    Product application: Defense 


  • Dewaxed casting

    Use wax to make wax molds to be cast into parts, and then apply mud to the wax molds, which is the mud mold. After drying the mud mold, put it in hot water to melt the internal wax mold. Remove the mud mold from the melted wax mold and bake it into a pottery mold. Once roasted. In general, the pouring port is left when the mud mold is made, and then the molten metal is poured into the pouring port. After cooling, the required parts are made.

     

    The advantages of this casting process are as follows: the surface roughness antigen of casting parts is well controlled, suitable for complex structure, multi-cavity products, the dimensional accuracy of castings is higher than that of sand casting, gravity casting, low pressure casting (low pressure casting), Vacuum negative pressure casting of gypsum shell (vacuum casting)

     

    Air tightness test method is

    Put into the box NITROGEN and put it on 200mBar, stabilize the box for 30min.
    After words we leave the box for 2 hours on pressure, the box can max drop for to 195mbar. Normally the box doesn’t drop when it’s closed.
