Rapid Production of Investment Casting Shells

Rapid Production of Investment Casting Shells, also called lost-wax casting or plain investment casting, is one of the oldest known metal-forming techniques.

The process is generally used for small castings, but has produced complete aircraft door frames, steel castings of up to 300 kg and aluminium castings of up to 30 kg.

It can produce complicated shapes that would be difficult or impossible with die casting, yet like that process, it requires little surface finishing and only minor machining.

Investment casting offers production of low batch custom made parts, particularly for small or highly complex components, and extremely good surface finish (CT4-CT6 class accuracy and Ra1.6-6.3 surface roughness) with very little machining. The drawbacks include the specialized equipment, costly refractories and binders, many operations to make a mold, and occasional minute defects.

Cyclone is the latest innovative technology to rapidly produce investment casting shells in hours rather than days.

Applications & Benefits

• Fast Production of Shells
• Increase Productivity
• High quality shells produce excellent casting in any type of metal
• Mould is 50% stronger minimizing the risk of cracked shells and reducing the number of layers resulting in less material consumption
• Environmentally friendly (no alcohol based slurries)
• High integrity parts such as medical implants can be created without worry of certification
