What is your minimum order quantity?


Some metalcasting fa- cilities specialize in either


low-volume or high-volume produc- tion. Some off er both. Most customers want to reduce inventory and order quantity. Awarding a lower volume part to a higher volume metalcast- ing facility could result in longer lead times and higher quotes. Equipment designed to produce molds at high speeds for high-volume production are most effi cient when run- ning constantly without many pattern changes. A pattern set up and change to insert one of your low volume jobs results in lost molding time on the equipment and a cost to the metalcast- ing facility. T is cost may be passed on to you through setup fees. It’s best to select a casting facility that is designed for the volumes you have in mind.


This chart compares the various molding and casting processes with regard to tolerance and casting size. This data is provided as a guideline; the actual tolerances achieved can vary depending on each metalcasting facility’s capabilities.

Are you capable of producing complex castings?


If your casting is complicated, does the


metalcasting facility have experience with similar castings? Engineered cast-


ings are more than a lump of metal. Metalcasting is a shaping process on a specifi c metal that results in specifi c properties. T e process aff ords you the ability to let your imagination loose for shapes and internal features, but it is important to verify the metalcasting


Seemingly simple characteristics of a plant, such as good housekeeping and investments in improved work environment, are indicators of a healthy, profi table casting supplier.
