Product category: Airless shot-blasting machines


“B” series shotblasting machines are designed for blasting products of mass production as well as those of minor series. Primarily, these machines are used for blasting grey cast iron, nodular cast iron, steel castings, and also aluminium castings, precise castings, forgings, and for deburring metal and non-metal products. Shotblasting machines of “B” series are produced in two basic variants, namely with a runner belt (R) and a steel belt (S).

Shotblasting machines of “B” type are called tumble belt because of the special shape of the belt that forms a loop in the shape of a tumble belt, whereto work pieces are loaded. Work pieces may be loaded into the machine manually or automatically with a skip in larger machines. During shotblasting, work pieces tumble continually in the loop formed by the belt under the jet of steel shot that is thrown by a turbine. After the blasting cycle is concluded, the belt turns in the opposite direction and work pieces are shot out of the machine.

About us

Company portrait

Company STEM d.o.o. was established in 1989 in Nova Gorica with the aim to produce and develop shotblasting machines with top quality solutions for the purposes of surface treatment, such as shotblasting, matting, shot peening, stress peening, roughening, and so on.

STEM d.o.o. is based in Nova Gorica, where we design and produce our shotblasting machines. In addition to having its head office and production in Nova Gorica, STEM has two more production plants; the facility in Tolmin, where smaller standard machines are produced, and the one in Čakovec (Croatia), where machines of largest dimensions are produced.

More 30% of our employees have post-secondary education. Hence, we are able to solve even the most demanding technical and technological procedures in the field of shotblasting.

As a result of the above mentioned, the sale of STEM products continues to grow, mostly on account of increased export. Namely, STEM company exports more than 95% of its entire production. Therefore, STEM’s products operate in nearly all European countries, and also outside Europe (Asia, the Middle East, etc.). Our most important references come from the most prestigious European companies, and also from the largest foundries in Russia.

Constant care is paid to the satisfaction of the customers already owning STEM’s shotblasting machines.
