Rapid tooling

Rapid Tooling: Lead Times, Limits and Real Cost

Rapid tooling marketing emphasizes the first date steel is cut. Production programs also care about the last date parts match the approved sample.

Speed claims

What rapid tooling usually optimizes

Rapid tooling searches focus on shortening the path to first plastic. That path often uses softer steel, simpler cooling, or a tool that will not carry the full production run.

Rapid tooling is often compared with one hardened steel tool that also runs production. That steel tool is often completed in 10 business days on qualified programs, depending on part size and complexity.

Rapid path versus straight to hardened steel

Hardened steel at NetProto

  • One tool build window with approved lead time figure.
  • Sampling on production steel.
  • Typical output 100,000+ parts from the same tool.

Typical rapid tooling path

  • First tool optimized for speed, not life.
  • Production steel follows after design freeze.
  • Two sampling cycles before stable production.

Ask before you buy speed

  • Will production parts come from the same cavity set as first shots?

  • Who pays for the second tool if the rapid tool cannot scale?

  • How is wear handled on filled or abrasive resins?

FAQ

Rapid tooling questions

Is rapid tooling a separate product from the production tool?

Rapid tooling is often compared with one hardened steel tool. That steel tool is often completed in 10 business days on qualified programs, and the same tool runs production.

When is rapid tooling compared with going straight to steel?

Rapid tooling is often compared with one hardened steel tool when the calendar is the concern. That steel tool is often completed in 10 business days on qualified programs, depending on part size and complexity, and the same tool runs production.

How many parts will rapid tooling make before it wears out?

Rapid tooling is often compared with one hardened steel tool on wear. A part count for that separate cavity is not published. A hardened steel tool from NetProto typically reaches over 100,000 parts. Treat that figure as typical.
