Advantages Of Open Die Forging Process What Is Open Die Forging? Open die forging involves the shaping of heated metal parts between a top die attached to a ram and a bottom die attached to a hammer, anvil or bolster. Metal parts are worked at their appropriate temperatures, ranging from 500°F to 2400°F, and gradually shaped into the desired configuration through the skillful hammering or pressing of the workpiece. Difference between open die forging and closed die forging While impression or closed die forging confines the metal in dies, open die forging is distinguished by the fact that the metal is never completely confined or restrained in the dies. Most open die forgings are produced on flat dies. However, round swaging dies, V-dies, mandrels, pins and loose tools are also used depending on the desired part configuration and its size. Although the open die forging process is often associated with larger, simpler-shaped parts such as bars, blanks, rings, hollows or spindles, in fact it can be considered the ultimate option in "custom-designed" metal components. High-strength, long-life parts optimized in terms of both mechanical properties and structural integrity are today produced in sizes that range from a few pounds to hundreds of tons in weight. In addition, advanced forge shops now offer shapes that were never before thought capable of being produced by the open die forging process. spindle-shaped part open die forging process: 1. Starting stock cut to size by weight is first rounded, then upset to achieve structural integrity and directional grain flow. 2. A "fuller" tool marks the starting "step" locations on the fully rounded workpiece. 3. Forging or "drawing" down the first step to size. The second step is drawn down to size. 4. Note how the part elongates with each process step as the material is being displaced. 5. "Planishing" the rough forging for a smoother surface finish and to keep stock allowance to a minimum.

The bar rolling and planishing process is used to produce Tartan Bars®, a unique bar product offered only by Scot Forge. Click here to learn more! Bar rolling & planishing What Is Bar Rolling & Planishing? At Scot Forge, we can produce anything from a single bar to a full heat with our bar rolling or planishing expertise. Planishing and bar rolling are techniques we use to significantly reduce energy consumption and improved material properties. The metal's tendency to resist deformation is low when it is hot, which reduces energy consumption. Hot rolling can improve the performance of metals and alloys by refining the microstructures in the metal. Coarse grains in the metal are broken, cracks are healed, casting defects are reduced or eliminated. Finish rolling (or planishing) begins as the forged bar goes through one of the four hyperbolic grooves of our custom-engineered GFM bar mill. The desired final dimension is reached after a series of bar rotations and reversing passes through the grooves. Using this process, we can offer Tartan Bars from 6" to 16". Larger precision forged bars up to 63" diameter can be manufactured on our open die presses. Take a look at the bar rolling and planishing process in action! We use these methods to produce Tartan Bars®, a unique bar product offered only by Scot Forge. These bars are produced by combining a preliminary forging process, consolidating the center with a planishing operation, which provides a smooth rolled surface.

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.

4b5ede0a-1d0d-4925-a988-02229f8f9ec1 PNUEMATIC FORGING HAMMERS What Is A Pneumatic Forging Hammer? With more than 10,000 tools the hammers at Scot Forge can create small to medium size forgings quickly and cost-effectively, saving you time and money on manufacturing tools to forge your components. Pneumatic hammers consist of a frame, an anvil and a reciprocating ram holding a hammerhead or die. The billet is placed on the lower anvil or die, and the head or upper die strikes the workpiece until the desired shape is achieved. Tools are used to create shaped pieces like hubs or rings. A typical pneumatic hammer works by storing potential energy in an arrangement of mechanical linkages and springs, in compressed air, or steam, which it will use to manipulate a billet. The stored potential energy provides a more forceful stroke than merely allowing the weight to fall. Take a look at our hammers in action! In Franklin Park, IL, we forge both ferrous and non-ferrous forgings are produced on six open die pneumatic forging hammers in part weights from 1 lb. to 3,000 lbs. and in quantities as low as a single piece. Lower Costs & Lead Times Torch cutting to near-net shape saves material and machining costs, and by combining torch cutting with the forging operation, you also get the integrity of forging without the cost and long lead time often associated with other metal working processes. Torch Process Highlights Our torches can cut through carbon and alloy forgings with pre and post-heating operations that minimize thermal shock and protect forging integrity.

