2018-12-19

1. Structure of the PE sheet production line: The unit consists of a single-screw plastic extruder, an automatic vacuum feeder, a dehumidifying and drying hopper, a sheet die head, a three-roll calender, a roller‑supported cooling system, a haul‑off unit, a cutter, a roller conveyor, and other components. Our plant’s plastic sheet production line features a compact design; the screw and barrel have been optimized and manufactured from high‑performance alloy steel, ensuring uniform plasticization, stable extrusion output, high productivity, and long service life. The main machine’s barrel is equipped with advanced heating and water‑cooling systems, with temperature controlled by precision electronic instruments. 2.

Our plant’s plastic sheet production line features a compact design; its screws and barrels have been optimized and manufactured from high‑performance alloy steel, ensuring uniform plasticization, stable extrusion output, high productivity, and extended service life. The main machine’s barrel is equipped with superior heating and water‑cooling systems, with temperature controlled by precision electronic instrumentation.

2. Production process of the PE sheet extrusion line:

(1) Processing of recycled materials: Due to the complex composition of the recovered materials, they are first manually sorted by material type—such as PP, HDPE, LDPE, and PVC—then crushed, washed, and dried before being set aside for further use.

(2) In the recycling process, various fillers and additives are incorporated into the recycled material according to the specific formulation requirements, and the resulting compound is pelletized using a single-screw extruder for subsequent use.

(3) Template manufacturing process: Different recycled materials shall be processed according to their respective procedures to produce the required templates.

(4) The analysis and quality-control procedures, which enable accurate characterization of the properties of recycled and reprocessed materials, are essential for properly determining the processing conditions for the next stage. Prior to shipment, molds must also undergo product quality inspection.

3. Characteristics of plastic formwork manufactured on a PE sheet production line:

(1) Excellent water resistance. Even when fully immersed in water for several days, it will not deform due to moisture. It is resistant to rot and rust.

(2) It exhibits no affinity or adhesion to cement, allowing for easy demolding after construction and preventing deformation caused by cement bonding.

(3) High construction efficiency and excellent results. Structures built using this method feature smooth, even surfaces that require no secondary finishing.

(4) It reduces the number of processing steps and enhances construction efficiency. Additionally, during template fabrication, the template surface can be pre-treated to achieve the desired wall‑surface pattern.

(5) Lightweight and easy to install;

(6) The plastic construction formwork produced on the production line boasts a long service life and can be reused numerous times. Even damaged plastic formwork can be crushed and reprocessed into new formwork, thereby conserving resources and meeting the requirements of “green industry.”

(7) Excellent thermal insulation, which helps shorten the construction schedule;

(8) Various treatments can be applied by adding wood, and welding is also possible; therefore, secondary processing can be carried out flexibly on the construction site.
