Honeycomb panels are made by bonding two face panels with a honeycomb core material using adhesives. For example, aluminum honeycomb panels are first pressed with an aluminum honeycomb core, then coated with adhesive and bonded to an aluminum sheet.
They are then shaped through cold pressing and cutting processes, resulting in lightweight, high-strength panels with heat and sound insulation properties.
The honeycomb panel manufacturing process involves several key steps: First, polypropylene (PP) resin granules are selected as the raw material. After being melted and plasticized at high temperatures using an extruder, they are extruded through a special mold to form a honeycomb structure.
During production, temperature, pressure, and speed must be precisely controlled to ensure structural stability. After cooling and shaping, they are cut and surface-treated. Finally, they undergo rigorous testing for appearance, strength, and other indicators before leaving the factory.
