Consider casting conversions for stronger, more sound and technically superior components and a better supply-chain solution. Advantages of Converting Casting to Forgings Why Forging Over Other Methods? Everyday economic and competitive threats, along with part failures, warranty issues and reputational impact drive manufacturing decision magkers to seek metalworking alternatives. SCOT FORGE EVALUATES CONVERSIONS ON A CASE-BY-CASE BASIS. We consider various factors, including the ability to redesign a product as well as the design requirements for the end-use application. Often, this requires engineers to challenge traditional methods and consider new technological advances. CASTING CONVERSIONS CAN FREQUENTLY LOWER TOTAL COSTS. Forgings usually target a lower total cost when compared to a casting or fabrication. When we evaluate cost factors, such as product life-cycle costs from procurement, lead time and rework, as well as costs of scrap, downtime and further quality issues and opportunity costs, the long-term benefits of forgings can far outweigh the short-term cost-savings of castings or fabrications. FORGING FOR COST REDUCTIONS QUALITY ASSURANCE Reducing manufacturing costs. Improving part performance. Minimizing material waste The Scot Forge customer value engineering team brings the knowledge of custom forging experts to work in your plant, helping you to achieve long-term cost reductions, enhanced part performance and improved lead times through: Near-net shape parts not previously available Component reduction - weldment elimination Optimizing your specifications and manufacturing practices Computer simulations to design parts to take advantage of forged properties Customizing alloy development and thermal treatments for your application Optimizing your specifications and manufacturing practices Consider Forgings Forging is a viable solution to your problem if you find yourself in any of these situations: Your component serves as a critical part of a product’s design The current design continually causes issues from your customer’s perspective You waste valuable time and materials on questionable castings Significant warranty issues Fast delivery and breakdown services You could be working on other projects versus re-machining parts (i.e. opportunity cost) The long lead times for the casting design result in downtime and lost revenue You spend considerable time searching for casting patterns or manufacturers You have design control over the end-use product Possible Problems With Castings Casting may be the best option for some applications, but when robustness in design is required many turn to forgings. From porosity to material inconsistencies, casting can cause more problems than solutions. But you can solve these problems by working with our employee-owners, we have advanced forging technology and the expertise to produce forgings for applications that require more complex shapes. Consider converting castings to forgings for stronger, more sound and technically superior components and a better supply-chain solution. The Best Casting is a Forging Having more than 125 years of metal forming experience, we can help you improve part performance and reduce costs.

Working together, our companies will create a lasting partnership—a partnership that is focused on getting you high-quality products, meeting your time constraints and helping your company be better prepared to go to market. Forging Conversion Profit Improvement: Construction equipment manufacturer A customer’s product had a long history of issues due to poor casting quality. Working with Scot Forge, they were able to transition the casting to a forging which removed all re-work and weld repair from their process and allowed them to provide a better component to their customer. This saved an average of seven (7) processing hours per piece. Defense contractor Scot Forge collaborated with a customer to convert a 22 piece fabrication into a two (2) piece forging design, saving over 500 hours in welding costs per unit. Mining equipment manufacturer Our customer’s casting supplier was not able to meet their production demand due to significant weld repair issues, resulting in a potential loss of a significant amount business. Scot Forge was able to provide a solution that met the customer’s demand and delivery requirements at a lower total cost than the casting, saving money and defending business. Forging Conversion Part Improvement: Product/application Rotor arm Material Alloy Steel Previous processing problems The previous process was a casting. The cast part, because of its lack of directional grain flow, did not have the required strength for the demanding application. Due to the lack of strength, part failures were occurring in the field, and the part had a short life span. Costly repairs and maintenance were necessary because of the frequent failures. Forging as the solution Today the part is forged as a