Gwell PET sheet extrusion production line is the company's strategic continuous improvement model. This equipment company adopts the special price sales mode to ensure the first market share. The same parameter configuration ensures the low price, and the continuous technical upgrading ensures that it is always in the first tier of the pet industry. The processed materials can be processed into APET, PETG, RPET, etc.

PET sheet extrusion production line classification introduction:

1. PET sheet single screw production line: APET, PETG, CPET sheet single screw extrusion production line is a scheme with mature technology and stable production at present. It generally adopts the form of single machine or double machine coextrusion. Jinweil adopts new technology to improve the comprehensive efficiency of this model by 30%

2. PET sheet single screw exhaust production line: this model only needs to crystallize pet without drying. Its advantages: low energy consumption, simple process, convenient equipment maintenance, and at the same time, it can ensure the blister 18cm deep cup.

3. PET sheet twin-screw exhaust production line (crystallization free drying): the crystallization free and drying free exhaust PET sheet unit launched by Jinwei has the advantages of low energy consumption and high efficiency. This model is a product of continuous improvement and upgrading of Jinwei company. Now, a major technical upgrade has been made to the core vacuum system. The original roots water ring pump unit has been upgraded to roots rotary vane pump unit, which can make the vacuum degree ≤ 10Pa,, At the same time, the use of pet special alloy steel thin-wall roller group greatly improves the cooling efficiency, thereby increasing the output and improving the toughness and transparency of products. Kingwell's independently programmed operating system ensures the humanization and easy operation of the equipment.

4. PET sheet planetary multi screw exhaust production line (no crystallization drying): the planetary screw extruder is used as the host, which increases the area of materials and air. Combined with the vacuum system newly developed by jinweier, it can meet the needs of customers with large output and high quality sheets.

Multi extruder coextrusion technology is adopted to produce multi-layer coextrusion composite pet sheets, such as apet/petg, petg/apet/petg, apet/rpet/apet and other multi-layer composites. It is widely used in blister thermoforming, printing, hardware bags, gift folding, etc.

* Equipped with precision distributor, it has even layers, adjustable proportion of each layer, and digital display.

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

* The roller drives independently, the linear speed and the extruder speed are synchronized, and the closed-loop control is complete servo system.

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

* The operation procedure and control system are independently written by jinweil.
