DUNES FOUNDRY PROCESS

Inhouse Pattern Makking

Pattern shop

Pattern making facilities includes 5 axis CNC router machine with CAD/CAM technology to produce pattern up to 3.0 meter in length & 1.0 meter height.
A team of highly skilled designers, pattern makers & pattern inspectors engaged in this activity ensures that the dimensions of the final cast product are strictly in line with the customers' requirements.
The in-house facility of pattern making helps in reducing the delivery lead time to the customer.


Automated Moulding

Moulding

The Quality of the casting is determined by high quality moulding process.
In order to optimize the moulding process a Continuous Sand Mixer unit with a capacity of 20 TPH from Omega Spartan, has been installed which is the best for today’s no-bake moulding process.
The moulding sector has a capability of preparing moulds for casting's weighing from 1kg to 2500 Kgs/piece.


Quality control

Quality control

The QC department has facilities with ARL Swiss made 25 Elements spectrometer for determining precise chemical composition of the metal and also Carbon Sulphur Determinator by wet analysis. Image Analyzer by Inverted Metallurgical Microscope DMI Premium series with digital photographic attachment are used to maintain precise alloy composition to meet ASTM standards. Mechanical testing like Tensile Testing, Hardness Testing and Ultrasonic detection for internal flaws are used to characterize the materials. Our Products undergo rigorous quality checks at every stage of production in order to ensure the physical & dimensional properties of each component.


Electric Induction Furnace 1.5 & 3 Ton Capacity

Melt Shop

Dunes Foundry has presently a melting capacity of 1.5 MT and 3.0 MT medium frequency Induction Melting Furnace for optimal melting and power efficiency and the capacity can be enhance to pour molten metal up to 4.5 MT by running both the crucibles at a time.


Heat Treatment Furnace 3 & 7 Ton Capacity

Heat Treatment

Dunes Foundry has a Shingo programmer controlled heating equipment which includes 7MT and 3MT Electric Bogie Hearth Heat Treatment Furnace. This helps the casting in achieving the desired mechanical properties such as Solution Annealing, Hardening and Tempering.


Finishing

Finishing

The adequate surface finish of the product is achieved by a Shot Blasting Y- Type Auto Machine -1000 kg/hr. Further the finishing is carried out with Swing Frame Grinder, Flexi Grinder, Pedestal Type Grinder and final touch by Die-Grinders.
