1. Manufacturing Process

Manufacturing an Alumina Tube with 99.5% purity and a 30 mm outer diameter involves the precise blending of fine aluminium oxide powders to ensure a uniformly dense material. These powders undergo a controlled forming stage, typically using extrusion or casting techniques, to shape the tube into its desired dimensions. Once the form is set, the piece is dried to remove residual moisture and then sintered at high temperatures, transforming the green body into a resilient ceramic tube.

Ensuring dimensional accuracy is essential, so specialised tooling and temperature controls are employed throughout production. Every stage, from powder mixing to final sintering, is meticulously monitored to maintain tight tolerances and deliver consistent mechanical properties. This careful attention to detail allows the finished tube to exhibit exceptional hardness, thermal stability, and corrosion resistance.
