Extrusion.
Engineering calculations for the people
who know what goes into an extrusion.
THREE WORKING AREAS
One process.
Connected perspectives.
Plan the production. Explore the engineering.
Understand the economics.
One consistent Python toolkit.
02
Engineering
Explore source-traced material models and analytical mechanical and thermal tools, with explicit model boundaries.
- AA6060 / AA6063 rheology
- Axisymmetric pressure baseline
- Bounded thermal estimates
03
Economics
Connect production results to costs and margins using assumptions you supply and can inspect.
- Material & scrap economics
- Production & tooling costs
- Sales margins
ENGINEERING PHILOSOPHY
Real constraints.
Transparent calculations.
An extrusion is more than an extrusion ratio. The useful answer also depends on the press, the billet, the cuts and the time between them.
Read the model boundaries01 /
Deterministic by design
The same inputs produce the same results. Calculations follow explicit rules and caller-supplied assumptions.
02 /
Traceable from input to result
Inspect units, applied defaults, process choices and warnings. Know what each result represents.
03 /
Clear about the limits
Pressure is an axisymmetric screening baseline. Thermal tools are bounded estimates. Industrial judgement remains essential.

Updating an existing project? v0.20.0 adds explicit production-family selection when changing cuts. Automatic mode retains the 0.19.0 behavior. Review trim topology & legacy migration before reusing older inputs.
