  • Causes of Die Casting Mold Failure
    Posted: 05/10/2017 03:11:13  Hits: 26
    1. The damage and failure of thermal fatigue cracking The molding surface and the inner part of the mold will deform under the influences of shock cooling and shock thermal in die casting process. Cyclic thermal stress results in secondary damage to the structure and toughness loss of the structure....

    Posted: 04/25/2017 02:10:50  Hits: 16
    The wear resistance and dimensional stability of the aluminum casting directly affect the machine accuracy and service life; size, accuracy of mold and surface roughness of various pumps' impellers, bodies and inner cavities have direct impacts on the working efficiency of pump an...
  • What's the Benefit of Aluminum Alloy Die Casting after Infiltration Process?
    Posted: 03/28/2017 01:32:58  Hits: 8
    Aluminum alloy die casting infiltration is a new type of casting process, the main principle is to use polystyrene foam to make exactly the same foam model as casts, and then brushed aluminum alloy die casts which was impregnated with special refractory coating, drying, packing, pouring, the metal s...
  • Gas hole standard for aluminum alloy die castings
    Posted: 03/08/2017 03:50:00  Hits: 29
    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 have 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 ...
  • 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 ...
  • Reasons for Pores on Aluminum Alloy Die Casting
    Posted: 07/11/2016 04:57:44  Hits: 21
    Aluminum alloy die casting is scraped because of pores existing. There are various of reasons causing pores. However, figuring out the product quality is quite difficult. How to quickly and correctly take measures for reducing rejection rate due to pores attracts attention from all of aluminum alloy...
  • Surface Strengthening Techniques Used for Molds
    Posted: 04/26/2016 04:36:06  Hits: 90
    At present, molds in China have short service life, high consumption. So, improving service life of mold has already become a priority. The surface treatment on mold has great influences on its service life. Most of damages on mold are caused by improper heat treatment. According to statistics, mold...
