Draft · wall thickness · undercuts · gates & venting · should-cost
Feed MoldDFM a part and it runs the mold-maker's checks — draft by pull axis, wall thickness against the resin, undercuts that need slides or cores, gate placement and fill-length risk, vent locations — then prices the tool and the piece part together, cavity count and all.

The problem
A part goes to a tool shop, gets quoted, and only then does someone find the vertical wall with no draft or the boss that needs a lifter — after the tool's already being built.
Molders quote the tool on one number and the piece price on another — nobody puts them on the same curve to show the cost that actually matters: per part, at your real volume, tooling included.
Whether a single gate fills the part or short-shots the far wall usually gets discovered on the molding floor, not on the drawing.
What you get
Draft is measured face by face against the pull axis, area-weighted so a few sliver faces don't skew the number; undercuts are found by scanning for geometry no straight pull can release, each one flagged with its volume and location.
X, Y, and Z are each scored on undercut volume, draft rework, and mold footprint, so you pick the parting line before the tool's built, not after.
The flow path from the best gate location is measured against the resin's spiral-flow limit; when it's short, the gate count that would fix it comes with the finding — plus the last-to-fill spots that need a vent.
Clamp tonnage sets the cavity count, the mold prices off the same block-and-machining model as the rest of the suite, and the should-cost curve shows exactly where the tooling pays for itself.
How it works
Upload the STL or STEP model — no draft angle to set up first.
Draft by pull axis, wall thickness against the resin, undercuts flagged with volume and position.
The flow-length check names the gate count and the vent locations before anything's cut.
Cavity count, mold tooling cost, and piece price at your quantity — together, not two spreadsheets.
Pricing
Priced for a single designer and a production molder alike. Draft, undercut, and flow checks are unmetered — run as many parts as you like.
EUR prices exclude VAT, added at checkout where it applies. Early adopters keep their price as the suite grows.
Run it your way
Sign in and check a part from any browser. We run the compute, ship the updates, and keep your data yours — the shared model only ever learns from your own jobs to calibrate your rates.
Defense, medical device, and anyone under NDA can run the whole thing on their own hardware. Licenses and updates are signed files — it never phones home, so an air-gapped install stays air-gapped.
