Casting After Rough Machining
This photo is of a casting for an oil refinery back east. This photo is after rough machining. Tolerances are very tight, and everything falls under 
ISO 9002 regulations 

Machine castings for foundries
After castings are poured to manufacture large steel parts for a variety of items, they are brought to us to rough machine the parts and prepare for final finish machining, assembly and delivery to the customer 

Production manufacturing of various items requiring close 
tolerance such as these lifting eyes
