Common Industrial Ceramic Part Problems We Help Solve
Custom ceramic parts are hard, brittle, and difficult to machine. Small issues in material selection, edge design, grinding, tolerance control, or surface finish can lead to cracking, chipping, poor fit, and short service life.
We help improve ceramic part performance through proper material selection, precision grinding, controlled edge treatment, and careful dimensional inspection.
01
Edge Chipping & Micro-Cracks
Ceramic parts may chip or crack during machining, assembly, or use, especially on thin walls, sharp corners, holes, and small features.
- We review the part structure and apply proper grinding, chamfering, and edge protection to reduce chipping risk.
02
Poor Fit & Tolerance Issues
Ceramic components often work with metal parts, shafts, fixtures, sensors, or insulation systems. Small dimensional errors can cause assembly problems or unstable performance.
- We control key dimensions, hole positions, flatness, roundness, and matching surfaces based on your drawing requirements.
03
Wrong Ceramic Material Selection
Different ceramic materials have different properties. Alumina, zirconia, silicon nitride, and silicon carbide are not suitable for the same working conditions.
- We help review your application, wear, temperature, insulation, corrosion, and strength requirements before choosing the material.
04
Rough Surface & Wear Problems
Poor surface finish may increase friction, particle buildup, wear, or damage to matching parts during long-term use.
- We support precision grinding, polishing, surface finishing, and inspection to improve surface quality and working stability.

Case Presentation
FAQs
How long does Sundi MFG need to deliver custom industrial ceramic parts?
The typical lead time is 7–20 days after the drawing, material, tolerance, quantity, and processing requirements are confirmed.
For complex ceramic parts, tight tolerance parts, or parts requiring molding, sintering, grinding, and polishing, the lead time may be longer.
What ceramic materials can you provide?
We can support common industrial ceramic materials, including alumina ceramic, zirconia ceramic, silicon nitride, silicon carbide, aluminum nitride, and magnesium oxide.
The suitable material depends on your application, such as wear resistance, insulation, high temperature, corrosion resistance, or mechanical strength.
Can you manufacture ceramic parts according to drawings?
Yes. We can manufacture custom ceramic parts based on 2D drawings, 3D files, samples, or application requirements.
To quote accurately, please provide the material, size, tolerance, quantity, surface finish, and working conditions if available.
Can ceramic parts be machined to tight tolerances?
Yes, but the achievable tolerance depends on the material, size, structure, and machining method.
Ceramic materials are very hard and brittle, so tight tolerance parts usually require precision grinding, ID grinding, cylindrical grinding, polishing, and careful inspection.
What types of ceramic parts can you manufacture?
We manufacture custom ceramic rods, tubes, plates, sleeves, pins, nozzles, guides, spacers, insulators, sealing rings, wear parts, and other precision ceramic components.
These parts are widely used in pumps, valves, filling equipment, electrical systems, automation equipment, grinding devices, and industrial machinery.
Can you help choose the right ceramic material?
Yes. If you are not sure which ceramic material is suitable, you can share your drawing, sample, working temperature, contact material, wear condition, and application details.
Our team can help review whether alumina, zirconia, silicon nitride, silicon carbide, or other ceramic materials are more suitable.
Can you make ceramic parts from samples without drawings?
Yes, in some cases we can review samples or photos first.
However, drawings are strongly recommended because ceramic parts often require clear tolerance, surface finish, hole size, edge design, and assembly requirements.
Can you provide inspection reports?
Yes. Inspection reports can be provided according to your project requirements.
We can check key dimensions, holes, outer diameter, flatness, roundness, surface finish, appearance, cracks, chips, and other important features before shipment.
