PP hollow sheet is a lightweight hollow structural board made of Polypropylene as the mainraw material through extrusion molding process. its cross-section is lattice-shaped, with bothhigh strength and lightweight characteristics, and is a new type of environmentally friendlymaterial.
With the increasingly obvious trend of Pp hollow sheet replacing corrugated cardboard inthe 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 increasinglydificult to meet the market and customer requirements for products, Problems such as smalwidth and low output not only occupy the production cost of the enterprise, but also limit thebusiness expansion of the enterprise. JWELl Machinery took the lead in launching a 3500mmultra-wide Pp hollow sheet production line to greatly increase the product width, fill the marketgap,and help the development of the industry.
1.Advanced extrusion system
The newly designed screw structure ensures the plasticizing efficiency of the material and the stability ofthe output. Precise Siemens control system, screw speed can be automatically closed-loop control, to ensuregood plasticization ofraw materials and high output and stable extrusion.
2.Unique molding and cooling system
In the production of ultra-wide hollow sheets, extrusion molding and cooling shaping are the key towhether the products are perfect. How to solve the problems of bending, deformation, arching, wave, andvertical rib bending in ultra-wide production? Jwell Machinery adopts extrusion molding and vacuum coolingshaping systems with proprietary technology.
Mold steelimported from Germany, JwellMachinery's unigue flow channel design. The mold is equippecwith a highly active throttling, device to make the material flow pressure uniform in the die, the upper ancower 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-resistantlight in weight and high in heat exchange efficiency. The vacuum system consists of two independentsubsystems, each of which is equipped with an independent cooling water and a variable freguency vacuumadjustment system, so that the vacuum cooling can be flexibly adjusted according to the customer's productionsite.
3.Intelligent control system
The production line is controlled by Germany Siemens PLC and is equipped with a rich human-machineinterface. All process parameters can be easily set and displaved through the touch screen, and the operationis simple and intuitive. The production line has intelligent closed-loop control, which automatically adjusts theextruder pressure and production line speed. In addition, the control system also has an automatic fauldiagnosis function, which can promptly detect and solve problems that occur during the production processgreatly improving the stability and reliability of production, reducing manual intervention, and reducingproduction costs.
-Protection and cushioning: pp hollow sheet has excellent mechanical properties, high compressive strengthgood toughness and impact resistance. Shockproof and impact-resistant, protecting products from damageduring transportation.
-Environmental adaptability: waterproof and moisture-proof, corrosion-resistant, anti-aging, suitable forhumid or chemical environments. Acid and alkali resistant, insect-proof, fumigation-free, with a lifespan of4-10times that of corrugated cardboard
-Functionalexpansion: anti-static, flame retardant and other properties can be achieved by addingmasterbatch. flexible processing, thickness and color can be adjusted according to customer needs, and thesurface is easy to print and coat;
-Environmental protection and carbon reduction: The material is 100% recyclable, in line with the nationacarbon peaking and carbon neutrality goals, and the trend of replacing corrugated cardboard and injectiormolding boxes is significant.
Application Areas:
- 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 cardsprecision 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.
