Technical ceramics

The production of electro-ceramic products requires extremely high temperatures. Naturally, this raises the question of efficiency. Thus, in addition to reliability with regard to consistently high product quality, energy balance is also a main focal point. Our ongoing development work is based on the expertise gained in the course of designing and constructing many different systems – roller hearth kilns, tunnel furnaces, firing shelf furnaces, pusher plate furnaces, push-through furnaces, walking beam furnaces, lifting bottom furnaces and much more. If none of our systems meet the customer’s requirements, Eisenmann simply develops a custom-built system.

For example, the gas-tight and, if necessary, vacuum-tight continuous roller hearth kiln that allows for different furnace atmospheres in sequential phases of a thermal process. This is how, for example, in the sintering of powder metal components, the sequential zones are operated with different process gases according to process requirements.

A truly efficient production line can only be achieved with the perfect process flow solutions for linking the furnaces with upstream and downstream production. With our knowledge of furnace systems and wide range of conveyor and automation solutions, we’re able to create the perfect combinations of both and avoid interfacing problems.

The range of electronic elements in use is comprehensive. So are the answers of Eisenmann Thermal Solutions. For multi-layer varistors or ferrites, oxygen sensors or piezoelements. A detailed analysis of the requirements is the essential starting point for Eisenmann in order to offer tailor-made factories for debindering and sintering. Take the example of one renowned manufacturer of Lambda sensors that purchased a series of Eisenmann lifting bottom furnaces. Detailed solutions like recirculated-air operation during debindering ensure the fast but gentle expulsion of organic matter. Once it reaches 600 °C, the sintering chamber is closed, and the charge is heated electrically by means of ceramic heating elements. The bottom-loading design allows for a very compact structure and the use of a loading portal that services multiple furnaces in a row. The concept allows for fast changeover times with the additional advantage that the stored energy in the furnace bottom is optimally reused.

Whether you’re dealing with water or media filters, exhaust filters or catalyst carriers, ceramic components are generally bulky and delicate. This makes thermal process management extremely challenging. An optimal solution for debindering is the key to an efficient general concept. Eisenmann offers continuous furnace concepts that allow for highly efficient debindering of components with circulating air and a controlled atmosphere. In addition to excellent plant engineering, Eisenmann also offers professional project and site management. This is another reason why the world’s biggest manufacturers of filters and catalyst carriers in the automotive industry have come to rely on Eisenmann plants.
