Crucibles Overview

Isopressed

Capital Refractories is able to supply a full range of isostatically pressed crucibles from 2 kg capacity to 75 kg, in different grades and qualities. We use a state-of-the-art semi-automated cold isostatic press. Cold isostatic pressing applies pressure to the workpiece in all directions producing products of uniform density. 

The advantages of Isostatically Pressed Crucibles are:

• Wide range of qualities
• Wide range of crucibles sizes
• Smooth internal surface giving a reduction of inclusions
• Consistent material properties throughout crucible
• Defect-free - no casting bubbles etc
• Uniform density throughout the product improving its resistance to thermal stress

Vibrocast

Crucibles are produced by vibration casting (vibrocast) when the required size or shape is uneconomical or impractical by the isopressing production method.

Capital Refractories can offer a range of vibration cast crucibles, including T-Pot Ladles:

Benefits
Complex shapes, e.g. internal pouring siphon

To complement our range of crucibles we also offer numerous ancillary products and materials used within the investment and related foundry industries.
