High purity and high quality raw materials are used to ensure that the materials have good chemical properties. The international advanced vacuum hot pressing sintering method is adopted to ensure the excellent physical properties of the products. The sintering process adopts bidirectional pressing method to ensure the consistency of the volume density of the products. Digital control of production equipment ensures the stability and consistency of product quality. The UNIQUE process formula optimIZES the component structure, ENHANCES the thermal impact resistance and flexural strength of the evaporation boat, improves the spread area and evaporation efficiency of liquid aluminum, enhances the corrosion resistance of the base material to liquid aluminum, and prolonging the service life.
