Sand Casting For Manufacture - Manufacturing Process
Dry sand molds are baked in an oven, (at 300F - 650F for 8-48 hours), prior to the sand casting operation, in order to dry the mold. This drying strengthens the mold, and hardens its internal surfaces. Dry sand molds are manufactured using organic binders rather than clay. Manufacturing Considerations And Properties Of Dry Sand Molds:

3. Packing of sand with ram The drag is then packed with more casting sand. It is a good idea to sieve all the sand being placed above the pattern and then ram it down firmly using a ramming tool. The tool has two ends, Cylindrical (used for general packing down of the sand) Pointed (Used for packing sand close up to the pattern).
