<h1>Converting to Investment Casting: Is Your Part a Good Fit?</h1><h2>What makes your part a good fit for investment casting?</h2><p>When deciding on the best manufacturing process for a precision metal component, the design, cost, and timeframe allotted for production drive the conversation. If something isn't working as well as it should with your current process, you might start looking for alternatives.  </p><p>The manufacturing process chosen can significantly impact the final result. This is why many design engineers find the idea of converting to investment casting compelling.</p><p>Investment casting lets you cast almost any shape, in any alloy, with sophisticated and complex design features—all to exacting tolerances at a lower overall cost. Whether inefficiencies, added costs, or part variance plague your current process, converting to investment casting can add value to your project.</p><p>This blog will outline the three F’s of form, fit, and function that make a part a viable candidate for the process.</p><h2>Fit, form, and function</h2><p>When evaluating the suitability of an existing part for investment casting, these three areas are key:  </p><ul><li>Where will the part fit?</li><li>What form will it take?</li><li>How does it need to function to deliver maximum value?</li></ul><p>The answers to these questions determine whether investment casting is a good alternative to your current process.</p><h3>Fit</h3><p>Understanding how the part fits within the final product is important. For instance, is it currently part of an additional assembly process? This helps identify areas where you may gain greater value by simply recreating an existing part using investment casting.</p><h3>Form</h3><p>Consider whether the part has a simple or complex geometry. While investment casting can produce almost any level of geometric complexity, it's with highly complex components that the process offers the most significant return on investment. More traditional shapes like wedges or cope-and-drag style boxes are possible with investment casting, but it may not be as cost-effective as a simpler process like sand casting.</p><h3>Function</h3><p>Focus on the part's function. Is the component static or moving? Does it need to withstand impact and constant wear? Must it sit flush against another part in a way that can be pressure sealed? This gives critical information about the best-suited alloy. Being open to adjusting the alloy formulation used with a different process might lead to improved part performance with investment casting.</p>

<h1>Fit Form Function FAQs</h1><p>Part design is crucial to the success of any component. It's essential for the overall success of a project to remain on track in terms of timelines and deliverables. A supplier requesting a design for manufacturing review may seem like a potential hindrance, but an initial design review at the project's outset could save costs related to the fit, form, and function of the part, thanks to input from design experts. Below are some frequently asked questions about the investment casting process and how our team of highly trained engineers can enhance the design of parts.</p><h2>Is my part too heavy for investment casting?</h2><p>Just like any other manufacturing process, there are limitations with investment casting. In multiple steps throughout the investment casting process, the molds must meet certain weight requirements. Molds themselves have weight restrictions based on the type of alloy poured, maxing out at 100 to 120 pounds and meeting the industry weight standard. At other stages, molds are handled manually, or even automatically by Signicast’s state-of-the-art automation and robotics systems, requiring strict weight and safety restrictions.</p><h2>Does surface area cause limitations?</h2><p>There are three areas in which surface area has limitations—dip cells for the ceramic shell-building process, dewaxing where steam pressure is used to remove the wax from the shell, and then the burnout ovens.</p><h3>Dip</h3><p>The more surface area the part has, the more viscous slurry sticks, increasing the weight of the sprue and causing weight limitations for the robot.</p><h3>Dewax</h3><p>Now that there is a fully injected and dipped mold, there is the weight of the wax and the added weight of the ceramic shell. In this stage, there are personnel safety weight limitations to safely transport the molds in the plant.</p><h3>Burnout Oven</h3><p>The molds are fired to 1800℉, and once the temperature is reached, it's essential to ensure that the molds are still handled safely.&nbsp;</p><h2>How do I take full advantage of the investment casting process?</h2><p>As previously mentioned, almost every design will likely encounter a geometry, pour weight, or shell weight limitation during the initial mold design phase.</p><p>However, through a Design for Manufacturing (DFM) meeting, the&nbsp;Signicast engineering team collaborates to address potential limitations, increasing the value of the part from the outset. The part effectively "rents" space on a mold, so any changes or features added to the design are essentially free, as long as the footprint of the mold remains unchanged.