Stable Performance Steel Casting With Tight Tolerance
Sand Castings | Stainless Steel Sand Casting | MetalTek

Sand casting as a technology has been around for millennia and is selected as a preferred method to produce shaped parts that weigh less than a pound, to very large parts. The process is versatile and cost effective, even for low volume runs because of tooling cost. Nearly any part configuration that can be made using another casting process can be reduced to a pattern and created as a sand ...

Minimizing the cost of CNC parts (13 proven design tips ...

Tolerances should be defined sparingly and only when necessary. If a specific tolerance is not defined on the technical drawing, then the parts will be machined using the standard tolerance (± 0.125 mm or better), which is sufficient for most non-critical features. Tight tolerances are especially difficult to achieve on internal features.
