High Strength PP Honeycomb Board Extrusion Line - Top China Suppliers and Factory for Lightweight Panels

PP honeycomb boards, also referred to as plastic honeycomb boards, are lightweight and high-strength materials made primarily from polypropylene. These innovative boards mimic the natural structure of honeycombs, providing exceptional durability and versatility for various applications.

Our PP honeycomb panel composite production line is designed with advanced PLC centralized control, allowing for seamless automation throughout the manufacturing process. This includes automatic loading, three-layer co-extrusion of the surface layer, honeycomb core, and bottom layer, followed by heating composite, calendering, and moulding. The process is completed with traction, tempering stress relief, natural cooling, trimming, width setting, fixed-length cutting, and automatic stacking, facilitated by an optional hydraulic stacker. As a leading China factory and supplier of PP honeycomb boards, we ensure high-quality production to meet diverse market needs.

Product Details

Performance & Features by Line Configuration

🔷 Honeycomb core layer: The core part, a honeycomb hexagonal lattice structure of holes made of PP. This structure is the key to the lightness and strength of the material.

🔷 Flat surface layer: Top and bottom, with PP flat sheets laminated to the honeycomb core by hot-melt technology to form a flat surface.

Market competition is becoming increasingly fierce, and high efficiency and environmental protection have become key considerations. With the bionic honeycomb structure, honeycomb panels achieve ultra-high strength with extremely light weight, which has significant advantages in reducing transport costs and improving material utilisation.

According to the width of the products and output requirements, single-screw or twin-screw extruder can be selected. The extruder is equipped with gear pumps and pressure closed-loop control through PLC, thus ensuring stable pressure and uniform discharge after the melt enters the die cavity to ensure consistent thickness of the sheet.

Roller temperature control and negative pressure system for honeycomb rollers. Each moulding roller is equipped with an independent temperature control system, which automatically adjusts the PID of the medium entering the roller, and can achieve the surface temperature of the roller at a constant temperature.

Frequently Asked Questions

What materials are compatible with the PP Honeycomb Board Extrusion Line?

The extrusion line is specifically designed for PP (polypropylene) material. Both the honeycomb core layer and the flat surface layers are produced using PP, making the final board fully recyclable and lightweight.

What are the available product width and thickness ranges?

Depending on the model selected, product widths range from 1200 mm to 2000 mm, and product thickness ranges from 2 mm to 20 mm. The JWS75/75/75 model supports widths of 1200–1600 mm, while the JWS100/100/100 model supports widths up to 2000 mm.

How does the line ensure consistent sheet thickness and quality?

The extruder is equipped with gear pumps and pressure closed-loop control via PLC, ensuring stable melt pressure and uniform discharge into the die cavity. Each moulding roller also features an independent PID temperature control system to maintain constant surface temperatures.

What is the key advantage of the three-layer independent moulding process?

The three-layer independent moulding process allows precise regulation of the upper and lower surface layer thicknesses before thermal composite bonding. This ensures high surface flatness, accurate overall weight control, and superior appearance quality and processing performance of the final board.

Which industries are PP honeycomb boards most suitable for?

PP honeycomb boards are widely used across automotive (interior and door panels), logistics and packaging (pallets and partitions), construction and interior design (partition and decorative panels), furniture manufacturing, and various industrial applications requiring lightweight yet strong panel solutions.

Can I choose between single-screw and twin-screw extruders?

Yes. Depending on your product width requirements and output capacity needs, you can select either a single-screw or twin-screw extruder configuration. This flexibility allows the line to be tailored to different production scales and efficiency targets.
