High Strength PP Honeycomb Board Extrusion Line - China Suppliers & Factory for Lightweight Plastic Boards

Discover the benefits of PP honeycomb boards, also referred to as plastic honeycomb boards, which are lightweight and high-strength materials made primarily from polypropylene. These innovative boards are designed to emulate the structure of a honeycomb, providing excellent durability and versatility for various applications.

Our PP honeycomb panel composite production line in China utilizes advanced PLC centralized control technology, ensuring a seamless manufacturing process. This includes automatic loading, three-layer co-extrusion (surface layer, honeycomb layer, and bottom layer), heating composite, calendering, and molding. The production process is completed with traction, tempering stress relief, natural cooling, trimming, width setting, and precise cutting to fixed lengths. Finally, our factory offers automatic stacking with an optional hydraulic stacker, making us one of the leading suppliers in the market.

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.

Frequently Asked Questions (FAQ)

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

The extrusion line is specifically designed for PP (polypropylene) material, which is used to form both the honeycomb core layer and the flat surface layers. PP offers excellent chemical resistance, recyclability, and mechanical strength suitable for a wide range of applications.

What board widths and thicknesses can the line produce?

Depending on the model selected, the line can produce boards ranging from 1200 mm to 2000 mm in width and 2 mm to 20 mm in thickness. The JWS75/75/75 model covers widths of 1200–1600 mm and thicknesses of 2–12 mm, while the JWS100/100/100 model supports widths up to 2000 mm and thicknesses up to 20 mm.

How does the thermal composite moulding process ensure product quality?

The advanced thermal composite moulding process independently forms the three layers — top surface, honeycomb core, and bottom surface — before bonding them as a single unit. This method precisely controls the thickness of each surface layer, ensures high flatness of the composite plate, and accurately manages the overall weight, resulting in superior appearance quality and processing performance.

What is the production capacity of the extrusion line?

The JWS75/75/75 model offers a capacity of 350–450 kg/h, while the JWS100/100/100 model delivers a higher output of 600–700 kg/h. The appropriate model can be selected based on your specific production volume requirements.

What industries are PP honeycomb boards suitable for?

PP honeycomb boards are widely used across multiple industries including automotive (interior and door panels), logistics and packaging (pallets and partitions), construction and interior design (partition and decorative panels), furniture manufacturing (lightweight panels and shelving), and industrial applications (protective and filler boards). Their lightweight and high-strength properties make them an excellent alternative to traditional wood, solid plastic, and metal panels.

How does the PLC pressure closed-loop control system benefit the production process?

The PLC-based pressure closed-loop control system works in conjunction with gear pumps to maintain stable melt pressure and ensure uniform material discharge into the die cavity. This results in consistent sheet thickness throughout the production run, minimising defects and material waste while supporting high-speed, reliable output.
