Ceramics Manufacturing Process

Ceramics Manufacturing Process

This is how our fine ceramic parts are made.

Raw Material Mixture

PROCESS1

Raw Material Mixture

Refined, high-purity ceramic raw material is mixed with necessary binders and solvents, and ground with a ball mill to create a “slurry”.

Granulation

PROCESS2

Granulation

The liquid “slurry” is then granulated with a spray dryer. These granules have an average particle size of 80 micron.

Ceramic raw materials such as oxides, nitrides, carbides, etc., will be processed with additives like sintering aids, reinforcing and/or complexing agents, and forming aids, and then grinded, mixed and kneaded.

Molding

PROCESS3

Molding

The granulated powder is then placed into a rubber mold to be pressed by the CIP (Cold Isostatic Press) system with hydrostatic pressure.

Green Machining

PROCESS4

Green Machining

The CIP molding method presses the material into a rough shape, and so before sintering, green machining will be performed by calculating shrinkage from firing.

Sintering

PROCESS5

Sintering

The green machined fine ceramic material will be sintered in a gas or electric furnace, or depending on the material, vacuum furnace.
Sintered materials will be verified through cosmetic inspection, dimensional inspection and color check (penetrant check). Only conforming materials advance to the next process.

Secondary Machining

PROCESS6

Secondary Machining

This is the process where fired works are machined into the final product dimensions. We own surface grinders, rotary grinders, milling machines, cylindrical grinders, machining centers, etc. Since ceramics are the hardest material next to diamonds, diamond tools are used for processing ceramics.

Inspection

PROCESS7

Inspection

After machining, the products will be verified for compliance with drawings and specifications. Naked eye inspection will be performed to ensure no cracking or chipping exists. Dimensions are verified with 3-dimensional measurement equipment, calipers, and pin gauges.

ASUZAC is an ISO9001 certified company and performs inspections using traceable tools.

Cleaning ・Packaging ・Shipping

The products, after final inspection, will be cleaned according to our cleaning procedure and packaged in a cleanroom before being shipped to our customers.