FORGINGS FOR MARINE PROPULSION Marine Propulsion Forgings For: Superyachts, Cruise Ships, Submarines, Naval Ships & Patrol Vessels At Scot Forge, we provide marine shaft forgings, propeller shaft forgings and forgings for many other propulsion shaft parts to meet these standards. We even offer the certifications that keep your project propelled toward success - including ABS*, Lloyd's Register and DNV-GL . With the long trips and large loads that seafaring vessels undergo, there is an increased need for marine shafts to produce more power and even do so with reduced noise. This demand has led to the design and manufacturing of more efficient propulsion shafts. Our team is well versed in acting as an extension of your team to review blueprints and materials to ensure flow-down requirements are met. *Scot Forge pricing includes all ABS surveys and certification fees MARINE & ABS FORGING CONSULTATIONS SHIPBUILDING Marine Shaft Forgings Marine Propulsion Shafts/Bars A propulsion shaft is a part of a system that generates thrust for a boat, ship or barge, allowing them to move through the water, also known as marine propulsion. Marine propulsion uses a thrust block, located at the forward end of the main shaft, with the shaft line that incorporates all the components to move the vessel. These components include the propulsion shaft, which is used in conjunction with the tail shaft, intermediate shaft, thrust shaft, flange coupling, gearbox, marine engine components, propeller shaft, propeller and bearings that hold the shaft's alignment. Shafts For Marine Applications: Propeller, tail and drive shafts Rudder stock, upper vertical, lower vertical shafts and pintle pins Line, intermediate, main and stub shafts Controllable and variable pitch shafts Flanged torque shafts Input shafts Marine shafts are subjected to many loading types during use, including torque, bending, axle thrust and transverse load. In addition to load stress, weather and sea conditions create corrosion and wear and tear, reducing the propulsion shaft's lifetime. All of these reasons are why the requirements are so severe for these types of forgings; many "simple" parts play a critical role in not only performance but also crew safety, which is why finding a reliable partner for manufacturing these critical parts is essential. Forging Experience & Capability: Ship, Submarine & Boat Shaft Forgings At Scot Forge, we know working to regulations for marine applications costs time and money.

