Discover Apprentice & Internships Meet our people. Discover our spirit. View this video to learn about our unique culture. Everyone's An Owner Scot Forge is a 100% ESOP company where each employee, after meeting certain criteria, actually becomes an owner. Having a stake in the profitability of the company fosters a sense of responsibility to get every order correct, handle equipment properly and fully satisfy each customer. It also creates a progressive atmosphere where new and creative ideas for performing job functions are encouraged, as improvements in any area increase the value of the company and each person's share in it. An All-Salaried Workforce Scot Forge operates as an all-salaried workforce, meaning that all full-time employees (exempt and non-exempt) are afforded a 40-hour paycheck based on normal business and economic conditions. This policy has greatly contributed to a "team spirit of equality" among all employee-owners. A Culture Of Continuous Improvement Scot Forge is a real practitioner of the "continuous improvement process." There is an actual "CIP Leader" whose job is to train employee-owners in how to work on problem solving teams and to understand how valuable and important each of their contributions are to the success of the company. Earn While You Learn CNC Machine Operator Internship - Just one of the development opportunities offered at Scot Forge! Recognizing & Rewarding Service For every five years of service, employee-owners are publicly recognized at an awards dinner and, depending on the length of service, receive jeweled Highlander pins, pens, watches or cash. Additionally, in honor of ESOP founder and Chairman of the Board Peter Georgeson, our Peter I. Georgeson Awards recognize fellow workers who have gone above and beyond the call of duty for the past year. At the annual awards dinner, winners from six categories are recognized and publicly awarded a bronzed Scottish drum major statue and a bronze medallion to put on their hard hats or have framed. Consider, now, a seamless hollow-core Scot Forge forging that is forged at elevated temperatures with dynamic recrystallization (the immediate formation of stress-free grains upon deformation). The stresses introduced during forging to produce the cylindrical shape are immediately removed through the recrystallization of the crystal structure, resulting in an essentially stress-free forging. Consequently, a rolled and welded assembly possesses significantly higher residual stress than a forged seamless cylinder (hollow-core). Furthermore, no thermal stresses from welding are introduced during formation of the cylinder as a seamless forged hollow-core, unlike the rolled and welded plate method. To summarize, the Scot Forge seamless hollow-core forging is far more stable and possesses a higher degree of structural integrity (no welds!) than a rolled and welded cylinder assembly for an often lower overall cost. Proudly Plaid In 1977, the company's name was changed from Atlas Forgings to Scot Forge, and a Scottish highlander became part of the corporate logo. Not only did the new name reflect then-owner Pete Georgeson's cultural roots, it brought a friendlier, more personal image to mind. Along with the new name came a unique sales promotional tool—the wearing of tartan jackets, ties, kilts, scarves and other clothing by the employees. Today, Scot Forge employees are recognized in a crowd with their trademark plaids, and it has brought a certain pride to the employee-owners to be recognized as a member of the "Scot Forge family." Showing Our True Colors An in-house "store" carries casual clothing for men, women, children - and even babies - with the Scot Forge logo embroidered or silk-screened on virtually everything from sweatshirts to "kilt liner" shorts. In addition to the traditional tartan jackets and kilts worn for company functions, employee-owners and their families often display their company pride by wearing this casual Scot Forge logo-wear after working hours. Working Together, Playing Together Scot Forge builds camaraderie among its employee-owners with a variety of social events including annual picnics, golf outings, bowling competitions, canoe trips, and Christmas parties. Opportunities To Learn & Grow Tuition reimbursement and educational incentive programs allow employees the opportunity for advanced skills and knowledge through education and training. Scot Forge reimburses employee-owners classes taken and awards $250 for completing 40 hours of education in a calendar year. These programs give employee-owners incentive to improve oneself and put them in a better position for advancement. The programs promote the importance of education to the individual as well as the organization. Taken together, these and many other corporate programs and policies foster an environment where the employee-owners naturally want to work towards the common Scot Forge goal of providing total customer satisfaction. It is often said that people make the difference and that is especially so at Scot Forge. The combined creativity, enthusiasm, talent and team spirit shown by the employee-owners forms the basis for Scot Forge's success and leadership in the forging industry.

Scot Forge manufactures open die rings and rolled rings of various sizes and weights in both ferrous and non-ferrous materials. Open Die & Seamless Rolled Rings RING ROLLING IN ACTION Why Forged Rings? Typical problems associated with metal rings can frequently be traced to the metal-forming process. Cast rings are often plagued with substandard strength and integrity. Rolled and welded or cut rings out from plate are susceptible to fatigue and carry excess material and processing costs. The forging process produces rings with controlled grain flow , which gives strength and resistance to impact and fatigue not found in rings torch cut from plate or rolled and welded. In the cases below, these common problems were solved by switching to the forging process.

