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.
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.
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.
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.
