Nov . 2023Due to its excellent thermal insulation performance, extruded panels are widely used in key industries. Although the production process of XPS type foam board is not complicated, we must pay close attention to all links in the process to ensure that the extruded board produced meets national and industry standards.
Typically, the following steps include the extruded polystyrene-type foam board manufacturing process:
1. Step 1
This is mainly a plasticizing stage. We should use an automatic feeder to feed polystyrene resin, combustion booster, nucleating agent and other materials into the plastic extruder of the first stage.
2. Step 2
The secondary foaming, mixing and cooling processes occupy most of the second stage. Before injecting the environmentally friendly CO₂ foaming agent, the raw materials and other auxiliary materials are fully plasticized in the extruder.
In the second stage of the extruder, the foaming agent will be thoroughly mixed with some other raw materials, cooled, and then extruded through the mold.
3. Step 3
After extrusion, the pressure is quickly released, and the foaming agent is wrapped in plastic, rapidly expanding to produce closed cells, and polystyrene plastic will form a foam board together with honeycomb cells under the various actions of the cells.
4. Step 4
The forming plate is then molded using a forming tractor to obtain the required thickness and width, after which it can be cut into shape. This stage mainly adjusts the thickness and width of the cardboard.
In the production process of extruded board, in addition to the main engine, various auxiliary equipment is also used, such as extruded board surface wool drawing machine, recycling granulator, edge forming machine, grooving machine, automatic packaging machine, etc.
Lying in Nanjing Tangshan Industrial Area, Feininger (Nanjing) Energy Saving Technology Co., Ltd (shortened as Feininger) is established in the year 2001 and covers an area of 70 acres. Feininger is the first professional manufacturer of XPS Extrusion Line and XPS Foam Board here in China. At the same time we are the unique enterprise specializing in XPS Foam as well as developing, manufacturing and selling of XPS equipment.
As demonstration enterprise appointed by World Environment-protection Organization, National High-tech Enterprise, Jiangsu Provincial Enterprise in Building Efficiency, Feininger bears Innovation through her developing. The professional R& D center of Feininger has close co-operations with some academies and research institutions.
In the year of 2002, Feininger firstly design and manufacture high quality XPS Foam Board Production Line in China. Since then we have contributed to research of XPS technology, continuously improved the product, which enables us to be leader in XPS foaming industry home and abroad.
