Customized High Temperature Isostatic Pressing Alumina Ceramic
Plates
Ceramic Pressing
According to your component requirement, there are several basis
forming methods such as hot press moulding technique, dry pressing,
Isostatic pressing, etc.
Isostatic Pressing is the use of force pressures of equal
proportion from all directions. Iso-pressing is commonly used to
form complex ID configurations by compressing powder around a pin.
Dry Pressing utilizes steel or carbide tooling that creates a "net
or near net" shape. By filling the tool with powder and applying
uniaxial pressures to compress the powder.
Ceramic Firing
In order to make ceramic hard and dense, they must be "sintered",
or fired to high temperatures for prolonged periods of time in gas
or electric kilns. Typical firing temperatures for alumina reach
1600 °C - 1700 °C.
Ceramics shrink approximately 20% during the sintering process.
Non-uniform shrinkage as a result of standard forming and machining
processes can cause deformation of the ceramic. Our experience and
knowledge of ceramic processing allows us to utilize specific
machining and firing methods to help limit these effects.
Ceramic grinding
Grinding is the most widely used method of machining of ceramics in
the sintered state. Diamond Grinding may be required to achieve
tight tolerances, and surface finishes.
Diamond tool for grinding is the key process to meet the drawing
requirement which is our strength. At this stage ceramic can only be machined with diamonds, so
tooling can be costly. Standard machine shop equipment can be
modified with diamond plated or impregnated wheels, drills and
assorted tools, as well as necessary recirculating and filtered
coolant systems.
Ceramic Packing
As a ceramic material, Alumina Plate is quite fragile in a lot of
cases. Our Alumina Ceramics are carefully handled to minimize
damage during storage and transportation. Suitable outer boxes and
inner cushioning materials are used, and vacuum packing is also
engaged for some of the parts.
