Thanks to a unique micro-fine molding sand and the exactness of our fully-automated Disamatic metalcasting process, VS Precision Castings are made to very tight tolerances. Our castings afford you the opportunity in many cases to significantly reduce or eliminate costly secondary machining operations by consistently producing dimensions up to ± 0.010". Our accurate core boxes and powder-like core sand enable the manufacture of cast-in threads and other extremely fine details.