Open Die Ring Process Highlights To produce open die rings, material is first upset, then pierced to form an inside diameter. The ring is then drawn over a mandrel, if necessary, to achieve desired dimensions. Rolled Ring Process Highlights To produce a rolled ring, a preform is made by upsetting and piercing a hole on center. This preform is then placed on a ring mill and, through radial and axial pressure, is opened up to desired dimensions.

At Scot Forge, our Power Generation team is well-versed in the technical specifications of hydropower forging designs for large-scale projects. From wicket gates to turbine shaft components, we manufacture cutting-edge solutions to fix your most complex repairs. Our team works with one-off projects such as supplying forgings for maintenance on the Hoover Dam or repeat projects, which allows you to get ahead by scheduling your forgings to arrive when you need them, enhancing your supply chain. At Scot Forge, we look to be more than just a manufacturer; we want to be a partner in keeping your energy flowing. QUALITY ASSURANCE POWER GENERATION FORGINGS Forged Parts For Hydropower Generation Forged Shafts – Turbine shaft components, generator rotors, wicket gate shafts, guide bearings Forged Complex Shapes – Wicket gates, gate components, bolts, thrust runners Forged Hollows – Bearing sleeves, packing sleeves Forged Rings – Wear rings, break rings, collars Forged Discs – Circular discs for runner applications Hydropower Applications Different Types of Hydropower Facilities Conventional dams are not the only source of hydroelectric power generation; from pumped storage facilities to run-of-river sites, there are various ways to harness hydropower. With each application comes its own set of benefits and electrical output capabilities. Dams/Impoundment: Impoundment facilities, most often referred to as dams, generate energy by releasing water from an upper reservoir. The water flows through a turbine that activates and spins a generator, which produces electricity. These facilities are not solely dependent on the natural flow of water, and the larger the reservoir is, the more storage that can be provided for future energy generation. Because of this, impoundments can flexibly generate energy that meets both baseload and peak load energy demands. Pumped Storage: Pumped storage acts as a battery by moving water between two reservoirs. Water is pumped through penstocks from a lower reservoir to a higher one, which stores energy, and is then released back from the upper reservoir through turbines to generate electricity when there is demand. These facilities can compensate for demand-driven fluctuations and are an efficient form of bulk energy storage. Run-of-River/Diversion: Diversions, often called run-of-river facilities, channel water through a canal or penstock using river water’s natural flow. Because these facilities are reliant on the constraint of incoming water movement, the electrical output varies. Hydroelectric Turbines Whether you’re working with impulse or reaction turbines, both play a critical role in keeping your hydropower facility running efficiently. Impulse Pelton Turbine Pelton turbines are impulse-type turbines that use the pressure of water to move the turbine. Peltons are very efficient and rely on a drive wheel with buckets that catch water and transfer its energy to the generator. Our forgings for turbine components are used in applications such as the drive wheel, also called the runner, to provide quality and reliability where it matters most. So, whether it be an unforeseen emergency or a scheduled H-mod, you can count on us to follow through and deliver for all your hydropower needs. Reaction Kaplan Turbine The Kaplan turbine is one of the more widely used turbines in the hydropower energy industry. Because of the axial flow principle, Kaplan turbines work more efficiently at low water head and high flow rates than other turbine types. As a result, these turbines are ideal for well-ordered electricity production. However, while it is one of the most modern turbines, it can come with a hefty price tag to install and maintain because of the moving parts. This is why choosing a suitable material is critical for turbine longevity. Stainless steel grades help protect against cavitation and corrosion, providing your dam with quality forgings that will last and require fewer weld repairs. Francis Turbine Francis turbines, found in medium to large-scale hydropower facilities, mix reaction and impulse turbines. As the blades turn, they utilize both the reaction and flow of water to create power more effectively. Francis turbines are designed and assembled for a broad scope of heads and flows, making them the most commonly used hydroelectric turbine. Our technically trained team, from sales, engineering, production and testing, is experienced in developing forgings for Francis turbines, including shaft, drive wheel and guide bearing forgings.

Then, with the commercialization of electrical production in the 19th Century, new methods to produce electricity came about. These methods include steam engines, which became widely used to provide electricity, including coal-fueled boilers that provided power to operate boats and trains; nuclear energy was beginning to emerge with the development of nuclear fission. As a result, electricity became more readily available, and public buildings and businesses could have electricity. Around 1965, we were using Nuclear, hydropower and Oil & Gas to produce power in addition to traditional biomass, such as wood or charcoal. From 1990 to today, power generation continues to be an evolving industry with wind, solar and modern biofuels coming onto the scene. As new technology and energy sources power our world, we at Scot Forge are prepared to support them. From large spindles for wind turbines to step shafts for two-pole generator forgings.

