How Can Mould Makers Quote More Accurately Using Past Job Data?

Mould makers can quote more accurately by using the real, recorded costs of past jobs — actual design hours, machining time, trial loops, and material — as the basis for new quotes, instead of relying only on estimates and experience. Quoting from past job data means comparing a new enquiry against genuinely similar moulds already completed and pricing from what those jobs actually cost, which is almost always more reliable than the assumptions used in a first estimate.

This matters because in toolmaking the quoted price is fixed for a one-off job, so an inaccurate quote either loses the work or wins it at a loss — and the best correction for that is the shop’s own history of what similar jobs really took.

Why estimates alone fall short

When a new RFQ for a mould arrives, most tool rooms quote using a costing template plus the estimator’s judgement. The trouble is that these assumptions often trace back to earlier estimates rather than to what jobs actually cost once built. If a certain type of mould consistently takes more design revisions or trial loops than assumed, that pattern repeats in quote after quote — the shop systematically underprices that kind of work without realising it, because the real outcomes never feed back into the next estimate.

What “quoting from past data” looks like

To quote a new mould from history, a maker would look at:

Comparable completed jobs — moulds of similar type, size, and complexity already delivered.

Their real costs — the actual design hours, machining and EDM time, material, and number of trial-and-correction loops those jobs required.

Quote-versus-actual — how the original quote on those jobs compared to what they truly cost, revealing where estimates tend to be optimistic.

With this in front of them, the estimator prices the new job against reality: building in the design revisions that this type of mould always seems to need, the true machining hours, the realistic number of trials.

Why it is hard to do today

The obstacle is access. The real cost history of past jobs is scattered across design records, machine logs, material purchases, and closed job files. Pulling together the true cost of comparable jobs at the moment a new quote is due is effectively impossible by hand in the time available, so the shop falls back on estimates — and repeats past pricing mistakes.

How it is done effectively

To quote from history, a tool room needs its completed-job costs captured and accessible, so that similar past jobs and their real outcomes can be surfaced quickly when a new RFQ comes in. This is the kind of capability a CEO intelligence layer provides — connecting to the systems that hold design, machining, material, and costing data, and making each finished job’s true cost available to inform the next quote.

Quoting from real job data closes the loop that is normally broken in toolmaking: the reality of finished jobs feeds back into the pricing of new ones. Over time, this means winning the right work at the right price, walking away from jobs that would lose money, and steadily improving quoting accuracy with every job the shop completes.
