Company history
PRB d.o.o. was founded in 1972 by Mr. Rudi Plestenjak. Until 1992, our main activity was the manufacture of metal products and tools for cutting and bending sheet metal. Washers and nuts made of Fe, Ms and Cu sheet metal with threads from M2 to M12 prevailed among the many types of products, and they were used in the production of switches, household appliances, water pumps, mechanical engineering… We also manufactured various metal component parts for electricity meters, metal hinges for the furniture industry, 16A cam switches, luggage ties for fastening loads, holders for thread cutting dies, spiral belt springs for Prvomajska milling machines ...
When the global trend of using metal products began to decline sharply, the production of filters and plastic injection moulding became the core activity of our company after 1992. At that time, we also started producing various plastic products. Injection-moulded filters and similar products of various shapes, sizes and fine meshes are our primary business.
We cooperate with the world’s largest technical producers in various production branches.
