What is Resin Sand Casting? Resin sand is a type of quartz sand that is mixed with a resin material. The chemical reaction created by the resin helps to bind and stiffen the quartz sand to make solid, hard and strong molds. The resin sand can be used to create just a part of the mold, or the entire mold material.

An assessment of the most widely used molding sands technologies at present with organic binders (synthetic resins) from the no-bake group (furan no-bake and phenolic-ester no-bake) and their harmfulness to the environment and work conditions is presented in this paper.
A mixture of quartz sand and fluid synthetic resins with a hot-acting catalyst is used; The mixture is sprayed at 180°C-250°C onto the pattern or in the heated core box where it hardens by polymerization; Final hardening occurs subsequently; The castings have a weight ranging from 1 to 100 kg and a good surface finish. Disadvantages:
Explanation: The synthetic resins used in shell moulding are essentially thermosetting resins, which get hardened by heat. Phenol formaldehyde resins are mostly used, which combines with sand to form a proper mixture for shell moulding. The mixture formed has high strength and resistance to heat.