one-piece forging. Forging provides a continuous grain flow which ensures high strength, integrity, and longevity. The improved strength has minimized part failures, as well as the need for repair and maintenance. Product/\application Centrifuge bowl Material Stainless Steel Previous processing problems The part was previously centrifugally cast. The customer required a stronger, more resilient centrifuge able to withstand heavy wear and tear, so production could be increased. To manufacture a stronger centrifuge as a centrifugal casting, the RPMs would have to be increased, and the higher loading would have exceeded the attainable properties of the material. The centrifugal casting tooling charge and process costs were expensive, and a stronger centrifuge required a more costly material. Forging as the solution Today the part is manufactured as a near net forging. Forging permitted the design change to a stronger centrifuge, while maintaining the customer's original alloy choice. The ability to handle increased service requirements due to a stronger centrifuge allowed the customer to increase production by 15% The forging cost for the improved centrifuge was 24% lower than the original centrifugal casting. Product/application Hub for a steel mill rolling application Material Alloy Steel Previous processing problems The part was originally a casting Casting failed to meet critical surface requirements, resulting in scrapped parts. At times, inclusions were not found until after extensive finish machining. Forging as the solution Today the part is produced by forging. The hub is now produced by forging and torch cutting. The part has higher strength and structural integrity due to forging's continuous grain flow. The use of cleaner, forging-quality material eliminated surface quality problems and rejections. Ensuring longevity Reducing cost Meeting surface requirements Make Scot Forge Your Forging Partner The knowledge and experience of our engineers, metallurgists and forging experts work in collaboration with your team, helping you to achieve long-term success. Rather than dismissing the idea as impractical or impossible, call on us to help enlighten you and your team of the technical and/or economic merits of any particular conversion project. We will devote as many resources as needed to provide a thorough review and subsequent proposed solution to your casting or fabrication problems. Related Literature Forging Raises The Bar on Magnesium Die Casting With the help of Scot Forge and Scot Forge’s creative engineering, Sloan Industries, Inc (Wood Dale, IL) discovered that using forging, rather than casting on magnesium die casting goosenecks yielded better machine performance and part quality. Unusual Shaped Forging Breaks Ground – Literally Scot Forge worked with Deca Industries to create a highly unusual three-spoke forging. The forging replaced a casting used in the mining industry. PET Scanner Forging successfully replaces casting PET scanner in medical application CTI Molecular Imaging (Knoxville, TN), in a joint effort with Scot Forge recently converting a cast component to a forging in the production of steel rings and hubs for its Eclipse Cyclotrons.

At the heart of the operation is our custom-designed, computer-controlled GFM single-stand planishing mill. Through a series of reversing passes, the planishing mill rolls the bar to a smooth surface in less than five minutes. While still hot, the bar moves down the GFM mill to the Braun abrasive saw station for trimming. A 16’ round can be cut in less than half a minute. To complete the process, the bar is end-stamped for traceability by an automated programmable marking system. The bar is then slowly rotated down an automatic uniform cooling bed to maintain straightness. Since the bars can be produced so efficiently in the planishing mill, delivery times are reduced. Unlike traditional hot-rolled bars, which can only be manufactured in large runs, forged Tartan Round Bars can be purchased in quantities as small as the product of one ingot.

Finish rolling (or planishing) begins as the forged bar goes through one of the four hyperbolic grooves of the custom-engineered GFM bar mill. The desired final dimension is reached after a series of bar rotations and reversing passes through the grooves, taking less than 3 minutes to complete. While still hot, bars are cut to size by a Braun abrasive saw. A 16" round can be cut in less than half a minute. Bars are end-stamped for traceability by an automated programmable marking system. Bars are slowly rotated down an automatic uniform cooling bed to maintain straightness. A 50,000 gallon quench tank and nine tip up furnaces have been custom-designed to efficiently handle any bar requirement. Process options include normalize, anneal, solution anneal, quench and temper, and stress relieve. A custom-built Hetran bar peeler provides fast, centerless machining to extremely smooth surfaces.

