At Vel Castings, We harness advanced casting technology and data-driven insights to revolutionize how you source high-quality cast components, from prototypes to full-scale production.
Excellence in Every Casting
Melting
Melting is a crucial step in metal casting where solid metal is heated in a furnace until it reaches its melting point and becomes liquid. Various types of furnaces, such as induction or electric arc furnaces, are used depending on the metal type. Fluxes may be added to remove impurities. Once the metal is fully molten, it is superheated if needed, then poured into molds to create specific shapes and components.
Tapping
Tapping is the process of removing molten metal from a furnace once it has reached the desired temperature and composition. It involves opening a tap hole or tilting the furnace to allow the molten metal to flow into a ladle or directly into molds. Care is taken to avoid slag contamination. Tapping ensures a controlled and continuous flow of metal, which is essential for producing high-quality castings with minimal defects.
TUNDISH POURING
Tundish pouring is an intermediate step in metal casting where molten metal is transferred from a ladle to a tundish, a refractory-lined container. The tundish regulates the flow of metal into molds or casting machines, ensuring a steady, controlled pour. It also helps remove impurities and maintain temperature. This process improves casting quality by minimizing turbulence, reducing oxidation, and enabling continuous casting, especially in large-scale steel or non-ferrous metal production operations.
Moulding
Moulding is the process of creating a hollow cavity in the shape of the desired casting using sand, metal, or other refractory materials. The mould is prepared by compacting material around a pattern, which replicates the final object’s shape. Once the pattern is removed, the cavity is ready to receive molten metal. Proper moulding ensures accurate dimensions, surface finish, and structural integrity of the final casting.
VIBRO SHAKEOUT
Vibro shakeout is the process of separating solidified castings from the surrounding sand mould using controlled vibration. After cooling, the mould with the casting is placed on a vibrating platform or shakeout machine. The vibrations break the sand mould apart, allowing easy removal of the casting. This method is efficient, reduces manual labor, and minimizes damage to the casting. Recovered sand can often be recycled for future moulding operations.
SHOT BLASTING & FETTLING
Shot blasting and fettling are finishing processes in metal casting. Shot blasting involves propelling steel shots or abrasive materials at high speed to clean castings, removing sand, scale, and surface impurities. Fettling follows, where excess material like runners, risers, and flash are removed using tools like grinders or cutters. These steps improve surface finish, dimensional accuracy, and prepare the casting for machining, painting, or final use, ensuring it meets quality standards.
