Die Casting Sample Lead Time -Realistic Phase-by-Phase Guide

The most common timeline disappointment: an engineer expects samples in 3 weeks because the quotation came back in 2 days. Die casting samples take 5-14 weeks depending on tooling type and complexity. Here is every phase, with realistic durations.

---

Phase 1: RFQ and Quotation -2- days

Submit drawing →KastMfg returns quotation + DFM report.

What slows it: Incomplete drawings (missing tolerances, no material spec), very complex multi-part programs, DFM issues requiring clarifying questions before quoting.

What helps: STEP file + 2D PDF with all tolerances, annual volume estimate, testing requirements stated upfront.

---

Phase 2: PO and Tooling Start -3- days

Approve quotation + issue PO + pay tooling deposit. KastMfg releases tooling to design.

Note: Wire transfers internationally take 2- business days. Tooling does not start until deposit clears.

Phase 3: Tooling Fabrication -the longest phase

Tool Type	Steel	Duration from Design Approval
Prototype, simple	P20	2- weeks
Prototype, 1 slide	P20	3- weeks
Production, simple	H13	4- weeks
Production, medium	H13	5- weeks
Production, complex	H13	7- weeks
4-cavity production	H13	7-10 weeks

Tooling progress reports at 50% and 90% completion are available for programs with agreed milestone reporting.

---

Phase 4: Trial and First Article -~1 week

• Trial run and parameter optimization: 1 day
• CMM first article inspection: 2- days
• Report preparation: 1- days
• Total: 4- days

If the trial reveals a tooling modification (gate, overflow, ejector pin): add 3-10 days depending on scope.

Phase 5: Sample Shipping

Method	USA	Europe	Notes
DHL/FedEx Express	4- days	4- days	Standard for prototypes
Economy air	7-10 days	6- days	Cost saving on larger shipments
Ocean freight	20-30 days	28-35 days	Only for large first-article quantities

Always use express air for prototype samples -$150-400 cost is trivial relative to development program time.

Total Lead Time (PO to Parts in Hand)

Scenario	Total
P20 prototype, simple, air freight	5- weeks
P20 prototype, medium, air freight	7- weeks
H13 production, simple, air freight	8-10 weeks
H13 production, medium, air freight	10-12 weeks
H13 production, complex, air freight	13-15 weeks

How to Expedite

Prototype tooling: P20 saves 2- weeks vs H13 -use for design validation before production tooling commitment.

Express tooling: KastMfg offers expedited fabrication (simple single-cavity: 2- weeks for P20, 4 weeks for H13) at premium rate. Available on confirmed programs.

Parallel processing: Don't wait for one phase to complete before starting the next. Begin production order paperwork during first article approval. Review the tooling design in parallel with commercial confirmation.

Planning for Production After Samples

First production delivery timeline from first-article approval:

• Production order + scheduling: 1- weeks
• Production run: 3- weeks
• Ocean freight: 20-25 days
• Customs + local delivery: 5-10 days

Total replenishment cycle: 10-14 weeks. Plan safety stock accordingly -8-10 weeks of consumption minimum.
