Pu Sandwich Panel Production Line - 24m Double Conveyor FAQ: Integration, Spare Parts and Maintenance Questions

The published configuration includes upper and lower coil cars and hydraulic uncoilers, top and bottom roll-forming equipment, protective-film coating devices, grooving rolls, a bottom-side corona system, steel-facing pre-heating, a four-component high-pressure PU foaming machine, tanks and feed pumps, a foaming portal, pentane gas detection and ventilation equipment, a 24m double belt conveyor with heating and automatic temperature control, side guides, side blocks, a cross cutter, and an electric control system with synchronization.

The line is configured for Roof 4-rib, Cold Room, and Boltless hidden-fix panel profiles. The panel thickness range is 35–150 mm, the maximum panel length is 15,000 mm, and the line-speed range is 0–8 m/min for that product configuration.

Confirm the incoming electrical supply, workshop layout, material-handling route, ventilation arrangement, and any items identified as buyer scope. The published description identifies the water chiller as buyer scope and also identifies the ducting for gas suction to the outside as buyer scope. For the cross cutter, the housing and dust collector are also marked as buyer scope.

The line uses pre-painted steel sheet, with the published parameter sheet listing maximum coil weight of 10 tons, sheet thickness of 0.4–0.7 mm, and coil widths of 1070, 1200, or 1220 mm. It lists 380 V or 440 V at 50 Hz as the power-source options. These values are configuration data, not a substitute for a site survey or final electrical review.

Because the line uses Pentane in the foaming system, integration must also account for the gas detectors, ventilation fan, gas suction unit, and control panel.

The product information documents three panel profile options: Roof 4-rib, Cold Room, and Boltless hidden-fix panels. The system combines roll forming with a four-component high-pressure PU system, metering pumps, flow meters, a mixing head, and an oscillating foaming portal. The 24m double belt conveyor includes heating and automatic temperature control for the conveyor section.

The published product parameters list foam density of 35–50 kg/m³, panel thickness of 35–150 mm, maximum panel length of 15,000 mm, and line speed of 0–8 m/min. Actual production conditions can vary with the selected profile, materials, field conditions, and manpower; the product information itself notes that technical data may be changeable in field conditions.

The line includes equipment, accessories, and some buyer-scope items.

For procurement, ask for a project-specific spare-parts list covering the roll-forming section, PU metering and feeding equipment, conveyor, cutting system, sensors, and electrical controls. Also request the operating and maintenance documentation for the delivered configuration. Any recommended inspection intervals, lubrication points, consumables, and replacement parts should be confirmed against that project documentation rather than assumed from this general product description.

The published configuration includes a pentane safety control and monitoring system with six gas sensors, a control panel, ventilation, and a gas suction unit at the foaming zone. It also lists a pentane cylinder and feeding system. Gas-suction ducting to the outside is identified as buyer scope.

These listed components describe the equipment scope; they do not establish that a site is compliant with local fire, electrical, chemical, or occupational-safety requirements. Before operation, the buyer should obtain the applicable site-specific safety review, installation instructions, and operating limits for the delivered line.
