The history of the Private Commercial Production Enterprise (PCPE) “PROMSYSTEMS”, inextricably linked with the glass factory in the city of Kostopil, has been going on since the beginning of the 20th century.
In the middle of 1913, a Polish landowner created a glass guta, which produced bottles of various capacities and glass for kerosene lamps. After the Second World War, in 1946, the glass factory resumed its work, starting the production of the same range of products.
In 1962 the plant is subordinate to the Lviv Economic Council, the chief of the electronics industry. It was then that the construction of workshop No. 2 with two glass furnaces began, which produced glass insulators and flasks for electric lamps. 1972 in workshop No. 3 mechanical processing of glass and glass ceramics was mastered.
With the development of high-tech sectors of the economy, a need arose for new types of products and a workshop No. 4 was built for the production of glass substrates for integrated circuits. For this purpose, a workshop for the production of glass composite materials was purchased in the USA.
The peak of the plant's development reached in the 80s, when the company produces unique products for the radio-electronic industry, as well as consumer goods. The plant then employed about 3.3 thousand people.
With the collapse of the Soviet Union and changes in the defense strategy of independent Ukraine, the reduction and shutdown of most industries began. In 2003, a group of people, the former employees of the glass plant, it was decided to maintain production facilities and creation on their basis of an industrial enterprise "PROMSYSTEMS", under the production of the future: preform, glass powder, solder and sealing glass, frits, which use numerous plants in the production of:
-
radio-electronic industry;
-
semiconductor devices;
-
chemical current sources;
-
electrical connectors, sealed glands;
-
devices: nuclear energy, aircraft construction, household use;
-
mechanical engineering;
-
chemical components;
