Aluminium Rectangular Housing with Die Cast Housing Arm and Internal Ribbed Cavity

Internal rib junctions in die cast aluminium housings are prone to micro-porosity when die fill velocity and cooling parameters aren't controlled; porosity at rib intersections reduces structural strength and can cause leak paths in fluid-carrying assemblies. Ningbo Yujun controls this through IATF 16949-certified die casting with validated injection parameters, producing this aluminium housing arm with internal ribbed cavity and flat mating flange surfaces to your drawing's wall and rib dimensions. Flange face flatness and mating surface Ra are machined and verified after casting at the Ningbo, Zhejiang facility. Passivation, anodizing, and sandblasting are available in-house for corrosion protection and cosmetic finishing. In-house secondary processes include black oxide coating, chemical plating, and electrolysis. Output serves automotive, aerospace, and medical equipment buyers. IATF 16949 traceability covers material records and process documentation from die to finished part. Rib geometry, flange dimensions, and required surface finish. Yujun will confirm the casting parameters and provide a production quotation with lead time.
