NON-FERROUS METALS

The longtime tradition in casting and machine metal-working on home and foreign market, our firm takes notes since 1973. under the name TMPK -

Factory of metal product and constructions.

Since the year 2000 our firm works under the name IMPK - Industry of metal product and

constructions d.o.o., which is now in theprivate property. We have continued the

activity of metal altering in interconnected plant foundries, machine processings,

locksmitheies, producing and installing PVC carpentries.

Besides making the new equipment and parts, we do repairs andcorrections of different plant equipments, as well as the locksmith work,services of machine processing on delivered material and making spare parts for the

industry.

IMPK d.o.o. introduced a quality management system in accordance with the requirements of ISO 9001:2008 to achieve the highest possible quality level

of their services:
