At PSM Industries, Inc., with our Pacific Sintered Metal Division, we specialize in creating powder metal (PM) parts that deliver strength, precision, and reliability for a wide range of applications. As trusted powder metallurgy manufacturers, we’ve spent decades refining the process of turning fine metal powders into finished components that meet exact specifications. If your project requires parts that are durable, consistent, and cost-effective, our powder metal manufacturing process is built to deliver.
Selecting the Right Metal Powders
Every high-quality PM part starts with the right raw material. We carefully select metal powders based on the mechanical properties and performance you need. Options include carbon steels, stainless steels, low-alloy steels, copper, and bronze. Particle size, composition, and purity matter because they affect the density, strength, and durability of the finished product. Our team makes sure every batch meets strict quality standards so your parts perform reliably from the first use.
Blending and Mixing
After selecting powders, we blend them to achieve consistent properties throughout the material. This step often includes adding small amounts of lubricants or binders to improve flow and compaction. Uniform blending is crucial for making sure each powder metal part has even density and predictable behavior during pressing and sintering. It’s a step that seems simple but has a big impact on the quality of the final part.
Compaction or Pressing
Blended powders are shaped by pressing them into steel dies under high pressure. The result is a “green” part—a compacted shape that holds together but isn’t fully strong yet. Pressing allows us to form complex geometries and reduce machining time. This step gives you near-final shapes with excellent dimensional accuracy, saving material and labor costs. Once pressed, the green parts are ready for sintering.
Sintering
Sintering is where your powder metal parts transform into solid, durable components. We heat the green parts just below the metal’s melting point. At this temperature, particles bond together through diffusion, forming strong, dense sintered metal parts. Sintering defines the mechanical properties, strength, and wear resistance of the finished component. Our controlled sintering process ensures consistent results across every batch.
Secondary Operations
After sintering, some parts undergo additional operations to meet specific requirements. These can include machining, grinding, heat treating, surface treatments, plating, or oil impregnation. These steps improve tolerances, surface finish, and functionality. By combining sintering with selective secondary operations, we can deliver sintered metal parts that fit directly into assemblies without further modification.
Quality Control
Every part leaves our facility with full inspection and testing. We check dimensions, density, hardness, and mechanical properties to ensure each PM part meets your standards. Consistency is critical, especially for high-volume production or components used in safety-critical applications. As experienced powder metallurgy manufacturers, we take this step seriously to give you confidence in every part.
Applications and Industries
Our PM parts serve industries where reliability matters: automotive gears and bushings, aerospace components, medical instruments, industrial machinery, and electronics. Parts produced through our powder metallurgy process are cost-efficient, durable, and capable of complex shapes that would be difficult to achieve with other manufacturing methods.
