Liners and Backup Crucibles

IMC has everything you will ever need in the way of single-use crucibles or ‘liners’, whether they are made of silica, alumina, or zircon.

The one-shot liners are used only once and replaced after every use. The complete system comprises a single-use one-shot liner that is placed in a reusable outer crucible, the backup crucible.

Advantages of using one-shot liners:

  • Clean melting technology
  • Inclusions are drastically reduced which will directly reduce rework and scrap costs
  • No risk of cross-contamination of alloys, as the liner is only used once

Determining the materials and the sizes of your liners is not the easiest task.
