Laboratory analyses

The technologically modern equipment of our test laboratories enables us to provide you with well-founded and reliable results that support you in the development and optimization of materials, products and processes, quality assurance and systematic failure and damage analysis.

The close interlocking between the material parameters determined by laboratory analysis and the software tools of Kunststofftechnik Paderborn lays the foundation for directly feasible simulation processes following the material analysis.

As a supplement to tests according to national and international standards, you benefit from customized solution options for individual questions. You will find an overview of our range of services in the detailed presentation.