Scot Forge provides a comprehensive list of all of the advantages of metal forging. Click here to learn more. Forging Structural Advantages Flexibility Of Forgings Give Your Components Improved Properties When you combine our mastery of forging with the knowledge of our technically trained sales team and degreed metallurgists, with the expertise of our forge engineers and heat treat and machining operators, you get a superior forging that will withstand the toughest demands Part integrity 1. Directional strength By mechanically deforming the heated metal under tightly controlled conditions, forging produces predictable and uniform grain size and flow characteristics. Forging stock is also typically preworked to refine the dendritic structure of the ingot and remove porosity. These qualities translate into superior metallurgical and mechanical qualities, and deliver increased directional toughness in the final part. 2. Structural strength Forging also provides a degree of structural integrity that is unmatched by other metalworking processes. Forging eliminates internal voids and gas pockets that can weaken metal parts. By dispersing segregation of alloys or nonmetallics, forging provides superior chemical uniformity. Predictable structural integrity reduces part inspection requirements, simplifies heat treating and machining, and ensures optimum part performance under field-load conditions. 3. Impact strength Parts can also be forged to meet virtually any stress, load or impact requirement. Proper orientation of grain flow assures maximum impact strength and fatigue resistance. The high-strength properties of the forging process can be used to reduce sectional thickness and overall weight without compromising final part integrity. Grain flow comparison Forged bar Grain flow is oriented to improve ductility, toughness, and increase fatigue resistance. Machined bar Uni-directional grain flow has been cut when changing contour, exposing grain ends. This renders the material more liable to fatigue and more sensitive to stress corrosion cracking. Cast bar Cast bars typically do not have a desired grain structure. Part flexibility 1. Variety of sizes Limited only to the largest ingot that can be cast, open die forged part weights can run from a single pound to over 400,000 pounds. In addition to commonly purchased open die parts, forgings are often specified for their soundness in place of rolled bars or castings, or for those parts that are too large to produce by any other metalworking method. 2. Variety of shapes Shape design is just as versatile, ranging from simple bar, shaft and ring configurations to specialized shapes. These include multiple O.D./I.D. hollows, single and double hubs that approach closed die configurations, and unique, custom shapes produced by combining forging with secondary processes such as torch cutting, sawing and machining. Shape designs are often limited only by the creative skills and imagination of the forging supplier. 3. Metallurgical spectrum Metallurgical properties can be greatly varied through alloy selection, part configuration, thermal mechanical working and post-forming processes. 4. Quantity and prototype options Virtually all open die and rolled ring forgings are custom-made one at a time, providing the option to purchase one, a dozen or hundreds of parts as needed. An added benefit is the ability to offer open die prototypes in single-piece or low-volume quantities. No better way exists to test initial closed die forging designs, because open die forging imparts similar grain flow orientation, deformation and other beneficial characteristics. In addition, the high costs and long lead times associated with closed die tooling and setups are eliminated.

We can supply step shafts and spindles precision-forged with allowance or rough-machined, which can also include drilling or boring. Continuous Grain Flow & Improved Microstructure - This means your part will have finer grain size, which will reduce the chance of voids and enhance strength leading to better fatigue resistance. Step Shaft & Rotor Shaft Process Highlights The process begins when an entire piece is forged to the major diameter and a fuller tool is used to mark the next step. Then we forge that next step to a smaller diameter or taper to create a contour, while maintaining directional grain flow, thereby giving the part greater strength and fatigue resistance. Depending on the configuration of your part, our Clinton, Wis. and Spring Grove, Ill. plants can forge custom flanged-end shafts with heads that are upset in a variety of shapes, including single, tapered or multiple-diameter.

00f0cbc1-e167-4af1-86d1-9cb1ccb16519 FORGINGS FOR INFRASTRUCTURE Reliability When It Matters Most The ASCE has called for “big and bold” relief for infrastructure post-COVID. Estimating it would cost $5.9 trillion over the next decade to bring roads, bridges and airports to a safe and sustainable level. This is about $2.6 trillion more than what government and the private sector already spend. The Bipartisan Infrastructure Deal (Infrastructure Investment and Jobs Act) alocated even more money to these areas for improvement while expanding the scope to internet access and renewable energy, to adress the climate crisis. As the world looks to improve infrastructure while preserving our environment, forgings are the perfect choice for many infrastructure applications. Forgings can withstand the demands of movable bridges, turbines, concrete and asphalt kilns, locks and dams, and other large civil engineering structures delivering high-structural strength and reliability. Our forgings, paired with our technically trained sales team, provide unmatched dedication as we work with you to design the components you need.
