Advantages of Aluminum Casting
  • Materials used in a wide range, and almost materials found on spec sheet can be casting.
  • 5 head, 6 head, 7 head materials through wax-lost casting process can be treated by anode and cathode.
  • Mechanical properties are better than die-casting and recasting.
  • Suitable for small amount and diversity.
Advantages of Aluminum Die-Casting
  • Product has high dimensional accuracy.
  • Tool life up to 200 thousand times or more.
  • To reduce the proportion of post-processing mechanism.
  • Suitable for mass production.
