    The gas hole standard of aluminum alloy die casting stipulates the principle of grading and rating method of low porosity of aluminum alloy casts, which is applied to sand casting for aluminum alloy. It fits for the outer surface of the casting and the surface gas hole and pinholes after machining. ...
  • The Electroplating of Zinc Alloy Die Casting and Matters Needing Attention 
    Posted: 02/13/2017 01:22:33  Hits: 7
    The main elements of zinc alloy are zinc and alloy, they are both amphoteric metals which has poor chemical stability, easily oxidize and corrode, so zinc alloy cast needs to be electroplated or coated. When it comes to those that don't require a lot of pressure and have complicated shapes, we a...
  • Why is the Hole in Aluminum Alloy die Casting should be Less Than 0.25mm?
    Posted: 01/18/2017 05:13:23  Hits: 10
    We add a lot silicon into aluminum alloy for die casting. When aluminum alloy was condensed in the mold, silicon would float to the surface and form a thin layer of silicon film, which has high hardness and wear resistance. Some designers of OME (Original Equipment Manufacturer) use this feature to ...
