Key facts
Aluminum injection molds: 7075 and QC-10 prototype and bridge tools delivered in 10-15 days for 100 to 10,000+ shots - honest cost and lead-time comparison against steel tooling.
Aluminum tooling is the fastest honest way to real molded parts: real resin, real process, real dimensions – in half the time and a fraction of the cost of a production steel tool.
What Aluminum Tools Do Well
- Design validation with production resin – snap-fits, creep, finish, color
- Bridge production: sell or ship units while the steel tool is built
- Market tests and investor samples that behave like production parts
- Low-volume products under ~10,000 lifetime units
Aluminum vs Pre-Hardened Steel
Aluminum (7075, QC-10) machines roughly twice as fast, costs 30-50% less, and comfortably runs 100-2,000 shots of unfilled resin – more with gentle resins and good maintenance. Pre-hardened P20 costs more but handles glass-filled resins and 5,000-10,000+ shots. Both are built and inspected on the same equipment as our production tooling.
Honest Limitations
Aluminum is not for abrasive glass-filled resins in long runs, high-temperature engineering resins, or tools with complex sliding actions. When a project needs those, we say so and quote P20 or H13 instead – the same honest logic behind every Shiny Mold quote.
Where aluminum molds win – and where they do not
An aluminum tool cut from 7075 or 6061 ships in 10-15 days against 25-35 days for steel, and costs roughly 40-60 percent less. That makes it the right call for market-testing parts, bridge production while the production tool is cut, or annual volumes that never exceed a few thousand shots. Aluminum also machines faster, so design iterations cost days instead of weeks.
The limits are just as real. Aluminum wears quickly against glass-filled resins, tool life usually sits between 500 and 10,000 shots depending on resin abrasiveness and cycle conditions, and fine steel textures do not hold. For parts that must survive millions of cycles, start with our comparison of rapid tooling vs production tooling or read how P20 and H13 steels are matched to resin.
A concrete example from recent work: a consumer electronics tray, 1,500 annual units for market testing, quoted both ways. The aluminum option came in at about half the steel tool price and delivered parts in 12 days; the P20 steel option cost more but brought the piece price down 18 percent at volume through a faster cycle. The customer took aluminum for the launch year and the steel tool for year two – the two tools are not competing, they are stages. Where your program sits on that timeline is exactly what the quote compares; send volumes and we will price both, as shown in our rapid tooling service.
