Project background:
      The project client specializes in the production of polyurethane/rock wool color steel sandwich panels. With the rapid development of modern urban construction and the rise of industrial plants and other buildings, steel structure buildings have been widely used in various urban buildings, office buildings, various modern industrial plants and civil buildings, and the supporting wall enclosure materials And the demand for roofing materials is growing rapidly. Polyurethane composite panels (rock wool composite panels) are a new generation of decorative wall enclosure materials and roofing materials, and are the most popular new generation of steel structure building materials. It not only has the function of enclosure and heat preservation, but also has the function of decoration. It is the only new wall building material that can integrate enclosure, decoration and heat preservation. The traditional production line equipment is low in automation, labor costs are too large, product accuracy and equipment quality are also very low, and production efficiency is low. After customers have inspected six domestic and foreign companies, the polyurethane/rock wool color steel sandwich panel of Zhongji Machinery is fully automatic The production line won the bid. After it was put into production, the production line ran well and the output was stable, which brought huge economic benefits to customers.
Project advantages:
      The production line adopts domestic and foreign advanced roll forming technology, HCFC polyurethane foaming technology, composite transmission technology, CNC servo control technology, Frequency conversion vector control technology, hydraulic control technology. The entire line only needs five to seven operators to operate normally. The characteristics of this production line are: high degree of automation, fast production efficiency, simple operation, low production cost, and saving investment costs.
