Hemispherical Strainer Assembly with Perforated Dome Strainer Flange and Three Press-Fit Studs

A perforated dome strainer flange with holes drilled off-pitch in a secondary operation shifts the filtration area away from the dome center, creating uneven flow distribution and localised clogging under high throughput. Anhui Xinyue stamps this carbon steel perforated dome strainer flange with hemispherical dome profile, perforation pattern, and three press-fit stud positions all formed in a single progressive die sequence in Xuancheng, holding all dimensions to your specification tolerances in-die. Perforation pattern and stud position are verified per your drawing before release under IATF16949 and ISO 14001 certification at Xinyue's Anhui facility (roughly 20,000 m²). Applications cover automotive, pump/valve, oil & gas, and industrial strainer. Deep draw forms the dome geometry without secondary forming operations, serving aerospace, medical equipment, and military applications. Provide dome radius, perforation pitch, stud position, and material grade and your drawing for quoting. For a tooling and volume price estimate from our xuancheng team.
