For many years, a development cooperation in the field of tempering structural cast components exists between Audi and Tenova LOI Thermprocess. The modular design of the new heat treatment plant was jointly developed according to Audi’s specifications. This plant consists of a furnace for solution annealing and aging treatment, a fluidized bed furnace and a quenching device that can be operated with air or water.
“The LOI heat treatment plant represents an important section in the Audi-Technikum since it is responsible for ensuring the crucial mechanical properties (stability, ductility) of the products”, said Erik Micek, CEO of LOI Thermprocess GmbH. “We are particularly proud of cooperating with Audi to develop highly flexible process designs that allow Audi to carry out investigations in multiple directions”.
The newly developed quenching device represents a novelty with the achievable range of cooling gradients. It is a beneficial precondition for Audi in Neckarsulm to develop in detail new parts of different manufacturing processes and alloys which prove to be suitable for later series production.
“The material development represents the basis for the successful light-weight chassis construction in the Audi works in Neckarsulm. The innovative materials increase the efficiency of our models and are thus an essential components towards electromobility”, explains Helmut Stettner, Plant Manager, Audi site Neckarsulm.
Both partners continue elaborating further trend-setting solutions with the aim to optimize the process guidance and the component properties in the production of lightweight construction parts.
