The Frog, Switch & Manufacturing Company

We are a world leader in the manufacture of manganese steel castings for the crushing and grinding industry.

For over half a century we have served a global base of OEMs, metallic mines, and aggregate plants.  Our castings are shipped all over the world. 

A long and fascinating history has led the company to where we are now – a major crusher parts supplier to the aggregate industry and to the growing global commodities markets of gold, copper, and iron ore.
