Product Description
The Jinwei PET sheet extrusion line is a strategically designed, continuously improved model. The company employs a special‑price sales strategy to maintain market share, offering competitive pricing for equivalent specifications while pursuing ongoing technological upgrades. It can process materials such as APET, PETG, and RPET.
Classification and Introduction of PET Sheet Extrusion Production Lines:
1. PET Sheet Single-Screw Extrusion Line: APET, PETG, and CPET sheet single-screw extrusion lines represent a mature, production‑stable solution. These lines typically employ either a single‑extruder or a twin‑extruder co‑extrusion configuration. Jinwei’er has introduced new technologies that enhance the overall performance of this equipment by 30%.
2. PET Sheet Single-Screw Extrusion Line with Degassing: This model requires only crystallization of the PET resin, eliminating the need for drying. Its advantages include low energy consumption, a simple process, convenient equipment maintenance, and the ability to produce thermoformed cups with a depth of 18 cm.
3. PET Sheet Twin-Screw Extrusion Line with Degassing (No Crystallization or Drying Required): Jinweier’s crystallization‑ and drying‑free degassing PET sheet extrusion line boasts low energy consumption and high efficiency. This model represents a continuously refined and upgraded product, featuring a major technological upgrade to its core vacuum system: the original Roots–water‑ring pump configuration has been replaced with a Roots–vane pump setup, enabling vacuum levels as low as ≤10 Pa. Additionally, the use of a thin‑walled roller set made from PET‑specific alloy steel significantly enhances cooling performance, thereby increasing production capacity and improving the toughness and transparency of the finished products. Jinweier’s independently programmed operating system ensures user‑friendly operation and ease of use.
4. PET Sheet Planetary Multi-Screw Extrusion Line (No Crystallization Drying Required): Utilizing a planetary screw extruder as the main unit, this line significantly increases the contact area between the material and the air. Paired with Jinwei’s newly developed vacuum‑extraction system, it meets the demands of customers seeking high‑volume production of premium‑quality sheets.

Using co-extrusion technology with multiple extruders, we produce multilayer co-extruded PET sheets, such as APET/PETG, PETG/APET/PETG, and APET/RPET/APET laminates. These materials are widely used in thermoforming, printing, metal‑part packaging, and gift‑folded packaging, among other applications.
* Equipped with a precision dispenser, ensuring uniform layering; the proportion of each layer is adjustable and displayed digitally.
* The inclined tablet‑pressing structure makes operation and maintenance more convenient.
* Independent drive for the roller, with closed-loop control of linear speed synchronized to the extruder’s rotational speed, and a full servo system.
* The entire machine is controlled by a Siemens PLC, enabling automated control of parameter settings, data processing and feedback, alarm functions, and more.
* The operating procedures and control system were independently developed by Jinwei'er.
