A wide variety of products go into the crucible system for induction melting.

Crucibles can be isostatically pressed, for uniform density, or cast in capacities up to 3000kg.  Backing the crucible is a monolithic rammed lining, a slip plane and possibly an outer sleeve or a quick-change crucible-basket assembly; atomising or metering nozzles may be required for bottom pouring

The casting manufacturing system also allows for special shapes to be made, such as ladles, tundishes, launders, pouring spouts.

Crucibles up to 220mm in diameter are normally made by isostatic pressing. This method confers uniform density throughout the length of the crucible and through its’ walls. This eliminates problems from differential density variations which can occur in crucibles made by standard, end-to-end hydraulic pressing.

The method involves lowering the ceramic mix contained in a crucible mould into a chamber; liquid is pumped in until pressures of 10,000 to 15,000 psi (70 to 105 MPa) are reached. The released crucibles are fired at temperatures between 1500oCand 1750oC.

.A wide range of material types are available, differing in their ability to withstand particular chemical environments and balance physical erosion resistance with thermal shock resistance.
