What is Powder Metallurgy
Powder metallurgy is an advanced metal-forming process that produces near-net-shape parts for customers requiring large quantities of high-quality, consistently dimensioned, close-tolerance parts. This method enables the creation of highly complex geometries, controlled porosity, and intricate features, making it a proven alternative to casting or forging in many applications. It is essential for manufacturing bushings, bearings, gears, and various other structural parts across multiple industries.
Powder Metallurgy Process
Powder metallurgy parts are produced by filling a forming die with mixed metal powder under specific pressure. The compacted parts are then sintered in a controlled-atmosphere furnace to metallurgically bond the particles. Following sintering, the necessary post-processing steps, including heat treating, plating, and grinding, are conducted to achieve final net shape designs.
Advantages of Powder Metallurgy
  • Fabrication of products with intricate shapes and tight tolerances.
  • High dimensional accuracy and excellent surface quality.
  • Tailored precision production with high efficiency.
  • Control over the porosity of formed products.
  • Cost-effective, reproducible mass production.
  • Finer and denser crystal structure compared to casting.
  • Material utilization exceeds 97%.
Production Process
  • STEP 1
    Raw Material
    The powder metallurgy process uses highly consistent metal and alloy powder. JINWOEN® will work with you to choose the most economical materials that meet your performance requirements. A variety of iron alloys, as well as bronze and stainless steels, are available.
  • STEP 2
    Blending & Mixing
    Blending and mixing metal powders in various combinations to formulate alloys with optimal strength for each powder metal part. We provide metal powders that comply with MPIF international material standards, ensuring the right blend for each specific application.
  • STEP 3
    Compacting
    Pressing the uniformly mixed metal powder under high pressure into the die creates a green (unsintered) compact. Our press tonnages ranging from 15 to 630 tons, with both single and multi-action capabilities
  • STEP 4
    Sintering
    The sintering process heats the green compact below its melting point to achieve structural strength. Our sintering capabilities reach up to 1300⁰ C, allowing us to sinter a wide range of materials, from iron and bronze to stainless steels.
  • STEP 5
    Additional Processing
    We support most of the necessary post-processing to achieve final net shape designs, including heat treating, plating, and grinding. These operations are performed either by us or by local certified suppliers, with all work verified by us prior to final shipment.
