Greensand Casting Tolerances, Capabilities & Design Recommendations

Available Alloys

Currently EACP utilizes A356 and 319 aluminum alloy to produce all of our castings.  These two alloys are the most popular and provide options for your casting needs.  By reducing the number of different alloys poured, EACP also reduces contamination during changeovers as well as saves our customers money is set up charges associated with changing alloys.

Available Finishes

Greensand Casting Surfaces

We hold to the Aluminum Association standard of > 350 RMS finish.  We use the finest grain Olivine sand available to create the best finish possible on our green sand castings.

Additional Finishes and Coatings

Prior to application of coatings, EACP can prepare the casting surface using stainless steel shot.  This provides an even surface more accommodating to all types of coatings.  EACP has a wide selection of approved suppliers that can meet any of your coating needs including powder coat, paint and anodize.

Size & Weight Limitations

Our greensand process is capable of running larger, heavier castings with our largest flask size being 33″ X 80″.
