Stationary Die Casting
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 VAF Def-Aero Systems Private Limited, we have the expertise to undertake permanent mould castings of complex components of diverse application in various industries.

Tilt Die Casting
Some of the products made using Tilt Gravity Die casting process are Forks, tubes, cylinders and fins
Tilt gravity die casting process is mostly used in the production of parts with symetric and lengthy profiles
The pouring is done automatic in this process by filling the pouring basin manually and tilting the tool set untill the mold is filled. At VAF Def-Aero Systems Private Limited, we use tilting machines that can control the tilting speeds and die temperatures to get desired repeatability.
