Copper Die Casting

• Product:
  Die Casting
  
  
• Model Number:
  D003
  
  
• Description:
  Aluminum, zinc & copper alloys
  
  Brief introduction: Die-casting is similar to permanent mold casting except that the metal is injected into the mold under high pressure of 10-210Mpa (1,450-30,500) psi . This results in a more uniform part, generally good surface finish and good dimensional accuracy, as good as 0.2 % of casting dimension. For many parts, post-machining can be totally eliminated, or very light machining may be required to bring dimensions to size. die casting, aluminum die casting
