An unprecedented array of expertise

for a customised customer experience

At Spelsberg, we attach great importance to every part of our process chain, no matter how small, and use modern processes, the latest plant technology and highly qualified employees to ensure that everything is just right in the end. In order to leave nothing to chance, we pool all the expertise we need for the development and manufacture of our premium enclosures in-house. Whether development and design, toolmaking, certification or further processing steps such as the assembly of electrical and mechanical installation components and customized printing: only those who do everything themselves have all the parameters under control and can deliver absolutely high-quality, made-to-measure enclosures.

In recent years, we have greatly expanded the customizing area in order to be able to respond even faster and better to individual customer requirements. We believe that producing standard goods in large quantities is not an art.

That is why we use our chain of expertise not only to develop new and ever better products, but also to develop and implement a wide range of solutions for our customers.


We have established ourselves in the industry as an experienced advisor who solves tasks relating to water and dust-protected plastic and aluminum enclosures made to measure with a great deal of experience and passion. From consulting, development and production to testing and certification, we offer everything our customers need from a single source.

From sketch to product

We already have the VDE and UL regulations in mind at all stages of the process so that there are no more surprises when the finished product is tested. The fact that the tests accompanying development can be carried out in-house means that it is possible to carry out repeated tests and adjustments during the design phase until all properties comply with the standards. It couldn't be quicker or safer!

Prototyping through 3D product development

The basis of the parts produced by 3D printing is the digital design drawing, the data from which can be used directly by the printer. It works by gradually applying extremely thin layers of a light-curing plastic until the prototype is finished in the desired dimensions.

Proven variety of sizes and products

Empty enclosures from Spelsberg offer a wide variety of enclosure sizes and materials. If you cannot find the right product among the many variations of standard products, we will be happy to work with you to design a product tailored precisely to your needs. 
Thanks to the laboratory with its equipment, all empty enclosures are not only VDE-certified but also UL-certified, which is necessary for the international use of series products and special solutions.
