Every year, the EVS (Electric Vehicle Symposium) is the major international event to address all areas for improvement of the future of electric mobility. Various topics concerning electric mobility will be discussed : the different means of transport, equipment manufacturers, car manufacturers, charging facilities, etc.

The 35^th edition will take place this year in the city of Oslo in Norway from 13^th to 15^th june 2022. The city of Oslo is one of the world’s most involved cities in the development of electric mobility with the highest global rate of electric vehicles per capita.

We will participate again in this event as an exhibitor on the stand of the CARA automotive cluster. The 14^th june 2022 in Hall C at 4pm. We will present all the solutions we offer for electric mobility, In particular our know-how in the design and manufacture of lightweight aluminum battery pack structures integrating thermal management.

Come and meet us at the CARA stand located in the French pavilion C01 – 14 during these three days.

Aluminium welding and assembly line for the prototype production of battery trays and modules structure to go in production.

Ilsfeld 16.12.21 – Saint Jean Industries Stuttgart GmbH is upgrading and further expanding its commitment to electric mobility. A new production line is specifically designed for the prototype production of battery trays and modules structures, and subframes in aluminium hybrid construction. The setup of such a production line is another milestone in the company’s consistent orientation towards the needs of e-mobility.

The Saint Jean Group as a chassis and aluminium lightweight construction specialist from France and Tier 1 supplier with 9 plants worldwide in Europe, the USA and China has already been active for over 30 years. With its existing production capacities, Saint Jean Industries Stuttgart GmbH, located in the immediate vicinity of Heilbronn, is able to produce battery carriers with dimensions of up to 3,000 mm in length at short notice.

In the production line, the extruded profiles machined in-house are further processed with all types of castings, including those from the Saint Jean Industries Group, and finished by means of welding, bonding and the latest joining techniques to form the subassembly into the ready-to-install solutions. The prefabrication of subassemblies is carried out by a new robot welding cell that is specially designed for this purpose. The additional welding capacity helps to shorten the throughput times for the prototypes and increases the production capacity in this area.

At IAA 2021, several vehicles were already presented whose battery trays and modules structure came from the prototype line of Saint Jean Industries Stuttgart GmbH. Apart from accomplished passenger vehicles, production is currently underway for vehicles from the commercial vehicle sector.

At the Ilsfeld site, which was founded in 1992, Saint Jean Industries Stuttgart GmbH produces assemblies in aluminium lightweight construction for the automotive industry. The focus is on battery trays, modules structures, subframes and safety-relevant assemblies for the crash areas of vehicles in series production. In principle, series of 1 – 50,000 vehicles per year can be produced, and even more depending on the project. Customers include a number of well-known OEMs in southern Germany, but also various sports car manufacturers in the immediate vicinity as well as in Italy and England.

The battery is undeniably the key element of electric mobility. Its weight and price make it the main subject of research and innovation at the moment and for many years to come. And the event “Batteries event”, which will be held in the “Cité internationale” building of Lyon from September 29 to October 1, 2021, is a must to follow the trends and the projects in progress on the subject.

Saint Jean Industries will be present to show how it accompanies the innovation of batteries. The main topics will be lightweighting, safety and thermal management. All of SJI’s efforts are geared towards optimizing the autonomy of electric vehicles. All the production means, whether aluminum casting, extrusion, forging, machining, assembly and many others, are combined to offer the best solution for the battery pack structure. We will talk about the InnoTherMS project and its latest developments.

Join us at this 23rd edition!

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!
