    How Investment Casting Compares to Other Metalcasting Methods

    Posted by Deb Pipoly on 2018 May 8

    All metal casting processes have their own unique characteristics. When designing a new part for casting, the most appropriate process should be determined by a number of factors, including:

    • Tooling costs
    • Labor costs
    • Design characteristics
    • Desired appearance

    The goal of the manufacturer and the supplier should be to find the optimal balance that produces the lowest per-part cost at a given quantity, while meeting or exceeding all quality requirements.

    Here, we compare investment casting to three metal casting processes: shell mold casting, greensand casting and permanent mold casting.

    Aluminum Casting vs. Steel Casting: Choosing the Right Alloy for Your Cast products

    Posted by Jim Smith, Jr. on 2018 May 1

    In modern metalcasting, steel and aluminum are two contenders for the top material of choice. Thousands of manufacturers around the world rely on both metals to produce strong, light and corrosion-resistant metal parts and products.

    You'll find hundreds of different grades and alloys for both steel and aluminum, and each has its specific advantages and disadvantages. For this comparison, we'll focus on differences between aluminum and steel alloys in general, rather than zooming in on differences between specific alloys.

    Casting Aluminum: Comparison of Methods

    Posted by Jim Smith, Jr. on 2018 Mar 22

    Aluminum can be shaped through a wide variety of process, including:

    • Casting
    • Extrusion
    • Forging
    • Rolling

    For any type of metal, casting is arguably the most versatile of all of the forming processes, and results in the greatest variety of parts. In fact, the US Department of Energy estimates that over 90% of all manufactured goods contain metal cast products.

    The same casting techniques used for other metals can be applied to aluminum, but some of the most popular methods used with aluminum are permanent mold casting, greensand casting and die casting.

    How the Investment Casting Process works

    Posted by Deb Pipoly on 2018 Feb 15

    Investment casting, sometimes known as lost-wax casting, is a metal forming method known for its ability to produce parts with tight tolerances, complex inner cavities and accurate dimensions.

    As we discussed in our Introduction to Investment Casting post, the basic technique has existed for millennia. Over the years, innovations in equipment and methodology have kept pace with demand. Today, investment casting is one of the most popular forms of metal casting.

    Read on to learn more about the unique process of investment casting.

    Introduction to Investment Casting

    Posted by Deb Pipoly on 2018 Feb 1

    Investment casting is nearly as old as metalcasting itself, with the earliest known examples dating back to 3,500 BC. Before investment casting was invented, metal castings were created using open stone or ceramic molds. Investment casting allowed for much greater detail and smoother finish, vastly expanding the possibilities of metal casting.

    Today, investment casting is one of the most versatile methods of metal casting. The process, which is still similar to that used over 5,000 years ago, allows for tighter tolerances, more intricate shapes and smoother surface finishes than other metal casting methods.

    Foundry in a Box: Bringing Metalcasting to the Classroom

    Posted by AJ Menefee on 2017 Dec 4

     

    Ask a group of 5th graders what they want to be when they grow up, and you'll get a long list of answers: firefighter, detective, athlete, musician, astronaut. These (and other top kids' dream jobs) are certainly vital to our society, but as proud and forward-thinking manufacturers, we have to ask: Wouldn't you rather be a metal caster, or a machinist, or a Six Sigma coach?

    Maybe the answer is "yes," but the issue is that not many kids have been asked this question. That's where programs like Foundry in a Box come in. Dedicated professionals in the manufacturing industry visit schools and introduce students to the basics of metalcasting, and manufacturing careers, through hands-on projects. Programs like this not only expand students' horizons, but they're also vital to the future of manufacturing in the United States.

    How Shell Molding Compares to Other MetalCasting Methods

    Posted by Jeff Cook on 2017 Nov 27

    The shell mold process is unique and exhibits many advantages over other metal casting processes, but many people don’t fully understand its benefits.

    In this installment of the Introduction to Shell Molding blog series, we will compare and contrast the shell mold process with investment casting and greensand casting methods.  It is important to keep in mind that all processes have their own appropriate applications. 

    Based on your part's needs in terms of tolerances, production volume and surface finish, any one of these processes could be the ideal match.

    How to tell if casting is right for your products

    Posted by Deb Pipoly on 2017 Nov 20

    Our recent post on fabrication to casting conversion might have gotten your wheels turning. Now you're wondering, "Could my products benefit by making the switch to casting?"

    If you sell, use or otherwise produce fabricated parts, there's a good chance that you could produce them better, cheaper and faster through casting. To help you decide, we've prepared a brief Part Evaluation survey.
