  • Variability of Feedstock Viscosity and Its Correlation with Dimensional Variability of Green Powder Injection Moulded Components
    In this study, a correlation between green part dimensional variation and feedstock viscosity variation is presented for the powder injection moulding (PIM) manufacturing process. A correlation of an increase in green part dimensional variation as feedstock vis cosity variation increases has been
  • Qualification Method For Powder Injection Molded Components
    The PIM process produces net-shape or near netshape parts at a reduced manufacturing cost; however, significant process and product qualification is required to ensure that the final product is acceptable. The level of qualification depends upon the end use of the product. It could be as simple as
  • Defect-free Sintering of Two Material Powder Injection Molded Components (Part II)
    A defect-free, two-material component can be obtained via co-sintering by suitably altering the powder characteristics or compositions, as demonstrated in Part 1. In this paper, a model to ascertain the suitability of material systems to be co-sintered without defects such as delamination
  • Defect-free Sintering of Two Material Powder Injection Molded Components (Part 1)
    alloy steel or stainless steel can impart toughness, corrosion resistance, and an economical advantage as compared to a component that is fabricated of 100% tool steel. Particulate materials processing offers attractive manufacturing routes such as injection molding, isostatic pressing, and tape
  • Powder metalstake on new shapes
    is an umbrella organization for powdermetallurgy trade organizations. Member companies produce parts using conventional P/M processing, powder forging (PF), metal injection molding (MIM), hot isostatic pressing (HIPing), direct powder rolling, and gravity sintering. The competition's nonferrous grand
  • Design Considerations for Metal Injection Molding
    (less than 22 micron) metal powder hot-mixed with polymeric binders, forming a homogenous mixture. Injection-molded metals include titanium, tool steels, stainless steels, and high-temperature alloys, among others. The hot mixture is cooled and granulated to form the feedstock for specially equipped
  • Blade stopper takes powder-metal prize
    The Metal Powder Industries Federation (MPIF), Princeton, N.J., gave Burgess-Norton Mfg. Co., Geneva, Ill., high marks in its annual Powder Metallurgy (P/M) Design Awards competition for a drum and pulley system used in a blade override system for a power lawn mower. Geneva, Ill., high marks in its
  • Superlative parts crowned at powder-metal competition
    Members of the Metal Powder Industries Federation (MPIF), Princeton, N.J., once again prove inventive powder-metal (P/M) parts can outperform their machined, stamped, cast, and forged counterparts. Metal Powder Industries Federation (MPIF), Princeton, N.J., once again prove inventive powder
