  • Graphite Mold Casting Process Proves "Picture Perfect" for High-Tech Camera-Housing (.pdf)
    A Graphicast customer describes the steps followed to successfully employ the graphite mold casting process.
  • Permold Casting Tutorial (.pdf)
    The Permold process, also known as Gravity Die-Casting, produces large number of castings via a non-destructible, metal mold. Specifically, molten metal is poured into a passageway leading to the part cavity whereupon solidifying, it is ejected from the Permold.
  • Investment Casting Molds
    Handling Procedure: Investment casting molds in a "cup up" orientation are gripped and picked from an incoming cart, the molds are then transferred away from the cart and filled with water for leak testing, after testing is completed the molds are inverted 180º to our the water out. After water has
  • An example of mold tolerances
    This housing for a heavyduty portable magnetic drill weighs 7.16 lb and is highly cored to reduce the material removed during secondary machining. Permanent-mold casting is said to easily mold this complicated double helix, 83-lb auger mechanism for a juicing machine. Secondary finishing gives
  • Faster, more predictable die casting
    deburring or chasing. Similarly, uniform wall thicknesses in a design distribute stresses more evenly. And precision tooling used in hot-chamber die casting helps eliminate secondary finishing or machining -- net-shape parts exit the mold "flash-free. " Net-shape manufacturing is one of the main
  • Mold Material - Lessons in the Use of Electroformed Nickel Tools - 05/05
    tools of various applications, the plating might be 0.080 " to 0.250 " thick and free standing or mounted in a steel frame with a filled epoxy mass casting for load bearing. An average nickel shell for an instrument panel slush mold tool would weigh about 150 pounds. A completed RTM tool
  • Casting Densification Process
    Alcoa has developed a method designated the Alcoa 359 Process, which significantly improves the fatigue strength of aluminum sand and permanent mold castings. In achieving this improvement, the process substantially eliminates the microporosity normally encountered in aluminum castings as a result
  • Permanent Mold Castings: Pathway to Quality
    The casting approach enables metal to be put where it is required by part function, in contrast to other processes that produce shapes more rigidly constrained by the limitations of the production process. In selecting a method of producing parts, many factors must be taken into account. A major

  • Casting Design and Performance
    After the positive shape of part is assembled into a cluster, the cluster is coated with a thin ceramic slurry, dried, and placed into a flask (Fig. 9) for investing of a casting mold consisting of unbonded sand or other molding media.
  • Microstructure and Properties of Ductile Iron and Compacted Graphite Iron Castings
    … molding and core sands is defined as a treatment of spent molding and core sands allowing to recover at least one component of properties similar to the properties of the fresh component and to reuse it for casting molds and core production.
  • Production technique
    The pilots through casting of metallic casting materials represent the influence taking on the state change liquidly! that fixedly runs off in a casting mold in dependence from the time.
  • Elimination or Minimization of Oscillation Marks: A Path To Improved Cast Surface Quality
    The highly transient nature of the phenomena in continuous casting molds requires very powerful data acquisition equipment which was unavailable until relatively recently.
