    Leave a Comment

    The metalworking process is indispensable in the production of critical components across diverse sectors. As industries evolve, there is a growing demand for custom-engineered powder metal products. This emphasizes the need for advanced manufacturing methods, including powder metallurgy and metal injection molding.

    Selecting the appropriate metalworking technique is paramount in achieving optimal results and ensuring that the components align with the demands of their application. This article will explore the intricacies of metal powder injection molding and powder metallurgy to help you choose the right process for your specific applications.

    The Metal Injection Molding Process

    Metal injection molding (MIM) combines the principles of plastic injection molding with powdered metallurgy to produce complex-shaped metal parts.

    The process begins with blending metal powders and a binder to create feedstock. Then, the mixture is injected into a mold cavity using a molding machine. Post-molding, the part undergoes debinding removing the binder from the green part via thermal or solvent methods. The debound part is then subjected to high temperatures in a controlled atmosphere during sintering. The metal powder particles fuse while the remaining binder is removed, leaving a fully dense metal part with the desired shape.

    MIM-produced components exhibit improved mechanical properties than traditional methods, thanks to fine powder particles and precise sintering that enhances strength and hardness. In addition, the controlled injection molding process ensures tight tolerances and uniformity across numerous components, offering remarkable consistency. It is also cost-effective for mass-producing small, intricate parts precisely, making it ideal for aerospace, automotive, medical, and electronics applications.

    The Powder Metallurgy Process

    Powder metallurgy utilizes metal powders as the starting raw material. They are produced through various methods such as atomization, mechanical comminution, or chemical processes. The chosen raw material is then blended with additives to improve properties like flowability and ease of compaction. Next, the powder blend is compacted using a die and press, creating a green part that is subjected to high temperatures during sintering. This causes the metal compact to molecularly bond, creating a strong sintered component.

    This metalworking technique excels in crafting complex shapes, particularly small gears and miniature parts for planetary drives. Its ability to mass-produce intricate elements cost-effectively enhances the efficiency of these drive systems. The process is also used for producing consumer products and components in the medical field.

    Moreover, powder metallurgy is a resource-efficient method that generates minimal material waste. Its flexibility in processing various metals and alloys allows manufacturers to tailor materials to specific application requirements.

    Powder Metallurgy vs. Metal Injection Molding

    Powder metallurgy and metal injection molding share a common starting point metal powders. However, their fundamental differences arise in handling these powders and the subsequent manufacturing processes.

    Precision and size limitations are also key distinctions between the two processes. While versatile in accommodating various sizes, powder metallurgy may face challenges in achieving high precision. Thus, it often requires additional machining for intricate features. On the other hand, MIM is renowned for its precision capabilities. It can produce near-net shape components with intricate details.

    Additionally, powder metallurgy is well-suited for a broad range of sizes and high-volume production scenarios, making it the more cost-effective choice for mass production. Conversely, MIM is most applicable for small to medium-sized components with complex geometries. This makes it particularly advantageous for applications demanding intricate details and moderate to high production volumes.

    Ultimately, the choice between powder metallurgy and MIM hinges on specific part requirements and key factors such as precision, size, cost and production volume.

    Definition of Sintering

    Sintering is used to provide strength and a stabilizing agent to a material. The sintering of powdered metals is a process in which particles Physically bond under pressure to create a cohesive “green” shape and  when subjected to sintering temperature compacted particles then bond. Typically, the temperature at which the particles are sintered is below the melting point of the powder’s primary material.

    Before the actual sintering process, choosing a powder composition that will produce the desired results is crucial. The powder mixture will contain essential elements — such as copper, iron, molybdenum, and nickel — plus other substances like lubricants and flow enhancers. These will help in improving the powder’s flow into the die. Then, the powder is pressed with extreme force and high pressure to fuse it.

    After the powder has been compacted, the sintering process begins by transferring the parts through a highly controlled Hydrogen/ nitrogen atmosphere  furnace . The objective is to maintain a temperature just below the melting point of the metal, but not completely. Finally, the sintered components are prepared for additional finishing and or secondary heat treatments to achieve the desired properties.