FIA MAGAZINE | FEBRUARY 2021 Got Constraints? Theory of Constraints Applied to Scot Forge Supply Chain In many cases, the ability of a supply chain to perform reliably over time is a key contributor to the success of a business. Very few supply chains are identical with different variables that seldom remain constant over a long period of time. Occasionally it can seem like an impossible task to maintain synchronization of all those variables in the supply chain, particularly when things typically go wrong at the worst possible time (Murphy's Law). Inevitably, the worst time typically occurs when something changes in the customer environment, and the need for a supply chain to react to the environmental change is significant. Fortunately, there are many high-quality established methodologies, including variations of implemented processes available to help a business minimize these types of situations. With many valid solutions available, the challenge can become how to select the suitable approach(s) for your business and its unique supply chain. Learning the Supply Chain Environment There are certainly risks for a company in selecting the methodology or implementing the processes in a manner that is not aligned with the environment. Some common performance gap symptoms can be; over/under investment of capital equipment, resources and inventories; deficiencies in the supply chain ability to be agile; and situations where the supply chain does not reach an applicable state of reliability. To help minimize the risk at Scot Forge we continually invest in the journey of discovery within our supply chain, the learning helps us select the methodology and provides feedback when supporting processes start to reduce effectiveness and need to change. Discovery is focused around learning within the supply chain links; cultures, people, process/systems, how they collaborate and hopefully some level of understanding of variation within the link. Yes, there is no finish line for this goal, but it is one approach to implementing continuous improvement into a supply chain. Metrics can be a useful tool in identifying the need to change they are seldom adequate to identify what needs to change. An early experience from a supply chain implementation that did go well in my own journey is the knowledge that not sufficiently understanding the environment can lead to managing a supply chain at the wrong level. Applying the knowledge gained from learning the environment into a variation perspective of standard deviations and bell curves can help guide implementing methodologies, processes and management at an applicable level supporting an optimizing supply chain that can perform reliably over time. Basic Concept of Theory of Constraints (TOC) Theory of Constraints is a methodology to establish and continually improve on a process of ongoing improvement. It is broken down into five steps, identify the constraint; exploit the constraint; subordinate and synchronize to the constraint; elevate the performance of the constraint; and then go back to the first step and repeat the process. In my experience, to subordinate and synchronize to the constraint can be one of the most challenging behavior change steps in the process. Taking this approach and transferring it into a solution that can be implemented is known as Drum-Buffer-Rope (DBR). Basically, DBR is a method to synchronize the system to the beat of the drum (constraint) by limiting the pace of the non-bottlenecks to match the pace of the drum. A buffer in front of both the drum (constraint) and at end of the system help protect the overall pace and reliability of the system by providing a little slack in the rope. A common example of DBR is a troop marching in a line analogy. If you tie a rope to each member of a troop, the slowest troop member will dictate the pace (Drum). The rope will synchronize the other troop members to the pace of the slowest member (Rope), and by putting a little slack in the rope (Buffer) you will enable the non-drum members to catch up when Murphy (variation) occurs to them, therefore not slowing the progress of the entire troop. Although this can seem like a simple solution, understanding the enterprise environment is a critical component. There can be many scenarios in the supply chain links that are influenced by cultures, people, process/systems, collaborations, variation levels and other contributing factors that might not enable execution. Scot Forge Supply Environment Let's get started by providing a high-level background on the supply chain environment. From a markets perspective, the supply chain provides services and products in several industries like Aerospace, Defense, Mining, Education & Research, Gearing, Heavy Industrial Equipment, Bar Service Centers and Power Generation. Our entire supply chain knowledge and experience are applied to help our customers in these industries by providing services and products in multiple raw material grade classifications, product shapes and manufacturing processes ranging from a few pounds to 300,000 pounds. Our product mix can range from providing a product or service to a single event to making several parts each day across five different Scot Forge locations and several partners locations within the supply chain. This type of environment provides a robust opportunity for learning and gaining both knowledge and experience that can be applied to helping our customers solve their challenges. Implementation of Theory of Constraints (TOC) at Scot Forge I would like to begin by saying that from my perspective there is no one concept that is a silver bullet that works in all environments, all have both positive and adverse implications that must be considered. From a supply chain perspective, what a unique opportunity for a team to develop a system in this type of environment that can perform reliably over time. The potential to provide value back to the customers seems substantial. Based upon the teams learning in the supply chain environment, we felt the methodology to establish and continually improve on a process of ongoing improvement based upon the Theory of Constraint was the best. Concentrating on balancing the flow of the system by spending our efforts to identify the constraint and then subordinating and synchronize the other links in the chain would better leverage our collective efforts. Applying those collective efforts into the five-step process at the constraint versus attempting to respond to the variable local improvements throughout the supply chain seemed more practical. In order to implement the Drum-Buffer-Rope solution, we had to develop a system that enables flexible modeling, analytics and feedback mechanisms to support execution. We routinely spend time weekly evaluating our supply chain by modeling the lowering of the inventory in the system to help us identify the constraint. From an execution point of view, sizing the buffers is accomplished by measuring the variation that occurs at the buffers and their ability to protect the overall throughput and reliability of the system. Discipline and familiarity of executing the Drum-Buffer-Rope solution in our daily collaboration activities and measuring results weekly within the supply chain has helped us gain experience to properly size and adjust the buffers as necessary and not mistake a temporary condition of losing slack in the rope for a new constraint. Which leads to one of the common risk contentions in implementing Drum-Buffer-Rope in these types of environments. There can be a potential risk for the constraint to constantly be changing rapidly without any meaningful activities creating a system that sends false singles making it extremely unreliable and more like the old Whack-A-Mole arcade game than a supply chain solution. Leveraging the knowledge of the team and thinking strategically by asking the question that if we could design the supply chain from scratch where would you want the constraint in the supply chain to be located enabling the largest amount of flexibility that could perform reliability over time for the customers. I know sounds great, but is it reasonable in a capital-intensive setting with several established supply chain links? Our tactic to address this is not perfect, but building a supply chain team built on earning trust and transparency seems to facilitate repeated incremental improvements. I am not sure we will ever really be done with our approach. For several years we have been listening to our customers and continually learning and working on the supply chain. Our experience tells us that continuous improvement within the supply chain is more like a journey than a destination with an ending. How successful has this worked at Scot Forge? We will need to leave that evaluation in the capable judgment of our customers and supply chain partners. Final Thoughts Investments made to attain better knowledge and experience about the different environments and interconnections of the supply chain links can add value in helping to select an optimizing methodology and process. Since there is low probability a supply chain can eliminate Murphy (variation) from the environment, the importance of selecting the appropriate solution is a key contributor to enabling the supply chain to reliably demonstrate performance over time. I would encourage any business to consider how to implement continual learning within the supply chain environment into the path of their work. Focusing on how it interacts as connected links both externally and internally. This is certainly a journey with both bumps in the road and several incremental successes along the way.

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.

