- Dual-skin roll forming stations synchronized for precise concealed joint fitting
- Automatic production with centralized PLC control across all line sections
The Z lock mineral wool sandwich panel line is an integrated production system engineered for the unique demands of rock wool core panel manufacturing. Unlike general-purpose lines, this system accounts for mineral wool's slower processing characteristics — higher density, greater adhesive absorption, and longer curing requirements — to deliver consistent A1 fire-rated panel output at commercially viable speeds. Every section from decoiling through final stacking is calibrated to work as one synchronized unit.
| Line Section | Equipment Installed | Role in Mineral Wool Processing |
|---|---|---|
| Material Infeed | Dual 5-ton hydraulic decoilers with pneumatic tension loop control | Feeds 0.5–0.8 mm steel at controlled tension to prevent strip wandering during Z lock forming |
| Top Skin Forming | 14-station upper roll bank, GCR15 chromed rollers | Shapes panel face profile and Z lock male rib; chromed surface resists mineral fiber abrasion |
| Bottom Skin Forming | 14-station lower roll bank, GCR15 chromed rollers | Shapes panel base profile and Z lock female channel; stiffening ribs added for heavier wool panels |
| Core Preparation | Rock wool batt loading station with lamella orientation conveyor | Positions fibers vertically for maximum compressive strength; pre-compresses batt to 90% target thickness |
| Glue Application | Dual-pump independent metering station, 200L tank capacity per circuit | Delivers 20–30% more adhesive than EPS lines to account for mineral wool's porous absorption |
| Panel Assembly | 9-meter heated double-belt lamination press with three temperature zones | Compensates for mineral wool's heat-sink effect during PU adhesive curing; uniform pressure prevents delamination |
| Edge Finishing | Dual-side |
