    Introduction to Greensand Casting

    Posted by Jim Smith, Jr. on 2019 Jan 22

    Greensand casting is a time-tested and highly versatile metalcasting process. Different foundries use different methods and materials, but greensand casting always involves creating molds by compacting moist, organically bonded sand around patterns. Whereas shell molding uses heat-bonded sand and no-bake casting uses chemically bonded sand to form molds, greensand casting is unique in that sand is bonded through naturally occurring compounds–in most cases, the bonding agent is clay.

    At Eagle Aluminum Cast Products, our two principle casting methods are greensand and permanent molding. The greensand process is very customizable and capable of manufacturing nearly any type of cast product. Here, we'll explore the processes, casting characteristics, benefits and challenges of the greensand casting process.

    Getting Started with Permanent Mold Casting

    Posted by Jim Smith, Jr. on 2018 Jun 27

    Permanent mold casting is a type of metal casting involving reusable molds. Whereas other casting methods, like sand casting and investment casting, use disposable molds, permanent molds last much longer and can be used to produce hundreds, or even thousands, of identical parts.

    Every project can be matched with the ideal casting method. For non-ferrous castings with medium-to-high volumes, permanent mold casting offers a long list of advantages.

    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.

    Aluminum Casting in Practice: A Case Study of Cast Aluminum Fan Blades

    Posted by Jim Smith, Jr. on 2018 Feb 21

     

     

    A major manufacturer of ventilation systems contacted Eagle Aluminum Cast Products, Inc. when demand was growing and they were ready to make a change.

    The customer had already been producing 48” fan blades for agricultural use through green sand casting, but they’d outgrown that method. Demand projections suggested that permanent mold casting would yield lower per-part costs, with the added benefit of greater consistency.

    Years later, EACP still produces fan blades for the customer through the process of permanent mold casting. Demand has increased even more, and product offerings have become more diverse. Read on to learn how EACP handles the design, production and delivery of this cast aluminum fan blade.
