Main production division of ZSNP, a. s. in Žiar nad Hronom, division FINALCAST, is renowned Slovak foundry, with more than 40 years experience in the production of aluminum alloy castings. Among the advantages of this division belongs to the complexity of the customer service from acceptation of project through production of casting, up to mechanical machining to a condition that enables customer to immediate use in the casting assembly.

According to the division`s director Ing. Peter Gažúr, FINALCAST more than 90 % of its annual production is exported abroad, its service for many years is used by top-level global companies.

Unique in Slovakia with low pressure die casting method

Castings of division FINALCAST are applied in general engineering, energy and electronics manufacturing industry and agricultural machinery. Focuses on the production of aluminum alloy castings by casting into the gravity dies and low-pressure die casting method and finishing operations to provide increased mechanical, structural and surface properties of castings such as milling and turning on CNC machinery, shot-blasting medium CrNi40, Cr40, GRANOX40, tumbling – vibratory deburring/cleaning of castings, heat treatment. Additional surface finishes such as coopering, siliconing.

Castings, which have increased demand on dimensions and weight, as well as oil-proof, resp. water-proof technology are produced as low-pressure die casting, which enables production of aluminium alloys castings up to 1,2 m in diameter and weight over 35 kg. It is a unique technology, in Slovakia there is not other foundry with low-pressure die casting technology. Division FINALCAST produces by this technology wheels, electro-switch boxes, oil bath, switchgear bodies, compressor parts and other products.

The main advantage of gravity die casting technology is it`s flexibility enabling the production of aluminium castings of great complexity, including inner casting shaping using sand cores. The main production program of this technology is production of cylinder heads, pump bodies, components for cooling system in trucks and bodies of gasmeters.

Division Finalcast is equipped with latest technological equipment, as well as with devices which protect health of employees. Into this form it ZSNP, a. s. transformed after the privatization of this – one of the leading slovak manufacturer of aluminium by private equity group Penta, during subsequent restructuring. Since privatization in 2002 invested ZSNP, a. s. to modernize the division more than 9 million eur.

The investments mainly concerned the manufacturing process – Heat treatment line of Al castings, modern sand core machine Laempe 40, CNC machining centers, dispatch store. To improve the working environment of employees carried out the reconstruction of heating system, lighting and built a new soundproofed workstation for decoring of castings.

Annual production division has ranged in recent years around 1 100 tons of castings.
