Sand molding or sand casting as a technology has been around for millennia, and is selected as a preferred method to produce shaped parts from less than a pound, to very large parts. The process is very versatile and cost effective, even for low volume runs because of tooling cost. Nearly any part configuration that can be made in another material, can be reduced to a pattern and created in metal as a sand casting.
Two different core binder systems (no-bake, and oil) gives us many options in making a quality core needed to meet our diverse requests for different alloys, complex shapes and various sizes.
Air-set molding techniques are available for our customers. Flask sizes for no-bake range from 12" x 18" to as large as 72" x 72“. Larger sizes are available and can be discussed with our engineering department.
Three induction melt power supplies with six furnaces. Furnace sizes range from 400 lbs to 2800 lbs, giving SF&E flexibility in scheduling by weight and alloy. We can however, pour molds with a pour weight up to about 6000 lbs.
To meet the variable needs of our customers castings in size, shape and alloy, we have a diverse equipment list that includes three different cutoff options, four finish blasting medias (Aluminum oxide, Stainless steel wire, steel shot, bead blast), straightening presses and on-site NDT including RT, PT, MT, VT and UT.
