Aluminium castings presently find application in a wide range of industrial applications. Other than being used by power generation equipment manufacturers, it is also used in the manufacturing processes of electrical and other associated industries. With present facilities of modern foundry, pattern shop & machine shop as well as arrangements for heat treatment & ultra-sonic tests also helps us to improve quality of castings everyday and deliver utmost satisfaction to our esteemed customers.
Our Expertise
As leading partners in the field of Aluminium Die Casting, Machined as well as Painted Assemblies, we successfully combine together latest technologies/platforms as well as rich experience gained in flawlessly handling the High Speed & High Precision Machining Centers. Our expertise also lies in offering turnkey production solutions that include but are not limited to tooling, machining, casting, pressure testing, mold alteration, plating, powder coating as well as assembly.
Casting Processes
We hold expertise in undertaking aluminium casting production using following processes
No-Bake
This is commonly referred to as air-set process that uses chemically bonded sand for producing medium to very large castings. Here, the best part-to-part dimensional accuracy can be successfully achieved on large complex castings. Other than this, large to medium size cores can are also be manufactured using this process.
- Most Efficient Sand Casting Technology Used
- Expertise in Handling Larger More Complex Castings
- Expertise in Creating High Strength Molds
Dry Sand
This molding process is used for intricate aluminium castings where refractory coating can also be applied to parting line surface for improving strength as well as heat-resistant characteristics.
Semi-Permanent Mold
This mold casting process allows castings in range from ounces to more than 100 lb. Further, various complex shapes can also be cast out using Aluminum alloys as well as these metal castings can also be cored.
Permanent Mold
These permanent molds make use of various Hall & Stahl hydraulic tilt pour machines. The use of this technique helps in reducing metal tumbling during pouring, thus resulting in superior metal quality.
Testings Done
In the field of Aluminium Castings, customer’s quality requirements are ever increasing. Our experience and expertise in such castings adds to our ability to offer competitive solutions that meet the defined finish and production time line. For achieving flawless finish quality, some of the tests that are conducted from our end include:
Simulation and Analysis Tests
Use of advanced simulation & testing software gives us advantage of testing all tools designed for gate design, cast fill, over flow design This process is achieved by conducting mould fill simulation as well as thermal analysis of designs at actual production parameters
This ensures good cast-ability as we are well aware of optimum machine parameters.
Other than this, the other quality testing done from our end include:
- Heat Treatment
- X-Ray Capabilities
- Ultra-Sonic testing
- Liquid Penetrant Testing
- Welding

Wax Injection
Imitation of the preferred investment casting is created by injection molding or for lesser volumes using speedy prototyping (SLA or SLS). These mock-ups are referred to as patterns.
Assembly of Wax Tree
Patterns are then fastened to a central wax stick, called a sprue, to form a casting. This is known as wax tree.
Ceramic Shell Building
The shell is made by submerging the wax tree meeting in liquid ceramic slurry and then into a bed of fluidized fine sands. Up to eight coatings are applied in this way depending on the shape and weight of the part.
Dewax
formerly the ceramic is dry; the wax is then liquefied out, making a negative impression of the meeting within the ceramic and sand shell. This process utilizes autoclaves to uphold shell reliability.
Conventional Casting
In the conventional lost wax casting procedure, the pre-heated shell (up to 1800 deg F) is poured with molten metal by gravity filling the metal into the ceramic shell. As the metal cools, gates, sprue, the parts, and filling cup become one solid casting. Shell temperature and dissolving temperature will differ depending on the alloy.
Knockout
once the metal is cooled and hard, the ceramic shell is wrecked off by tremor or water blasting.
Cut Off Of Parts
The parts are then cut away from the central sprue utilizing an elevated speed saw.
Finished Metal Investment Castings
Following minor finishing operations, or potential needed machining functions, the metal investment castings-identical to the innovative wax patterns--are prepared for shipment to the customer from our metal investment casting China foundry. We are able to offer finished cobalt alloy investment casting, steel investment casting, aluminum investment casting, stainless steel investment casting, nickel alloy investment casting and precision investment castings.
Wall Thickness
Please call for tolerance stipulation for wall thickness or any tolerances in common. As per the metal or alloy, least amount of wall thickness can vary from 0.04 inches to 0.08 inches.
- No flash or parting lines
- Almost any metal can be cast.
- Ready for use with little or no machining required.
- Very close tolerances and excellence surface finish can be obtained.
- Complex shapes which are complicated by any other technique are possible.
- Suit for producing complex shapes where other production processes are too expensive and time-consuming.
- Occasional minute flaws.
- The size of the casting is often limited.
- Time consuming as shell moulds cannot be reused.
- Expensive as many labor engaged in the preparation of the wax patterns & shell moulds.
