This guide explains what to prepare before asking for a quote for alumina, zirconia or other technical ceramic components. A complete inquiry helps reduce back-and-forth messages, avoids wrong material selection and makes pricing more accurate.

1. Send a Drawing, 3D File or Sample Photo

A 2D drawing is the best starting point because it shows dimensions, tolerances and important surfaces. A 3D file is helpful for complex shapes. If there is no drawing, a clear photo with measured dimensions can still start the discussion.

  • Accepted references: PDF, STEP, IGES, DXF, DWG, JPG or PNG.
  • Mark critical dimensions and surfaces if only part of the component needs tight tolerance.
  • For replacement parts, include photos from several angles and a ruler or caliper reference.

2. Describe the Working Condition

Ceramic material selection depends on more than size. Temperature, load, friction, chemicals, voltage and assembly method can change the best material choice.

If you do not know the ceramic grade, explain the problem: wear, heat, insulation, corrosion, sticking, deformation or metal contamination. HERUN can suggest a practical starting material.

3. Choose Material or Ask for a Recommendation

Many custom parts are made from alumina or zirconia. Alumina is commonly used for insulation, heat resistance and cost-effective wear parts. Zirconia is commonly used when toughness, smooth surface and precision wear behavior are important.

If your application requires silicon carbide, silicon nitride or another advanced ceramic, send the working condition and target quantity so feasibility can be checked before quoting.

4. Define Tolerance and Surface Finish

Technical ceramic parts are hard after sintering, so tight dimensions are usually made by diamond grinding. Polishing, lapping and very tight tolerance increase cost. If a surface is not functional, it should not be over-specified.

  • Tell us which dimensions are critical.
  • Mark sliding, sealing, insulating or assembly surfaces.
  • Give roughness requirements only where they matter.

5. Share Quantity and Target Use

Prototype quantity, pilot batch and repeat production are quoted differently. For example, one difficult prototype may be dominated by setup and grinding cost, while a stable batch can be optimized through forming and production planning.

Typical useful details include annual quantity, first trial quantity, target delivery time and whether samples must be approved before batch production.

What Happens After You Send an Inquiry?

  1. HERUN checks drawing, geometry, material and manufacturing feasibility.
  2. We confirm any missing details such as tolerance, surface finish or quantity.
  3. You receive material suggestion, price, lead time and next-step questions if needed.
  4. For custom OEM parts, samples can be made before batch production.
