Your Engineering Ceramic Manufacturer for Custom Industrial Components
We manufacture high-purity ceramic products with custom diameters, tight tolerances, and stable quality for industrial applications.
Your High-Performance Engineering Ceramic Solutions Provider
KosRemic is committed to providing OEM/ODM customers with one-stop ceramic machining service solutions for high-performance engineering ceramics.
We are equipped with high-temperature sintering ceramics, ceramic grinding, forming, drilling, surface treatment, and double-side grinding capabilities, enabling us to produce a wide range of custom ceramic parts.
We can perform high-precision double-side ceramic grinding, fine mechanical polishing, coating, laser texturing, and sandblasting surface treatments on alumina, zirconia, silicon nitride, and other ceramic parts.
In addition, based on your requirements such as high sealing performance, wear resistance, or metal integration, we can develop tailored solutions through precision ceramic machining.
How It Works
Injection molding, tape casting, pressureless sintering ceramics, laser cutting, centerless ceramic grinding, and precision polishing are part of our ceramic fabrication processes, helping transform your design into real custom ceramic parts.
Forming Technologies
Dry pressing
Cold isostatic pressing (CIP)
Injection molding
Tape casting
We select forming technologies based on your design requirements such as size, wall thickness, complexity, and production volume.
For example, large components above Φ100mm are typically processed using CIP as part of ceramic machining optimization.
Sintering Technologies
Pressureless sintering
Atmosphere sintering
Hot isostatic pressing (HIP)
Our factory is equipped with high-temperature pusher kilns, shuttle kilns, hydrogen furnaces, and nitrogen furnaces to precisely control shrinkage during sintering ceramics.
Cutting and separation technologies:
Diamond dicing / Diamond wire cutting / Laser cutting
Precision grinding technologies:
Surface grinding / Cylindrical grinding / Internal grinding
(ceramic grinding)
Precision lapping and polishing technologies:
Double-side grinding / Mechanical polishing / Chemical mechanical polishing (CMP)
(ceramic grinding)
If you require a better surface finish, KosRemic can polish the cutting edges and formed surfaces of alumina ceramic parts, achieving high precision and surface smoothness through precision ceramic machining.
Ceramic CNC Machining
Double-side grinding / Mechanical polishing / Chemical mechanical polishing (CMP)
When your design includes complex features such as holes, grooves, threads, or curved surfaces, our five-axis ceramic cnc machining equipment and ultrasonic machines can transform complex geometries into actual custom ceramic parts.

Custom Ceramic Solutions for Industrial Applications
KosRemic: Manufacturing
We have more than 10,000 square meters of factory space, equipped with various production equipment. With our professional in-house manufacturing capabilities, your design can be transformed into products.
Before the real production, our product manager can support you optimize the design for cost reducation and real production . For example, if non-critical parts require 99.9% high-purity alumina, we will evaluate your actual working conditions (such as temperature, corrosion, insulation requirements etc). If 95% or 99% alumina ceramic can meet these requirements, we will downgrade the material accordingly, and the material cost can be reduced by about 30%.
How We Control Your Quality
At KosRemic, every step—from raw material selection to final inspection—is strictly controlled to ensure consistent performance and reliability of all ceramic components.
Our team will control your fabrication quality from incoming raw material inspection (IQC), in process quality control for each key process (IPQC) and Outgoing Quality Control (OQC). All inspection activities are according to your drawings and testing requirements.
We ensure every batch of custom ceramic parts undergoes thorough inspection before shipment
– Raw Material Inspection
– Controlled Sintering Process

The feedback From Our Customers:
Not only have you produced thousands of higher-quality alumina ceramic tubes for us, but your prices have also been reduced by 30%!
–George Miller Gensler
thanks you for having the five-axis CNC engraving machine to help us produce irregular-shaped ceramic rings. Previously, we collaborated with several suppliers, squandered over 50,000 US dollars, and the project almost failed.
–Nick Wyatt BOSH
is very grateful to you for adding Hexagonal Boron Nitride Coating to our ceramic tubes. For many years, we have been plagued by high temperatures. It was not until your appearance that we found a truly effective solution.
–Luis Torres Dorman
