HERUN manufactures custom ceramic parts from drawings, samples and working conditions, including alumina and zirconia rods, tubes, rings, sleeves, washers, spacers and OEM components. 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 custom ceramic parts that fit their machine, fixture or process, with the right material, tolerance and surface finish.
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.
Buyers use different words for the same need: custom ceramic parts, customized ceramic parts, bespoke ceramic parts or made-to-drawing ceramic components. HERUN treats these as drawing-based OEM ceramic parts made around your dimensions, working condition and quantity.
Typical requests include alumina rods, zirconia sleeves, ceramic tube insulators, precision rings, washers, spacers and special ceramic components that cannot be purchased as standard catalog items.
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.
