Insulated panel production line produces roofing or wall sandwich panels with EPS/ROCKWOOL/PU insulated. The panels perform great in HEAT-RESERVATION and THERMAL-INSULATION for your buildings.

The sandwich panel production line has been developed through the combination of roll forming and lamiating process. A sandwich panel has three layers (Top metal layer, Middle insulation layer and Bottom layer) and the core is the insulation layer. In order to satisfy people's needs of heat-reservation in freezing zone or thermal insulation in extremely hot area, insulated or sandwich panels are created. By filling insulation materials to roll formed roof or wall panels, people find it's a great try because it's much cozier staying in a house with insulated metal roof and wall sheets than without insulation. After then, there are increasing demands for sandwich panels in a variety of industries, like food industry, building industry, transportation industry, medical industry and so on.

EPS/Rockwool Sandwich Panels

The skin for EPS/rockwool sandwich panels are typically Pre-painted steel with thickness 0.3-0.6mm, width 1250mm maximum, and usually EPS or XPS board, and Rockwool or Glass mineral wool are applied as the the insulation materials. The steel and insulation materials are laminted to be sandwich panels with width around 1000mm and thickness 100-250mm.


EPS and Rockwool sandwich panels have different advantages, but both panels performs well in heat reservation and thermal insulation. Most importantly, both panels can be manufactured by the same sandwich panel production line.


A sandwich panel production line usually consists of decoiler, roll forming, edge shaping, lamination and fly-saw cutter. By using cross-moving double layer roll former, and ribs roller, it's possible to produce 4 roof panels with BOTH eps and rockwool, and 3 wall cladding sheets.

PU SANDWICH PANELS


INSULATION

FIRE-RETARDANT PU FOAM INSULATION, PERFORMING EXCELLENT FOR HEAT-RESERVATION AND THERMAL INSULATION, AS WELL AS FIRE RESISTANCE AND SOUND-MOISTURE PROOF.

DECORATION

3D-EMBOSSMENT PATTERNS DESIGN; GROOVE/RIBS ROLL FORMERD DESIGN; PRE-PRINTED PATTERNS DESIGN FOR DECORATION; FLAT SURFACE DESIGN; MULTIPULE DESIGNS COMBINED.

The integrated PU wall sandwich panel are composed of three layers, i.e. top layer (Pre-painted Gavalume steel), middle layer (Fire-retardant PU foame) and back layer ( moisture-proof aluminum foil). And as a result of such structure, the panel combines insulation project and facial decoration project of a building. Differet from EPS/Rockwool sandwich panels, the panel works only as wall cladding, instead of structural wall panels. In addition, the integrated wall panels are installed on both exterior and interior wall for insulation and decoration purposes. The panels would ensur at least 8 centi-degrees different between inside and outside of the building for as long as 30 years.

INSULATION & DECORATION INTEGRATED

PU WALL PANELS PRODUCTION LINE

The line for automatically and continuously manufacturing such panels integrates embossing, roll forming and lamination processes, and therefore typically is divided into embossing unit, roll forming unit, insulation unit, cutoff unit and control unit. The decorative metal wall panel production line makes exterior or external wall panels (the panels can be used as interior or internal wall sandwich panels as well) with different decoration patterns ( like brick, marble and wooden patterns etc.) embossed or printed on the metal face and PU or polyurethane insulated as thermal materials, out of prepainted or pre-printed steel coils with thickness 0.3-0.8mm and width 600mm automatically and continuously with running speed adjustable under the control of PLC system.

The line generally consists of two decoilers, an embossing machine for brick patterns, a roll forming machine (double layer roll forming machine and width adjustable roll forming machine are optional as per required profiles), a PU or polyurethane foaming machine, a cloth-belt composing or pressing machine with 24m length, a tracking fly-saw cutter, control system, transmission system and run-out tables.
