The cluster CARA’s Automotive Techdays will take place the 1st of June 2021 for the first time online.

All the innovative companies in Rhône Alpes working for the future of mobility will attend. To better identify the different innovations projects and applications, 3 groups have been created:

• Energy
• Structure & Materials
• Sustainable Connected Mobility

Saint Jean Industries will participate in the “Structure & Materials” category to show one of its last innovation : the bi-material brake disk COBADISK. A unique technology taking advantages of the COBAPRESS ‘s mechanical properties in order to offer a lightweight and competitive product.

To get further information and receive the official invitation to attend, please contact us.

If you missed the 2020 german event “Leichtbau Gipfel“, it is still possible to see the replay of the Saint Jean Industries presentation about the bi-material brake disk for automotive: the COBADISK.

This innovative technology is simply surprising and a reliable braking solution. It combines aluminium and cast iron in their best usage to maximize the weight saving. That is why the center part of the brake disk, the hub, is made in aluminium thanks to COBAPRESS technology, a cast/forge technology used to get improved mechanical properties. And the brake disc track is made of grey cast iron with a specific design to make possible the assembly of the two parts.

The result: a brake disc with 25% of weight saving compared to cast iron monobloc, and the same level of performance. The design of the hub and track could be adapted depending on OEM requirement in term of braking resistance.

SJI Inc nominated as chassis supplier of the year 2020 for FCA North America! A great recognition for american colleagues from Heber Springs! Go Hogs! ?

This week was marked by the delivery of the first aluminum wheel carrier to the Chinese electric vehicle manufacturer Human Horizon.

Our plant in Changshu took up a major challenge: developing the new low-pressure aluminum casting line, heat treatment, X-ray inspection, machining and assembly of the wheel carrier in just two weeks. And it is a great success for the Chinese team after the difficult period of COVID-19 lived in the previous months. These first parts are the beginning of a long series.

Great job to the chinese team!
