Almex Billet Tooling Performance
Casting your billets with the Almex OPTIMA™ mold technology puts you at the following advantages:
- Reduced subsurface segregation
- Very consistent extrusion and forged product properties
- Consistent bright dip anodizing response
- Easily reproducible casting response
- Uniform billet sub-surface properties throughout
- Improved casting pit recovery
- Improved casting pit productivity
- Reduced first step homogenizing cycle
- No contribution to ultrasonic “pick-up” as a result of variation in cell size, porosity, and precipitate size post homogenization
- Shorter “sonic-free” butt ends
- Reduced maintenance needs for tooling control
- Fastest payback period
- Inherently safe
