Main Features:
1. The SP-9 Z Lock Colored Steel Sandwich Panel production line mainly consists of the Corrugated Roll Forming Machine and the Colored Steel Sandwich Panel Laminator. with this machine colored steel wall panels or colored steel roof panel can be produced in just one-time, and the Corrugated Roll Forming Machine and the Sandwich Panel Laminator can work independently. The whole production line of the Corrugated Roll Forming Machine consists of the uncoiler, cold-bending roll forming machine, cutting device, whereas the Sandwich Panel Laminator consists of the uncoiler for colored steel, EPS block, or mineral wool panel, shallow wave for wall panels pressing device, extruding system, mixed-glue spraying, heating and pressurizing system, sandwich, flat curling, edge rolling, edge-turnover, grooving, edge-trimming device, pneumatic clamping device, automatic plastic film coating device, automatic cutting, product stacker;
2. The transmission of the sandwich panel laminator uses worm-worm gear transmission system, ensuring that lamination speed is stable and lamination is uniform;
3. The sandwich panel laminator uses the frequency regulator to automatically cut according to the pre-set sandwich panel length;
4. The sandwich panel laminator uses rubber-coated roller type laminator to protect the color paint on the colored steel as well as during the pressurizing of the sandwich panel;
5. The sandwich panel laminator has a high quality and thick wall rectangular steel welding method, and to get rid of the rust, polishing, smoothing and aging treament;
6. The appropriate colored steel sheet: Width=1000-1200mm (the size of the length of panel is without imitation), thickness= 0.2-0.8mm;
7. The recommended core materials for Sandwich Panel: EPS Panels, PU Panels, XPS Panels and Mineral Wool Panels;
8. Production Capacity of this Production Line: 5-7m/min; Total Length of this Production Line: 60m; Net Weight of this Production Line: About 30tons; Total Power Supply of this Production Line: 60kw; Thickness of the finished Panel produced by this production line: 50-250mm.
