Castings
MetalTek offers more metal casting process diversity. Your ability to source centrifugal, sand, investment, HPLT, or continuous cast products from a single company is not available anywhere else in the world.
Which metal casting process should you select?
Centrifugal casting – When to use it:
- Symmetrical parts that can rotate on an axis.
- Static casting material properties are inadequate.
- Centerline shrink is an issue.
- Limited I.D. features.
- Large parts, up to 30,000 lbs./13,600 kg or more.
- Net shape: When finishing is expensive and tooling justifiable.
Sand casting – When to use it:
- Shaped or non-symmetrical parts.
- Large parts up to 15,000 lbs./6,800 kg or more.
- Internal structures.
- More liberal tolerances.
Investment casting – When to use it:
- Shaped or non-symmetrical parts.
- Smaller parts up to 300lbs./140 kg ship weight, with fine details.
- Parts have internal structures.
- Tight tolerances and thin walls.
HPLT casting – When to use it:
- Shaped or non-symmetrical parts.
- Large parts – Up to 14,000 lbs.
- Internal structures.
- More liberal tolerances.
- Very strict weld repair or “no weld” limits
Continuous casting – When to use it:
- Solid bars or tubes for further machining.
- Cast in shape rather than machining.
- Small usage – buy by the inch.