    Benefits of Sintered Powdered Metal Products

    Understanding the Powdered Metallurgy Process

    The Powdered Metallurgy Process

    Powder metallurgy is a process that creates precise and accurate parts by applying a range of pressures to press powdered metals and alloys into a hard tooling . Here are the four fundamental processes in this technique:

    Powder Preparation

    All metals and alloys can be reduced to a powder, regardless of the method utilized. For instance, various techniques can be used to create non-ferrous metal powders in different applications. Meanwhile, almost all iron powders used in producing powder metallurgy structural parts are produced either by the sponge iron method or water atomization.

    Aside from atomization, other procedures for creating powder include chemical reduction, electrolytic deposition, and atomization.

    Mixing and Blending

    To ensure the finished product has the required properties, powders are mixed and blended with other powders, binders, and lubricants. Depending on the item’s specifications, this can be wet or dry. Further, adding alloys and a pressing lubricant is usually included in this process.

    Compacting

    Compressing the powder mixture into the required form or tooling is known as compacting. When done correctly, compacting reduces potential voids and greatly boosts the product’s density.

    Each type of metal powder requires a particular compacting pressure — from 80 MPa to 1600 MPa — depending on its characteristics. For example, the pressure for compacting soft powder ranges from 100 MPa to 350 MPa, while the pressure ranges from 400 MPa to 700 MPa for harder, more resilient metals like steel and iron.

    Sintering

    In this step, the material is heated to a temperature below the melting point of the main component, typically in a protective environment. Liquid phase sintering refers to situations where a minor constituent can occasionally form a liquid phase at the sintering temperature.

    Components Manufactured Using the Powdered Metallurgy Process

    As electronic devices, medical devices, automobiles, and other products adopt smaller and more complex forms, precision fabricated components become more critical. To fit tight spaces and complex geometries, these miniature components must achieve a level of precision not possible through conventional manufacturing. Today, precision fabrication and manufacturing are the most in-demand sectors of industrial manufacturing.

    The Difference Between Manufactured and Fabricated Parts

    Fabrication and manufacturing are two industrial terms associated with producing a finished product. Although the two processes are often referred to interchangeably, they describe different types of processes.

    Fabrication is a process of constructing products from several standardized parts or subassemblies. A good example is metal fabrication, which forms metal structures through multiple processes, including cutting, bending, and assembling. Oftentimes, fabrication processes utilize computer-aided designs (CAD) and computer numerical control (CNC) technology to achieve these multiple assemblies with greater precision and faster turnaround times.

    In contrast, manufacturing involves converting raw materials into finished products. Manufacturing leverages machines, tools, and chemical processing to change materials from their raw form to ready-to-use goods, from start to finish. Examples of industries that perform manufacturing processes are the apparel, chemical processing, electronics, food, leather, printing, and lumber sectors.

    Benefits of High Precision

    High-precision manufacturing is a subset of manufacturing that specializes in producing parts with tight tolerances, often of just a few micrometers. Usually, the tolerance grade of precision machining is IT5, with an accuracy of 10-0.1 μm and surface roughness not more than 0.1 μm. The following are some of the advantages of high precision manufacturing:

    • Reduced turnaround time: High precision manufacturing can significantly improve turnaround times. You can invest in precision machines and skilled technicians to cut down on the number of destinations your products must travel to before final delivery. A contract manufacturer can handle these responsibilities in-house, ensuring you receive high-quality products on time.
    • Minimized human error: Because high precision manufacturing utilizes intelligent, accurate machinery, they eliminate the risk of costly human errors. Unlike humans, computers can follow the same set of predefined operations without errors or inconsistencies.
    • Easy prototyping: High precision manufacturing can help you produce one-off prototypes to full-scale production runs. This flexibility allows you to test and refine prototypes throughout multiple phases of the production process, and you can adjust to changes in niche markets.

    Challenges of the Electric Vehicle Industry

    EV engines deviate from internal combustion engines in some significant ways. For instance, electric motors are far more compact. Additionally, rotation in electric motors is restricted just to the central axis, thus naturally reducing engine vibrations. This creates new challenges for EV automakers. For example:

    • All electric automotive components need to be lightweight and have better thermal management to increase fuel efficiency.
    • Actuated auxiliary system components must be far more compact.
    • Noise vibration harshness (NVH) levels must be reduced even more than usual to address driver expectations and comfort.

    While challenging, these scenarios present automakers with opportunities to push innovation and rethink standard manufacturing expectations. The use of powdered metal components offers:
