET and other multi-layer composites. Widely used in vacuum forming, printing, hardware packaging, gift folding, etc.

*Equipped with precision distributors, evenly layered, adjustable proportions for each layer, and digital display.

*The inclined horizontal tablet pressing structure makes operation and maintenance more convenient.

*Independent roller drive, synchronous closed-loop control of linear speed and extruder speed, fully servo system.

*The whole machine is controlled by Siemens PLC, achieving automatic control of parameter setting, data calculation and feedback, alarm and other functions.

*The operating program and control system are independently written by Gwell.

PLA sheet extrusion production line

Polylactic acid, also known as polylactide, belongs to the polyester family. Poly (lactic acid) is a polymer obtained by polymerization of 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 as raw materials, and is a new type of biodegradable polyester material through processes such as condensation, cracking, purification, and polymerization. The production process of polylactic acid is pollution-free, and the product can be biodegradable, achieving circulation in nature. Therefore, it is an ideal green polymer material and also a high-tech and environmentally friendly product encouraged by the country. It is widely used in electronic product casings, automotive parts, medical equipment, clothing fibers, agricultural films, food packaging, tableware and other fields.

The Gwell 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. Due to its biodegradability, compostability, and recyclability, PLA and soluble PLA are widely used in various food packaging and hardware packaging. Equipped with a melt metering pump for quantitative extrusion, speed and pressure closed-loop control, the film thickness is uniform. The rollers are independently driven, and the linear speed of each roller is synchronously controlled. The whole machine adopts PLC control, with automation of actual parameter setting, data calculation and feedback, alarm and other functions

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 hot forming, printing, hardware packaging, etc.

*Equipped with precision distributors, evenly layered, adjustable proportions for each layer, and digital control accuracy.

*The inclined horizontal tablet pressing structure makes operation and maintenance more convenient.

*The roller has independent power and synchronous closed-loop control of linear speed and extruder speed.

*The whole machine adopts PLC control, achieving automatic control of parameter setting, data calculation and feedback, alarm and other functions.

*The electrical control system and operating procedures are independently written by Kinwell
