Ceramic extrusion for tubes and profiles
Extrusion forms shapes with cross-sections such as square, hexagonal, triangular, or circular. Items can be solid or multi-cored, with diameters from 3mm to 75mm and lengths up to 750mm. Tooling cost is normally low.
What is ceramic extrusion?
Extrusion is used to produce repeatable cross-sections in volume. Items can be solid or have multiple cores, with diameters that vary from 3mm to 75mm and lengths of up to 750mm.
Before firing, these shapes can be drilled or machined to produce further detail. Tooling cost is normally low, depending on how intricate the required shape is.
Extrusion capability
Cross-sections
Square, hexagonal, triangular, or circular, solid or multi-cored.
Diameters 3-75mm
A wide working range for tubes and profiles.
Lengths to 750mm
Long continuous sections in a single run.
Low tooling cost
Generally inexpensive tooling, depending on shape complexity.
Post-fire detailing
Pre-fired shapes can be drilled or machined to add detail.
