1.      Mechanical processing’s by cutting

A.     The cutting workshop can carry out a various range of mechanical products (components), simple and complex, such as: straight shafts, shafts with excentric, sleeves, semicouplings, housings, flanges, splined shaft, screws, cylindrical wheels with straight and helical teeth, bevel geaz gear wheels with paloide toothing, common and spatial cams, gear racks, belt pulleys, chain wheels , worms, spiral wheels, nut bolt mechanisms, splined hubs, prismatic bodies, tools devices and checkers, stamping dies, dies .

End-uses : reducers , couplings, gears, fixed and demountable assemblies, gears, gear boxes, bearings.

Heat-treating workshop

2.      Metallic construction

- heat exchangers, filters, tanks, tools for agriculture, fittings from aluminum – all types- argon welding works, reconditioning, arming (valves, slide valves, admission valves), fitter’s shop works, filters
 
3.      Electrochemical coatings by chrome plating
-         Hard- chromium plating : Ø max = 400 mm ; l=1800 mm
   layer  thickness : (100-150) μm = (0,1-0,15)mm
 End-uses : shafts, spindles, bars, small pieces (sleeves, rolls)
 
4.      Rubberized pieces and products
-         are carried out from all rubber types
-         all sealing type (U,V)
-         rings “O”
-         rubberized rollers : Ø 600 mm, L=3000mm
-         extruding through nozzles until Ø50 mm
-         works which can be carried out on presses : L=900, l=900, H=1000 (mm)
