Microparts with Macro-Properties

OxiMaTec

The micro injection molded parts of high-performance ceramics are manufactured according to a detailed processing specification (figure: OxiMaTec)

Plastic moldings are often pushed to their limits in applications in which they are subject to severe thermal, mechanical or tribological conditions. In such areas, the exception properties of high-performance ceramic moldings come into effect. This class of materials, too, can be processed into parts with complex geometries and delicate structures.

Unlike plastic injection molding, injection molding of ceramics is a multistage process. After compounding, the ceramic powder must first be made injection moldable by means of a binder system. The injection molding process itself is followed by two further process steps – debindering and sintering, in the course of which the additives necessary for injection molding are removed again and the part is consolidated into its final structure. The end part still has about 50 % of the volume of the green compact. The formulations and processing parameters for such high-performance ceramic parts are developed by OxiMaTec GmbH, Hochdorf, Germany.

At Fakuma, OxiMaTec is not only presenting finished parts, but also a portion of the manufacturing process, injection molding of the green compacts. The company is focusing on the manufacture of ceramic micro parts (Fig.). A marginal detail is that these parts very probably have a longer lifetime than the product they are installed in.
