Gravity Casting Services

Casting Services of Gravity / Permanent Mold Casting Gravity / Permanent Mold Casting is comprised of mold cavities fastened into metal die blocks and designed for repetitive use. Presently, molds are generally made of cast iron or steel, although copper, graphite and aluminum have been utilized.

The gravity permanent mold is the flow of metal into a lasting mold. The two methods that are used includes: static filling, where metal is introduced into the top of the mold via downsprues similar to sand casting; and tilt pouring, where metal is filled into a basin whilst the mold is in horizontal location and runs into the cavity as the mold is steadily tilted to a vertical position. Generally, Gravity molding is perfect owing to its more accurate attribute than shell molding. This is preferred almost exclusively to shell molding for light alloy components.

Benefits :

• Gravity casting is lucrative
• Produces superior quality components
• Offers process control
• Is greatest for creating small scale parts
• Does not need a large machine to inject the metal
• Needs much less start up cost than die casting
• Lends itself to more material types.

In gravity die casting molten aluminium is poured into a metallic tool. The casting temperature is about 750^oC. The tolerances and surface finish are good. The use of sand cores in gravity die casting enables casting of very complex components.

Gravity die casting method is competitive casting method when production quantity is relatively small or when heat treatment is needed to improve the mechanical properties. This casting method gives better tolerances and surface finish than sand casting. The tooling costs are somewhat higher than by sand casting.

Aluminum Die Casting produces highly repeatable, complex shapes and at very competitive prices. Aluminium is strong, light-weight, corrosion resistant, readily plateable and electrically conductive. That’s why aluminium die castings are preferred worldwide when performance, good looks and low cost are important. With cast-in steel components, extreme abrasion and wear resistance can be added to standard benefits of aluminium die casting. Rajshi uses cold chamber machine die casting for aluminium because of its high melting point. In cold chamber die casting, a precise amount of molten metal is fed into a “cold chamber” where hydraulic plunger the forces metal into the sealed die at high pressures.
