Better Ways to Cast a Superior Quality Sandby Janki Patel Content Writer and SEO Analyst
Sand casting is the procedure to mold materials like metals into shape by use of hardened casts. The process involves mixing of sand with clay and water to get sand castings. These sand castings are then made into different molds as per requirement.
The steps involved in this process are:
- A cavity is formed within the sand after placing the pattern on it. when the cavity is formed, the pattern is removed.
- Now, molten metal at high pressure is filled in these cavities.
- The metal is left to be cooled. With cooling, the molten metal turns into a hardened object with the shape of the pattern.
- The sand cast is broken when the molten metal has cooled down.
- After taking out the mold, it can be given the desired finishing.
FEW EXAMPLES WHERE SAND CASTS ARE USED
- Doorknobs made of metals
- Jewelry making
- Trap pipes
- Metal sculptures
- It's versatile in nature
- Can be produced in practically any alloy
- Costs are reduced as the tools are not priced costly
