Why Choose TCC Casting?

Gravity die casting replys on gravity other than high pressure to pour aluminum or zinc alloys which makes more simple for cast products. Here are some of its advantages:

  • Parts are taken from mold directly, excellent dimensional accuracy.
  • Compared with sand casting, the surface finish of gravity die cast parts is better.
  • Mechanical properties, especially tensile strength, are superior to those made in sand casting.
  • The wall thickness of parts can be bigger than those made by pressure die casting.
  • Sand core parts could be allowed to creat hollow sections of the parts.
  • The tooling cost is much lower than pressure die casting.
  • Due to fewer production steps and a simpler apparatus, gravity die casting allows for shorter production times and quicker turnaround.
  • Less defects are found by gravity die casting than sand casting.

Of course, gravity die casting is not omnipotent, there are also some disadvantages as follows:

  • The tooling costs are higher than sand casting
  • The thinnest possible wall is between 3 mm and 5 mm thick
  • Not all the metals could be made in gravity die casting, for precision stainless steel parts, investment casting is preferred.

Overall, gravity die casting is cost effective and offers a host of advantages over other techniques. It is a good casting method for its excellent mechanical properties, tight tolerances and quick production capabilities.
