Application
In today’s competitive foundry industry, metal quality is the decisive factor between premium castings and costly rejects. Metal filtration, as a critical technology in the casting process, plays an indispensable role in ensuring product quality by effectively removing non-metallic inclusions, oxides, and other harmful impurities from molten metal through physical interception or chemical adsorption.
This metal filtration technology significantly improves the internal quality and mechanical properties of castings, making it widely applicable across various metals, including aluminum alloys, magnesium alloys, cast iron, steel, and superalloys. Its importance is particularly evident in the production of high-precision castings, thin-walled components, and high-performance alloy castings.
Beyond impurity removal, filter materials delivers multiple benefits: it reduces casting defects such as porosity and slag inclusions, enhances molten metal fluidity, and optimizes microstructure. These improvements collectively boost product reliability and service life, making filtration a vital process in modern foundry operations.
