Process description:
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.
We have both green sand castings and resin sand casings in both ferrous and non-ferrous materials.
Perhaps the most common green sand castings would be made from either grey iron or ductile iron. We can supply these castings from
approximately 0.1Kg to approximately 15000 Kg and up to 5000mm x 2000mm x 1500mm 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 2Kg while the largest would be
approximately 20 tons for sand casting and 5 tons for resin sand casting. Steel castings smaller than the 2Kg range would be made
from 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 0.5 Kg to 100 Kg. 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
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.
