The foundry plant UXA

The foundry plant UXA is one of the oldest and continuously operating foundry plants in Central Europe that has been in the operation since 1886. The annual capacity of the foundry exceeds 3,000 tons of ductile, grey and malleable cast iron. The foundry is equipped with the laboratories containing the metallographical microscope, the spectrometer with the certificate of qualification and the 3D measuring appliances.

Our own pattern-room enables the production of wooden and composite patterns. Cooperating with specialized pattern plants, we guarantee the production of accurate and complex patterns made of light alloys.

The foundry plant UXA holds the System of Quality Regulation Certificate EN ISO 9001:2015.

The production programme

We produce the grey cast irons, the ductile cast irons and special cast irons for the castings ranging from 0,1 kg up to 200 kg.

Chain and Chain Wheels

Pintle Chain

Pintle chain consists of open links made of malleable iron casting. The links are connected by steel pins that are placed in the eyes motionlessly while in the links, they are placed in a rotary way. The pintle chain is solid enough so it can be used in very demanding conditions.

Ewart´s Chain

It consists of closed links made of malleable iron castings. The links have a cylindrical pin on one side, whereas there is an open hooked sleeve on the opposite side. Within an appropriate angle, it is possible to hook the sleeve on the pin of the following link.
The chain is very flexible and strong, with links easy to be connected on whatever place, and therefore, the chain can be shortened or lengthened if necessary. The chain is resistant to humidity and it is stable even in warm conditions.

Chain Wheels

The chains and chain wheels are used for conveyor belts, reservoirs, small water power stations, agrarian machines, sewage water treatment plants, mills, brickfield etc.

ADI cast iron - material of the future

Isothermal Hard Ductile Iron (ADI) is an advanced material that is standardized worldwide by organizations such as ASTM, ISO and SAE.

ADI has grown over several decades in sectors such as heavy goods vehicles, rail transport, mining, agriculture and light vehicles.

ADI offers a combination of excellent mechanical properties, such as the high strength to weight ratio, which makes it worthwhile to replace steel forgings and weldments.

ADI offers good manufacturability and flexibility due to casting in the foundry. This allows designers to easily add or remove material where it is needed and thus easily achieve optimal solutions with minimizing costs, reducing the weight of the product, and eliminating unnecessary parts.
No need for welding or unnecessary assembly of multiple parts into one unit. Casting from ADI can have complex shapes.

ADI provides extraordinary good abrasion resistance. This extends the life of the workpiece.
Compared to steel, the ADI components are typically 20% less than steel and, moreover, weigh 10% less due to a lower material density.

"lighter than aluminum", ADI components are cheaper by 30% than aluminum, three times stronger than aluminum. Due to a density 2.5 times higher than Al, part of the ADI cast iron is lighter than aluminum.

Castings are much better than weldments in both appearance and mechanical properties.

ADI offers excellent workability in casting condition and conventional workability in hardened condition.

About company

1886-1948

Company founded by the Uxa´s family, focused on small-scale production of castings made of grey and malleable cast iron, the pintle and Ewart’s chains, mainly for textile industry.

1949-1992

Nationalization, the name changed to Juranov’s Plant, the transition from the traditional commercial production to the mass-production of the combat vehicles components for the armaments industry. ´

1991

UXA Ltd. founded, transformed into a commercial foundry plant oriented to the new markets of the European Union.

1999

Equipment renovation plus the introduction of the environmental-friendly technology, launch of the ductile cast iron production.

2008 - současnost

Entry of the strategic partner IUMEX S.p.A from Italy, extension of the production and shaping capacity of the castings.
