Dietze Group precision furnaces for high-end, oxide-free quality
With the precision furnaces we developed in-house, we are especially suited to assist you with miniaturized parts, such as sensor packages. Compared to traditional belt furnaces, our equipment allows precise control of temperature and process-gas conditions. This prevents discoloration and contamination of parts, which is often seen in standard processes. Titanium parts, regarded as especially critical, can be produced completely oxide-free by our equipment, without the need to be chemically or mechanically post-treated.
Ceramics and Sapphires in combination with glass-to-metal seals
Apart from standard electrical feedthroughs, our processes additionally offer to hermetically integrate ceramic or sapphire parts into glass-to metal seals. This opens up new possibilities for various sensor applications (e.g. For optical process sensors or high-vacuum gauges).
Special technical glasses are employed in glass-to-metal sealing to match the chemical and CTE requirements of the application. These glasses are pre-produced as either sintered glass preforms or drawn glass tubes. Sintered glass preforms are created by pressing and sintering glass granulate. With this technique, custom geometries can be created, such as preforms for multiple-pin feedthroughs. However, a custom tool has to be created for each geometry and there are some limitations on wall thickness and length in relation to the diameter. Drawn glass tubes can be manufactured with a higher precision and thin walls are possible. They are, however, limited to “tubing” geometries.
The Dietze Group helps its customers with custom interconnection solutions from concept to series production. Our products are designed in close collaboration with our customers and engineered to meet the application’s specific needs.
