Permanent mold casting is a process that includes the use of permanent
or reusable molds. Chill casting is another term used to refer to the same
process. In this article, we will learn about this process. Read on to find out
more.
In permanent mold casting in aluminum die casting mold,
there is the involvement of a two-piece mold. However, these pieces are made up
of iron or steel and these parts are put together. To receive molten metal
there is a hole on the top of the mold. Both of the pieces are separated once
they are cooled down. In case the casting structure is too complex there are
high chances that the mold has some slits on it. They have to perform tooling
to fix this problem.
They need to preheat the mold at the beginning of the process. From the
mold this stage removes moisture and in the molten metal, it maintains the
temperature. Another advantage of preheating is that thermal expansion prevents
the mold from damage. When the molten metal is poured into it this expansion
happens.
To pour molten metal in the mold from aluminum die casting mold
manufacturers, different means are used. However, there are a few common
methods. This method is the best as far as cost is concerned as it doesn't
require a lot of equipment.
In such a case, into the mold, the liquid is inserted with pressure. The
vacuum insertion method can also be used at alternate times. The right method
is used based on the needs so that the best results can be achieved.
Special Features of Permanent Mold Casting
- The need for
other machining operations is reduced
- It allows the casting of thin walls
- It even
allows the casting of other pins and inserts
- The
production of lighter parts is also allowed
- It has some
better mechanical characteristics
- Great
dimensional accuracy is offered
- It is
economical and cost-effective
- Unlike other
methods, it offers a smoother surface finish
