A PP honeycomb board extrusion line is a specialized production system that manufactures lightweight three-layer sandwich panels with a honeycomb-structured core. The line uses a continuous single-step extrusion process to form two thin outer surface layers with a polypropylene honeycomb core in between. JWELL’s PP honeycomb board extrusion lines are available in two model series — JWS75/75/75 (width 1,200–1,600 mm, capacity 350–450 kg/h) and JWS100/100/100 (width 1,200–2,000 mm, capacity 600–700 kg/h) — producing boards with thicknesses from 2 mm to 20 mm for automotive, packaging, and building insulation applications.
PP honeycomb boards are primarily used in three sectors: automotive interiors (trunk cover boards, trunk clapboards, trunk carpet substrates, sidewall decoration panels, and ceiling panels), packaging (high-strength lightweight packing boxes for logistics and shipping), and building and construction (soundproofing, heat insulation, and thermal preservation panels). In the automotive industry, PP honeycomb boards are increasingly replacing traditional materials due to their superior strength-to-weight ratio and NVH (noise, vibration, and harshness) performance.
PP honeycomb boards feature a hexagonal honeycomb core structure with 360-degree interconnected cells, providing uniform stress distribution in all directions. Ordinary PP hollow boards use a vertical strip structure with limited directional strength. Compared to hollow boards, PP honeycomb boards offer significantly higher impact resistance, bending strength, load-bearing capacity, and cargo protection. The honeycomb structure also provides better sound insulation and thermal insulation, making it the preferred choice for demanding automotive and packaging applications.
JWELL offers two model series for PP honeycomb board production. The JWS75/75/75 produces boards 1,200–1,600 mm wide and 2–12 mm thick at 350–450 kg/h. The larger JWS100/100/100 produces boards 1,200–2,000 mm wide and 2–20 mm thick at 600–700 kg/h. Both models feature multi-screw extruders with full intermeshing engagement, deep screw channels, exhaust systems, Siemens PLC control, and servo motor drives. The lines can also apply fabric or leather coatings on both sides during the extrusion process in a single step.
Yes, JWELL’s PP honeycomb board extrusion lines are capable of applying fabric or leather coatings on both surfaces of the board simultaneously during the extrusion process. This single-step lamination eliminates the need for secondary surface treatment, reduces production cost, and improves bonding quality between the PP core and the surface material. This capability is particularly valuable for automotive interior applications where decorative finishes such as cloth, felt, or synthetic leather are required on trunk panels, sidewall trims, and ceiling boards.
PP honeycomb boards are widely adopted in automotive interiors because they offer an optimal combination of properties required by vehicle manufacturers: lightweight construction (reducing overall vehicle weight and improving fuel efficiency), high rigidity and impact resistance (protecting cargo and passengers), excellent sound insulation (reducing cabin noise), thermal insulation (maintaining comfortable interior temperatures), moisture resistance (preventing mold and degradation), and 100% recyclability. These boards meet automotive industry standards and are used by OEMs for trunk covers, parcel shelves, door panels, floor substrates, and headliners.
JWELL’s PP honeycomb board extrusion lines use a multi-screw extruder configuration with full intermeshing engagement and deep screw channel design. The multi-screw system provides superior mixing and melt homogeneity compared to single-screw designs, which is critical for producing uniform honeycomb cell structures. Key components include a screen changer, metering pump (Maag or Nordson brand), precision T-die (Jc-Times or Jwell brand), calender rollers made of alloy steel, and an online thickness gauge for real-time quality monitoring. The entire system is controlled by a Siemens PLC with servo motor drives.
JWELL’s PP honeycomb board extrusion lines offer two production capacity ranges. The JWS75/75/75 model delivers 350–450 kg/h of output, suitable for medium-scale production. The JWS100/100/100 model achieves 600–700 kg/h for high-volume manufacturing. Production capacity depends on board thickness and width — thinner and narrower boards run at higher line speeds. JWELL provides technical consultation to match the appropriate model to the customer’s specific production volume and product dimension requirements.
Selecting the right JWELL PP honeycomb board extrusion line depends on four factors: (1) Board dimensions — determine the required width (1,200–2,000 mm) and thickness range (2–20 mm) based on your target products; (2) Production volume — match output requirements to the JWS75/75/75 (350–450 kg/h) or JWS100/100/100 (600–700 kg/h) model; (3) Surface finishing — consider whether fabric or leather lamination is needed during extrusion; (4) Application sector — automotive interior, packaging, or building insulation may require different board configurations and quality standards. JWELL’s engineering team provides customized line configurations and factory acceptance testing.
JWELL Machinery provides comprehensive support for PP honeycomb board extrusion lines including one-year warranty, on-site installation and commissioning at the customer’s factory, operator training programs, and lifetime maintenance service. Technical engineers can be dispatched to the customer’s facility within 24–48 hours, or customers may send engineers to JWELL’s factory for hands-on training. With 8 manufacturing bases, 3,000+ employees, and 20+ subsidiaries worldwide, JWELL offers global spare parts availability through international brand components (Siemens, Schneider, ABB) and maintains offices in Vietnam, Turkey, Thailand, Brazil, and Canada.
