Production line and factory setup overview
Produces continuous metal-faced PU/PIR insulated sandwich panels by coil handling, surface preparation, metered reactive chemical mixing, continuous laydown and double-belt curing, cut-to-length, profiling, protective-film application, packing and panel-performance testing.
Recommended lowest-entry line configuration This is a strategic reactive-chemical panel plant. Complete bankable feasibility on coil supply, approved PU/PIR chemistry, fire classification, ventilation, emergency response, utilities, maintenance and contract off-take before EPC selection.
Production process and implementation sequence
- Coil receipt and decoiling
- Surface cleaning/profiling
- Polyol/isocyanate dosing and mixing
- Continuous laydown between metal faces
- Double-belt cure
- Cut-to-length and edge profiling
- Protective film/packing
- Bond, density, thermal and fire-performance release
Products, capacity and market fit
- Approve an installed sample and buyer acceptance criteria.
- Launch with a defined product family and documented tool settings.
- Keep material and quality records for every batch.
- Continuous PU/PIR sandwich panels - Steel thickness/coating, core density, panel thickness, bond strength, thermal conductivity, fire classification, profile, cut tolerance and joint detail - Cold rooms, warehouses, industrial buildings, roofing/wall contractors and prefab projects
