How do I simulate an injection mold?

Open this page and use the live Learning Curve tool below — set your inputs and the simulation runs instantly in your browser using real numerics. No install, no account needed.

Yes. The simulation runs free in your browser. A one-time unlock or a Pro plan adds advanced parameters, saved presets, data import, and clean exports.

Can I use my own numbers?

Absolutely — every input is adjustable, and with data import you can drive an injection mold from your own measurements.

Cumulative units

Every time cumulative production doubles, the cost per unit falls by a fixed percentage — the learning curve. An 80% curve means the 200th unit costs 80% of the 100th. This steady, predictable decline, first seen in aircraft manufacturing, drives the falling prices of everything from solar panels to microchips, and underpins production planning and pricing.

Cost reduction77%

Governing equation

C_{n} = C_{1} n^{- b}, b = - lo g_{2} (0.80) = 0.322

Reading this result: An 80% curve means every doubling of output trims 20% off the unit cost — so by unit 100 you are paying about $23, a 77% drop from the first unit. Lower rates bend the curve down faster.
