PET/RPET/APET/CPET/PETG Sheet Extrusion Line
In the modern world, plastic products have become an integral part of our lives. They are used in a wide range of applications, from food packaging to automotive parts manufacturing. However, the process of manufacturing plastic products requires specialized equipment. One of these is the PET/RPET/APET/CPET/PETG sheet extrusion line.
Extrusion is a process in which plastic material is pressed through a special mold to obtain the desired shape and size. This process is used to produce various types of plastic sheets, including PET (polyethylene terephthalate), RPET (recycled polyethylene terephthalate), APET (amorphous polyethylene terephthalate), CPET (crystalline polyethylene terephthalate) and PETG (polyethylene terephthalate glycol).
The PET/RPET/APET/CPET/PETG sheet extrusion line is a complete equipment that includes various devices such as extruder, calendering machine, cooling and cutting device, and finished product winding device.
The extruder is the main device in the extrusion line. It consists of a cylinder, inside of which there is a screw rotated by an electric motor. The plastic material is fed into an extruder, where it is converted into a viscous mass under the influence of heat and pressure. This mass is then squeezed through the mold, giving it the desired shape.
Calendering machine is used to give the plastic sheet the desired thickness and smoothness. It consists of several shafts, between which a plastic sheet passes. As it passes through the rollers, the sheet becomes thinner and smoother.
The cooling and cutting device is used to cool the hot plastic sheet and then cut it into individual sheets of the desired size.
The finished product winder is used to wind finished plastic sheets into rolls for subsequent transportation and storage.
The PET/RPET/APET/CPET/PETG sheet extrusion line allows you to produce high quality plastic sheets with minimal time and resources. It has high performance, reliability and durability, which makes it an indispensable equipment in any production of plastic products.
In conclusion, I would like to note that the development of technologies in the production of plastic products opens up new opportunities for improving the quality of products and reducing the costs of their production. The use of PET/RPET/APET/CPET/PETG sheet extrusion line is one of the important steps in this direction.
PET is usually flake, used to produce PET sheets, widely used for packaging food, medicine, electronics, etc.

The feedblock controls the thickness of the layer, which can be layered into AB, ABA, ABC, ABCBA.
Calender roll system for calibrating sheet thickness. Each axis is equipped with a servo motor. Adjust the gap between the shafts using the PLC system. Depending on the sheet being produced, a 3 or 5 roll calender can be used.
The shaft is chrome-plated and polished.
Online thickness measurement scans sheet thickness efficiently and automatically.
Edge cutter allows you to move the cut sheet back to the extruder hopper
Cooling of roller conveyors requires cooling of the plates.
Film storage sheet accumulator helps store films while changing rolls
A four position winder is used to wind the sheet into the drum.
