Green Sand Casting Kitchen Cast Iron Stove Grates / Gas Stove Cast Iron Burner Grates

As for the grates, the surface grinding and polishing is very important.All corners need to be grinded carefully. This is also a reason that many foundries could not make stove grates. Their workers are not familiar with the careful grinding works.

The metal patterns will be necessary, although the cost of metal patterns are higher than resin patterns, the wall thickness of grates is very thin, and have high requirements to surface smoothness and least surface flaw such as sand holes and air holes. Therefore, the metal patterns are necessary.

Making the grates need carefully workings during cast and cleaning processes. Of course, the good surface quality has to be kept by fine sands. The coarse sands can never make good grates.
