Introduction\u003Cbr>Dear Reader,\u003Cbr>Investment casting, or “Lost Wax” casting, as it’soften known, is one of the oldest forms of casting in existence. It’s also one of the most versatile and widely used casting methods today. Over thousands of years, the techniques of investment casting have changed very little, but the science behind the process–along with the equipment used–has allowed the industry to continually innovate.\u003Cbr>Today, investment casting is an excellent choice for a broad range of products. Nearly any alloy can be cast using this process, so the perfect balance of strength, weight and cost can always be found. Perhaps most importantly, investment casting allows for intricate shapes and complex inner cavities that cannot be achieved through other casting methods. Many parts that would otherwise have tobe fabricated or machined can be efficiently molded through investment casting.\u003Cbr>The purpose of this guide is to illustrate the history and current practice of investment casting, and to suggest a few of the possibilities afforded by the process .\u003Cbr>If you’re bringing a new product to market, or moving to a new manufacturing process, feel free to consult me with any questions you might have about investment casting, or metal casting in general.\u003Cbr>Sincerely,\u003Cbr>Debbie Pipoly\u003Cbr>President\u003Cbr>Eagle Precision Cast Parts Inc.\u003Cbr>231-788-3318\u003Cbr>[dpipoly@eaglealloy. com](dpipoly@eaglealloy. com) |\n| --- |\n| \u003Cbr>Investment Casting Process Guide\u003Cbr>[www.eagleprecisioncastparts.com](www.eagleprecisioncastparts.com 3)[ 3](www.eagleprecisioncastparts.com 3)\u003Cbr>Of course, there are times when investment casting is not the ideal process . Comparatively high labor costs and setup costs can make other casting processes a better fit in some cases . Furthermore, not every product needs the accurate dimensions, tight tolerances and smooth surface finish offered by investment casting.\u003Cbr>|\n\n\n| 2. Background & History\u003Cbr>5,000 Years in the Making, Investment Is Still One of Today’s Top Metal Casting Methods |  |  |  |\n| --- | --- | --- | --- |\n| Investment Casting is nearly as old as metal casting itself, with the earliest known examples dating back to 3,500 BC.1 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.\u003Cbr>Lost Wax Casting\u003Cbr>The earliest investment casting process involved shaping a pattern out of beeswax, a malleable material that could be rendered in high levels of detail. The beeswax pattern was then covered in clay, and the clay-wax combination was placed in a furnace, both to harden the clay and melt out the wax . Molten metal could then be poured into the clay shell, and allowed to harden into a detailed, smooth-surfaced casting. The process was known as “lost wax casting,” as it is still called in many regions.\u003Cbr>I","cbCaiqIVbMJjIUpY","https://ap.wps.com/l/cbCaiqIVbMJjIUpY","pdf",6431353,21,"English","# 1.