Offshore, Marine & ABS FORGING ADVISEMENT ABS CERTIFIED FACILITY Forging For Offshore & Maritime Classification Society Requirements At Scot Forge, we understand that working in the marine and offshore industries often comes with complex rules and regulations, which is why we created the Scot Forge Classification Society (CS) Advisors Group. This group is well-versed in oil, gas and chemical projects and products for marine applications, such as military or government projects, that regularly fall within a Classification Society's requirements. Our highly trained group understands the certification process required to manufacture or construct components for the maritime industry. We are an approved forging supplier, including heat treat and testing processes, for ABS , DNV-GL and Lloyd's Register . When you add the assistance of the Scot Forge CS Advisors to your project, you receive: Design Review – ensuring streamlined manufacturing that meets the Rules of the Classification Societies Supply Chain Optimization – minimizing costs and production delays Third-Party Witness Guidance – eliminating the risk of missed procedure certificates QUALITY ASSURANCE CUSTOMER COMMITMENT Add a Classification Society Consultation If You: Are new to Classification Society requirements Need a trusted partner to deliver your marine parts on time Want to ensure Classification Society compliance WHY DO I NEED A CS ADVISOR? Navigating the seas of maritime rules and required grades can be difficult, especially if your company is new to this market. The governing Classification Society Certifications will mandate that your component meet defined Rules for an application. For example, ABS Steel Vessel Rules part 2-3-7/1 Grade 2; MOU formerly MODU (mobile offshore drilling unit) Rules; DNVGL-OS-B101 Rules for Forgings; Lloyd's Rules for the Manufacture, Testing and Certification of Materials. In addition to knowing the general Rules and Grades for production, knowing the end use of the component is paramount to determine when specific rules apply that may affect how we manufacture the forging as well as special requirements for inspections during manufacturing: Some components must be surveyed and certified during manufacturing. If not completed at the correct manufacturing stages, a Classification Society Surveyor could stop the fabrication/installation processes that occur downstream from your component manufacturer. Your component could be subject to deviation at this point, or even rejection, at a critical time in the installation process, causing severe delays in scheduled repairs or new builds. The Scot Forge CS Advisor will work hand-in-hand with you, providing the expertise you need to eliminate risk. From spec to blueprint, we ensure your parts' manufacturability and compliance for the offshore; oil, gas and chemical; marine; military; government and power sectors. WHAT ARE SCOT FORGE CS ADVISEMENT BENEFITS? Management: Minimize Risks and Costs Scot Forge CS Advisors know working to Classification Society rule requirements cost time and money. Having a partner who comprehends the process can help minimize this cost and mitigate the risk of not meeting requirements. ABS Rules, for instance, require certification inspectors on-site during manufacturing, construction, or fabrication to verify the processes meet standards - and you pay for the time they are on-site. So, it's essential to understand the Rule requirements for your product to identify the stages in your supply chain where inspection and certification should occur. By working with a CS Advisor, you'll gain knowledge from our expertise to make empowered decisions saving your company time and money and minimize the risk of your products not being appropriately certified. As your partner in this process, we will likely ask a LOT of questions to ensure meeting all the design and Classification Society requirements for your component. Our team helps you ask the right questions upstream to gather all necessary project details and better prepares you for future conversations with your customers on new projects. Guidance: Meet Classification Society Supply Chain Requirements Our CS Advisors know it is critical for you to flow-down requirements to your suppliers – and your entire supply chain. We help ensure your requirements are clear and known throughout the supply chain to ensure your components are manufactured under the Rule requirements without delays or added costs. This flow-down is the most crucial aspect to ensure your component is certified accurately. Part Production: ABS, DNV-GL & Lloyd's Register Approved Forging Manufacturer Your CS advisor not only provides you with a dedicated service to help guide your parts through manufacturing, but you also work with a partner that is a uniquely qualified supplier in providing ABS-certified products and materials. At Scot Forge, we are one of the few U.S. companies that have been audited by ABS, DNV-GL and Lloyd's Register and APPROVED and achieved certification as a worldwide forging supplier. We work in ABS and Non-ABS Grades in Carbon Steel, Carbon-Manganese, Various Alloys, Stainless Steel, Aluminum, Copper, Titanium and Nickel Alloys up to 36,300 Kg (80,000 lbs.). WHAT IS A CLASSIFICATION SOCIETY? A Classification Society is an organization that provides classification, statutory certification and services pertaining to maritime safety and pollution prevention, based on marine knowledge and technology. Learn more . A well-known Classification Society is the American Bureau of Shipping (ABS) , chartered in 1862 to certify ship captains; it has helped develop and set safety and quality standards for ships and offshore structures. ABS standards are recognized globally and are used to ensure that the materials, parts and components, and construction of vessels and marine equipment meet established safety standards. HOW DO CLASSIFICATION SOCIETIES WORK? Classifications Societies work with the marine industry worldwide. They develop new technologies for constructing marine vessels and offshore structures, revising and updating the Rules to meet the changing industry needs. The Rules and Grades for component certification provide standards for the design, construction, and periodic survey of marine vessels and offshore structures to promote their safe design and assembly. Materials, parts and components used in the manufacture of marine vessel structures must meet the set standards for the specific application.
