Which is Better, Resin Sand or Coated Sand? What's the Difference？

Resin sand and coated sand are commonly used materials for casting metal workpieces, but the castings produced by them are different because of their different components. Coated sand is a kind of molding sand or core sand whose surface is covered with a layer of solid resin film before molding. Resin sand is self-hardening sand, cold hardening, hardening with curing agent; Coated sand is heat hardening, hardening by heating.

Why Ceramic Foundry Sand is the Ideal Molding Sand for the Lost Foam Casting?

Ceramic foundry sand used in lost foam process has obvious advantages and can control product quality more effectively and accurately. The emergence of ceramic foundry sand makes it possible to produce complex castings that could not be produced before, and makes the development of foundry industry a higher level. The appearance of ceramic foundry sand makes up the shortage of molding sand in the past and avoids the defects of castings.

Foundry Sand

The particle shape and composition of foundry sand affect the fluidity, compactness, permeability, strength and resistance to penetration of liquid metal of the sand, which is an important index of the quality of foundry sand.Foundry sand can be divided into two types according to mineral composition: silica sand and non-silica sand. There are generally three shapes of casting sand.