FORGING CONVENTIONAL ENERGY COMPONENTS Renewable Energy OEMs Are Forging The Future With Scot Forge At Scot Forge, we know how critical component reliability is to this sector of the energy industry. When companies extract, store, pipe or ship these fuels worldwide, the environment depends on critical components performing as expected when needed. We create precision-crafted, Forged Solutions, which our customers use when quality can’t be compromised. Many aspects of nonrenewable energy demand parts to withstand unforgiving environments with no room for error or failure, which is why OEMs turn to Scot Forge. TURBINES FORGE ENGINEERING Fossil fuels provide heat, light, electricity and many ingredients for things we use every day, such as plastics. They are relatively inexpensive to extract and, according to the Central Intelligence Agency, the world generates more than 66% of its electricity from fossil fuels and another 8% from nuclear energy. Energy Industry Forged Parts At Scot Forge, we can forge shapes for every portion of the conventional energy process. From mining and drilling to converting, shipping and storing conventional energy from natural resources, we forge generators, compressors, gearboxes, heat exchangers, blowers and more. Shafts: connecting rods for large diesel engines, industrial gas turbines and control rod drive mechanisms (CRDMs) Hollow Tubes: energy storage casings, reactor pressure vessels (RPVs), boiling water reactors (BWRS), nuclear waste storage containers and small modular reactors (SMR Discs & Blanks: nuclear grid blanks and industrial gas turbines, impellers, tube sheets and nozzles Complex Shapes: Nuclear waste storage container hatching Additional Shapes: Casings, spacers, centrifuge bowls, bearing blocks, shells and transition cones Rings: pump bearings and seals, Inconel end rings, crane gears Oil & Gas Extracting, such as deep-sea drill or fracking, and refining, such as petrochemical or oil refinement, require components to withstand high heat, pressure and corrosive environments during these processes, making forgings an ideal choice for the Oil & Gas industry power production. As crude oil is a fossil fuel that's used to make gasoline, diesel fuel, jet fuel, heating oil, lubricating oils and asphalt, our team understands that on-time delivery can be just as critical as part reliability. From ram and annular blowout preventers (bodies, doors/bonnets) to pinions and bull gears, our forgings exceed expectations. Natural Gas Mining natural gas is a process that looks the same as drilling for oil. Rock formations that contain natural gas deposits are drilled into until the gas deposit is located, with different places containing different types of natural gas: Conventional natural gas is in large cracks and spaces in rock formations Shale gas or unconventional natural gas is in tiny pores within rocks Associated natural gas is in crude oil deposits Freshly mined natural gas contains natural gas liquids (NGLs) like ethane, propane, butanes, pentanes and water vapor. This wet natural gas is then processed to remove the NGLs from the methane, which is then used for fuel. From drill heads for mining gas to hollow tubes for piping natural gas, our decades of experience, along with the time-tested relationships we have built with finishing shops, gives us the ability to help you reduce your material costs and allow us to support you and your timelines. Nuclear Power Nuclear power is the energy derived from a component of uranium called U-235. While uranium is not a fossil fuel because it is a common metal found in rocks, it's still considered a nonrenewable resource because U-235 is a rare uranium component. Our forgings support projects from nuclear reactor components and small modular reactors (SMRs) to radioactive waste storage and transport with unwavering reliability for the most critical applications. From new projects or maintenance to critical or time-sensitive situations, we understand the criticality of getting your parts to you on time with 100 percent compliance to the purchase order. Coal Even as the world moves toward renewable energy, coal is still one of the top energy-producing resources in the world, second to oil. On the other hand, in terms of electricity, coal generates more than 23 percent of the world's electricity mix, according to OurWorldData.org. There are four types of coal: Met Coal (Coke Coal) Anthracite coal with the highest heating value contains 86-97 percent carbon and is used in the metals industry. Bituminous coal is the most copious type found in the United States and contains 45-86 percent carbon, often used to generate energy and make iron and steel Thermal Coal Subbituminous coal with the lowest heat value contains 35-45 percent carbon. Lignite coal has the most moisture and lowest energy content; it contains 25-35 percent carbon and is used to generate electricity. With expertise in forging components for mining, which are found in the biggest trucks globally, draglines and electric rope shovels, along with competencies in concrete and asphalt industries, we offer a partnership that includes more than just manufacturing. We have the engineering skills to keep the mines running and the energy flowing.
