PP honeycomb panel production equipment is specialized machinery for manufacturing polypropylene (PP) honeycomb panels, producing lightweight yet high-strength sheets with a honeycomb structure through extrusion molding. This equipment can produce three-layer sandwich-structured PP panels, with two thin surface layers and a honeycomb core in between, which can be designed as single or double-layer structures according to requirements.
PP honeycomb panels feature excellent properties such as light weight, high strength, environmental friendliness, shock absorption, cold resistance, sound insulation, thermal insulation, moisture resistance, and heat insulation. They are widely used in automotive manufacturing, architectural decoration, logistics packaging, transportation, and other fields.
1.Raw Material Preparation: PP raw materials undergo drying, crushing, and screening processes to ensure quality and uniformity.
2.Extrusion Molding: Pre-treated PP materials are heated to a molten state in an extruder and formed into a honeycomb structure through specially designed dies.
3.Hot Press Forming: The molten PP material is pressed in a hot press machine with heated rollers and molds to form a stable honeycomb structure under pressure.
4.Cooling and Solidification: The formed honeycomb panels are rapidly cooled and set through cooling systems (cooling rollers, water circulation systems).
5.Cutting and Finishing: High-precision cutting machines trim the panels to required sizes, while flattening and polishing machines improve surface quality.
6.Surface Treatment: Optional secondary processing equipment like laminating or fabric coating can be added to enhance functionality and aesthetics.
1.Extrusion System: Includes single or twin-screw extruders responsible for melting and preliminary forming of raw materials.
2.Composite Dies: Specially designed dies for honeycomb structure formation, determining the final product structure.
3.Hot Press Unit: Consists of heated rollers, heating devices, and pressure control systems to ensure stable honeycomb structure formation.
4.Cooling System: Composed of cooling rollers, water circulation systems, and temperature control devices for rapid and uniform cooling.
5.Traction and Cutting System: Precision servo traction and cutting machines ensure dimensional accuracy.
6.Automation Control System: PLC or computer control systems for precise adjustment of production parameters.

Main application:
1.Used for car trunk cover board, trunk clapboard, trunk carpet substrate, side wall decortation board, ceiling etc. interior place.
2.Used for manufacturing different kinds of high strength packing box.
PP honeycomb board through extrusion method made three layers sandwich board of one time forming, two sides is thin surface, middle is honeycomb structure; According to honeycomb structure can divide into single layer, double layer board. PP honeycomb board also can one time forming, coat fabric at two sides, leather, with light weight and high strength, non-toxic, environment, shake absorption and cold-resistant, soundproof& heat preservation, moistureproof& heat insulation etc. advantage.
