- Design and engineering: Based on the customer's requirements and specifications, the filter element is designed and engineered using advanced CAD software and simulation tools. - Material selection and preparation: Depending on the application and environmental conditions, the filter element may be made of various materials, such as stainless steel, bronze, nickel, titanium, or polyethylene. The materials are then prepared and processed into the desired shape and size. - Sintering and bonding: The materials are compressed and sintered at high temperatures and pressures to form a porous and permeable structure that allows the fluid or gas to flow through while retaining the contaminants and particles. The filter element may also be bonded or welded to other components, such as end caps, flanges, or housings. - Testing and quality control: The filter element is tested and inspected for various parameters, such as filtration efficiency, flow rate, pressure drop, and chemical resistance. It is also subjected to various quality control measures, such as leak testing, dimensional analysis, and surface finish inspection.
