HDPE Sheet Production and Processing
Real‑scene view of the fully‑automatic extrusion production workshop. Adopting advanced process standards, it realizes seamless connection and quality monitoring from raw materials to finished products, ensuring the excellent performance of every board.
Implement precise digital control over the entire production process. From micron‑level proportioning of raw materials to rigorous inspection of finished products, every working procedure is refined to perfection, solely to produce high‑quality HDPE sheets with uniform thickness and stable performance.
01 Raw material mixing
Adopting a high‑precision batching system, high‑quality virgin HDPE resin is fully mixed with functional additives to ensure uniform and stable raw material composition.
02 melt extrusion
High‑temperature plasticization by the twin‑screw extruder combined with a precision flow‑channel die ensures stable melt pressure and lays a foundation for sheet forming.
03 Cooling and shaping
Three‑stage temperature‑controlled cooling water tank enables fast and uniform cooling, ensuring the plate thickness tolerance is kept within the precise range of ±0.1 mm.
04 Traction cutting
The variable‑frequency servo tractor delivers uniform feeding, working in conjunction with the fully‑automatic numerical‑control cutting machine for precise edge trimming and fixed‑length cutting. The finished products feature smooth, burr‑free edges and high dimensional accuracy.
05 Factory Quality Inspection
Each batch of products is tested for more than ten indicators including thickness, density, falling‑weight impact and heat‑deflection temperature. International standards are strictly implemented, and unqualified products are prohibited from leaving the factory.

HDPE Sheet Application Cases
On‑site shot: Large‑scale monolithic HDPE storage tanks custom‑manufactured in the factory. The integrally‑formed welding process ensures leak‑proof storage and corrosion resistance.
We not only provide high‑quality HDPE sheets, but also possess strong deep‑processing capabilities. We can customize various industrial finished products according to customers’ drawings, which are perfectly adapted to complex working conditions in chemical, environmental protection, warehousing and other fields.
Custom‑made large integral storage tanks
Utilizing the excellent chemical resistance of the plate materials, vertical/horizontal storage tanks are manufactured, which are widely applied for the safe storage of acid‑base liquids, drinking water and industrial wastewater. They feature great weather resistance and low maintenance costs.
Anti‑corrosion tank body and wear‑resistant lining plate
Custom‑manufactured chemical equipment such as pickling tanks and electroplating tanks feature resistance to acid and alkali corrosion. Wear‑resistant liners are provided for silos, chutes and dump truck bodies to reduce material adhesion and equipment wear.
Environmental‑protection water‑treatment components
Produce key components for sewage treatment plants such as scraper blades for sludge scrapers, mechanical bar screens, and baffle plates for biochemical tanks. These components feature excellent anti‑aging and anti‑corrosion properties and are suitable for harsh water environments.
HDPE Sheet Highlight Performance Features
Excellent low‑temperature resistance
Remains flexible at -70℃ and features excellent low‑temperature impact resistance. It is the preferred material for northern outdoor environments, cold storage facilities and cold‑chain low‑temperature working conditions, with overall performance far superior to PP and PVC sheets.
Food‑grade Safety · Non‑toxic & Eco‑friendly
Odorless and non‑toxic, it complies with FDA food‑contact standards and can be directly applied to scenarios with extremely high cleanliness requirements, such as food processing machinery, drinking water treatment equipment, and pharmaceutical and sanitary applications.
