Start With the Function
We Build the Ceramic Part Around What It Needs to Do
Custom ceramic design works best when the drawing is supported by the actual load, temperature, media, electrical and wear conditions of the assembly.
Requirement 01
Electrical Isolation
Components designed to separate conductive parts while maintaining geometry under clamping, heat or repeated operation.
Requirement 02
Wear & Friction Control
Hard ceramic interfaces for sliding, guiding, abrasion or repeated contact where service life matters.
Requirement 03
Fluid & Chemical Service
Custom ceramic components for pumps, valves, nozzles and process equipment exposed to aggressive media or precision flow.
Requirement 04
Thermal & Precision Duty
Parts developed for temperature stability, controlled geometry and repeatable performance in demanding equipment.
Custom Component Range
Custom Shapes for Real Industrial Assemblies
Standard ceramic shapes can be adapted with application-specific dimensions, interfaces and secondary features to fit your equipment.
Linear Components
Custom Ceramic Rods & Shafts
Precision diameters, straightness, journals, shoulders and working surfaces for guiding, rotation and mechanical interfaces.
Flat Components

Flow Components
Custom Ceramic Nozzles & Flow Parts
Custom orifices, bores, seats, passages and outlet geometries for precision flow, abrasive media and chemical service.
Engineering Approach
Custom Ceramic Parts Should Be Specified by Function, Datum and Critical Interfaces
Ceramic components perform best when the drawing makes a clear distinction between functional dimensions and non-critical geometry. This helps concentrate precision where it creates value.
Functional Datums
Identify the surfaces or axes that locate the component in the final assembly and control dimensional relationships from those references.
Critical Interfaces
Mark bearing fits, sealing faces, sliding bores, electrical isolation zones or mounting surfaces that directly affect performance.
Load Path
Show where compression, bending, impact, clamping or contact enters the component so geometry can avoid unnecessary stress concentration.
Service Conditions
Temperature, media, speed, pressure, wear and electrical requirements help determine the most suitable ceramic and finishing route.
Custom Geometry
From Simple Profiles to Multi-Feature Precision Components
Custom ceramic components can combine basic shapes with precision features when the design clearly defines what is functionally important.
OD / ID / Thickness Control
Steps / Shoulders
Holes / Slots / Pockets
Flats / Grooves
Chamfers / Radii
Concentricity / Runout
Flatness / Parallelism
Ground / Lapped / Polished Surfaces
Material Direction
Select the Ceramic Around the Application, Not Just the Drawing
Two components with identical geometry may need different ceramic materials because the operating environment, load and interface conditions are different.
Alumina
A practical choice for electrical insulation, wear resistance, dimensional stability and a wide range of industrial components.
Zirconia
Useful where higher toughness, impact resistance or resistance to local mechanical damage is important.
Silicon Nitride
Relevant for demanding mechanical, rotational or thermal-shock applications requiring strong performance at lower density.
Specialized Ceramics
Aluminum nitride, boron nitride and other technical ceramics can be considered when thermal, electrical or process-specific requirements drive the design.
Design for Ceramic
Three Issues Worth Reviewing Before the Drawing Is Released
A small design change can often make a ceramic component easier to manufacture and more reliable in service without changing its core function.
Sharp Stress Concentrations
Sharp internal corners, abrupt section changes and hard contact points can concentrate stress. Radii, chamfers and smoother transitions are often preferable where the function allows.
Unnecessary Tight Tolerances
Applying the same tight tolerance to every dimension increases manufacturing complexity. Critical fits and interfaces should be separated from non-critical geometry.
Ignoring the Mating Parts
Ceramic components should be reviewed together with shafts, housings, fasteners, seals and contact surfaces so fit and load conditions are realistic.
Applications
Custom Ceramic Components for Demanding Equipment
Custom ceramics are used when conventional materials cannot provide the required combination of wear resistance, insulation, chemical stability, thermal performance and dimensional control.
Semiconductor Equipment
Precision insulating, positioning and wear components for clean, electrically controlled and dimensionally sensitive assemblies.
Pumps & Fluid Handling
Sleeves, bushings, plungers, pistons, nozzles and valve interfaces for wear, corrosion and precision-flow duties.
Electrical & Electronic Equipment
Custom insulating parts, supports and interfaces where dielectric stability and geometry must work together.
Industrial Machinery
Wear parts, guides, shafts, spacers and supports used in repetitive motion, alignment and high-contact applications.
Vacuum & Process Equipment
Custom technical ceramic components for controlled environments where contamination, heat or chemical stability matter.
Laboratory & Analytical Systems
Precision components for sample handling, thermal processing, measurement and specialized instrument assemblies.
Quality & Inspection
Inspection Follows the Functional Drawing
The inspection plan should focus on the dimensions and geometric relationships that control fit, movement, sealing, insulation or contact performance in the final assembly.
Critical dimensional inspection
Flatness / straightness / roundness
Concentricity / runout review
Surface roughness inspection
Edge and visual integrity checks
Custom inspection reports by agreement
Custom Manufacturing
Send the Drawing Together With the Real Working Conditions
The fastest way to evaluate a custom ceramic component is to combine the drawing with application details. This gives engineering enough context to review material, geometry, critical tolerances and finishing requirements together.
FAQ
Custom Ceramic Component Questions
Can UNIPRETEC manufacture ceramic parts from our drawing?
Yes. Custom ceramic components can be evaluated from 2D drawings or 3D models together with the required material, tolerances, surface conditions and application details.
Can you help select the ceramic material?
Yes. Material selection can be reviewed around the working temperature, electrical requirements, wear, chemical exposure, load and mating conditions of the application.
Can ceramic parts include holes, grooves, steps and precision surfaces?
Custom features can be evaluated according to the selected ceramic, feature geometry and manufacturing route. Critical surfaces and transitions should be identified clearly on the drawing.
Can you support prototype quantities before production?
Prototype and trial quantities can be discussed during engineering review, followed by production planning once the design and functional requirements are confirmed.
What information is needed for a custom ceramic quotation?
Send the drawing or model, material preference, critical tolerances, surface requirements, application conditions, mating-part information and expected quantities.
