Michelin’s Hungarian factory enters from the Age of Steam to the Electrical Age

A major development has been introduced at the Michelin plant in Nyíregyháza, Hungary. The sports car tire factory is modernizing its curing equipment by replacing the existing steam presses with electric ones, and thereby reducing its energy consumption.

Curing (or vulcanization) is the final stage in the tire manufacturing process, during which the tires are getting their final geometric form. The chemical reaction that creates cross-linkages between the polymer chains of the rubber compound takes place in curing presses holding the tire molds, under the influence of heat.

Michelin developed its first electric curing press in Germany in the early 2010s. This technology is considered unique as it is not typically used by other suppliers in the production of tires for passenger cars. In Germany, this first electric curing press was equipped with Siemens technology, and Michelin is implementing this control technology as company standard for all its factories for the installation of new presses.

Pilot project precedes the Hungarian development

Michelin installed the prototype of the electric curing press in Nyíregyháza in 2021, and in the following year, 6 new electric presses were commissioned in addition to the first one. Based on the positive experiences, the replacement of all 40 presses in the plant has begun in 2023, and all curing presses are scheduled to become electric by the end of 2024.

By replacing steam presses with electric production technology, the Nyíregyháza factory is expected to increase its energy efficiency by 7 times and move closer to achieving carbon neutrality by 2050 by reducing its environmental footprint and CO2 emissions.
