Quality assurance

Quality System

Department of Quality Control is independent from other production compartments. It ensures the fulfilment of customer requirements, supervision of production process and maintenance of quality management policy of our company.
Meeting of customer requirements is checked on every stage of production, from  inspection of a pattern and raw castings to a machined part.

QUALITY MANAGEMENT SYSTEM - is based on principles of ISO 9001 and supported by quality manual.

DOCUMENTATION - all control operations are registered and can be presented on customer request.

LABS AND TEST ROOMS

...we offer a complex solution

Our labs and test rooms provide quality control of castings manufacturing process and offer free capacity to carry out various tests for external customers.

The test spectrum is focused especially on analysis of metallic materials, mechanical tests, determination of structure, specification of inner and surface quality etc.

Furthermore, we offer consultancy concerning materials such as proposals of material to be used, foreign equivalents, thermal treatment and evaluation of damaged tools or parts. Thanks to a wide range of tests and services we offer a comprehensive service in this regard.

Quality system

The quality system of the labs and test rooms conforms to standards of EN ISO / IEC 17 025. The measuring equipment are related to national standards, periodically checked and calibrated.

The personell is certified according to EN 473, ISO 9712 and ISO 11484 for the non-destructive tests.

The labs take part also in certificate projects concerning the reference materials in OES (Optical Emission Spectrometry).

Test documentation

The records of performed tests are isssued in accordance of ČSN EN 10 204 in Czech and several foreign languages
