Development and engineeringDevelopment and engineering

TAS-Schäfer GmbH has its own development and engineering department. Apart from extending our existing product range and improving our products and production methods, we also work on new concepts and solutions.
Many of our clients need customised or new products. One focus here is on the mutual development of specific solutions. In the process, we work closely with customers, suppliers and representatives.

In order to guarantee the high quality and functional reliability of our products, we make use of advanced processes:

  • Data exchange and provision of CAD data in 2D and 3D
  • Tolerance analysis and application calculation
  • 3D design and FEM analysis
  • Further development of our production methods
  • Optimisation of our assembly technique and testing procedures


Our products often have to be tested and certified by societies such as Germanischer Lloyd, Lloyds Register and others. For this, we draw up the specifications, calculations and other necessary documents.

A large proportion of the development work is devoted to the hydraulic shrink disc. Existing products are here incorporated into the development. We seek dialogue with our customers, so that their experience and suggestions for improvement can flow into our new product developments. This includes:

  • Testing and implementation of conversion and upgrade options
  • Repairs and adjustments
  • Conducting experiments
  • Development projects
