Sand casting is perhaps the oldest and most commonly used type of metal forming in the marketplace today. It is capable of forming both large and small parts and can be used for a number of different materials.
Global Casting Resources offers a wide range of sand castings. We offer both green sand castings and resin sand casings in both ferrous and non-ferrous materials.
Perhaps the most common green sand casting would be made from either grey iron or ductile iron. GCR can supply these castings from approximately one half pound up to approximately 5000 pounds and up to 700mm x 700mm x 700mm in size for the largest part. Molding methods range from floor hand molding, jolt squeezer lines and automatic molding lines. With this variety of molding methods we are able to accommodate the weight, size and quantity the customer requires.
Steel sand castings are available both as green sand castings and resin sand castings, and are available in plain carbon, low alloy and stainless steels. In the category of sand castings the smallest available part would be approximately 5 pounds while the largest would be approximately 30 tons for sand casting and 2 tons for resin sand casting. Steel castings smaller than the 5 pounds range would be made as a water glass casting (see Investment Castings ).
Non-ferrous sand castings are also available. The molding process used is green sand and we can accommodate requests for castings weighing from 1 pound to 12 pounds. The alloys that are available include copper base and aluminum base alloys.
First article layouts and spectrometer material certifications are provided with all first article samples. Specialized inspection reports including PPAP submittals can be done per customer request.
A variety of secondary operations can be performed on both types of sand castings. They include heat treatment, machining, plating, painting, polishing and buffing, assembly services and even custom packaging.
