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.
