Mechanical Assembly Groups

The quality of individual precision engineering components is the cornerstone of high-quality assembly groups.

A large amount of expert knowledge and experience is required in the production of fine mechanical assembly groups, from the conception and manufacturing of individual precision engineering components to the production of complete assembly groups. Engelbert Sellmaier Feinwerktechnik GmbH offers you all services from the accompanying development of complex fine mechanical assembly groups to their manufacturing.

Fine mechanical systems: from individual precision engineering components to complete mechanical assembly groups

Individual precision engineering components are either created on the basis of precise customer specifications, are developed by us as needed, or are the product of cooperative development work. Our team of experienced employees and constant quality checks guarantee optimal results in the production process.
