Operating Manual

The roll forming and polyurethane foaming factory carry a lot of possibilities in the present world. Due to earth-quack resistant ability, heat insulating property , faster to construct, the polyurethane panels are the major substitute of bricks and cemented infrastructures. Polyurethane is formed by the exothermic reaction of polyol and iso - cyanate. The book presents the detail of production processes of metal sheets like CGI S-span sheet, normal sheet and Polyurethane Panel. The productivity analysis of Polyurethane panel, lab report of those panels which include density findings are the major parts of the research activities carried out in Sandwich Home Solution Factory at Bharatpur, Chitwan, Nepal. The book targets entrepreneurs, engineers and scientists and aim to provide the technical knowledge of various machines involved in the production.
