Large camera casing: die casting, extrusion and CNC machining

The customer arrived with a completed design and a specific ask: not from-scratch development, but engineering support to make that design production-ready and to reduce what it would cost to manufacture.

Engineering support was requested at the design-to-production stage, with cost reduction treated as a stated objective rather than an afterthought.

The redesign covered five areas together, because in a part that runs through three processes and two finishes the failure modes interact.

• Flow and thermal layout — the feeding system, the overflow and venting arrangement, and the cooling circuit layout were redesigned.
• Simulation before steel was cut — mould filling and solidification simulation was run on the new layout, so the defects were resolved in the model rather than in the tool.
• Tooling specification — the mould steel grade and the heat treatment process were changed.
• Part geometry — wall thickness, ribs, fillets and draft angles were adjusted.
• Finishing route — the masking strategy and the process sequence for anodizing and Alodine were optimized.

The die casting tooling and engineering / DFM review pages describe how these decisions are normally handled on a new project.
