  • How Expanded Metal Is Made
    Expanded metal is made by a process of slit and stretch. A precision die slits and stretches the material in a single operation. The material is then processed through a set of rollers which adjusts the final thickness. The shape, form and number of openings are dictated by the particular tool used
  • 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
  • The Effect of Process Characteristics on Metal Fill and Defect Formation in Aluminum Lost Foam castings
    density. The pre-expanded beads are then blown into a mold cavity where they are heated with steam to further expand and fuse together as they form the desired shape. The steam used in the molding process is supplied to the cavity by way of holes positioned throughout the mold. The steam is typically
  • Corrosion Control
    Heat removal is one of the most important functions of a metalworking fluid. Effective heat removal yields good tool life and dimensional accuracy of parts. Water has greater capacity for removing heat than oil. However, water alone in contact with freshly machined metal leads to corrosion. Thus
  • New frontiers in superalloy development
    specializing in inorganic synthesis and characterization, modeling, and radiation science have designed a radical system of experiments to study the science of creating metal and alloy nanoparticles. The lightweight, corrosion-resistant materials the team creates are needed for weapons casings, gas
  • Electrohydraulic Controls Boost Thermal Drilling
    Melting holes is sometimes a better option than drilling them. Thermal drilling relies on friction from a carbide bit to melt and extrude metal and form a hole. The process leaves a thicker lip around the edges of holes than with conventional drilling, providing more metal for stronger welds
  • Medical Device Link .
    fuses, or bonds, two metals to form a unified piece. In EDM, however, the electrode (typically made of brass, copper, or graphite) creates a spark that is used to melt or vaporize a metal surface layer, on a localized level and with minimal heating. The result is an extremely precise part
  • Medical Device Link .
    Metal alloys, the first widely used biomaterials, are no longer specified solely for their strength in orthopaedic applications; they also play an active role in treating disease. The invention of the coronary stent in 1969 made implantable metal a vital tool for cardiology applications, and has
