Worldwide production competence Dual strategy for success

Central to the corporate branding of SMS group are production of core components and pre-assembly in our own workshops. Included here are not only our German facilities in Hilchenbach and Mönchengladbach, but also a continually growing network of international workshops. To ensure top final product quality, we will continue to manufacture know-how-intensive core components in Germany.

Our plants in China and India produce special products as well as solutions tailored to individual markets. You and your partners benefit from our expanding local presence that gives you fast, fuss-free service wherever you are. We remain focused on our role as a global technology leader shaping the future with design and manufacturing excellence. Optimized work flow processes and efficient production solutions ensure shorter lead times so you get top quality, reliable, and high-performance products.


Extensive production know-how Cornerstones for highest customer satisfaction
Design and manufacturing under one roof image

Under one roof
A stand-out feature of our Hilchenbach and Mönchengladbach locations is the direct interaction between engineering and manufacturing. This naturally facilitates a continuous exchange of ideas between these departments for ongoing optimization of our products.

Qualification and training

Expertise makes all the difference
Key to meeting your requirements is the skill of our employees. Future specialists start their careers at SMS as junior staff in special apprentice workshops. Every year, more than 170 young people embark on vocational training at SMS, learning their skills from the bottom up.

Welding manufacturing image

Welding is too important to be left to chance
Components for metallurgical plants must withstand extreme static and dynamic stresses. That's why SMS uses a wide range of conventional and automated welding systems to ensure optimal welded joins. Our employees are experts in welding together different materials. You can rest assured that we meet all safety and quality assurance specifications.

Mechanical production image

Turning, drilling, milling, grinding, and shaping
All our manufacturing centers are equipped with latest-generation machine tools tailored to the specific requirements of heavy plant construction. Equally important, our equipment is CNC controlled. It's standard procedure for us to write the machining programs offline using a 3D-CAM system. Then we simulate the processes in advance so we can detect and correct errors even in extremely complex machining schedules. That ensures shorter lead times.

Gear production image

Specialists for heavy gears
Operation under high loads, at low oscillation, and around the clock - these are requirements our gears take in their stride. Yet that's only possible because we achieve precise dimensions, shaping, and positioning. Simultaneously, all our gear parts feature high surface quality, especially on the toothing. To meet the exacting demands of these special products, we set up a dedicated production area in Hilchenbach. It covers a floor-space of 4,000 m2 and includes complete machining centers for tooth milling and grinding, plus quality assurance and assembly zones. A standalone measuring machine inspects the gearing and can handle gearwheels weighing up to 40 t with diameters of as much as 5,500 mm.

Assembly and test fields image

Nothing is left to chance
Depending on the order, our teams pre-assemble or fully assemble products in several dedicated halls. Also included in the assembly workshop program are functional tests and trial runs performed on our own test rigs. Next there is our pipeline field where you benefit from precise CNC bending, welding, and laying of various tube and pipe materials. Furthermore, we carry out surface treatment of components, i.e. painting and preservation, as well as preparation for shipment.

Quality assurance
High production quality is our hallmark, with quality assurance an essential factor in achieving it. Here we apply our own standards, which go far beyond the usual norms. Our testing and inspection personnel is certified according to EN 473. This standard specifies principles for the qualification and certification of personnel carrying out non-destructive testing.


Manufacturing center Everywhere in the world to be close to you
Manufacturing Center Hilchenbach image

Manufacturing Center Hilchenbach

Siegerland is an old iron region. This is where the origins of the SMS group lie, with the foundation in 1871 of forging company Carl Eberhard Weiss. Who would have thought then that this would lead to the SMS group of global players? Today, the Hilchenbach production plant ranks among the most modern anywhere in the world.

Manufacturing Center Mönchengladbach

Manufacturing Center Mönchengladbach

It all started in 1872, when the Meer brothers founded an engineering factory in Mönchengladbach. Today, the location benefits more than ever from its traffic-favorable situation for heavy-load transports: There are two traffic hubs practically on the doorstep - in the north-south direction: freeway 61, and in the west- east direction: freeway 52. Also nearby is Krefeld, where heavy components are loa- ded onto barges on the river Rhine, taking them ultimately to customers worldwide.

Manufacturing Workshop Bhubaneswar

Manufacturing Workshop Bhubaneswar

The new SMS manufacturing and service workshop in Bhubaneswar, state of Odisha, equipped with machinery of the latest state of the art, is strategically located close to our customers. Most of them are within a range of some 300 kilometers. Especially conveniently located are the marine ports of Paradip (140 km) and Vizag (400 km), in close proximity of the plant. Via this gateway, our manufacturing shop will be able to also supply products to markets outside India.

Manufacturing Workshop Shanghai image

Manufacturing Workshop Shanghai

Deployed on site in Shanghai are German manufacturing specialists as well as qualified staff responsible for supplier management. There is a total of 300 employees working in Shanghai. Ranging over 26,000 m2 the site lies 5 km to the west of the river Huangpu. Each of the four assembly halls is 15 meters high, and together they offer 17,000 m2 of floor-space. Crucial to the smooth operations here are the options of reconditioning parts in the machining hall or quickly procuring new parts from the workshop's own parts store.

Contract Manufacturing

Individual solutions for your requirements

First and foremost, our modern workshops are dedicated to producing core products and components from the SMS group range. But it's also usual for us to take on external production orders, e.g. in the following fields:

  • Complex manufacturing of large parts
  • Small series up to a unit weight of 5 t
  • Mechanical drive components
  • Complete transmissions
  • Hydraulic systems and pipe systems
  • Assembly of components for machine tools and for general plant and machinery construction

We will be happy to answer any questions you may have, also during a personal meeting if you wish.

Consequently, SMS ensures top welding quality with employees who are experts in welding many different materials together. To carry out their work, they use welding machines for perfectly even seams. Our production shops hold the manufacturer's qualification for welding works according to certificate EN 1090-2 (comprehensive qualification certificate) as well as the extension according to DIN 15018. It's an approval which confirms that we meet all safety and quality assurance requirements for welding steel constructions.
