die casting process overview

When the metal melts
This process is called die casting, which is highly pressed to form a mold cavity.
This process is basically used to form different desired shapes from hardened metals.
At these times, however, due to low cost and light weight, alternatives to these types of parts have slowly replaced these metals.
But of course, the effectiveness of hardening and forming metals can never be replaced.
This process started in the early days, using the low pressure injection method first.
But over time, with the advancement of technology, the use of high-end high-pressure technology, such as the two most common extrusion casting and semi-extrusion casting
The solid casting process is more effective than the previous method.
Prior to that, only tin and lead were involved in the process;
But today, even copper, alloy and magnesium can already be high with the famousPressure method.
Mold and die casting type in fact, the mold consists of two parts of the mold, that is, the top out mold and the fixed mold.
These molds are made up of Alloy Tool Steel.
In addition, there are four types of molds;
That is, single cavity, multi-cavity, unit mode and combined mode.
As the name implies, the first type is a single cavity for the production of components.
The second is a multi-cavity mold for making multiple equal or matching parts.
The third type is the unit mold, which is used to produce various types at the same time.
Finally, the combined mold is used to create many different parts for the assembly.
The manufacture of die-casting products is done at high speed and pressure, in which case the molten metal is injected into the mold.
With high pressure and high speed, smooth and accurate casting can be produced.
The pressure applied to the material should be held to the shape required for the metal to form and solidify.
After the metal is hardened, open the mold immediately and take out the output product.
Like other processes, the die casting method has both advantages and disadvantages.
The following overview: Benefits of Die Casting: die casting parts have longer service life, tolerances and accurate dimensions compared to other castings. Process economy. Mold can be re-processed
It can be done by the automation process disadvantages of the die casting: the initial cost is quite expensive. There is a casting weight preference between 30g. The size of the casting product should be less than 24 inch or 600mm. The process is limited to the automation mentioned above for high elastic metal die casting as an advantage, and the process can indeed be fully automated.
With the improvement of modern processes, there are machines that ensure quality consistency.
The whole automation process covers the whole die casting process, including metal lubrication, pouring metal into the chamber. This auto-
The process can be done in two different ways
Methods of hot and cold rooms.
