What Is Sand Casting?
Sand casting is basically the pouring of melted metal in a sand mold where it solidifies and forms a shape. The metal that is used in sand casting is iron, bronze, brass, and aluminum. The kind of sand that is used in a sand casting is silica sand.Here, the sand works as a mold which gives shape to whatever melted metal is poured in it. Roughly 60% of all metal castings are done by the help of sand casting. The special factories where sand casting has been performing for years is called as foundries.
Why Is Sand Casting Needed?
Send casting is needed because it is really affordable. This solution is also the most environmental friendly method for molding metals. It is comparatively a seat for mattered because of the safety and efficiency of sand used in this process. Sand casting has a huge need in industrial setup and can be used in various molding processes. Sand casting also has various applications in defense, water filtration, automobile, marine industry, medical fields, etc. They are also used in aerospace as well.
Pros of Sand Casting:
Mentioned below are some of the pros of sand casting:
- It is very flexible because its weight and size can vary according to any range from millimeters to tons. The only restriction that the casting face is due to the molten metal handling.
- Another vantage of sandblasting is that it has a wider material choice.
- Send casting also has a low cost overall, as it’s one of the cheapest method to make metal molding.
- It offers a huge complexity in various shaping of metals.
- Sand casting is available for complex because is where is the simpler forms of materials.
- Send castings also has a very short lead times.
- Send casting is also reliable for low quantities of material molding.
Cons of Sand Casting:
As we have mentioned the pros of the sand casting, it is also important to note that it also offers a few cons as well. They are mentally below:
- Send casting is it does not seem suitable for high tensile strength. It is because the porosity of the sand mold is quite limited.
- Sand molds do not cause a fixed pattern every time. The pattern and shape can change after being used repeatedly. Hence, they cannot be stored for a long time.
- Send casting also has a lower accuracy because it is not suitable for applications of tight tolerances.
- The finishing touch of the sand casting will not be as smooth as expected. The final look of the mold can be rough.
To conclude it, it is safe to say that you have learnt what sand casting is and what its applications is. There are various pros and cons of a sand casting which is also mentioned above. All in all, it is a very important process that has a huge demand in the world without having it cost too much.
