This production line 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 embossed 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 for making the ventilation duct 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 liquids 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 panel is edge-trimmed and, by an automatic tracking cutter, cut into segments according to the preset length.

1. Embossing machine unit: For embossing foil of 0.06 to 0.12mm thick. Max.loading coil: 2000kg.
2. Reaction Injection machine: To meter and mix two different liquid components in a given mixing ratio required by technical process. A chiller and a temperature controller are equipped to meet the temperature requirements of foaming liquid chemicals. We have both high and low pressure machines for user's optional use.
3. Foil decoiler: Double-coil or single coil loader for client's choice with loading coil weight up to 1000kg.
4. Double-belt laminator: Options of laminator's length: 12m, 18m, 24m, 30m or 36m; speed range: 2 to 8m/min. Materials of laminator's conveyor plank can be either steel or aluminum as per client's choice.
5. Hot-air circulator: Used to heat up laminator's belt conveyors in an optimal design of air circulation route which can heat to 60℃ from 20℃ in one hour. There are both furnace and electricty heaters equipped on the line while the funace can either use fuel oil or steam as heating energy depending on customer's choice.
6. Cross-cutter: With single or double pull broaches or disc-saw auto-tracking cutters for optional use. (Pls refer to the introduction on cutter series under matching equipment ).
7. Edge-trimming installation: There are both knife and disc-saw trimming installations for customer's coice.
8. Mobile injector: The user can choose either a hydralic motor or servo motor with crank as the driving system.
9. Pre-heating table: To heat to 40℃, temperature adjustable.
