Hebei Greens Building Material Technology Development Co., Ltd has introduced a new Stone Wool Sandwich Panel Production Line built around a rational structure, complete functionality and straightforward operation. The line runs a fully automated continuous process from coil to finished panel, and is aimed at manufacturers of rock wool insulated panels for cold storage, industrial buildings and prefabricated construction.
The design priority is consistency: every station is synchronised so that foaming, curing and cutting happen at matched speeds, which is where most sandwich panel lines lose quality and yield.
The line delivers a continuous workflow covering the whole panel build-up:
The metering pump system delivers accurate dosing with stepless speed adjustment, so glue consumption stays repeatable from the first panel to the ten-thousandth, and adhesive waste is kept under control.
| Parameter | Specification |
|---|---|
| Material type | Colour steel sheet, galvanised sheet, aluminium sheet |
| Material thickness | 0.3-0.8 mm |
| Material width | Up to 1250 mm |
| Panel length | 2,000-18,000 mm |
| Panel width | 500-1200 mm |
| Panel thickness | 30-250 mm (excluding corrugation height) |
| Production speed | 3-15 m/min, adjustable |
| Valid length of double belt conveyor | 12,000-42,000 mm |
| Working pressure at foam pouring | 150-200 bar |
| Total power | 660 kW / 300 kW |
| Overall dimensions | 130,000 × 15,000 × 6,000 mm (L × W × H) |
The 12,000-42,000 mm valid length of the double belt conveyor, combined with 150-200 bar pouring pressure, gives the foam core enough time and pressure to fill the cavity fully and cure flat. The result is a panel with uniform density, tight dimensional tolerance and no voiding along the edges — the defects that most often trigger rejection on site.
Speed is adjustable from 3 to 15 m/min, letting a producer run slower on thick 250-300 mm panels and faster on standard 50-100 mm boards without changing tooling.
Stone wool sandwich panels are specified where fire performance and thermal insulation must both hold: cold storage rooms, logistics and industrial halls, clean rooms, modular buildings and external cladding. Because the line accepts colour steel, galvanised, aluminium and stainless steel skins, one machine can serve several product families and market segments.
The Stone Wool Sandwich Panel Production Line is available for order with engineering, installation guidance and operator training included. Buyers are invited to share target panel dimensions, line speed and workshop layout for a tailored configuration and quotation.
