1.Polyurethane Injected Foam Cold Roll Forming Machine Introduction
FD discontinuous PU Sandwich Panel Production Line is a good choice with Economy investment, flexible size panel, high qualty
1.Machine is to make the sandwich panel with the color steel sheet or galvanized sheet and the core of polyurethane discontinuously.
2. The multi-layered laminator is consisted of the press and the rail stands. Two worktables move into the press and the other two stay on rail stands. Initially, put the top and the bottom sheets inside of mould frames and then seal, after that, feed the worktables into the press. When worktables inside the press moves out orderly, the other two feed in at the same time. Upon the finish of feeding, the press will close and slant at a angle, waiting for injecting PU raw materials from the PU mixing head into different panels. Meanwhile materials start foaming and curing. At this time, mould frames on worktables moved out for taking out the finished products, then to be ready for next production cycle.
3. The main laminator 2+2 produces PU sandwich panel with fixed length such as 6m, 9m, 12m, adjustable width less than 1.2m, different thickness from 50mm to 250mm by the closed molding frame
Technical Parameters: Length of panel: 6m,12m,15m Width of panel: 500-1250mm Thickness of panel: 40mm-250mm Speed of Production line: 8m/min ( frequency conversion to adjust speed ) Core Density (Kg/m2) :40-42 Thermal Conductivity (W/m°K) : 0.018 – 0.020 Tensile Strength ( KP a ) :300–500 Bending Strength (KP a) : 550–560 Shear Strength ( KP a ) :120–300 Modulus of Elasticity (M p a) : 3.0 – 8.5 Water Absorption : <2 (Volume change %) Water Vapor Transmission :1.8-3.8 (Perm-in) Stable Operating Temperature :-40to+50(°c) Capacity: One set of 6m PU Sandwich panel line is 288 sq.m. per day, 8 hours, so it is 72000 sq.m. yearly with 2500 days per year
One set of 12m PU sandwich panel line is 576 sq.m. per day, 8 hours. so it is 14400 sq.m. yearly, for 250 days per year. Production capacity of this production line: 3-8m/min. Panel width: 800-1000mm, panel thickness: 30-150mm. Total power: about 150kw
