The Trempelec company, a subsidiary of the ThermiLyon group and specialized in heat treatment solutions, announced the inauguration of a new vacuum heat treatment line in the Arve valley, in Haute-Savoie.
This infrastructure, the first of its type in the region, represents an investment of more than 3 million euros and is based on advanced low-pressure carburizing technologies to meet the needs of the automotive and precision engineering industries. This new treatment line Tremplec incorporates a “4 in 1” multifunctional oven, capable of carrying out different types of heat treatments. It is equipped to carry out gas quenching, vacuum quenching with oil, low pressure carburizing with gas quenching, and low pressure carburizing with vacuum quenching with oil. This flexibility makes it possible to process a wide variety of parts in series, while optimizing the quality of the heat treatment.
The low pressure carburizing used generates a thin metallurgical layer, without carbides or internal oxidation, ensuring uniformity of treatment. The process is controlled with a precision of +/-5°C, ensuring reliable and reproducible results even for complex shapes. To minimize part distortion, the line uses a neutral gas quenching cycle and, if necessary, vacuum oil quenching for even further reduced distortion.
A commitment to a carbon-free industry
The new line contributes to reducing the industry’s carbon footprint by using electric power instead of gas. The vacuum technology of this system significantly reduces energy consumption and limits CO² emissions, thus supporting decarbonization efforts. By optimizing energy performance, Trempelec meets today’s growing environmental expectations.
The line is particularly suitable for the production of large series parts for demanding applications, such as transmission components, injection parts for thermal engines, and power steering elements. With a maximum load capacity of 750 kg, each cell of the multi-cell furnace can be configured to meet specific customer needs, ensuring compliance with AMS2750 and CQI9 standards for heat treatment.
