Our Products
Also called as lost wax process, is a method to produce complex and fine shape under low costs. A mould of the final shape is casted in wax. Then it is coated with ceramic and dried. The wax is then removed from the ceramic in an autoclave by stream under high pressure.
Our Investment casting equipment portfolio includes Autoclave and Wax injection machine

We provide you solutions for both cold box and hot box core shooting technology, based on our experience gained from the installed core shooters. Wedeliver core shooters that can produce complex core shapes with short cycle time( usually less than a minute), completely automated till core ejection to reduce the cost of labour.Our Core Shooters produces cores ranging from 0.5 kg to heavy200 Kg cores.
Typical sand casting manufacturing process starts from making a sand mould which is negative of the part to be casted. To have hollow cavities in the cast part, cores must be used. The mould and core are fitted together and the molten metal is poured into it. The core is removed after the metal solidifies by vibration.
Based on our experience in the field for 18 years we offer you solutions for Moulding machines, Core shooters, Core sand mixers, Pneumatic conveyors for sand casting process.
Tiltable gravity die casting :
This process is used for casting low melting point material such as aluminium, copper and magnesium. By pouring the metal in tilted position of the die, the feed rate is reduced. This decreases turbulance and foaming of liquid metal. Tilting helps in smooth flow of metal in the die, thus oxidation is reduced considerably. Using sand cores complex geometries can be casted. The resulting cast has high surface finsih and close tolerance.

Surface blasting machines (sand / shot) are used to clean, peen, polish or improve surface texture. The components are blasted by shots/sand under pneumatic pressure by strategically located nozzles. They are done in enclosed or open space. Usual blasting mediums include metal beeds, sand particles, glass beeds, etc.
An Important factor to be considered to test the quality of aluminum cast in checking for the presence of bifilm. Bifilms are oxide layers formed during solidification on the surface of the melt. The presence of bifilm can be identified by porosity testing. When the metal is poured or stirred the bifilm layers formed at the top of the melt folds and drowns in the melt. Presence of bifilms in the melt can results in cracks after solidification. This results in low strength areas. During porosity testing, low-pressure environment is induced this causes the bifilms to expand because of positive pressure in the bifims. Once the melt solidifies, it can be cut to check the size of the pores formed. Bifilm index also indirectly measure hydrogen content in the cast. Porosity testing cannot independently identify hydrogen content as bubbles will not form without the presence of bifilms. It should be noted that porosity forms even without the presence of hydrogen, but the pore size can increase under high hydrogen concentration. Correlation between the properties of the aluminum with the bifilm index have been previously made by empirical tests. The general idea is as bifilm index increases toughness decreases. For a 40x55x15 mm cast a good rule of thumb is a bifilm index of 10mm represent a good quality of the cast, 10- 50mm represents adequate quality and anything above 50mm is considered low in quality.
Technical Specification:
Max Pressure = -0.8 bar/-25 in Hg
Motor = 0 .25 hp
Degassing:
The hoistable degassing unit is a foundry metal treatment system for removal of hydrogen from Aluminium alloys where it is placed directly on the crucible. The graphite rotor goes directly into the cruible and stirs the melt. Inert gas is blown in the lower end of the shaft to mix with the melt and remove the diffused hydrogen from it.
Features:
Degassing:
The Mobile Degassing is a foundry metal treatment system for removal of hydrogen from Aluminium alloys. The Degassing process uses an inert gas system of Nitrogen or Argon of Ultrahigh purity.

Aluminum is casted with metal dies. To produce high qualtiy Aluminiun casts, the hydrogen from the moulten metal has to be removed. Hydrogen dissolves when the metal comes in contact with water vapour in air. Hydrogen is removed in the moulten metal by purging with nitrogen gas. This reduces porosity in cast and improves mechanical properties of the casted alumium. Hydrogenis degassed using mobile degassing machines in ladle or directly in the furnace
Our Alumium casting equipment porfolio includes Nitrogen degassing, Gravity die casting and porosity tesing machines.
We manufacture vertical band saw for metal cutting used for alumium profiles and wood working process.
