A production line for PU-Rock Wool Panels (or similar sandwich / composite insulation panels) manufactures insulated panels made by sandwiching a rock wool (mineral wool) core between facings (usually steel sheets, aluminum foil, or other facing materials) possibly sealed on the edges with PU (polyurethane) foam or adhesives, producing panels with fire resistance, thermal insulation, structural strength, etc.
These are used for walls, roofs, cold storage, clean rooms, and other building/infrastructure applications.
Section | Purpose / Function |
Uncoller / Decoller | Takes the roll(s) of facing material (e.g. pre-painted steel coil) and unwinds them. |
Sheet leveling / flattening | Removes tension / deformation in the steel/metal sheet before forming. |
Feeding / alignment / trimming / slitting devices | To cut the edges,slit sheets to width,trim off edges as needed. |
Roll forming / profile forming (if facings have profiles or ribs) | Forms corrugations,ribs,or other profiles in the metal facings if required. |
Pre-heating / pre-treatment | Warms up sheet facings so adhesive or bonding works better;sometimes also to dry / prep. |
Adhesive / Glue spraying system | To coat facing sheets (top and/or bottom) with adhesive or glue to bond with rock wool core. |
Rock Wool System / Feeding | Supplies/places the rock wool core. Could be pre-manufactured rock wool mats/slabs,or a process that creates the core. Needs handling,cutting/slitting to correct size. |
Edge sealing / PU Foaming (depending on design) | For PU (or polymer) edge seal or side sealing to protect edges,improve bonding,seal joints. |
Double-belt or multi-belt pressing / laminating / curing system | To press the sandwich (facings + core) together,apply heat / pressure to cure adhesive / bond,ensure uniform density. |
1.Feed facing material: Steel coils are decoiled, leveled, trimmed/slit to width. If profiled facings are needed (ribbed, corrugated), roll forming occurs here.
2.Surface treatment / adhesive application: The facing sheets (top and bottom) get adhesive sprayed or coated to bond to the core.
3.Core placement / Rock Wool: Rock wool slabs or mats are positioned between the facing sheets. The rock wool might be pre-cut/slitted or shaped.
4.Edge sealing / PU foaming (if applicable): Side edges may be sealed with PU foam to prevent ingress of moisture, protect from damage, and to seal joints.
5.Lamination / Pressing / Curing: The sandwich is passed through double belts or a pressing system, often with heating, that press and cure adhesive and ensure good bonding.
6.Cutting to length: Once the panel is structurally stable, it's cut to required lengths via saws or band saws.
7.Cooling & Stabilization: The panel may require cooling and settling to avoid warping or distortion.
8. Stacking & Packaging: Finally panels are stacked, possibly wrapped or protected, then stored or loaded for shipping.
