Edge Sealing Rock Wool Color Steel Sandwich Panel Production Line

The edge sealing rock wool color steel sandwich panel production line integrates a PLC central control system to achieve full process linkage of foaming, edge sealing, and compression molding. It supports one click adjustment of thickness and speed, and supports switching between PU/PIR/rock wool multi-core materials.

The continuous edge sealing rock wool color steel sandwich panel production line adopts a fully modular design concept, and each functional unit can be combined in a modular manner. Core component manufacturing is completed through CNC machining centers, with a component exchange rate of over 95%, reducing equipment maintenance time by 60%. The entire production line is equipped with a centralized control system, which integrates the control points of 12 processes including uncoiling, molding, gluing, and compounding on the central console. Through an industrial bus, millisecond level response is achieved, and the accuracy of fault self diagnosis reaches 98.7%.

The continuous edge banding color steel rock wool sandwich panel production line adopts double track laminating technology. The upper and lower steel tracks can apply adjustable pressure of 0.5-3MPa, combined with a 60-100 ℃ gradient heating system (hot oil/electric heating optional). In the sandwich structure forming process of "steel plate adhesive rock wool adhesive steel plate", the polyurethane edge sealing process has achieved revolutionary innovation: the high-pressure foaming machine injects two-component polyurethane raw materials (isocyanate+polyol) into the side mold at a pressure of 2.5MPa, and after foaming and expansion, forms a continuous sealing layer with a closed cell rate of ≥ 92%, which improves the waterproof performance by 300% compared to traditional metal edge sealing strip schemes.

The automatic edge sealing rock wool color steel sandwich panel production line generally adopts high-power and low-energy consumption design, equipped with a fully enclosed internal insulation system. Actual test data shows that when the ambient temperature is ≥ 5 ℃, it only takes 52 minutes for the equipment to heat up to the process temperature, reducing energy consumption by 60% compared to traditional models. The waste heat recovery device can convert the thermal energy emitted by the laminating machine into electrical energy, meeting 15% of the power demand of the production line. The non hydraulic servo lifting mechanism achieves a thickness adjustment accuracy of ± 0.1mm for the sheet metal, while completely solving the problem of hydraulic oil leakage and pollution.
