Double Screw PET Plastic Sheet Extruder Line Making Machine

Description:

The PET parallel twin screw sheet extrusion line for PET sheet is equipped with degassing system, and no need drying and crystallizing unit. The extrusion line has the properties of low energy consumption, simple production process and easy maintenance. The segmented screw structure can reduce the viscosity loss of PET resin, the symmetrical and thin-wall calender roller highten the cooling effect and improve the capacity and sheet quality. Multi components dosing feeder can control the percentage of virgin material, recycling material and master batch precisely, the sheet is widely used for thermoforming packaging industry.

1) Plastic sheet making machine has High capacity.
2) Energy saving: 20% energy saving than normal machines.
3) Four self-designed major core technology of sheet extruder: extrusion system, die, roller, distributor. They are all invented and designed by ourselves. The core technology has many testing points and adopts electrical integration of double protection.
4) The operation fully reflects the man-machine engineering principle, it can make the function more entirely and the operation more simple.
5) Only the tablet machine independently walking, avoid the interference from other power to influence the stability of the tabletting sheet.
6) The plasticizing effect of the sheet is very good. After the sheet formed and walking in curved line, it can make sure the stability of the sheet stock.
7) The heating system is controlled by high-grade china heater, stainless heater, inner-storing type single heating pipe and precision temperature-controlling die mould, is exact in controlling temperature, quickly in heating, good in keeping temperature, long life and save time and energy.

(1) If customers require multilayer PET sheets, the number of extruders needs to be increased. Three-layer PET sheet needs at least two extruders, which can produce PET sheets with ABA structure; it can also be customized according to customer requirements. 5-layer PET sheet, if the sheet structure is ABCBA, then 3 extruders are required, and a distributor is required in front of the mold to adjust the distribution ratio;

(2) According to the purpose of PET sheet, the auxiliary equipment equipped on the PET production line is different. If customers use PET sheets to make blister products, such as plastic electronic product packaging, parts packaging, fast food boxes, plastic cups, etc., then the production line needs to be equipped with silicone oil coating and drying equipment, which is beneficial to PET sheets In the later stage, it is molded on the blister machine and demolded; if the PET sheet produced by the customer is not used for thermoforming, this part can be removed, which can also save the customer the equipment purchase cost; if the PET sheet produced by the customer needs to be used for post-printing Or it can be combined with other materials, then a corona machine needs to be added to the PET sheet equipment. The corona machine can treat the surface of the PET sheet; if the surface of the PET sheet produced by the customer needs to be smooth and bright, it can be on the PET sheet line Increase the upper and lower laminating devices to cover both the front and back sides of the PET sheet with a protective film;

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.
