    UNDERSTANDING METAL PROPERTIES

    Posted by Jason Bergman on 2020 Mar 3

    Metals are all around us, in the things we use to cook, drive, work, and live. When choosing a metal for a cast product or other specific application, it’s important to make sure that its properties will be suitable for the expected operating conditions.

    There’s a big difference between the kind of metal used in a skyscraper and the kind of metal used in a gate valve. Some metals are pure elements, like iron (Fe) and aluminum (Al), but most products are made from alloys, or mixtures of metals. Manufacturers must consider many variables before deciding which alloy to use for a particular product.

    What You Need to Know about Weld Repair for Steel Castings

    Posted by Mark Hollenbeck on 2020 Jan 28

    When done right, weld repaired castings are just as structurally and functionally sound as their non-welded counterparts. However, weld repair in steel castings is often misunderstood by casting customers. Some companies simply do not allow weld repair, and others place strict requirements on where weld repair can take place on a part. By better understanding the effects of weld repair on part appearance and functionality, casting customers can benefit from weld repair strategies that optimize cost, production time and part quality.

    What Is Design for Manufacturability?

    Posted by Rob Kriger on 2020 Jan 7

    Design for Manufacturability, or DFM, is an engineering practice that takes into account not just the way a product will look or function, but also how it will be produced. By applying DFM principles to new or existing products, manufacturers can improve product quality while optimizing cost and delivery time.

    According to Eagle Alloy CTO, Nic Tarzwell, "DFM is the measure of all the steps involved to produce the component cost effectively while ensuring it meets (or exceeds) expectations of form, fit and function." In order to optimize Design for Manufacturability, the customer and the supplier must work together to determine the best design and process for producing quality-finished products at the least cost.

    Tooling for Investment Casting

    Posted by AJ Menefee on 2019 Dec 18

    Tooling in metalcasting and CNC machining refers to reusable items that are specific to each job. In investment casting, tooling is considered to be wax-injection dies used to create wax patterns. If you're familiar with how investment casting works, you already know that these wax patterns form the basis of the investment casting process. Each part begins as a wax pattern, and the properties of wax – smooth surface, low melting temperature and excellent flow properties – that make highly complex investment castings possible.

    Understanding Casting Defects: When Is a Casting Returnable?

    Posted by Jeff Cook on 2019 Sep 24

    Metalcasting is a modern manufacturing industry, and cast products are utilized in 90% of durable goods, from lamp posts to space shuttles. Still, no casting is perfect. Even with recent innovations in simulation and process technology, nearly every cast product will contain some level of defect. A clear understanding of casting defects is vital for any casting customer, as it helps guide realistic expectations when working with a casting facility.

    While experienced casting facilities are skilled in finding a balance between cost and quality, purchasers should be closely involved in determining admissible levels of defects in deliverable products.

    What Precision Machine Shops Do: Grinding

    Posted by Nik Seyferth on 2019 Aug 26

    Grinding is a machining process using abrasive surfaces to remove material from metal workpieces. On the surface (pun intended) grinding may seem different than other machining processes, but it still works through chip formation and removal–just like sawing, milling, broaching and most other techniques. Grinding can produce surfaces conforming to rough or extremely close tolerances. Because of its versatility, grinding is used for simple gate removal in castings as well as advanced finishing processes like polishing and sharpening.
