Single Screw PET Plastic Sheet Production Line High Torque High Output

Gwell PET sheet extrusion production line is company's strategic continuous improvement model.The raw materials can be APET, PETG, RPET, etc.
Introduction of PET sheet machine:

1. Single screw production line for PET sheet: single screw extrusion production line for APET, PETG and CPET sheet is the most mature project with the most stable production at present. Generally, single extruder production line or twin-extruder production line is adopted and Gwell uses the latest technology to increase the general efficiency by 30%.The transparency of PET sheet can reach optical level.However, this model has very high requirements for raw material processing, and the PET raw material needs to be crystallized and dried. This can ensure that the produced PET sheet has no crystal points, whiteness, and poor transparency. The main features of PET high transparency sheet: impact resistance, excellent processability, good chemical resistance, and good insulation.The main applications of PET high transparency sheet: food packaging and gift packing
2. PET high transparent sheet single-screw exhaust production equipment: APET, PETG, CPET sheet single-screw exhaust extrusion production line is improved from the PET high-transparent sheet production equipment, which increases the exhaust function, Make the material in the screw barrel easier to remove the gas and excess water in the material. This equipment is not very strict on raw material processing. It only needs to crystallize the raw materials without drying. The quality of the products produced is also very good.
3. PET sheet twin-screw exhaust production line: APET, PETG, CPET sheet twin-screw exhaust extrusion production line is improved from PET sheet single-screw production equipment. The raw material processing non-crystallization, non-drying exhaust type PET sheet unit of this production equipment has the advantages of low energy consumption and high efficiency. This model is a continuous improvement and upgrade product of Gwell. It has made significant improvements to the core vacuum system. The technology upgrades from the original Roots-water ring pump set to the Roots-rotary vane pump set, which can make the vacuum reach ≤10Pa. At the same time, the PET special alloy steel thin-walled roller set is used to greatly improve the cooling efficiency, thereby increase output, improve product toughness and transparency. The operating system independently written by Gwell ensures the humanization and easy operation of the equipment.
4. PET sheet planetary multi-screw exhaust production line (free of crystallization and drying): the planetary screw extruder is used as the main extruder, which increases the area for material and air, and cooperates with the vacuum system newly developed by Gwell. This machine model meets the needs of customers for large-volume, high-quality sheets.

Using multiple extruder co-extrusion technology to produce multi-layer co-extrusion composite pet sheets, such as AB, ABA and other multi-layer structures.which are widely used in thermoforming, printing,decorative pieces,gift packing,Furniture surface decoration etc.

*Gwell independently wrote the electronic control operating system

PET (Polyethylene terephthalate) extrusion line is a specialized production line used for manufacturing PET films and sheets. PET is a versatile thermoplastic polymer known for its excellent combination of mechanical, thermal, and chemical properties. It is widely used in industries such as packaging, textiles, automotive, and electrical.

Here are some key points about the PET extrusion line:

1. High-quality extrusion: The PET extrusion line is equipped with a high-performance extruder that ensures efficient and uniform melting and extrusion of the PET resin. This results in excellent film quality and consistency.

2. Precise temperature control: The extrusion line features an advanced temperature control system that allows precise adjustment of the heating and cooling zones. This ensures optimal processing conditions, resulting in films with consistent properties and thickness.

3. Multi-layer film capability: The PET extrusion line enables the production of multi-layer films with different functionalities. By incorporating multiple extruders and co-extrusion technology, it is possible to produce films with enhanced barrier properties, improved strength, or specialized surface properties.

4. Versatile film width and thickness: The PET extrusion line offers flexibility in producing films with various widths and thicknesses according to customer requirements. It can accommodate a wide range of film sizes, from thin gauge films used for packaging to thicker sheets used for industrial applications.

5. Efficient cooling and stretching system: The extrusion line includes a precise cooling and stretching system that ensures controlled cooling and precise stretching of the molten PET film to achieve the desired thickness and properties. This system helps maintain dimensional stability and control orientation.

6. Surface treatment options: The PET extrusion line can be equipped with additional surface treatment options such as corona treatment or plasma treatment. These treatments enhance the adhesion of inks, coatings, or adhesives to the PET film, enabling better printability, laminating, or bonding properties.

7. Inline quality control: The extrusion line incorporates inline monitoring and control systems for key parameters such as film thickness, transparency, and surface defects. This ensures consistent film quality and allows for real-time adjustments and troubleshooting during production.

8. Energy efficiency: The PET extrusion line is designed with energy-efficient components and technologies to minimize energy consumption and reduce operating costs. It utilizes advanced heat recovery systems and optimized heating and cooling processes.

9. Automation and advanced controls: The PET extrusion line is equipped with modern automation and control systems, including PLC touch screens and advanced control algorithms. This facilitates easy operation, monitoring, and adjustments for efficient production.

10. Sustainable production: PET extrusion lines can be designed to incorporate recycling or reclaiming systems, enabling the use of recycled PET material and contributing to a more sustainable production process.

The PET extrusion line offers reliable and efficient production of high-quality PET films and sheets, meeting the diverse needs of industries requiring PET-based materials.
