4. Introduction
 Also known as liquid-metal forging.
 Near net shape process - the initial production of the item is very close to the final (net)
shape, reducing the need for surface finishing.
 Combination of casting and forging.
 Squeeze casting is simple and economical, efficient in its use of raw material.
 The process generates the highest mechanical properties attainable in a cast product .

5. Squeeze casting process working
Squeeze casting consists of
entering liquid metal into a
preheated, lubricated die and
forging the metal while it
solidifies
The load is applied shortly after the
metal begins to freeze and is maintained
until the entire casting has solidified

6. Casting parameters
 Casting temperatures depend on the alloy and the part geometry. The starting point is
normally 6 to 55°C above the liquidus temperature.
 Tooling temperatures ranging from 190 to 315°C are normally used
 Pressure levels of 50 to 140 MPa are normally used
 Lubrication For aluminum, magnesium, and copper alloys, a good grade of colloidal graphite
spray lubricant has proved satisfactory when sprayed on the warm dies prior to casting

7. Case Study
 Effects Of Squeeze Casting Process Parameters On Density Of Lm20 Alloy
The experiment are carried out at different
squeeze casting condition to know the effect
of process parameters such as
squeeze pressure,Pressure duration,,Time
delay & Die temperature.
Experiments were conducted by varying one
parameter at a time and keeping the rest of
other process parameters constant.

10. Advantages
 Little or no machining required post casting process
 Low levels of porosity
 Good surface texture
 Fine micro-structures with higher strength components
 No waste material, 100% utilization

11. Disadvantages
 Costs are very high due to complex tooling
 No flexibility as tooling is dedicated to specific components
 Process needs to be accurately controlled which slows the cycle
time down and increases process costs.
 High costs mean high production volumes are necessary to
justify equipment investment

12. Applications of Squeeze Casting
 The squeeze casting has been commercially succeeded in manufacturing parts
include an Aluminium dome , ductile Iron mortar shell, and a Steel bevel gear.
 Aluminium automotive wheels and pistons, and gear blanks made of brass and
bronze.
 Compared with the HPDC, the squeeze casting process with high applied pressure
is a promising solution for thick magnesium castings
 Other parts that have been Squeeze cast include stainless steel blades, super
alloy discs,

13. Conclusion
 In conclusion, squeeze casting technology can greatly improve the
performance of aluminum alloys and other light alloys;
 promote the utilization of aluminum alloys instead of steel;
 reduce the weight of automobile, machinery equipment and military
equipment;
 promote energy conservation and environmental protection.
 Finally, squeeze casting technology can greatly lessen the impurity
restriction in raw material.MIT Pune
