Casting is a manufacturing process by which molten metal is poured into a mold, which contains a hollow cavity of the desired shape, and then allowed to solidify.

Below are listed some application areas of Casting



Purpose of Reverse engineering

•To bring existing physical geometry into 3D record•Extraction of 2D drawing.• It is used to analyse, for instance, how a product works, what it does•What components it consists of, estimate costs, and identifypotential patent infringement •Benchmarking of the given product.• It involves de-constructing and analysing products, but the objective is tofind opportunities for cost cutting



Advantages of using scanning for inspection

•Quickly capture all of the physical measurements of anyphysical object. •Save time in design work.•Ensure parts will fit together on the first try.•Capture engineering optimizations inherent inmanufactured parts. •Utilize modern manufacturing on parts that were originallymanufactured before CAD. •Compare "as-designed" model to "as-built" condition ofmanufactured parts



Inspection for Casting parts

• Obtaining accurate measurements of metal castings can be a challenge.

• 3D scanners are excellent tools to speed and simplify inspection and measurement or cast-metal parts.

• 3D scanners allow manufacturers to perform a complete inspection of complex-shaped castings.

• Unlike traditional methods that rely on the capture of a few pre-programmed points, a non-contact 3D scanner captures millions of data points and represents the true geometry of the component.



1. Sand Casting

Sand casting is a metal casting process characterized by using sand as the mold material. Sand castings generally have a rough surface, sometimes with surface impurities and surface variations. A machining finish allowance is made for correcting these kinds of imperfections

2. Permanent Mold Casting

This process is intermediate to Sand Casting and Die-Castings in efficiency, casting size and cost. Permanent mold castings are stronger than die and sand castings; less porous than die-castings consequently have better pressure tightness. This method is best used for quantities between 500 to 5000 units in a campaign. Sand casting process is used for smaller quantities and Die-castings is used for higher quantities.



3. Low Pressure Casting

The low-pressure casting process proves itself to be predestined for the conversion of exceptionally high quality demands. In low-pressure casting, the furnace is pressurized whereby the molten aluminium is brought into the casting die through the riser tube. The die is filled by slowly climbing, controlled, and above all, constant pressure. The laminar filling process avoids the formation of oxidation, the onset of cold currents and the danger of air inclusions.

4. Die Casting

Die casting is a metal casting process that is characterized by forcing molten metal under high pressure into a mold cavity. The mold cavity is created using two hardened tool steel dies which have been machined into shape and work similarly to an injection mold during the process. Most die castings are made from non-ferrous metals, specifically zinc, copper, aluminium, magnesium, lead, pewter and tin based alloys

5. Shell Mold Casting

Shell moulding is a process for producing simple or complex near net shape castings maintaining tight tolerances and a high degree of dimensional stability. Shell moulding is method for making high quality castings.

6.Investment Casting

Investment castings are typically selected because they can be produced with fine detail, excellent "as-cast" surface finish, shape into internal or external features, thin walls, and internal passageways to get to a near net shape. This often leads to significant customer cost savings in material, labour and machining.
