Our casting network designs and distributes custom-made industrial-grade wear parts for the oil & gas, agriculture, mining & forestry, electrical, and facilities industries. Let Hawk Machine Works find a casting solution that is perfect for your next manufacturing project.
Types of Castings
There are various types of castings available. Where needed, Hawk will work with OEMs to help select the best casting solution for your manufacturing project.
Investment Casting (AKA: Lost-Wax Casting)
Hawk’s team of engineers and draftspeople can work with our manufacturing clients to perfect the investment casting design. Together with our network of casting experts, we create the pattern for the casting. We make sure the pattern precisely matches the design for the finished part. We ensure that there is sufficient allowance for thermal contraction (shrinking) when the casting cools.
Sand Casting (AKA: Sand Moulded Casting)
Sand castings are created using silicate (sand-based materials). Sand castings often use a bonding agent such as clay. The mixture is usually sprayed with water for strength and malleability. The sand/clay blend is contained in a mould box. The mould hollows are created by packing the sand around pieces called patterns, sculpting directly into the sand, or using 3D printing.
Plaster casting is similar to sand casting except for a mixture of gypsum, and a strengthening compound replaces the sand and clay blend. A plaster pattern is usually treated with a non-stick material to prevent it from sticking against a mould.
Die Casting (AKA: Metal Casting)
Die Casting moulds materials under high pressures. This moulding process is ideal for non-ferrous metals and alloys, such as zinc, tin, and aluminum. Die casting moulds are reusable.
