Dies (molds)

Two different kind of molds for the parts :
 
  • A complete mold ensures the accuracy and durability of the production; it also allows the fitting of the mold on a wide array of die casting machines ( dimensions are normalized ). It's the best choice if you will reach a good precision and lifespan

  • Cavity retainer blocks* allow for a more cost-effective low-volume production of diecast parts (reusable or not); however, their use is subject to various constraints ;
    - Weight
    - Size
    - Tolerance
    - The complicated application of "sliding cores" or "slides"

    *Cavity retainer blocks are inserted in one of our frames, thus reducing the global cost of the mold.

  • The mold or the cavity retainer blocks are fitted on an injection molding press, the zamak ingots are melted in the crucible at temperatures up to 420 degrees.
