Precision alumina and zirconia ceramic components for industrial OEM customers worldwide.
HERUN Ceramics focuses on precision alumina and zirconia components for demanding industrial applications. We support standard parts, custom drawings, small precision parts, insulating ceramics and wear-resistant components.
Our production workflow covers material selection, forming, sintering, CNC diamond grinding, lapping, polishing and dimensional inspection. Customers work with one accountable supplier from sample review to batch production.
We serve OEM buyers who need consistent quality, practical engineering support, reliable lead times and direct communication with the factory team.
Over 15 years of focused ceramic manufacturing experience, growing from alumina specialist to 4-material advanced ceramics supplier.
Export record spanning North America, Europe, Japan, South Korea, and Southeast Asia. Experienced with customs documentation and import compliance.
Current catalog uses real alumina and zirconia photos first. More material categories will be added after matching product images are ready.
Alumina and zirconia are active on the website now. More material categories can be restored after matching product photos are uploaded.
Standard products ship in 7–15 working days. Prototypes and custom parts in 20–35 working days. Express air freight available.
Lapping capabilities achieve tolerances suitable for ABEC bearing grades. CNC grinding to ±0.005mm as standard on precision parts.
Every operation from powder to finished part is performed under our roof — giving you a single accountable supplier for quality and lead time.
Controlled powder preparation with certified raw materials. Particle size analysis and batch traceability records maintained for every production run.
Dry pressing, isostatic pressing, and extrusion forming methods. Near-net-shape production minimises machining allowance for complex geometries.
Computer-controlled sintering furnaces for alumina and zirconia components. Process records and density checks support consistent batch quality.
Diamond wheel CNC grinding centres for OD/ID, surface, and profile grinding. Tolerances to ±0.005mm routinely achieved for standard dimensions.
Single-side and double-side lapping for flatness ±0.001mm. Polishing to Ra ≤0.05μm for seal faces, bearing races, and optical-quality surfaces.
CMM dimensional inspection, surface profilometry, and material testing. Dimensional reports and material certificates issued with every shipment.
Our quality management system governs every stage from raw material receipt to final shipment.
Certified quality management system covering design, production and inspection of technical ceramic components.
Certified raw material specifications and batch traceability provided on request for all production orders.
Full dimensional inspection report with actual measurements, CMM data, and pass/fail status for critical dimensions.
All standard ceramic materials are RoHS compliant. Declaration of conformity available for EU electronics market requirements.
The website currently presents the materials with real product photos available: alumina and zirconia.
The industry workhorse. Best cost-performance ratio for electrical insulation, wear resistance, and chemical inertness. Widest range of standard sizes. Fastest lead times.
Highest toughness and biocompatibility. Ideal for medical devices, precision pumps, and thermal break applications. White appearance suitable for consumer-facing products.
