Custom alumina and zirconia ceramic components from HERUN Ceramics

Ceramic Component Manufacturers

Drawing-Based Ceramic Components, Not Catalog Guesswork

Most industrial ceramic components are designed around a machine, fixture, pump, sensor or production process. HERUN reviews the drawing and working condition before recommending material and production route.

Custom ceramic rods and shafts

Alumina and zirconia rods, plungers, guide pins, shafts and positioning components for wear, insulation and dimensional stability.

Ceramic tubes and sleeves

Insulating tubes, protection tubes, bushings, spacers and precision sleeves with custom inner diameter, outer diameter and length.

Ceramic rings and washers

Seal rings, wear rings, washers, spacers and round components for pumps, valves, rotating equipment and industrial assemblies.

Precision plates and blocks

Insulating plates, blocks, support parts, fixtures and substrates with machined holes, slots, grooves and working surfaces.

Small special-shaped components

Nozzles, caps, guides, seats, inserts and other custom ceramic components for automation, printing, sensors and machinery.

Prototype to repeat production

Support for sample review, prototype batches, inspection and repeat production after the component design is confirmed.

Industrial Applications We Understand

HERUN focuses on custom ceramic components for real equipment manufacturers and industrial buyers, not only simple stock shapes.

Pump, valve and mechanical seal components.
Electrical insulation parts for fixtures, sensors and high-voltage assemblies.
Wear-resistant ceramic components for sliding, guiding and abrasive contact.
High-temperature tubes, supports and furnace-related ceramic parts.
Precision ceramic parts for lab instruments, optics, electronics and automation.

Why OEM Buyers Choose Custom Ceramics

Hardness and wear resistance where metal or plastic parts fail quickly.
Electrical insulation at high temperature or in compact assemblies.
Chemical stability for pumps, valves, lab and process equipment.
Stable geometry after sintering, grinding and polishing.
Material support when the buyer knows the problem but not the ceramic grade.

Material Selection

Alumina and Zirconia Custom Ceramic Components

The correct material depends on load, temperature, wear, impact, insulation and chemical exposure. These are representative choices for early design discussion.

Material	Best fit	Typical component examples	Design notes
Alumina Al2O3	Insulation, wear resistance, heat and cost-effective production	Insulating tubes, washers, spacers, rods, rings, plates	Good first choice for many technical ceramic components.
Zirconia ZrO2	Toughness, polished sliding contact and precision wear parts	Sleeves, bushings, shafts, plungers, seal parts	Useful when chipping risk or sliding surface quality matters.
Other advanced ceramics	Special thermal, wear or chemical requirements	Application-specific rings, tubes, seats or inserts	Quoted when material and quantity fit the process.

Information Needed for a Fast Quote

A drawing is the fastest path, but a sample photo and measured dimensions can start the review. For technical ceramic components, the working condition is often as important as the shape.

Drawing, CAD file, sketch or sample photo.
Material preference, or the reason the current part fails.
Critical dimensions, tolerance, surface finish and working surfaces.
Temperature, voltage, wear, corrosion, load or sliding condition.
Prototype quantity and expected annual or batch quantity.

FAQ

Custom Ceramic Component FAQ

What information is needed to quote a custom ceramic component?

A drawing, sketch or sample photo is best. Please also include material preference, dimensions, tolerances, surface finish, working temperature, wear or insulation requirements and estimated quantity.

Can HERUN manufacture custom ceramic components from samples?

Yes. HERUN can review sample photos and measured dimensions for many rods, tubes, rings, sleeves, washers, spacers and special ceramic components before making a production drawing.

Which ceramic materials are commonly used for industrial components?

Alumina is commonly used for wear resistance, electrical insulation and cost-effective production. Zirconia is often selected for higher toughness, polished sliding surfaces and precision wear parts.

OEM Component Scope

Custom ceramic components organized by engineering need

HERUN focuses on made-to-drawing alumina and zirconia parts for buyers who need a specific fit, working surface or service condition. The fastest route to the right page is to start with material, shape or application.

By material

Alumina components for insulation, heat and wear; zirconia components for tougher precision wear and sliding contact.

By shape

Rods, tubes, pins and sleeves, plus rings and seal components.

By process

Drawing review and precision finishing for functional features.

By application

Typical uses in sealing, insulation, machinery, thermal equipment and fluid handling.

By material decision

Use the alumina versus zirconia guide to frame early questions.

By RFQ readiness

Follow the drawing and specification checklist before submitting.

Procurement Path

A simple route from problem to quotation

Choose a starting point

Material, shape, application or existing failure.

Share the drawing

Mark critical features and current revision.

Review manufacturability

Align geometry, tolerance, finish and ceramic choice.

Confirm quote scope

Prototype, inspection, repeat quantity and delivery needs.

For suitable features, an approximate 0.01 mm tolerance can be reviewed. The decision depends on material, geometry, size, accessibility, finish and measurement method.
