Gravity  Diecasting  in  Sikkim  leading provider of Gravity Die Casting Machine. It is fabricated using high-grade raw material. We also customized our products as per the given specifications of the clients. Our Gravity Die Casting Machines are highly appreciated by our clients.

When we use this technique the mold is not thrown away after every casting but since it is made of metal like cast iron or steel it is reusable. There are many ways of die casting, but high pressure die casting is most utilized. Low pressure die casting is used for about 20% of production. Rest of the production is being done by gravity die casting process.

A small amount of production is also being done with the help of newly discovered vacuum die casting and squeeze casting system.

Die casting moulds are these days permanent moulds and made of iron or steel. There are three different methods of die casting and these are high pressure die casting, low pressure die casting and gravity die casting.

High pressure die casting is the most used system in this melted aluminium is poured into a high pressure metal mold by hydraulic powered piston. The machinery used in this system is very costly. This system is only economical in very large scale production.

The low pressure die casting is best suited for production of auto wheels.

Gravity die casting is suitable for mass production and fully machined systems.

Some of the products made using Gravity Die casting process are Housings, Junction boxes, impellers, Valve bodies, Flanges, Manifolds, Actuator bodies, Compressor parts, Electrical fittings parts, Covers.

Permanent mould casting get their name from the fact that the process utilizes permanent metal moulds instead of temporary sand moulds for the casting process. Cast iron is the most commonly used mould materials as it offers great reliability during casting. The cores are made from other metals or sand. The cavity surfaces of the moulds are coated with fine layers of materials that have good heat-resistant properties such as clay or sodium silicate.

The moulds used in casting are pre-heated upto 200 ºC (392 ºF) before the molten metal is poured into the cast cavity. Casting has to be done with care in order to ensure that proper thermal balance in maintained throughout the casting process. This is done through a variety of ways including external cooling techniques using water or relevant radiation techniques.

Permanent mould casting, while not offering the same level of design flexibility and ease pattern usage as Aluminium Sand Castings, it has the advantage of offering relatively lower design and development costs as well as production costs. At VJP, we have the expertise to undertake permanent mould castings of complex components of diverse application in various industries.
