​ What is Aluminuim Composite Panel?

Blog post   •   Aug 04, 2017 13:42 IST

Aluminium composite panel consists of two aluminium plates and a core between them. There are two types of cores available: polyethylene core (PE) and mineral core (FR). The face layer is covered with PVDF coating, which provide long term durability as well as resistance to colour fade and environmental conditions. Back side of each panel is covered with protective polyester layer.

Fields of application: - external finish of facade: for new or renewed buildings with ventilated hinged facade systems; - lining of balconies, cornices and canopies; - cladding for interior walls and ceilings; - linings of petrol stations, tunnels and pillars; - signboards, information and exposition stands; - different custom and non-standard objects.

Advantages of Aluminium Composite Panels are:

  • Light weight: with same stiffness, 4 mmpanel is 1.6 times lighter than aluminium sheet, and 3.3 times lighter than steel;
  • Stiffness and resistibility;
  • High weather resistance• temperature of use -50°C...+80°C;
  • Durability and high corrosion resistance;
  • Low linear expansion coefficient;
  • High acoustic and insulation features;
  • Processing convenience:panels are flexible, formable, easy-to-cut, drill and mill. Processing is possible both with manual or special CNC metalworking machinery.

Types of Composite panels processing

  • Cutting and milling: it is possible to use manual or stationery milling machinery. Milling tool material: high-speed steel or hard alloy metals. Maximum milling speed for high-speed steel: 3000 rpm with 25m/min feed; for milling tools and alloys: 5000 rpm with 30 m/min feed. CNC cutting and milling: high-speed cutters (single flute, upcut) are recommended with 10000-20000 rpm and 3-5 m/min feed.
  • Drilling is performed with ordinary twist drills provided for metal drilling. Drill material: high-speed steel. Cutting angle 100°-140°.
  • Bending: composite panels are bent by cold plastic bending applying different methods on rimming presses, folding and rounding machines. Minimal bending radius should 100 times exceed material thickness. To avoid damage of front surface or the panel, it is recommended to use 1-2 mm thick plastic filler sheets.
  • Welding is possible with hot-air welders using polyethylene cord. Welding speed 0.50-0.60 m/min.
