Manufacturing technique of load-bearing elements cooler for a wide range of electronic devices (weighing from several grams to 50 kgs) from aluminum shapes of home and import manufacture is well-proven in mechanical production. Treatment technique (drilling, milling) with numeric control of type СМ-600 of glass fiber plastic and laminated insulation sheets up to 3 mm is mastered.
The enterprise is equipped with high production metal-working machinery of the leading foreign companies. For productivity increase during metal mechanical treatment a cutting tool of the BOMAR firm is used.
It provides: high-speed treatment, hard modes, high accuracy of cutting – up to 5 micron, up-to-date numeric control system, automation equipment for multiple-purpose plates, turn tables, vertical and horizontal jaw-vice, and nearly 90 types of tool changing.
label application by screen-printing technique on flat metal and non-metallic parts, including circuit plates;
production of directive and name plates on metal and plastic basecoats;
Technical image reproduction
delineation of circuit plates photo artwork, label master copies on photofilm and glass;
manufacture abroad of working nets for label application by screen-printing technique.
