HERUN manufactures alumina ceramic rods, Al2O3 rods, ceramic pins and shafts from drawings for insulation, wear resistance, high-temperature fixtures and OEM equipment. Custom diameter, length, chamfer, grinding and polishing are available.
Alumina rods are selected when metal rods conduct electricity, plastic rods cannot handle heat, or standard materials wear too quickly.
Alumina rods for electrical isolation, heating equipment, sensor support and high-voltage assemblies.
Ceramic pins and guides for automation, fixtures, positioning and sliding contact where hardness matters.
Al2O3 rods for furnaces, thermal equipment, welding fixtures and process support parts.
Ground rods and shafts for low-wear contact, pump components and drawing-based machine parts.
Custom length, diameter, chamfer and end face grinding based on the drawing or assembly requirement.
Prototype and repeat production for industrial buyers that need stable dimensions and export packaging.
Most alumina ceramic rods are made from 95% to 99% alumina depending on cost, insulation, temperature and surface requirements. Precision rods can be diamond ground after sintering.
They are used as insulating rods, guide pins, positioning pins, wear-resistant shafts, furnace supports and high-temperature fixture components.
Yes. HERUN manufactures custom alumina ceramic rods from drawings or sample photos, including custom diameter, length, chamfer, tolerance and surface finish.
Send diameter, length, material purity, tolerance, end treatment, surface finish, quantity and working conditions such as heat, wear or insulation.
