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.

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.

Downstream processing such as heat treatment, testing, machining, segmenting, parting or splitting can all be performed in-house Guaranteed delivery programs OPEN DIE RINGS ROLLED RING ADVANTAGES At Scot Forge, we produce seamless rolled rings using an open die forging method or our ring rolling mill. Forged seamless rings are incredibly durable and reliable because they have inherent, circumferential grain structures and no weldments, eliminating weak points. Our seamless ring rolling mill is also a more cost-effective forging process than other methods because less starting stock is required to manufacture the ring. As a result, there is less material to machine away from the end product, another added benefit. When combined with a ring expander, ring rolling generates exceptionally round and durable ring products in any forgeable material. Seamless Ring Rolling Process The seamless rolled ring forging process starts with heating a pre-cut billet, then the malleable metal is placed on a hammer or press. The ring shape begins with a centerpiece "snapped" from the pre-form to produce a hollow center, similar to a donut, and moved to the ring mill. Once on the ring mill, the center of the part supported by a mandril and rollers apply pressure from different angles to gradually expand the ring. Rings made on a press are placed on a pin, supported by a saddle, then rotated as force is applied to expand the opening. Both techniques create circumferential grain flow creating the desired dimensions of the forged ring. This is our high-tonnage Wagner ring mill and ring stretcher in action! The Wagner allows us to produce: Straight rolled rings Contoured rolled rings The additional processing on our custom-engineered ring stretcher/sizer helps to minimize stock allowances, improve concentricity and cold-work aluminum rings.

Providing secondary services, helping distribute the electrical follow and supply reserve capacity, which will probably become a crucial element of the Smart Grid, facilitating 'demand response' resources. Giving utility planners and engineers flexible, reliable, and possibly less-risky alternatives to investments in conventional energy. Addressing growing electric service power quality and electric service reliability challenges, possibly by enabling utilities to provide differentiated electric service with higher quality and/or reliability. Forging for Energy Storage Including: Pumped Hydroelectric Energy Storage. A popular form of energy storage, pumped-storage hydroelectricity is typically designed to store excess power from the grid. Using the excess electricity to pump water up to a reservoir can be stored then released when demand rises. Similar to hydropower, once released, the water flows down through a turbine to generate electricity. The turbine/generator is similar to typical hydroelectric power plants that do not incorporate storage. Compressed Air Energy Storage. Compressed air energy storage (CAES) involves using excess energy to compress air at up to 1,000 pounds per square inch, creating a high-pressure system in a series of large underground chambers. This energy storage method is coupled with wind energy. When the wind speeds slow or power demand surges, the pressurized air energy, typically mixed with a bit of natural gas, is released to spin turbines turning generators to create electricity. Flywheel Energy Storage. Flywheel electric energy storage systems include a shaft connected to a cylinder that spins rapidly within a vacuum-sealed enclosure attaining rotational speeds up to 60,000 revolutions per minute. Some flywheels use magnetic bearings to levitate the cylinder, thus limiting friction-related losses and wear. Excess electricity is used to accelerate a flywheel (a type of rotor) through which kinetic rotational energy is stored. When the electricity is needed, the stored energy is converted via slowing the flywheel's rotational speed through a shaft that turns a generator. Thermal Energy Storage. Electricity can be used to produce thermal energy. According to the International Renewable Energy Agency, "coupling heating systems with thermal and seasonal storage offers important flexibility in demand in regions where winters are particularly harsh. For example, the Drake Landing Solar Community in Canada uses a long-term thermal energy storage system to store heat from solar collectors during summer for space heating during winter. In coupling the power and thermal sector, Siemens-Gamesa is testing a thermal energy storage system that uses wind power to produce heat stored in over 1,000 tons of rock. This system provides a thermal storage capacity of 130 megawatt-hours of electric energy at rated charging temperatures of 750°C. IRENA estimates that around 234-gigawatt hours of thermal energy storage are present, a crucial enabler of reliable, secure and flexible energy systems." Superconducting Magnetic Energy Storage. A superconducting magnetic energy storage system (SMES ) stores electricity as a magnetic field in an environment cooled below the temperature needed for superconductivity. As long as this temperature is maintained, energy can be stored indefinitely because the current will not degrade. Additional SMES components include power conditioning equipment and a cryogenically cooled refrigeration system. Methane. Researchers have developed a way to take the products of biomass gasification to produce methane, which is then be burned to power turbines. Methane essentially serves as an energy storage medium and can be stored or easily piped/shipped using the existing natural gas infrastructure.
