GSL testing processes: top quality guaranteed.

Sound verification of customer requirements


In order to ensure the top quality of our castings, we regularly carry out a large number of tests on our processes and the cast products.

Our qualified testing personnel are available to you with the corresponding test approvals and certificates for all tests. We are also happy to take over the acceptance of orders ready for delivery in cooperation with you or a commissioned acceptance company.

On request, we can provide you with test certificates in the form of certificates of compliance with the order 2.1, factory certificates 2.2 or acceptance test certificates 3.1 or 3.2 in accordance with EN 10204.
