HERUN Ceramics helps engineers and purchasing teams source precision ceramic components for wear, insulation, heat and corrosion problems. Send a drawing, sample photo or working condition, and we will recommend material, tolerance and manufacturing route.
Most customers do not need a catalog part. They need a ceramic component that fits their machine, fixture or process.
Ground alumina and zirconia ceramic rods for guides, plungers, positioning pins, pump shafts and low-wear sliding parts.
Insulating tubes, thermocouple protection tubes, spacers, bushings and precision sleeves with custom inner and outer diameters.
Seal faces, ceramic washers, doctor rings, pump rings and wear-resistant round parts with lapped or polished surfaces.
Machined plates, substrates, fixtures, blocks with holes, wear plates and insulating supports for high-temperature equipment.
Custom caps, nozzles, tips, sleeves and special geometry parts for automation, printing, spraying and machinery systems.
Batch production after prototype approval, with material advice, inspection and export packaging for global buyers.
Material choice depends on load, temperature, electrical insulation, chemicals, friction and cost target. HERUN mainly supports custom alumina and zirconia components, with other advanced ceramics quoted when the application is suitable.
A drawing is best, but a clear photo and dimensions are often enough for the first discussion. For difficult parts, the working environment helps us avoid the wrong material or finish.
These pages give engineers a direct path from their problem to the right ceramic component.
Alumina and zirconia rods, shafts, sleeves, insulating tubes and protection tubes in custom dimensions.
High-temperature and electrical insulation parts for fixtures, welding, furnace, sensor and machinery use.
Precision rings, seal faces, washers and wear-resistant round components for pumps and rotating equipment.
