About this product
We supply precision-engineered refractory components for the controlled flow and transfer of molten metals, covering superalloy casting through to ferrous and non-ferrous production. The range includes distribution (hot top) boxes, ceramic launders, tundishes, and pre-cast refractory shapes — designed for precise dimensional control, stable flow paths and high-temperature reliability. Choice of forming methods including slip casting, injection moulding, isostatic pressing and mechanical pressing allows us to match the right production route to your volume, complexity and tolerance needs. Optional flow control accessories — filters, dams, nozzles — can be supplied pre-fitted for full system integration.
What that means for you
Controlled molten metal flow
Labyrinth baffle and weir designs ensure accurate flow control and stable metal distribution during casting.
Material grades to suit process
Choice of alumina grades up to 96%, matched to alloy chemistry, temperature, erosion risk and thermal shock requirements.
High dimensional accuracy
Advanced forming, casting and machining processes deliver tight tolerances and excellent surface finishes for cleaner metal product.
Complex geometries & custom designs
Single piece or sectional designs manufactured to meet exact furnace layouts and process requirements, small scale to multi-metre assemblies.
Multiple forming processes available
Slip casting, injection moulding, isostatic pressing or mechanical pressing — allowing the ideal production route for volume, complexity and tolerance.
Optional flow control integration
Filters, dams, nozzles and engineered accessories can be supplied pre-fitted for full system integration.
Cleaner metal output, fewer re-work steps and scrap yields, longer component life and reliable, consistent performance — with parts engineered to fit your process, not the other way around.

Other ceramic components
Your questions answered
What metals and alloys are these components used for?
They support clean handling of superalloys, ferrous and non-ferrous metals — including steel, aluminium, copper, nickel-based alloys and cement/chemical process melts.
Can you supply integrated filtration?
Yes. Optional ceramic foam filters, dams, nozzles and engineered accessories can be supplied pre-fitted for full flow control integration.
How are these components manufactured?
Through slip casting, injection moulding, isostatic pressing or mechanical pressing — selected to match your tolerance, complexity and volume requirements.
Are sectional designs available for large launders?
Yes. Single-piece launders are available for shorter distances, with multi-section designs supplied for stable transfer of molten metals across longer distances.
What alumina grades do you offer?
Up to 96% alumina is standard, with higher-purity grades and reinforced refractory blends available for demanding alloy chemistries or extended durability requirements.
