CASTING: Iron, Steel, Aluminum, Copper, Bronze
TAKING YOUR IDEA FROM DESIGN TO DISTRIBUTION, ALL UNDER ONE ROOF
Iron & steel castings weighting between 0,5 and 5000 kg, single or serial production, depending on buyer’s requirements.
According to its use, we produce castings for railway, automotive, machine, building, mining, oil, chemical and food industry. Our assortment includes steel castings with special characteristics, such as wear resistant steel, steel resistant to high temperature and aggressive media, stainless steel, etc.
According to material quality we produce carbon, low-alloy and high-alloy steel.
We produce all kinds of wood, metal and plastic patterns.
We do premachining and final machining of the castings, depending on buyer’s requirements.
We do heat treatment of castings such as normalization, releasing, quenching and tampering in water, oil or air.
We do inspection on castings using control of chemical composition, NDT and test of mechanical properties.
Production capacity raised and reached a number of 12.600 castings in the particular year

Aluminium, copper and bronze casting
Sand Castings
We specialise in producing fully machined, tested and finished aluminium, yellow metal, brass, bronze and copper based sand castings to the defence, aviation, marine, medical, energy, automotive and safety-critical industries.
With over 40 years of experience and knowledge - and through a program of continual investment - we have the latest tools and skills to deliver your sand casting or gravity-die casting project and pride ourselves in our ability to find solutions to the most complex technical aluminium casting challenges.
Products would be provied and the range of the weight from 0.1kg to 300kg
Machining
We offer the full range of machining services, which includes turning, milling, grinding, drilling and inspection. Machining is carried out by computer numerical control (CNC). Specialist computers are programmed to guide the machining tools and shape the component accordingly.
Gravity Die Castings
Designed to work with our medium volume production casting projects, our gravity die castings production capability allows us to be extremely competitive on all gravity die castings projects. Our capacity for die casting is a nominal 40 kg while shell core and cold box core making facilities can be used in conjunction with this process.
Gravity die casting is used to manufacture casting parts from non-ferrous materials such as aluminium or low-temperature alloys. The process is used to create intricately shaped components for a wide range of industrial applications in the defence, medical and energy sectors. It involves pouring molten metal, under the force of gravity, into a pre-formed cast iron block which is fully machined to produce the die.
Heat Treatment for Sand and Gravity Die Castings
Heat treatment is used to improve the mechanical and physical properties
of aluminium castings, primarily to increase the tensile strength and reduce the ductility (stretch) of the metal.
Heat treatment is carried out in a highly controlled manner in specialised furnaces to ensure that the casting retains its original shape without cracking. The temperature is kept within very strict parameters to ensure
that the casting complies with the required specification.
