Aluminum Die casting
09.05.2018 16:10


Aluminum Die casting is actually a method in which molten metal is forced, at higher pressure (2-10 ksi) and velocity (100-200 fps) into a hardened steel die to create close tolerance, thin walled, complex shapes. Depending on casting sizes and also the variety of cavities, hundreds and even a large number of components could be developed each and every hour.

Since the size of the casting may differ from components for watches or instruments weighing only a few grams to automobile engines and transmission cases weighing over 50 pounds, the size from the die
casting gear varies widely. The smallest machines are no longer than a filing cabinet, even though the largest are as large as a tiny residence. Nonetheless, the principles of operation are basically precisely the same. The machine consists of 3 components:

1. The clamping mechanism, which can be ordinarily a horizontal toggle-action press and which holds the die halves together against the considerable opening force on the injected metal.

2. The die casting die itself, which consists of at the least two parts (moving and fixed) containing the impression which makes the casting shape, and which could possibly be fitted with sliding cores to make extra complex shapes. It is commonly water cooled and fitted with a mechanism for ejecting the completed casting.

3. The injection-end in the machine. This is a higher pressure molten metal pump, either hot-chamber kind for alloys for example zinc or magnesium, or cold chamber form for aluminum and brass alloy which would dissolve the ferrous supplies of a submerged pump.

The machines are normally fitted with ancillary devices for example auto-ladles,automatic die lubrication and takeout arms or robots, for removing the castings. Castings could possibly be air or water cooled ahead of being automatically fed to a trimming press to take away runners and feeds. Each of the ancillary gear is synch-ronized to provide a extremely mechanized, automated, higher speed production method with low labor involvement.

Positive aspects of Die Casting

Most casting strategies yield near net shapes which need handful of subsequent operations to match them for service. Similarly, most castings operations are effective in their use of material energy, labor and sources, given that you will discover no intermediate stages in between metal in its molten type as well as the close to net shape casting.

Aluminum Die casting& Magnesium die casting is often a extremely mechanized casting procedure, with high production rates and close tolerances. It produces castings which are generally net shape rather than near net shape; that is, by careful design and good method engineering, components can be developed which demand little or no subsequent operations before being put into services. How close one gets to this ideal depends to some extent on the designer.
