Equipment Advantages
Hebei Wuzhou Zhengyuan New Material Co., Ltd. took the lead in adopting Austrian HIRSCH pre-expanding machine in the north to control EPS foaming accuracy from the source. The pre-expansion machine's automatic control mode can carry out unmanned operation, automatic sampling and automatic weighing during the foaming process. , Automatic recording, automatic error correction adjustment, from the precise control of the pre-fire density, the error is less than 1%. According to the HIRSCH foaming process, various high-density EPS foams can be achieved, with a maximum record of 320 grams, laying the solid foundation for various high-density applications.
Wuzhou Zhengyuan has been committed to the production of high-quality polystyrene boards. The company adopts a fully imported Austrian HIRSCH vertical slab forming machine. This is an innovative and fully automatic production process. The equipment is equipped with a single-sided or double-sided adjustable size die. Wall, independent heating & vacuum process on all four sides, steam pressure of 2.0bar, with WWS permeable plate, using low-pressure and large-flow molding process to make the EPS beads have uniform adhesion, good adhesion, low porosity, and product compressive strength High, low thermal conductivity; moisture content after molding is less than 3%, ensuring extremely high flexibility & high efficiency in production, and high-quality mass production. The machine can meet the production needs of different densities, such as large plates from 5kg-80kg. At the same time, according to different molding formulas, the production parameters are adjusted for the molding of various raw materials. Through accurate pre-setting, synchronously combined with the density adjustment function of the large board machine, the density level of the board can be minimized, which can be lower than the density level of 3%.
Every plate delivered by Wuzhou Zhengyuan is traceable. Pre-release, maturation, and slab forming records are all recorded throughout the process.
