Sandwich Panel Production Systems

Steady and discontinuous panel manufacturing approaches
More than the last 50 several years, sandwich panels have advanced as a notably inexpensive indicates of construction. The combined materials are constantly two pores and skin layers (rigid metallic experiencing substance or versatile skins such as slim aluminum, paper or membranes, dependent on the application) and a core insulating substance.
There are fundamentally two panel producing technologies: steady and discontinuous. In the ongoing approach, all the utilised resources are processed with each other, and the totally shaped panel is minimize to the preferred length with no stopping the line. In the discontinuous process, the materials are processed independently this indicates the facings are shaped and reduce to the preferred size and then assembled collectively in a push in which the foam is injected.
The discontinuous process has a decrease stage of efficiency that can not be in comparison with that of the constant one. It is used right now for items with shapes that do not allow the steady process, or when the creation price required does not justify expenditure in a steady line.
A steady line has an common pace of about fourteen meters for every moment in manufacturing of medium panel thickness (forty-50 mm) with metallic facings. With one 8-hour change a working day over 220 times in a year, creation quantities to about 1,a hundred and eighty,000 meters for each 12 months, assuming an efficiency of eighty per cent. A discontinuous line with a double press twelve meters long, underneath the very same circumstances, can reach production of about one hundred,000 meters for each year when doing work 1 shift for each working day.
Ongoing panel production line
A normal ongoing line is manufactured up of the following 3 sections:
• exterior levels processing segment
• insulating content processing part
• panels dealing with segment
In a normal circumstance of a sandwich panel with equally exterior surfaces in sheet metal and an insulating core in polyurethane rigid foam, the 1st part begins with the sheet decoilers and carries on with all the equipment for forming the two sheets into the sought after shape. The panel could be a panel for walls or for roofs. Sandwich panels with versatile layers (aluminum, glass fiber sheets, asphalt paper) are not rollformed. Both surfaces of the closing panels are fully flat. The surfaces are pre-heated to the temperature essential by the process (typically between forty and 65 C) and then the insulating materials is geared up.
In the scenario of polyurethane (PU-PIR) panels, the foam is generated by commencing from the required chemical components metered and combined together in the foaming device. The ensuing liquid mixture is evenly dispersed above the decrease steel sheet. The metallic facings, foam and feasible aspect strips or gaskets are pressed inside of the double conveyor or constant push. This equipment has to sustain the metal sheets divided at the desired distance while the foam expands.
In this way, the panel will have the preferred thickness and condition when the foam has expanded and totally healed. The most crucial parameter to ensure a very good consequence from the method is the temperature manage of the chemical factors, metallic sheets and press area. If the insulating materials is mineral wool or expanded polystyrene, it is inserted and glued to the metal sheets in the form of mattresses that have been minimize and formed to the right thickness just before insertion.
Temperature is once again a vital parameter, this time for the response of the glue, i.e. for very good adhesion of the inner board to the exterior levels. Following being shaped, the panel is lower, cooled, stacked and wrapped with a plastic movie. These previous operations can be executed automatically or manually, depending upon the automation degree that the buyer needs for their generation line.
