Metal extrusion shapes heated billets (400-500°C) through custom dies under 10,000 PSI hydraulic pressure. Complex profiles—including multi-chamber hollow sections—are formed via mandrel-assisted direct/indirect methods. Post-processing includes CNC straightening (±0.1mm/m) and aluminum alloy finishing.
Step 1: Upload CAD files for DFM analysis and tooling cost estimation.
Step 2: Sample approval with 3-axis CMM verification.
Step 3: Full production with real-time tooling lifecycle tracking via Tool Library.
