Aluminium Casting (GDC & SAND)

We manufacture mainly Valve bodies, Aircraft parts, Manifolds, Rings, Flanges, Covers, Housings Sand casting is a highly flexible form of casting that allows for the usage of recyclable and permanent patterns. Sand casting is a process used for handling high production volume processes. Sand moulds are crafted from diverse materials and the sand must be bonded together using synthetic compounds such as clay or water and the moulds have to rebuilt after every casting.

Filling the mould with molten material is a process that is gravity specific. The sand cores used for the formation of inner lining of hollow parts of the cast are formed from dry sand components. Moulds are prepared by pouring molten metal in the filling system.

Aluminium Sand Castings are used to make large parts and components. We have the expertise to handle the casting of sand moulds that are used to fabricate products and components of challenging complexities.

No Bake Aluminium Castings

No Bake is a casting process that uses chemical binders to bonded the castings sand. The sand is then transported to the mold fill station in preparation for filling of the mold. A mixer is then used to blend sand with the chemical binder and the catalyst. When the sand exits the mixer, the binder begins the hardening process. After the compaction process, a rollover process is used to remove the mold from the pattern box. The mould is then readied for handling the molten metal. After a shakeout process, the casting sand is taken away from the casting. Then various procedures follow including the finishing and the sand can be reclaimed by thermal means.

The chemical nature of the binders makes this a highly specialized process that has to be handled with considerable expertise and knowledge. At Sueeraa, we have developed our expertise in the process over the years and today are able to harness the potential of the process to create casts of the highest quality and to a great degree of accuracy.


  • Chemical binders are used to create high strength moulds.
  • When the temperature is brought to normal levels, the molds turn rigid.


  • It is adaptable to any quantity
  • It creates high strength moulds & improves dimensional repeatability
  • Requires low skill and labor requirements
  • Provides better dimensional control.


  • Ideal for high value and critical parts
  • Desired for Complicated Profiles

Gravity 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 is 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 Sueeraa, we have the expertise to undertake permanent mould castings of complex components of diverse application in various industries.