</p><p>For instance, holes or bosses can be added to the design without increasing the overall footprint of the part. The number of pieces on the mold, as well as the piece part price, will stay the same. Small price implications might be added to the tool cost.</p><p>In a recent project, the Signicast Engineering team reduced a customer's piece part price from $23 to $18—a cost reduction of almost 30%. This price reduction wasn't due to the alloy cost, but rather a design change that allowed for more pieces per mold. The initial customer DFM session also leveraged the full benefits of the investment casting process by adding lettering, lot codes, part numbers, and logos on the parts at no additional cost.</p><h2>When should I consider alloy and heat treatment selection?</h2><p>Alloy selection and heat treatment are often considered early in the design process and not revisited later.</p><p>Some customers utilize cutting and grinding tools. A knife blade design, initially machined from solid 420 steel, was brought in for review. After discussing the part's function and conducting a DFM call, the in-house metallurgist suggested D2 tool steel. The result was a sevenfold increase in wear resistance, significantly extending the part's service life.</p><p>Considering heat treatment is also crucial. For parts requiring heavy machining, heat treatment and homogenization of the material before machining are recommended to minimize hard spots and broken tools. However, if extensive machining isn't necessary, heat treatment might be eliminated entirely.</p><h2>How can I eliminate machining and ultimately cut costs?</h2><p>By simply designing an investment casting with certain features, machining can be avoided, eliminating a significant cost associated with the part.</p><p>The engineering team frequently encounters prints with surface finish callouts. This often adds unnecessary costs. Many features machined on the casting are for size, position, or flatness. A surface finish callout is only necessary if it's for a sealing surface, O-ring groove, or a press fit. The DFM process can often help eliminate one or two machine passes, or even reduce the overall machining cycle time.</p><h2>How long does a DFM meeting take?</h2><p>The meeting duration typically ranges from 15 minutes to an hour, depending on the part's complexity and the potential areas for improvement identified by the engineering team. Within this timeframe, the team can conduct a comprehensive DFM call and conclude with actionable steps to enhance the quote or RFQ.</p>

<h1>Top 3 Design Tips for Investment Casting</h1><p>When designing for investment casting, all of our customers want the same thing, quality components that provide superior performance and durability. This requires sound mechanical design of the final component, reliable process controls, consideration of marketplace economic requirements, and clear communication among all parties. Most of our customers are not familiar with designing specifically for investment casting, so while the below tips are important to remember, we strongly urge you to involve our engineering team early during design to realize the benefits of our knowledge and design efficiencies.</p><p>Contact our team today to get the conversation started.</p><h3>1. Size &amp; Weight</h3><p>Part size and weight are the most critical factors in determining part cost because mold capacity is limited by both. The more pieces that can run on a mold, the lower the part cost. While almost any configuration can be investment cast, our team of engineers can help to optimize your part for the investment casting process by reducing part weight and optimizing design geometries. The key to the most cost-effective use of this process is to fully utilize its flexible capabilities and incorporate as many useful features into the cast piece as possible.</p><h3>2. Gating Design</h3><p>The number of gates you have has a direct influence on the cost of your project. The impact of the gate location on the component must be considered during the design phase, as it can be a careful balance between manufacturability, part function, dimensional control, and aesthetics.</p><p>When possible, a part should be designed so that a single gate can feed the part. This will generally yield more pieces per mold and reduce the pour weight per mold. Single gate feeding also enhances the dimensional stability of a given part by providing a directional solidification pattern.</p><h3>3. Component Castability</h3><p>Castability is very important to the investment casting process. Ideally, an investment cast component would be shaped like an icicle for directional solidification—you would pour from heavy to thin. If a design contains features that will raise scrap or rework rates (and piece price), a Signicast estimating engineer will recommend design modifications to help minimize costs.  </p><h3>Quality Investment Castings</h3><p>Early supplier involvement means Signicast’s in-house technical staff and CAD capabilities are available to help you to ensure that you receive the best quality component. The design tips above will only help to improve the way your component is investment cast, even if it was previously manufactured by another casting process. Unlike other casting processes, designing for investment casting has a unique set of efficiencies that can be utilized to create the best part for the best price possible<strong>.</strong></p>
