Modern Vehicles and Metal Powders – A Successful Melting Point of Two Booming Manufacturing Sectors

Powder metallurgy - Wikipedia

The automobile industry is one of the largest consumers of metal powder components. Both these manufacturing sectors depend on each other for their advancement and growth. With the new metalworking technology, car makers can produce their designs faster and cost-efficiently. The US automotive industry is known for producing large cars with automatic transmissions. Other countries like Japan and Europe focus on creating lighter versions. No matter the demand, the latest metal powder processing system efficiently caters to all of them. Their production precision and consistency are highly valued. Plus, powdered metal components prove cost-effective due to less manufacturing waste and optimum utilization of original raw materials.  

If you consider the most efficient metalworking technology used today, it’s powder metallurgy (PM). Even though it is a century-old practice, PM has only recently gained the desired attention. In this process, companies apply heat to the metal powders well below their melting point for compaction. 

  • Applications of metal powder technology in the automotive sector

Cars, SUVs, and trucks are built with various structural components produced through PM today. They are used in gearboxes, brakes, transmissions, exhaust, fuel, actuators, sensors, ACs, windshield wipers, etc. This process manufactures high-quality pulleys, exhaust flanges, sprockets, spacers, and other parts. Car manufacturers trust this metalworking process because of its ability to continuously provide tailor-made solutions with exact specifications. You cannot expect this type of delivery from conventional melting technologies, where engineers only have a little freedom over the design and molding of materials.

Another reason that PM materials are the most sought-after is their porosity. Due to the pressure applied on the raw particles during sintering, components develop pores. While not all powder metallurgy parts are porous, those with porosity also become an advantage for car makers. An excellent example is porous bushings, where the lubricating oil is infused to ensure less friction and smooth operability of different parts in the system. The bearing contains a rotating shaft. During rotations, the device exudes the oil to keep both shaft and bearing safe. This characteristic allows the self-lubricating bearings to offer extended service to the systems they work with. 

  • Benefits of metal powders in modern vehicle manufacturing

The contribution of the PM method to automotive is all-pervasive. Most companies are focused on building eco-friendly vehicles. The parts produced through this advanced metalworking process are also green. You already know that traditional metal part manufacturing systems caused plenty of scraps. However, PM restricts or eliminates such wastage, reducing the burden of industrial waste on the planet. Due to the use of fine powder metals, the starting materials are used to their fullest potential. It showcases the process’s resource efficiency. Also, less reliance on shearing, grinding, and other secondary operations significantly reduces energy consumption. The nearly perfect shape of the components produced through PM also decreases the requirement for secondary machining. Simply speaking, you can count on this technology for the following reasons:

  • Net-shape capability,
  • Dense and wear-resistant materials,
  • Customization for precise, complex designs,
  • Desired uniformity,
  • Application versatility,
  • Mass production.

The automotive space is rapidly evolving due to new demands and challenges. Fortunately, modern metalworking technologies like PM continue to rise and adapt to those scenarios as a trustworthy solution.
