What we do

From development and optimisation to machining and assembly, the Schweizer Group offers all steps leading to the aluminium and magnesium part ready for assembly. Our technology guarantees optimised and continuous quality.

Project management

The manufacturing process is only as good as the organization behind it. That’s why project management forms the core of our work. Every process step is covered, so scope for development can be fully exploited and improvements in each product creation phase can be made.


Designing means finding solutions. Our experience in simultaneous engineering offers the customer maximum flexibility for optimising the product and its manufacturing steps. The use of FEM calculations and full, solidification and distortion simulations ensure optimal and effective process development.


Development cooperation at an early stage requires our development team to be networked with those of our customers. This approach reduces correction loops. Those who collaborate with us at the first product creation stages go beyond usual optimisation and facilitate innovation.


Around 40 automated cold chamber die-casting machines with closing forces of up to 2,200 t are in use at five of our seven locations. Our proprietary, broad-based toolmaking facility and our maintenance teams ensure constant high quality and process reliability.


Our core business includes machining components ready for assembly. Machining operations occur at six of our seven locations. Cutting edge CNC machining centres and automated production lines ensure economic efficiency and consistent precision. Precision flatness, exact parallelisms, special surface properties and density are continuously monitoring.


The demands for technical cleanliness have grown, especially in the vehicle construction sector. The particle size for certain components must be smaller than 400 µm, and organic residual contamination less than 38 mN/m. In addition to the clean zones, which have been erected at all locations, the Plauen plant operates a clean room for meeting special requirements. This room achieves cleanliness to 200 µm.

Quality assurance

Quality assurance accompanies the entire process, from project and product realisation to series production through to spare part support. Quality planning methodically supports of the development department with tools such as APQP and PPAP, as well as with server-supported risk analyses (FMEA) and the production control plans derived from these analyses. In series production, quality control applies recognised problem-solving methods such as 8D, 5Why, MindMap and Ishikawa. From a technological perspective, 3D coordinate measuring technology, X-rays, computer tomography, measuring microscopes, surface measurement technology for roughness and surface tension, pressure differential tests, tension/compression tests, spectrum analyses, density measurements and crack testing, through to a fully-equipped residual contamination analysis laboratory, are all available for controlling product quality.
