Machines： This polyurethane color steel sandwich panel discontinuous production line is mainly composed of uncoiling system, cold bending forming system, PU high pressure foaming system, 2+2 lamination system, heating system, stacking system, packing system and other equipments. Project conditions： Output：200000-300000㎡ Whole line length：about 90 m Labors：about 6-8 Laminating machine effective length：12m Heating method ：electricity Project background： The client of this project specializes in the production of polyurethane color steel sandwich cold storage panels. Polyurethane cold storage board is an ideal material for multifunctional new buildings. It has various superior properties such as heat preservation and fire prevention, and can be used for building heat preservation, as well as various cold storages, refrigerated trucks, etc. Due to its good thermal insulation effect, high strength, beautiful appearance, convenient construction and short construction period, it has become an ideal new thermal insulation building material in today's building materials, and is widely used. The traditional production line equipment has low degree of automation, high labor cost, very low product accuracy and equipment quality, and low production efficiency. After many inspections, the customer decided to invest in the dis-continuous production line of polyurethane color steel sandwich panels of Zhongji Machinery. After being put into production, this production line runs well and the output is stable, which brings huge economic benefits to customers. Project advantage： The production line adopts domestic and foreign advanced polyurethane foaming technology, composite transmission technology, numerical control servo control technology, frequency conversion vector control technology and hydraulic control technology. The entire line requires only six to eight operators to operate normally. The characteristics of the production line are: high degree of automation, easy operation, low production cost and saving investment cost.
