Autoneum signed an agreement to acquire 70 percent of the shares of Jiangsu Huanyu Group, a leading automotive supplier for acoustic and thermal management in China. Business Group Asia is thus expanding its customer base to include major Chinese vehicle manufacturers such as BYD, BAIC and GAC, and will significantly increase its annual revenue. The transaction is scheduled to close in March 2025.

With around 30 million light vehicles produced annually, China is the world’s largest automotive market and, with an expected increase to 32.4 cars in 2030, it is also one of the most important growth markets for the automotive industry. Established in 2001, Jiangsu Huanyu Group is today one of China’s leading suppliers of lightweight components for light and commercial vehicles. The company operates 14 production facilities with around 1 100 employees in the immediate vicinity of local automotive manufacturers in the north, west and southeast of China.

Jiangsu Huanyu Group’s product portfolio includes components for the vehicle interior such as carpets, inner and outer dashes, headliners, trunk and interior trim, wheelhouse outer liners as well as insulation for the engine bay and the underbody. Jiangsu Huanyu Group also supplies commer-cial vehicle manufacturers in China, supporting Autoneum’s strategic initiative to grow its truck business in China. Synergies in the areas of technology and purchasing will also contribute to the further development of Business Group Asia. In the 2023 financial year, Jiangsu Huanyu Group generated revenue of around CHF 130 million and is recording strong growth in 2024. It is planned to continue operating the company under the Chinese company name.

The acquisition of Jiangsu Huanyu Group will be done in two phases. The closing of phase 1, the takeover of a majority stake of 70 percent at a purchase price of around CHF 75 million (excluding cash and cash equivalents and debt), is expected in March 2025 after approval by the authorities. As for the acquisition of the remaining 30 percent of the share capital, phase 2, Autoneum has a call option, which can be exercised in 2028. This two-phase approach binds both the current shareholders and the employees in key positions and allows Autoneum, together with Jiangsu Huanyu Group, to continue and further develop existing business activities smoothly.

“Jiangsu Huanyu Group has broad customer access to the largest local vehicle manufacturers in China. With its plants in the key automotive hubs in China, the company is an excellent strategic addition to Autoneum and brings us a significant step closer to our medium-term target of generating 20 percent of Group revenue in Asia,” explains Eelco Spoelder, Chief Executive Officer of Autoneum. “The acquisition of the majority stake in Jiangsu Huanyu Group will strengthen our position in China, the world’s largest and fastest-growing market, both in the light and commercial vehicle business. This step not only gives us access to an established customer base in China, but also allows us to further expand our presence and gain strong influence in the booming automotive hubs of Anhui and Shaanxi.”

• Autoneum is expanding its production capacities in Asia with two new plants in Changchun in the Chinese province of Jilin and Pune in Western India.

The world's largest automotive market Asia is one of the most important sales regions for vehicle manufacturers and suppliers as well as a pioneer for new forms of e-mobility. Autoneum already supplies both international and local vehicle manufacturers in Asia with multifunctional lightweight components for noise and heat protection, supporting them in their commitment to sustainable mobility. Autoneum is expanding its production capacities in the key automotive hubs of China and India to increase its presence and thus its proximity to customers in these important production centers.

Autoneum’s new plant in China, which will be operated as a joint venture, will be located in Changchun in the northern Chinese Jilin province, which is one of Asia’s largest car production centers. The proximity to key local and international vehicle manufacturers makes Changchun a strategically important and attractive location for Autoneum. The plant will help to increase market share with European, Japanese and Chinese car manufacturers with products for light vehicles and also support the expansion of the Company’s business with components for commercial vehicles in this region. The project is supported by the local authorities in China. From the end of 2024, the plant will ramp up production with first samples for already awarded business for inner dashes, interior floor insulators and other NVH (noise, vibration, harshness) components for cars of all drive types.

