What Drives Die Casting Part Cost

Tooling is usually quoted separately from the piece price. The tool cost reflects cavity count, slides, inserts, cooling layout and the expected production volume.

Amortization is a commercial decision. Some buyers pay tooling upfront, while others spread it across the first orders. Either way, the agreed volume should match the cavity and tool design.

• Tool cost reflects cavities and features
• Slides and inserts add cost
• Agree who owns and pays for the tool
• Match tool design to annual volume

The alloy price is quoted per kilogram, but the effective cost is driven by the shot weight, including runners, overflows and scrap that can be recovered.

Part weight reduction is one of the most direct ways to lower piece cost, which is why wall thickness, rib design and unnecessary mass are reviewed during DFM.

• Shot weight matters more than part weight
• Runner and overflow metal is recovered
• Alloy grade changes the price
• Wall and rib design affect weight

Cycle time sets how many parts a machine can produce per hour. It depends on part size, wall thickness, cooling design and the alloy being cast.

Yield and scrap are equally important. A slightly higher piece price with a stable process can be cheaper than a low price with repeated rejects and rework.

• Machine tonnage and cycle time drive cost
• Cooling design affects cycle time
• Yield and scrap change the real cost
• A stable process is worth a premium

Secondary operations can exceed the casting cost on precision parts. Bores, threads, sealing faces, flatness and surface finish all add operations and inspection.

Packaging, freight, duties and documentation also belong in the landed cost calculation, especially for export programs with rust prevention and labeling requirements.

• Machining often dominates total cost
• Finishing adds preparation and masking
• Include packaging and freight
• Compare landed cost, not piece price alone
