About Extensio-Engineering
Extensio-Engineering is a one-person engineering office run by Sven Seifert (Bachelor of Engineering in Mechanical Engineering, over 10 years of professional experience), based in Oberkrämer, Brandenburg. The office specializes in the development and implementation of solutions in mechanical engineering, plant construction, structural steelwork and conveyor technology. Its services include CAD design with Autodesk Inventor from individual parts to complex assemblies, the creation of technical drawings and assembly drawings, the conversion of 2D drawings into 3D models, and reverse engineering with as-built measurement and optimization review of existing systems and components. In addition, Sven Seifert supports customers with the design of lifting attachments, crane systems and jig and fixture construction, as well as in the welding technology field. He optionally offers on-site support to cover customer capacity bottlenecks on time and to a high standard of quality.
