Rittal Software & Service at Siemens: Perfect production of customised enclosures

Most of the countless enclosures that leave the Siemens combination engineering (WKC) plant in Chemnitz each year are manufactured in small quantities. This means that super-efficient, meticulously organised planning and production processes are more important than ever. Only in this way is it possible to guarantee delivery accuracy and a high standard of quality, something which Siemens has been successfully achieving for the past 18 years with integrated system solutions from Rittal: beginning with the modular enclosure system TS 8, via cooling and power distribution components, through to innovative 3D development tools.

As suppliers of customised designs, Siemens WKC develops and produces high-quality switchgear primarily for the manufacturers of production machines, machine tools and transport systems. Despite manufacturing to order, the company's short delivery times and uncompromising quality standards set it apart from its competitors. To this end, however, throughput times must be minimised and all operations must dovetail seamlessly with one another. For this reason, Siemens WKC uses integrated system solutions from Rittal throughout every phase of development and production.

Even at the 3D modelling stage, Siemens WKC uses the Rittal components library RiCAD-3D, while enclosure configuration is carried out using Eplan Cabinet. The Rittal climate calculation tool Therm for determining cooling requirements is likewise integrated into the process. With the aid of computer-assisted engineering, the finished enclosure configuration can be simulated and tested in advance. This allows Siemens to save development costs, shorten delivery times, and ensure that all components are installed in line with the relevant standards.

Next up is the machining. The TS 8 enclosures are delivered just-in-time by the Rittal distribution and logistics centre in Gera, and can be pre-machined where necessary. Additionally, cable sets are pre-assembled with the routing module from Eplan, which translates into considerable time savings during assembly.

Dipl.-Ing. Hans-Peter Kasparick, Head of Process Engineering and Systems Engineering, Siemens WKC, explains: "One of the main reasons why we use Rittal is the availability of 3D data and the system consistency, from the TS 8 enclosures, to the opportunities for heat dissipation with cooling unit technology, through to software tools such as Rittal Therm."
