CFS’ gravity die casting foundry is located at the Ningbo, China. This casting type is ideal to produce small to medium-run components in Aluminium or other non-ferrous alloys. Aluminium Gravity Die Casting is a permanent mould casting process that produces aluminum parts in good surface finish, intricate shape and little subsequent or no machining is required.
Why use CFS’ Gravity Die Casting?
Gravity die casting replys on gravity other than high pressure to pour aluminum or zinc alloys, this makes it more simple to 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.
