Each stage of both processing and production processes is monitored and supervised by the qualified specialist personnel.

We continuously strive at improvement of the Integrated Management System, implemented in 2004. We do so in conformity with the requirements of the standards ISO 9001 and ISO 14001, allowing for production and sale of goods, characterised with repeatable and guaranteed quality. At the same time, we pursue a strategy of minimising negative impact of pursued activity on the environment. An important element of this system is Factory Production Control, owing to which we ensure its repeatability and obtaining product features in conformity with technical arrangements.
