A wide range of products made of iron based materials is manufactured using innovative technology of actuation of sintering developed at the Plant. The products manufactured have enhanced plasticity, impact strength and machinability, they can be subjected to stamping and straining while doing assembly work. At the same time the cost of these products is lower than those sintered using the conventional technology.

Along with the conventional technologies to produce valve guide bushings and valve seat inserts made of sintered iron based materials, the Plant is in the possession of the latest technologies of obtaining dispersion-strengthened copper and iron based materials with their recrystallizing temperature of 800°C and accordingly the operational life is 3-4 times longer than that of the conventional ones.

We developed and produce materials obtained by sintering combined with hardening in the sintering furnace without any special hardeners (sinterhardening). With this process hard, heat-treated parts of high precision and clean surface are produced and they are ready to be assembled.

Another technology developed at our Plant allows us to produce powder large-size parts of complex shape and mass of over 1 kg having strength comparable to the one of compact steel. The parts are manufactured by pressing of the component elements with further sintering of composite construction combined with the process of infiltration and bonding. With this technology the quality of the products is enhanced and cost of production is reduced.

The products are compacted using conventional methods of single-press pressing on the domestic and foreign manufacture equipment, pressing followed by calibration after sintering. We also apply cold-working practice of sintered blanks, the process of step-by-step production, lubricated blends moulding, MIM-technology including. Automated engineering design of tooling, unified die sets, tooling adjustment outside the press are widely applied.

The total output of the Plant per month is over 1 m parts in the range of 200 item names being 0.15 – 350 grams of weight from simple to top complexity level and made of 15 material formulations.
