Comprehensive machinery

Our extraordinary manufacturing depth is our hallmark, a hallmark that guarantees you high-quality current-transmission components – made in Germany.

Your partner for in-depth quality

With our high-performance production facilities we carry out single item production as well as small and medium-sized series – and always with maximum efficiency. At MACK the batch size is not relevant on its own. We produce carbon brushes, sliding contacts or carbon brush holders in the quantity that you require for your unique current transmission systems.

We constantly invest in new technology as a matter of course. Together with the production of turned, milled, and stamped-bent parts, we also have an in-house plastic injection moulding facility. Thus we can not only mould and cut carbon bodies into shape, but also process most metal and plastic elements for a wide range of application situations. Everything from one source for you.

Step by step: a strip of brass needs several tool steps to become a finished stamped and bent part.

Made in house: the manufacture and maintenance of the tools required for production is completed in the company’s own tool workshop.

With the right turn: a threaded bolt is produced on one of our CNC turning machines.

Made by hand: the production of the clamps for our leg brush holders is also carried out in house.

In top shape: a finished plastic part is ejected in our plastic injection moulding workshop.

With great sensitivity: nearly all of our products are produced in a wide variety of versions – quite a lot of them are assembled completely at one single workplace.

Under high pressure: in the case of larger quantities carbon brushes and contact shoes are pressed into shape directly.

Fine finishing: a contact shoe blank is given its final shape on the NC milling machine.

Firm connection: a round copper conductor is incorporated into a multi-layer carbon brush.

“Manufacturing carbon brushes is a complex matter that requires specialist knowledge. Many of our colleagues in the manufacturing department have worked for MACK for many years, which ensures you too can benefit from a huge wealth of experience. However, we will not tell you everything about how we manufacture our high-quality brushes. That is something akin to the Coca-Cola recipe.”
