Centrifugal castings

The interesting feature of centrifugal casting is the introduction of liquid/ molten metal into the rotating mold. Centrifugal force plays a major role in shaping and feeding of the casting. Centrifugal force produced owing to mold rotation is large as compared to the hydraulic forces. This force is used to distribute the liquid metal over the outer surface of the mold through hollow cylinders.

Salient features:

• 1 Meter of diameter for a 3 Meter long single piece cast.

In-house Infrastructure:

• 2 x vertical centrifugal machines
• 1 x horizontal centrifugal machine

Sand Castings

This is a versatile process for metal casting designs in which sand is mixed with a chemical binder/catalyst system and then molded around a pattern. In sand casting process the cooling rate is very slow that leads to a dendrite microstructure for non ferrous alloys.

Salient features:

• Single piece cast of 2500kgs.

Die Casting Products

This is a rapid, water-cooled permanent molding casting process that is quite limited to non-ferrous metals. The metal is melted, and then injected into a die cavity (permanent mould) under pressure. The pressure is generally obtained by compressed air or hydraulically. The pressure varies from 70- 5000kg/cm² and is maintained while the casting solidifies. It is cooled rapidly to form the part. The die-cast part is then taken through a number of finishing steps for a wide variety of end products.

Salient features:

• Single piece die casting of 20-25kgs

In house infrastructure:

• In-house die preparation

• Casting provides the greatest freedom of design in terms of shape, size and product quantity.
• Casting imparts uniform directional properties and better vibration damping capacity of the cast parts.
• The shapes that are difficult and uneconomical to obtain can be obtained by casting process.
• Casting can be done in one piece and therefore the need of metal joining can be avoided.
• Heavy and bulky parts (like those of power plants and mill housings) which are otherwise difficult to fabricate can be cast easily.
