Ceramic Near Net Shape

In the past a ceramic component has been 2x to 5x more expensive than a comparable steel component.

Ceramic near net shape.

75 wt paraffin wax 25 wt microcrystalline wax and a small amount of additives is used for a solvent. Near net shapes al2o3 sicw ceramic nanocomposites produced by hybrid spark plasma sintering e. The name implies that the initial production of the item is very close to the final net shape reducing the need for surface finishing reducing traditional finishing such as machining or grinding eliminates more than two thirds of the production costs in some industries. Our comprehensive product line consists of metal and ceramic powders compounded with tailor.

Net shape manufacturing focuses on the manufacture of discrete parts to net or near net dimensions. 26th annual conference on composites advanced ceramics materials and structures. Catamold powder injection molding is the leading ready to use feedstock for metal and ceramic injection molding. To enable quick fabrication of high temperature advanced ceramics and metals quad city manufacturing lab qcml offers spark plasma sintering for near net shape processing of parts.

Spark plasma sintering sps is the process of consolidating metal and ceramic powders using high temperatures and pressures. Chamotte powder is used as an example of a ceramic. I ganesh fabrication of near net shape magnesium aluminate mgal 2 o 4 spinel components via aqueous processing advances in applied ceramics 10 1179 1743676110y 0000000020 110 8 496 511 2013. In this new process a low melting point wax.

Traditional ceramic machining requires diamond tooling and longer processing time. Machining when needed is a process step in ceramco s manufacturing reducing the complex ceramic part from the near net shape to its final tolerances. The possibility of absorbing dewax with fibrous absorbers papers cloths etc is examined in order to make ceramic articles in near net shape. Torrecillas abstract this article describes the process and demonstrates the possibility to obtain a complex square shaped nanostructured ceramic cutting composite by spark plasma sintering.

Multiple parts can be reduced to one. When machining is required it can occur at two points during the production process. Near net shapes by ceramic injection molding. As a result a ceramic metal matrix grows up through the preform leading to a dense ceramic metal composite.

High parts complexity is attainable. Near net shape fabrication high material utilization. That constitutes about 80 of the cost.
