Sand casting:
In sand casting which is likewise known every bit sand molded casting, an object is produced past times sand mold. The procedure involves pouring of the molten metallic inward to the mold cavity. The molten metallic is therefore cooled to the room temperature. The metallic is solidified. After cooling, the metallic object is separated from the mold. Sand casting procedure has its advantages in addition to disadvantages. So tending should travel taken field making fragile products.
The half dozen main steps inward this procedure are -
- Pattern making in addition to placing it the sand mold.
- Making a proper gating organisation inward the mold.
- Removing the pattern.
- Pouring the molten metallic inward the mold cavity.
- Cooling the mold to the room temperature.
- Breaking the mold in addition to getting the casting.
Before making the mold the properties of the molding sand should travel checked. There are dissimilar types of molding sands. Each type of sand is used inward molding according to the shape materials in addition to application of the materials. Mainly Green or Natural in addition to Synthetic Sands are used.
Another of import percentage is the pattern. Different types of patterns are available . Before making patterns these affair should travel kept inward mind.
- Pattern material.
- Pattern Allowances
- Cost of making pattern.
Production steps inward sand castings:
Figure: Steps involved inward sand casting. This production sequence involves casting functioning in addition to designing in addition to mold making.
After removing the casting engineers should expect for the casting defects. If the defects are in that place therefore it should travel identified.
