3D printing is a valuable tool for constructing prototypes when making cast metal parts. It speeds up the design process, allowing iteration and adjustment before going to the foundry. Read about how 3D printers are used in the cast metal industry.

What is hardness testing? The Brinell hardness test, Rockwell hardness test, and Leeb rebound hardness test show the properties of castings.
Learn how to select the right grade and class of ASTM A27 steel for your casting project. Each grade varies based on chemical composition, and type of heat treating needed to affect changes in mechanical properties. Find out the differences between testing steel for tensile strength vs. hardness.
How does a foundry create chambers inside the body of a metal casting? Cores are the answer: densely packed sand that stays solid until shakeout. Great design is necessary to float the cores through the center of the mold. Learn more about core-making in the foundry.
Molding sand is at the heart of the sand casting process. It must hold a shape well and capture the fine details of a casting, yet be permeable enough to allow gases to escape. Under the strain of having the molding pattern removed from it, or while it is filled, it cannot crumble or sink on itself. When it is turned upside down it must not lose its form: the parts of a mold have to stay true while clamped together.
Metal casting is the process of pouring molten metal into a shaped space so that it will cool and harden in that form. For many items, this process can be less expensive than machining the part out of a piece of solid metal. Even though the idea behind it seems singular and simple, there are many ways foundries cast objects. How they make a metal casting mold will depend on the metals used, the size of the run, and the shape, symmetry, and complexity of the casting.
A designer, entrepreneur, or inventor gets an idea and begins the process to bring it to life. At first the idea is made of sketches and plans, research and design, but the designer’s focus is toward creating a physical object. There is no replacement for holding a mockup or prototype and seeing a vision come to life. Prototyping allows the designer to have confidence in their idea, work out production flaws, and woo investors or clients.
Investment castings create complex, precision products. An expendable mold, often made of wax, offers superior finish and can create complicated forms.
9 essential elements of casting design, specifications, and communications needed to ensure your metal casting project is a success.
