GRAVITY DIE CASTING

GRAVITY DIE CASTING

Aluminium gravity casting: the ideal solution for your production

The gravity casting is a process well known in the alloys field; it guarantees high accuracy on dimensions for the creation of your components.

It gives higher strength, durabilityvery smooth and precise surface.

Moreover, the aluminium gravity casting is a process that takes less time for solidification compared to other processes and has a reasonable production cost.

 

How does it work?

gravity casting consists in pouring the molten metal (usually aluminium, zinc or copper) into a specific mold by gravity only.

The alloy in solidification will take the shape of the mold and once the part is removed, the mold can be used again, guaranteeing a longer lifetime then the other casting processes.

The gravity casting can be done automatic or manual, it depends on the nature of the parts to produce, and it is a “simple process” because you do not need vacuum, pressurized gasses or other forces.

If you wonderabout the possible gravity casting defects in the production, do not worry: this is one of the best processes to have strong, durable and balanced alloy elements that are used also for components in heavy duty machines, aerospace and in medical devices.

Strengths:

  • Good level of surface finishing;
  • Precision;
  • Multiple parts with a single mold;
  • Different types of alloys;
  • The part can be anodized and hardened (T6);
  • High quality;
  • Price;
  • Excellent Finishing.


Weaknesses:

  • Cost of the mold (usually amortized with medium / large series).


Reference markets:

  • Medical device;
  • Instrument transformer;
  • Design;
  • Automotive.
