What We Manufacture

Customized Ceramic Parts for Industrial Applications

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.

Rods, pins and shafts

Ground alumina and zirconia ceramic rods for guides, plungers, positioning pins, pump shafts and low-wear sliding parts.

Tubes and sleeves

Insulating tubes, thermocouple protection tubes, spacers, bushings and precision sleeves with custom inner and outer diameters.

Rings, seals and washers

Seal faces, ceramic washers, doctor rings, pump rings and wear-resistant round parts with lapped or polished surfaces.

Plates and blocks

Machined plates, substrates, fixtures, blocks with holes, wear plates and insulating supports for high-temperature equipment.

Nozzles and small precision parts

Custom caps, nozzles, tips, sleeves and special geometry parts for automation, printing, spraying and machinery systems.

OEM ceramic assemblies

Batch production after prototype approval, with material advice, inspection and export packaging for global buyers.

Product Selection

Find a Ceramic Component for Your Equipment

Explore rods, seals and custom components, or compare materials before specifying your part.

Alumina rods

Custom Al2O3 rods, pins and shafts for insulation, wear resistance, furnace fixtures and OEM equipment.

Ceramic seals

Ceramic seal rings, faces, sleeves and pump wear components made from drawings or measured samples.

Custom OEM components

Explore drawing-based parts for your equipment, including insulating supports, spacers and precision wear components.

Wear-resistant material selection

Compare hard ceramic materials and choose manufacturable alumina or zirconia wear parts for real equipment.

Custom, Customized and Bespoke Ceramic Parts

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.

What Makes a Custom Part Quoteable?

Clear dimensions, drawing, sketch or sample photos.
Material direction such as alumina, zirconia or unknown.
Critical tolerance, surface finish and contact surfaces.
Working temperature, load, insulation, wear or chemical exposure.
Prototype quantity and expected batch quantity.

Materials We Commonly Recommend

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.

Alumina Al2O3 for insulation, wear resistance, chemical stability and cost-effective production.
Zirconia ZrO2 for higher toughness, smooth sliding surfaces, seal parts and precision wear components.
Material selection support when the buyer only knows the working condition, not the ceramic grade.

Information Needed for a Fast Quote

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.

Drawing, 3D file, sketch or sample photo.
Material preference or working conditions.
Key dimensions, tolerance, surface finish and quantity.
Temperature, wear, corrosion, insulation or load requirements.

Electronics and Process Equipment

Ceramic Substrates and Semiconductor Equipment Components

Discuss custom alumina plates, insulating spacers, sleeves and fixture components for your equipment. Suitability depends on the part's function and operating environment.

Specify the substrate and its interfaces

For ceramic substrates and insulating plates, include length, width, thickness, hole positions, edge details and the surfaces that contact other components. Identify which dimensions and flatness requirements are essential to the assembly.

Tell us whether the request is for a bare ceramic part or requires metallization, conductive patterns or bonding. Those additional processes need a separate capability review before quotation.

Describe the equipment environment

For semiconductor equipment, identify whether the part is a fixture, electrical insulator, support or process-contact component. Include operating temperature, thermal cycling, vacuum exposure and cleaning chemicals where relevant.

Specify any particle, purity, surface cleanliness or packaging requirements. Semiconductor process compatibility and acceptance criteria must be agreed for the particular application; they are not implied by the material name alone.

Details That Help Us Quote the Right Part

Mark the features that matter to performance so the quote reflects your actual assembly requirements.

Specification checklist by component type
Component	Details to include	Application information
Rods and pins	Diameter, length, straightness, end shape and mating fit.	Sliding contact, positioning, insulation or support; describe the load.
Tubes and sleeves	Inner and outer diameter, length, wall thickness and concentricity where critical.	Mating shaft or housing, operating clearance and temperature.
Seal rings	Ring dimensions, sealing face, flatness and surface finish requirements.	Counterface material, fluid, pressure, speed and operating temperature.
Plates and substrates	Thickness, flatness, hole pattern, edge condition and contact surfaces.	Mounting method, electrical function, heat exposure and any coatings.

Achievable tolerances and inspection requirements are confirmed after reviewing the material, geometry and quantity. If a dimension is not critical, identify it separately from the functional fits.

From Inquiry to Production

Plan Your Custom Ceramic Order

Start with a technical review

Describe the part, material preference, dimensions, application and quantity. A sketch or sample photo can help when a finished drawing is not available. Include the current failure mode when replacing a worn or broken component.

Before ordering, confirm the drawing revision, material grade, critical dimensions, finish, inspection documents and delivery requirement with us.

Agree how the part will be accepted

For a new design, discuss a prototype or sample evaluation before committing to repeat quantities. Define the checks needed for fit and function in your equipment.

Request any material certificates, dimensional reports, traceability or special packaging at quotation stage so availability and cost can be confirmed. Lead time and minimum order quantity depend on the reviewed part.

Custom Ceramic Parts FAQ

Can I request a quote without a finished drawing?

Yes. Start with the part's purpose, approximate dimensions, quantity and a sketch or sample photo if available. Final production dimensions and acceptance requirements need to be agreed before manufacturing.

Can you quote ceramic substrates for semiconductor equipment?

We can review inquiries for custom alumina substrates, plates and insulating components. Include the equipment function, material grade, geometry and cleanliness requirements. Metallization, coatings and process compatibility require a separate review.

What are the minimum order quantity and lead time?

These depend on material, geometry, finishing, tooling and inspection needs. Share both your trial quantity and expected repeat demand so the quotation can address each stage.
