Ceramic Manufacturing & Precision Machining
Precision ceramic components are manufactured through a controlled sequence of ceramic processing and post-sintering machining. Our manufacturing process can include:
Material Preparation → Forming → Sintering → Precision Machining → Surface Finishing → Inspection → Packing & Delivery
Depending on the component, manufacturing may involve:
- Ceramic forming
- Controlled sintering
- Diamond grinding
- CNC machining
- Drilling and hole machining
- Internal and external grinding
- Double-side grinding
- Lapping
- Polishing
- Cutting and slot machining
- Final dimensional inspection
The actual process route is determined by the ceramic material, component geometry, dimensional requirements, surface finish and production volume.
From Prototype to Repeat Production
Ceramic components often require several rounds of engineering adjustment before entering stable production. We can support customers through different stages of product development.
Initial samples for evaluating material, geometry, machining feasibility and functional requirements.
Suitable for equipment development, design verification and early-stage production.
Process control and inspection requirements can be established around approved drawings and specifications for recurring orders.
For repeat components, manufacturing parameters and inspection requirements can be managed according to the approved production standard.
Most precision ceramic components we manufacture are customized rather than standard off-the-shelf products.
Full-process Quality Control
We are an ISO 9001 certified company, and we implement integrated and strict control over the entire production process. From raw materials to manufacturing to shipment, every stage of production undergoes multiple inspection procedures—including incoming material inspection, first article inspection, self-inspection, mutual inspection, patrol inspection, and final inspection—to ensure quality compliance.
High-precision Machining Equipment
We are equipped with high-precision machining equipment such as CNC lathes, grinders, milling machines, drilling machines, polishing machines, and cutting equipment. We select appropriate equipment and machining technologies based on the requirements of the ceramic parts, ensuring both production efficiency and high-quality machining. For example, in grinding, the processes we commonly perform include flat grinding, cylindrical grinding, internal grinding, and centerless grinding.
High-precision Testing Instruments
We are equipped with high-precision testing instruments such as electron microscopes, optical measuring machines, coordinate measuring machines, height gauges, surface roughness testers, densitometers, laser grain analytical instruments, coating thickness gauges, mechanical strength testers, and resistance meters. These instruments can accurately measure the dimensions, surface quality, mechanical properties, and other parameters of ceramic parts, ensuring that products meet design requirements.

We manufacture components from alumina, zirconia, silicon nitride, aluminum nitride and other advanced ceramics, depending on the component and application. Material suitability should be evaluated together with geometry and machining requirements.
Tolerance capability depends on material, component size, geometry, feature location, machining process and inspection method. Tight tolerances can be supported for selected features after engineering review rather than being applied universally to every ceramic component.
Yes. Depending on the component, we can use grinding, lapping and polishing to meet specified surface requirements. Fine finishes such as Ra ≤ 0.1 μm may be achievable on selected surfaces after engineering review.
We can evaluate components with holes, slots, grooves, steps, internal features and other complex geometries. Feasibility depends on the ceramic material, geometry, dimensions, machining accessibility and required tolerances.
Delivery time is related to the complexity of the parts, materials, and process requirements. Here is our approximate timeline.
1. Prototyping Stage
Simple standard parts: About 2-4 weeks.
Medium complexity parts: About 4-6 weeks.
High complexity/Initial production: About 6-8 weeks or longer (including design collaboration and multiple trial productions).
2. Mass Production Stage
After sample confirmation, our standard lead time for mass production orders is generally 4-8 weeks. The specific lead time depends on the order quantity and production capacity schedule.
We support your needs during the product development and validation phases. For larger products, the minimum sample quantity can be 1 piece. But if the size is small, producing a single sample is difficult and costly. Therefore, we will have a MOQ requirement (the specific quantity is determined based on demand).
The MOQ for bulk orders needs to be specifically assessed, but generally, the order amount should be no less than USD 150.
