manufacturing tips: five casting technologies to consider for yourdesign - midwest die casting
The foundry industry has been surrounded for the past 10 years, perhaps more.
In fact, in Philadelphia, there are at least 30 large foundry factories in more than 60 years.
There is only one major producer now.
But the casting process is developed worldwide.
It is the backbone of making most of our metal products.
Let's take a look at the advantages and disadvantages of the five casting processes. 1)
Sand casting is one of the oldest casting processes.
As its name implies.
Replace them with a fine sand.
Pour metal (gravity feed)into the mold.
After the material is cooled, the frame is released and the sand disappears.
Leave the parts on the ground and clean them.
This type of casting is the most basic.
But it has a huge advantage.
This is the cheapest way to make large castings, and may be the only way.
A 50-pound casting.
, Made up to thousands of pounds using this method. 2)
Compared to sand casting, this process produces more precise and complex components.
The IC process has been used to make jewelry for hundreds of years.
For investment casting, aluminum processing tools are used.
The wax is then injected into the tool.
The tool then generates a precisely copied wax model (
Some allowance for contraction)
Part to be made.
Then assemble the wax with other wax on the tree.
According to the size of the part, each tree becomes 10-200 pieces.
After the tree is fully assembled, immerse in the 5-layer ceramic slurry.
After the ceramic hardened, the wax melted from the tree.
Now you have a tree ready to pour the alloy in.
This is a gravity feed process suitable for various alloys
Black and non-ferrousferrous.
The investment casting gives you a very precise casting and the finish is very smooth.
It is perfect for making parts that weigh less than 10 lbs. 3)
Graphite mold casting this is also a gravity feeding process where graphite is used to make the mold for this process. A cavity(
Negative model of part)
It is processed into two large pieces of graphite.
These two halves align with each other and put them in one and a halfPress automatically.
The process produces precision castings, which are very good for large thin covers and instrument bases.
Thus saving a lot of processing costs. 5)
This is a relatively new process (30 years old)
Used to make small parts.
The tool for this process is almost exactly the same as the plastic injection molding tool.
Once the green parts are formed, they are absorbed and sintering.
This process has made progress in the field of medical devices.
Its main drawback is that the tools are very expensive, more than $25,000.
But it does give you a lot of precision and a relatively low price for high volume components. 5)
This process also uses a pressure-pressed cast steel hardening tool.
$25,000 or more is a typical price for die casting molds.
However, this is by far the most cost-effective method for casting aluminum, zinc, and magnesium components.
Die casting is a highly automated process and therefore requires a lot of money.
But there are similar machines all over the world.
Make the die casting process a global business.
If you have any further questions about developing casting, there are a lot of great resources on the Internet.
