Usually made out of wood, metal or model board, patterns are used to create cavities in moulds. It is through pouring molten metal into these moulds that aluminium castings are created. Many factors have to be taken into consideration when designing a pattern to ensure the best and most cost-effective results.

Metal casting: After finishing the plaster casting pattern, you can pour molten metal into the mold to cast parts. Plaster Casting Application Plaster casting is usually regarded as low-cost substitute method of other casting methods. While it can only work with low non-ferrous and low melting point materials, such as copper, magnesium, and zinc.
Lift out the hot metal casting with tongs. Break apart the sand in the mold, and dump it back into the sand-storage container. Set the casting aside to cool, leaving in place the extrusions that the sprue, riser, and gates formed. When the casting is completely cool, cut off the gates with a hacksaw and file down the rough areas.
Matson Casting Investment casting patterns making process: Investment casting patterns often come in a single piece that resemble the final metal product closely—although runners might be built in for removal after casting. These pattern are cast from a material that can be melted or evaporated—especially wax patterns.
These types of patterns can be made from Wood, Aluminum, Plastic, Iron, or Steel. The investment in the pattern is the most expensive tooling component for molding in green sand. However, if internal cores are required, these pieces are made from a resin-bonded sand molded in a machined core-box.

The first step to making metal castings is creating a mold cavity. For this, you must use a pattern. You may use a CAD system to design the mold. After you've designed the pattern, you can pack material around it, forming the mold cavity. Next, you'll add a core, which is a solid material placed inside the mold cavity.
