The Advantages and Disadvantages of Wet Green Sand Casting
Wet green sand uses clay and moderate
amount of water as the main binder, and it is closed and poured
directly under wet condition after molding. Wet green sand casting
has a long history and wide application. And this article will
mainly introduce both the advantages and disadvantages.
Wet green sand casting mainly has five advantages:
1. The clay resource is very rich and cheap.
2. Most of the wet green sand used can be recycled by appropriate
treatment for reuse.
3. The manufacturing cycle is very short and the working-efficiency
4. The sand mixed can be used for quite a long time.
5. The sand can still suffer a small amount of solid deformation
without damage after it is pounded, which is very favorable for
withdrawing and core setting.
The disadvantages of wet green sand casting are:
1. When mixing sand, you need to coat thick clay slurry on the
surface of the sand, and you need to use high-power devices with
rubbing function, otherwise, it is impossible to get good quality
2. Since after mixture, the sand has very high strength, when
molding, the sand is not easy to flow, and it is difficult to pound,
and hand molding is not only laborious but also needs certain
skills, while machine molding needs complex and large device.
3. The stiffness of the mold is not high, and the dimensional
accuracy of castings is relatively poor.
4. The castings are prone to having washed sand, slag, porosity and
other iron casting defects.
Though green sand casting
has its disadvantages, the advantages outweigh the disadvantages,
and with the development of green sand casting, more and more
methods are taken to improve the castings, therefore, this
traditional process is still widely used to produce a large amount
of qualified castings.