Autoneum is furthermore expanding its local presence in Western India with a fully owned production facility in Pune in the state of Maharashtra. The Company already operates two locations in India: one in Behror near New Delhi in the north and a joint venture plant in Chennai in the south. Thanks to the new Pune plant, Autoneum will now be present in the north, west and south of the country and gain access to the third of four major automobile production centers in India. Orders have already been received and the plant in Pune will start manufacturing carpet systems, interior trim, wheelhouse outer liners, e-motor covers and other noise protection components as of the second quarter of 2024. From the 7 500 square meter building, Autoneum will supply international as well as local car manufacturers with a particular focus on Indian and Korean vehicle manufacturers.

Production and care, logistics and agriculture – people in these and many other industries work hard day after day. Exoskeletons offer them enormous relief in this regard. And in rehabilitation, these innovative "power suits" help patients expand their motor capabilities and extend their mobility. The central component of the exoskeleton is elastic narrow textiles.

Every gram counts
Exoskeletons also require lightweight components. And every gram counts here. Textiles are particularly light materials in themselves and JUMBO-Textil's elastics are also suitable for replacing heavier parts made of or containing plastic or metal. For example, they replace springs, buckles or other fasteners.

Good for your back – and your skin
Exoskeletons need skin-friendly components. Depending on the model and ambient temperature, exoskeletons are also worn directly on the skin. This is why JUMBO-Textil does not compromise when it comes to wearing comfort: whether elasticated hook-and-loop belts or slip-proof woven tapes, the surface of the textiles is pleasantly soft. And to prevent moisture accumulating, the textiles are always permeable to air. They are free from harmful substances and meet OEKO-TEX Standard 100 PK1.

Innovative production technology – complex textile architecture
Exoskeletons need safe and stable components. JUMBO-Textil's production technology is always state-of-the-art. This allows for very different, and complex stable textile structures – from elastic buttonhole braids to multi-branched elastic hole cords.

• Composites in the construction industry - The lightweight construction material of the future

Building with fibre-reinforced materials opens up completely new possibilities. In terms of engineering, design, and organisation. This is due, on the one hand, to the excellent properties of fibre-reinforced materials (FRM) and, on the other hand, to the fact that the material – unlike wood or brick, for example – is not machined or processed for its use, but custom-produced.

Excellent properties – in terms of engineering, design, and organisation
Fibre-composite materials offer a whole range of technical properties for innovative and sustainable building:
•    High mechanical rigidity
•    Low weight
•    High corrosion resistance
•    Low material fatigue
•    Low heat transfer coefficient of the plastic matrix
•    Resistance to frost and de-icing salt
•    Good draping capability

In addition, fibre composites offer numerous design options for novel and exceptional new building and maintenance projects:
•    Unique variety of shapes
•    Different structures of the textiles
•    Large spectrum of colours and colour combinations
•    Translucency of the plastic matrix
Thanks to these properties, composites can be used to produce coloured, phosphorescent, thermochromic or – through the use of LEDs or light-conducting fibres permanently integrated into the matrix – luminescent components.

In addition, there are organisational benefits for planning, construction and maintenance work with fibre-reinforced materials:
•    Easier handling and assembly of the far lighter and more flexible components – compared with steel, concrete or wood
•    Faster installation
•    Shorter construction site times in road and bridge maintenance
•    Shorter delivery times
•    Ability to integrate electronic monitoring systems

Individual composite textiles – for every lightweight engineering project
The composites experts at vombaur develop and manufacture woven tapes and seamless round or shaped woven textiles from carbon, glass, flax or other high-performance fibres on special weaving lines for individually specified round and shaped woven textiles – and can therefore offer you the best possible fibre base for every lightweight construction project.

"Regardless of whether it's a new construction or a renovation project, a façade design, a bridge or a staircase – as your development partner for composite textiles, we have plenty of experience with composites for demanding tasks," emphasises Dr.-Ing. Sven Schöfer, Head of Development and Innovation at vombaur. "We develop, create samples and manufacture woven tapes and seamless round or shaped woven textiles – in collaboration with the customer enterprise development teams and individually for the respective projects." This is how novel and unique lightweight components made of high-performance textiles are created for visionary projects.
