Disadvantages of porosity in diecasting. Diecasting is a method of molding molten metal, plastic and resin into whatever shape you desire. In order to do this, a machine will need to pour the molten substance into a container and then force it inside the mold until it cools down. The substance will eventually harden and take the form of the mold it is in. Die casting is commonly used in making toys, instruments, costumes and even costumes. However, there are certain problems in which the products become porous which contributes a lot to its brittleness. This is commonly known as die cast porosity, an unwanted result brought about by air pockets and void space inside the molded material. Products with porosity typically are considered to be of low standard and poor in quality. Here are some disadvantages of die casting porosity.

Air pockets inside a die cast product; can cause weakness of the material. The structure becomes less stable because the density of the particles melded together is not balanced due to small voids of space within. There are also times when diecasting porosity makes the product look less appealing to the buyer or consumer, due to the impression that porosity is a result of low quality machine and materials. Chances of infiltration are also high due to an imbalance in the density of the material. Luckily, there are a lot of ways to reduce the chances of cast die porosity. However, it would also mean an increase in your expense, but it would also increase the chance of more consumers because of your high grade product materials.

Die Casting Porosity

What is Die Casting Porosity? In order for you to know what die casting porosity is, you need to know the die casting basics. The most common form of Die Casting Porosity is a kind of factory defect in which die cast parts contain small pockets of void space and air within the metal, causing it to become porous.

Porosity in Die Casting is the air trapped by the metal inside the die casting parts. To know more, a basic knowledge of the die casting process is necessary. Die casting is a process wherein a particular amount of molten metal is put inside a shot cylinder, then it is applied (plunged) with great force with a piston so as to force the metal into a die cast mold or die cast die. During this “plunging process”, air inside the cylinder is forced along with the metal into the die casting mold. It is a very fluid turbulent process. The air forced into the mold with the metal and the metal already inside the mold is forced out of the mold through a series of gates, vents and overflows.

After this, the metal is left to cool down and harden or freeze inside the mold. The metal is then removed as a die cast part. The same process is repeated over again.

Die casting companies use metals which are non-ferrous, or do not contain Iron, as this is the highest factor for oxidation and rusting. Several examples of non-ferrous metals include zinc, aluminum, lead, magnesium, tin and copper. Kinetic Die Casting only uses aluminum and zinc.

In the worst case, porosity in die casting parts, weakens die casting parts, if the voids or pockets are very large. Porosity typically matters most in pressure tight die casting parts. When the air escapes through a die casting part, it is typically caused by porosity.

The many forms of Die Casting Porosity are caused by many variables:

• Metal and Mold Temperatures
• Material Cleanliness
• Die Cast Mold Design
• Die Cast Part Design
• Die Casting Machine Pressures
• Die Casting Machine Shot Speed
• Die Casting Spray or Mold Release
• Other forms of porosity can be from “shrinkage” or wall thickness.
