Sandwich Panel Manufacturing Methods: Continuous And Discontinuous
Sandwich panel manufacturers use two technologies to manufacture panels: continuous and discontinuous. When all the utilized materials are processed together, it is known as a continuous process. The framed panel is sliced to the ideal length without stopping the line. When the materials are handled independently; this implies the facings are framed and slice to the ideal length and afterwards assembled in a press where the foam is infused, it is known as the discontinuous process.
The discontinuous process does not have a high level of productivity as compared to the continuous one. Today sandwich panel manufacturers utilize a discontinuous process for items with shapes that don't permit the continuous procedure, or when the generation rate required doesn't legitimize investment in a continuous process.
The average speed of the continuous line is around 14 meters per minute in production of panels of the thickness of about 40mm with metal facings. The production amount that is calculated is around 1,180,000 metres per year if anyone works over 220 days in a year. A discontinuous line with a twofold press 12 meters ...
... in length, under similar conditions, can arrive at a production of around 100,000 meters for each year when working one shift for every day. Also, the sandwich panel price in India is affordable.
Sandwich panels with both outside surfaces in sheet metal and an insulating core in polyurethane unbending foam, the principal segment begin with the sheet decoilers and proceeds with all the equipment for framing the two sheets into the ideal shape. The panel can be used as a sandwich panel walls or for rooftops. Sandwich panels with adaptable layers are not roll formed. The two surfaces of the final panels are flat. The surfaces are pre-warmed to the temperature required by the procedure (for the most part somewhere in the range of 40 and 65 C) and afterwards, the insulating material is prepared.
On account of polyurethane panels, the froth is created by beginning from the required components of chemicals metered and combined in the foaming machine. The subsequent fluid blend is uniformly dispersed over the lower metal sheet. The metallic facings, foam and conceivable side strips or gaskets are squeezed inside the twofold transport or continuous press. This machine needs to keep up the metal sheets separated at the ideal separation while the froth grows. You can see sandwich panel images to understand the process better.
Along these lines, thesandwich panel will have the ideal thickness and shape once the foam has extended and completely relieved. The most basic parameter to guarantee a decent outcome from the procedure is the temperature control of the chemical components, metal sheets and press territory. In the event that the insulating material is mineral wool or extended polystyrene, it is embedded and stuck to the metal sheets as sleeping cushions that have been sliced and formed to the correct thickness before insertion.
Temperature is again a basic parameter, this time for the response of the glue, for example for a good bond of the inward board to the outer layers. Subsequent to being shaped, the panel is sliced, cooled, stacked and wrapped with a plastic film. These last activities can be performed consequently or physically, contingent on the mechanization level that the client requires for their creation line. Sandwich panel price lists are available on the internet if you want to buy them. You can check it out from there.
