Resin Sand Molding Process. We also call this process as resin-bonded sand molding method. Because of the resin-bonded sand, the sand mold is harder than green sand molding. Additional burning of coated sand will make the sand mold solid. This creates a good surface and tight tolerance for the casting.

Sand contains more than 5% clay reduces not only permeability but also collapsibility and hence not suitable for core making. The commonly used core sand is a mixture of following items: (i) Core Sand: The sand may be green sand for smaller castings and mixture of fire clay, green sand and betonies for heavier casting.

A sand casting mold requires placing a duplicate of the object to be created into sand. The sand is packed tight around the object creating a mold. Once the sand hardens, metal or wax, is poured into the mold which creates an exact replica of the original object. There are a few different types of sand mixtures used. ...

12-03-2012· Sound casting products with metal penetration-free are designed such as whose maximum height of liquid head is under the allowable static pressure after filling. But, in the sand press casting case, it is confirmed that the penetration defect on the product surface is generated, even if the mould with a low static pressure is utilized.

Table 3.4 gives the compressive strength of the sand to be used for different casting materials. 4. Moisture Content Test: Moisture content may be determined by the loss of weight, after evaporation. A sample of tempered sand weighing 50 gm. is dried at 110 to 115°C, and then cooled to room temperature in desiccator and re- weighed.
