PP hollow sheet extrusion production line

PP hollow sheet is a lightweight hollow structural board made of Polypropylene as the main raw material through extrusion molding process. Its cross-section is lattice-shaped, with both high strength and lightweight characteristics, and is a new type of environmentally friendly material.

With the increasingly obvious trend of PP hollow sheet replacing corrugated cardboard in the packaging field, the market demand for PP hollow sheet has shown explosive growth.

Traditional 1220mm, 2100mm and other sized PP hollow sheet production lines are increasingly difficult to meet the market and customer requirements for products. Problems such as small width and low output not only occupy the production cost of the enterprise, but also limit the business expansion of the enterprise.JWELL Machinery took the lead in launching a 3500mm ultra-wide PP hollow sheet production line to greatly increase the product width, fill the market gap, and help the development of the industry.

Advantages of Jwell Ultra-wide PP hollow sheet extrusion production line

01 Advanced extrusion system

The newly designed screw structure ensures the plasticizing efficiency of the material and the stability of the output. Precise Siemens control system, screw speed can be automatically closed-loop control, to ensure good plasticization of raw materials and high output and stable extrusion.

02 Unique molding and cooling system

In the production of ultra-wide hollow sheets, extrusion molding and cooling shaping are the key to
whether the products are perfect. How to solve the problems of bending,deformation, arching,wave, and vertical rib bending in ultra-wide production? Jwell Machinery adopts extrusion molding and vacuum cooling shaping systems with proprietary technology.

Mold steel imported from Germany, Jwell Machinery's unique flow channel design. The mold is equipped with a highly active throttling device to make the material flow pressure uniform in the die; the upper and lower dies are flexible to adjust, ensuring the uniformity of the upper and lower wall thickness.

The aluminum vacuum setting plate and the surface are specially treated, which is more wear-resistant, light in weight and high in heat exchange efficiency. The vacuum system consists of two independent subsystems, each of which is equipped with an independent cooling water and a variable frequency vacuum adjustment system, so that the vacuum cooling can be flexibly adjusted according to the customer's production site.

03 Intelligent control system

The production line is controlled by Germany Siemens PLC and is equipped with a rich human-machine interface.All process parameters can be easily set and displayed through the touch screen, and the operation is simple and intuitive. The production line has intelligent closed-loop control, which automatically adjusts the extruder pressure and production line speed. In addition, the control system also has an automatic fault diagnosis function, which can promptly detect and solve problems that occur during the production process, greatly improving the stability and reliability of production,reducing manual intervention, and reducing production costs.

Characteristics and applications of PP hollow sheets

● Protection and cushioning: PP hollow sheet has excellent mechanical properties,high compressive strength, good toughness and impact resistance. Shockproof and impact-resistant,protecting products from damage during transportation.

● Environmental adaptability: waterproof and moisture-proof, corrosion-resistant, anti-aging,suitable for humid or chemical environments. Acid and alkali resistant, insect-proof, fumigation-free, with a lifespan of 4-10 times that of corrugated cardboard.

● Functional expansion: anti-static, flame retardant and other properties can be achieved by adding
masterbatch. Flexible processing, thickness and color can be adjusted according to customer needs, and the surface is easy to print and coat.

● Environmental protection and carbon reduction: The material is 100% recyclable, in line with the national carbon peaking and carbon neutrality goals, and the trend of replacing corrugated cardboard and injection molding boxes is significant.

Qo'llash sohalari

● Lightweight support: replace traditional boards (such as wood and metal plates) to reduce structural load;

● Industrial packaging: electronic component turnover boxes, food/beverage boxes, anti-static knife cards, precision instrument pads;

● Advertising and display: display racks, light boxes, billboards (easy to print on the surface);

● Transportation: automotive interior panels, logistics pallets;

● Agriculture and home: fruit and vegetable packaging boxes, furniture linings, children's products.
