What is PP hollow panel sheet ?
PP hollow grid board is a lightweight hollow structural board made primarily of polypropylene through an extrusion molding process. Its cross-section is grid-like, combining high strength and lightweight characteristics, and it belongs to the 411 new environmentally friendly material category.
With the increasing trend of hollow grid boards replacing corrugated cardboard in the packaging industry, the market demand for PP grid boards has exploded. Traditional 1220mm and 2100mm grid board production lines are increasingly unable to meet market and customer requirements. Problems such as small width and low output not only consume production costs for enterprises but also limit business expansion. JWELL Machinery has pioneered the launch of a 3500mm ultra-wide PP hollow sheet production line, significantly increasing product width, filling a market gap, and contributing to industry development.
What is the advantages of JWELL pp hollow sheet extrusion line ?
Advanced Extrusion System
The newly designed screw structure ensures efficient material plasticization and stable output. A precise Siemens control system enables automatic closed-loop control of the screw speed, ensuring good plasticization of raw materials and stable high-volume extrusion.
Unique Forming and Cooling System
In the production of ultra-wide hollow square panels, extrusion molding and cooling are crucial for product perfection. How to solve problems such as bending deformation, arching, wavy lines, and vertical rib bending in ultra-wide panel production? JWELL Machinery utilizes proprietary extrusion dies and a vacuum cooling and shaping system.
Using imported German die steel and JWELL Machinery's unique flow channel design, the die features a highly flexible throttling device, ensuring uniform pressure distribution of the material flow at the die opening; the flexible adjustment of the upper and lower dies ensures uniform wall thickness.
Intelligent Control System
The production line is programmed and controlled by Siemens PLC from Germany, equipped with a comprehensive human-machine interface. All process parameters can be easily set and displayed via the touch screen, making operation simple and intuitive. The production line features intelligent closed-loop control, automatically adjusting extruder pressure and production line speed. Furthermore, the control system has an automatic fault diagnosis function, enabling timely detection and resolution of problems during production, greatly improving production stability and reliability, reducing manual intervention, and lowering production costs.
What is the characteristics and applications of pp grid hollow panel ?
* Protection and Cushioning: PP grating possesses excellent mechanical properties, high compressive strength, good toughness, and impact resistance. It provides shock absorption and impact resistance, protecting products from damage during transportation.
* Environmental Adaptability: Waterproof, moisture-proof, corrosion-resistant, and anti-aging, suitable for humid or chemical environments. Acid and alkali resistant, insect-proof, fumigation-free, and with a lifespan 4-10 times that of corrugated cardboard.
* Functional Expansion: By adding masterbatch, antistatic and flame-retardant properties can be achieved. Flexible processing; thickness and color can be adjusted according to customer needs; easy-to-print and laminated surfaces.
* Environmental Protection and Carbon Reduction: The material is 100% recyclable, aligning with national "dual carbon" targets, and showing a significant trend of replacing corrugated cardboard and injection-molded boxes.
