produce line of sandwich panel with aluminum foil

Produce line of sandwich panelwith aluminum foil facings is a kind of specialized equipment for producing laminated panels with the middle layer of anti-combustion polyurethane or polyisocyanurate or phenolic polyfoam and with aluminum foil as the top and bottom face layers. The laminated panel is between 20 and 30 mm in thickness, 1200mm in width, length determined by the customer. The panel is mainly used as the ventilation pipe for central air-conditioners. Different insulating panels with other soft facing layers could also be produced on the line. The operation principle of this line is as follows: raw materials of rigid-foam plastic are delivered into the mixing head through the metering pump on the injection machine and then injected onto the bottom facing sheet going to conveyors along with the top superficial sheet. Between the upper and lower conveyors, the liquid materials are hardened into shape, after which the laminated sheet is edge-trimmed and, by an automatic tracking cutting mechanism, cut into segments according to the preset length. The production line has already passed the hi-and neo-tech product identification carried out by the Economic and Trade Commission of Jiangsu Province and Jiangsu Science and Technology Department, being evaluated as one of the first-batch high and new products of Jiangsu Province PROCESS FLOW SITE OF PLAN(Click on names of equipment to see detail introduction) MAIN TECHNICAL PARAMETERS Specification of produced panel1200 mm×2030 mm (Width×Thickness), Length on request Linear speed of production 25 m/min Maximum embossing speed15 m/min Agitating speed4500 r/min Reciprocating times of injection head per minute60 Maximum temperature of hot-air circulating70 Laminating length of laminator18 m Maximum clearance between conveyors 250 mm Total power (KVA) 85125 Overall external dimensions40340×5365×3636 mm (Length×Width×Height) Eexternal dimensions of embossing machine unit 7050×3200×1600 mm (Length×Width×Height) Weight ≈33 tons
