ZHONGJI SANDWICH PANEL PRODUCTION LINE PU Sandwich Panel Production Line 01 PU Foaming Machine & Tank Station Uncoiler for lower and upper facing. Uncoiler units including coil loader, pressing rollers, band edge control system, band delivery drivers, shearing, band connecting stations, looping station, delivery roller table. Advantage : Time-saving(and therefore also cost-saving) continuous coil and band exchange standstill of the facility. PU Foaming Machine Axial piston, series piston, single piston and diaphragm pumps to process the different components. Design of the entire "Wet part" complying with the environmental requirement. Roll Forming Pentane metering machine Roll Forming machines to shape surfaces and edges of the wall, roof and sectional door elements. Advantage : Good accessibility and minimum profile exchange times by the serial installation of the profiling machines. Driving the profiling tool sets by means of DC motor including electronic control guarantees the synchronous inlet of the two metal widths into Double Conveyor facility without tension or thrust. Potal & PU Foaming Foaming Potal to apply the raw material mixture by means of the oscillating mixhead. Variocontrol drive including intergrated mass balance, longitudinal travelling mechanism for highly accurate adaptation to the production speed, adjustment for the mixhead as to height, exhaustion system for reaction gas.
