The 8–12 Week Tooling Timeline Myth: What Really Affects Injection Mold Tooling Lead Times? [Podcast]

Tooling delays do not usually start when steel is being cut.

By that point, the design may already have been released, the tooling order placed, the deposit paid, the launch timeline shared internally, and the first sample date built into the project plan. But if the design was not fully ready, the DFM review was incomplete, the tool complexity was underestimated, or the wrong assumptions were made about steel, cavities, surface finish, or trial runs, the schedule may already be unrealistic.

That is why tooling lead time needs to be understood before the toolmaker starts machining.

In episode 331 of China Manufacturing Decoded, Adrian and Paul Adams, Head of New Product Development at Agilian Technology, discuss the common “8 to 12 week tooling” figure that many hardware founders hear before cutting steel. They explain where that number comes from, when it may be realistic, and why it can quickly become misleading for real consumer electronics, IoT, and hardware products.
