Tooling, sized to the volume that actually pays for it.

Injection molds, die-casting tooling, progressive stamping dies and production fixtures — designed and specified against your real volume, not oversold on a bigger tool than your order justifies.

Quick definition

Tooling is the fixed, reusable hardware — a mold, a stamping die, or a fixture — that a process needs to produce the same part over and over. Injection molds shape plastic parts, die-casting molds shape molten metal alloys, stamping dies punch and form sheet metal in one hit, and fixtures hold a part in place for machining, welding or assembly. Tooling cost is fixed regardless of volume, which is why it only pays for itself once you're ordering enough parts to spread that cost thin.

Sized to your volume, not the shop's default

Priced by the shop that wants to sell you steel, not by your actual volume.

Ask around for tooling and you'll often get quoted the safest, most expensive option — hardened steel, sized for volumes you may never hit — because it's the easiest quote to write, not the cheapest tool for your order. Send OperGo your real target volume and your engineer sizes the tool to it: aluminum or a lower-cavitation die when that's genuinely cheaper, steel and higher cavitation only once the math says it pays for itself.

Tooling sold by default
  • Steel tooling quoted by default, whether or not your volume justifies it
  • No breakeven conversation — just a tooling line item and a per-part price
  • Cavitation sized for a "just in case" volume, not your actual forecast
  • A new quote needed if you switch process partway through the decision
The OperGo way
  • Tooling sized to your real volume — aluminum bridge tooling, steel, or a progressive die, whichever pays off
  • A clear breakeven conversation before a cent is spent on steel
  • Cavitation matched to your actual forecast, not padded for a "maybe"
  • One engineer who can requote the same part across injection, die-casting or stamping if the volume math changes

What we run

The tooling behind every repeatable process.

Injection molds

Aluminum bridge tooling or hardened P20/H13 steel for production plastic parts — full depth on the Injection Molding page.

Die-casting tooling

Steel dies for aluminum, magnesium and zinc alloy die casting, casting complex metal parts without a machining program.

Progressive stamping dies

Multi-station dies that cut, form and pierce sheet metal in one hit — typically justified above 50,000 units.

Production fixtures

Jigs and fixtures that hold a part in place for machining, welding or assembly — the tooling that makes a repeatable process actually repeatable.

CNC machining likely wins

At 251 units of a moderate part, mold tooling is hard to fully amortize — CNC keeps you off the hook for tooling cost and lead time.

Picking a process

Tooling is the right call — once your volume earns it.

Tooled processes vs. CNC or 3D printing →

Tooling only pays for itself once you're ordering enough parts to spread its fixed cost thin. Below that volume, CNC or 3D printing usually wins on total cost, even at a higher price per part.

Die casting vs. injection molding →

Die casting shapes molten metal alloys into complex parts a machining program would take hours to cut. Injection molding does the same job in plastic — the choice comes down to what your part's material actually needs to do.

Molds & tooling, answered

What's the difference between a mold, a die and a fixture?

A mold shapes molten or semi-molten material — plastic in injection molding, metal alloy in die casting — inside a cavity. A stamping die cuts, punches and forms sheet metal between a punch and a die in one hit. A fixture doesn't shape anything — it holds a part in a fixed position so a separate process (machining, welding, inspection) can repeat accurately. All three are 'tooling': fixed, reusable hardware that makes the next hundred, or the next million, parts come out the same as the first.

How much volume do I need before tooling makes sense?

It depends on the process. Progressive stamping dies typically pay for themselves above roughly 50,000 units, because the die itself is expensive to cut. Injection and die-casting tooling can pay off at lower volumes — sometimes a few thousand units — because a simpler aluminum or lower-cavitation tool costs much less to build. Your engineer runs the actual math against your part and volume before recommending steel.

What's the difference between die casting and injection molding?

Die casting injects molten metal alloy — aluminum, magnesium or zinc — into a steel mold; injection molding does the same with molten plastic resin. Both use a similar tooling concept (a cavity, a cooling cycle, an ejection system), but die casting is for parts that need to be metal, for strength, conductivity or heat dissipation a plastic part can't match.

Can the same tool be used for both prototyping and production?

Usually not directly — a prototype tool (aluminum, lower cavitation) is built to validate the part cheaply and quickly, while a production tool (hardened steel, higher cavitation) is a separate, more expensive build sized for the full run. The part design validated on the prototype tool carries over; the tool itself typically doesn't.

What materials can be die-cast?

Aluminum alloys (AlSi10Mg, AlSi12, AlSi9Cu3 among others), magnesium (AM60B, AZ91D) and zinc/Zamak alloys (ZA-8, Zamak 3, Zamak 5) — picked by the strength, weight and cost your part needs.

What's a progressive die, and why does it need high volume?

A progressive die moves the sheet metal strip through several stations in one press stroke — cutting, piercing and forming the part in stages as it advances. Building a die with that many stations is expensive, which is why it's typically only worth cutting once your order is in the tens of thousands of units; below that, laser cutting and bending usually wins on total cost.

What if tooling isn't the right call for my volume?

Then your engineer says so before any steel is cut. If your volume doesn't justify a mold, a die-casting tool or a stamping die, they'll recommend CNC, sheet metal or 3D printing instead — and revisit tooling later if your volume grows into it.
