Drawing, extrusion & tooling simulation
Cartridge cases, tubes and extruded sections are made in long chains of operations where one stage sets up the next. Simulating the full sequence shows wall-thickness evolution, forming loads and the stress in every punch and die — and where wear or cracking will end tool life.
Before the trial, not after it.
- Will the wall thickness and hardness profile meet the specification after the last draw?
- How many stages are needed, and how should reduction be split between them?
- Where are the die stress peaks, and how long will the tooling last?
- Will the part crack or wrinkle — and what changes prevent it?
Results you can act on.
- Wall thickness and strain per stage
- Forming loads and press requirements
- Die stress, deflection and wear
- Damage / fracture indicators
Where this matters most.
- Cartridge cases and shell casings (brass, steel)
- Drawn and flowformed tubes, rocket-motor cases
- Extruded and cold-headed fasteners
