PROJECT REQUIREMENT
What had to be confirmed.
The customer supplied a controlled drawing for an aluminum housing with cast geometry and machined functional interfaces. The RFQ review needed to confirm application, alloy specification, expected quantity, revision, cosmetic surfaces, critical dimensions and required records before quotation.
The project template separates customer requirements from assumptions. Any missing alloy designation, numerical tolerance, surface-finish value, test condition or production quantity must be listed as an open item and confirmed before tooling or production release.
MANUFACTURING CHALLENGE
What required engineering attention.
The housing combines broad walls, ribs, bosses, openings and local section changes. These features can affect filling, solidification, gas or shrinkage porosity, distortion, ejection and the stability of downstream machining. Wall transitions, radii, draft, parting, gates, overflows and ejection conditions therefore require coordinated review.
Machined mounting faces and bores create an additional datum and allowance challenge. The engineer must identify the as-cast references, machining setup, critical interfaces and inspection access rather than applying one general tolerance to the entire component.
