Raw Materialalways insist on choosing a uniform powder of raw material to produce each of your sintered filters with great pore size, high tensile strength, and temperature stability. |
Isostatic PressingSintered filter cartridges are formed by isostatic pressing, where metal powders in a flexible mold are compacted evenly under high-pressure fluid for uniform density. |
Vacuum Sinteringstrictly controls the parameters of the high sintering process of sintered filters to give them good mechanical properties by applying heat and pressure |
CNCWe use high precision machining to manufacture the fitting of sintered filter cartridges, including internal and external threads, imperial and metric threads. |
