Short answer: Good aluminum HPDC mold design starts with parting, draft, wall uniformity, gating, overflows, cooling, and ejection—then steel selection matched to volume and thermal load. Fancy steel names do not fix a bad parting line.
MINDWELL designs and builds these tools in-house and runs aluminum (also Zn / Mg) programs on cells up to 1600T (LK).

Process
- Confirm alloy family (Al focus here) + cosmetic/structural class.
- Parting & draft review.
- Gate / runner / overflow / vent plan.
- Cooling layout vs expected cycle.
- Slides/lifters for undercuts.
- Ejector & machining stock plan.
- Release to manufacture + tryout loop.
Material
Common hot-work candidates discussed in industry (e.g. H13-class and equivalents) for aluminum dies.
MINDWELL statement: Mold steel grade per tooling specification / RFQ — industry steel names below are not a promise of warehouse stock.
Cast aluminum grades for the part: per RFQ.
Applications
Aluminum housings, brackets, covers, and heat-sink class geometries that justify HPDC tooling.
For magnesium lightweight programs, do not copy Al wall/gate habits blindly → Magnesium alloys and Mg vs Al.

Why MINDWELL
- Checklist engineers can skim in one screen.
- Separates “industry steel names” from “our stock promise.”
- Cross-links Mg without hijacking the Al article.
FAQ
Q: Is H13 mandatory?
A: It is a common industry choice for many Al dies; final grade depends on volume, soldering risk, and cost—set on RFQ.
Q: Do you design only aluminum dies?
A: No — Al / Zn / Mg. This article’s scope is aluminum design topics.
Q: Simulation?
A: Available when the RFQ requires it.
Q: Lead time?
A: Lead time quoted after DFM; we do not publish fixed week counts.
