3.2-meter-wide sheet production line

1. Structure of the PE Sheet Production Line: The production line consists of a single-screw plastic extruder, a sheet die head, a three-roll calender, a haul-off unit, and other components. Our factory’s plastic sheet production line features a compact design and excellent performance. The screw and barrel are optimized in design and manufactured from alloy steel, ensuring uniform plasticization, stable extrusion output, high productivity, and long service life. The main machine’s barrel is equipped with superior heating and cooling systems, along with precise electronic temperature control. 2. Production Process of the PE Sheet Production Line: (1) Processing of Recycled Materials: Recycled materials often have complex compositions. They are first manually sorted by type—such as PP, HDPE, LDPE, PVC—and then crushed, washed, and dried before being stored for use. (2) Regeneration of Recycled Materials: Depending on specific formulation requirements, fillers and additives are blended into the recycled material, which is then pelletized using a single-screw extruder for later use. (3) Template Manufacturing: Different regenerated materials are processed according to their respective procedures to produce templates tailored to specific applications. (4) Analysis and Quality Control: Accurate analysis of the properties of both recycled and regenerated materials is essential for determining appropriate processing conditions. Before leaving the factory, all templates undergo rigorous quality inspections. 3. Characteristics of Plastic Templates Produced on the PE Sheet Production Line: (1) Excellent Water Resistance: Even when fully immersed in water for several days, these templates do not deform due to moisture absorption and remain free from rot or rust. (2) Non‑Adhesive Properties: They do not bond with cement, making demolding easy and preventing deformation caused by cement adhesion. (3) High Construction Efficiency: Structures built using these templates exhibit smooth, even surfaces, eliminating the need for secondary finishing work. (4) Streamlined Processes and Increased Productivity: During template fabrication, surface treatments can be applied to create desired wall patterns, further enhancing efficiency. (5) Lightweight and Easy to Handle: Their light weight facilitates convenient transportation and installation. (6) Long Service Life: These plastic construction templates can be reused multiple times. Damaged templates can be ground down and reprocessed into new ones, conserving resources and aligning with “green industry” principles. (7) Superior Insulation: Their thermal insulation properties help shorten construction timelines. (8) Versatile Processing Options: These templates can be treated with wood-based coatings or welded, allowing flexible on-site secondary processing.

3.2-meter-wide sheet production line

1. Structure of the PE sheet production line: The unit consists of a single-screw plastic extruder, a sheet die head, a three-roll calender, a haul-off unit, and other components. Our plant’s plastic sheet production line features a compact design and excellent performance. The screw and barrel are optimally designed and manufactured from alloy steel, ensuring uniform plasticization, stable extrusion output, high productivity, and long service life. The main machine’s barrel is equipped with superior heating and cooling systems, along with precision electronic temperature control.

2. Production process of the PE sheet extrusion line:

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

(2) The recycling process for reclaimed materials. Depending on the specific formulation requirements, fillers and additives are incorporated into the recycled material, which is then 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) Analysis and quality control procedures. Accurate analysis of the properties of recycled and reprocessed materials is essential for correctly determining the processing conditions for the next stage. Before leaving the factory, 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 warp due to moisture, nor will it rot or rust.

(2) It is non‑adhesive to cement, ensuring easy demolding after construction and preventing deformation caused by cement adhesion.

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

(4) It reduces the number of construction steps and enhances work 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) It can be treated by adding wood and is also weldable, allowing for flexible secondary processing on the construction site.
