In 2018 the factory realized the project “Production of metal high-alloyed powders for weld-deposition, spraying and additive technologies”.
POLEMA’s equipment stock is unique for Russia: an atomizer, sieving and air classifier and a spheroidizing unit are set at the metal powders production site. The up-to-date equipment allowed us to expand the variety of manufactured powders and to enhance their quality.
You can see more information on production process and take a look at the list of powders for 3D printing produced by our company in our presentation.
