Die Casting Porosity and Its Causes. Die Casting porosity is one of the most common defects in the die casting manufacturing industry. What is die casting porosity? Die Casting porosity is a type of die casting factory defect in which the die cast parts have tiny spaces which contains air within the metal – hence, the die cast parts become porous. The porosity of die casting parts could weaken the parts itself if the spaces or voids are very large.

To clearly understand the causes of the porosity one must know the basic of the die casting process. In a nutshell, die casting process involves molding molten metal by placing it inside a short cylinder, and then a great force is applied by a piston connected on the cylinder, pushing the molten metal so it would take the shape of the die cast die or die cast mold. During this process, the metal is forced along with the air inside of the cylinder to the die casting mold.

Die casting porosity could be contributed by many factors like the following:

• Die casting machine pressures.

• Temperature of the metal and the mold.

• The cleanliness of the materials used.

• Design of the die casting mold.

• Design of the die casting part.

• The shot speed of the die casting machine used.

• Die casting mold release or die casting spray

Die casting manufacturers use metals that are non-ferrous or metals that don’t contain iron. It is because iron content is the main reason for oxidation and rusting. Non-ferrous metals include magnesium, tin, lead, copper, zinc and aluminum.

Sand Casting Compared to Die Casting. If you are wondering which is better- sand casting or die casting – then this is the right article for you. Whether you want to know about sand casting or die casting advantages or a comparison of both, this article will certainly help you.

In order to have a clearer view of what is better, you must first know what these two methods are all about. Sand casting, as its name implies, forms its mold with the help of a pattern or model which is pressed into a kind of sand mixture. Die casting on the other hand uses hardened tool steel as a mold in making its cast parts.

Both processes are good choices of metal casting method. It just depends on what kind of metal parts you plan to cast or produce. For large hollow metal parts like automotive cylinder heads, sand casting is usually used. For smaller and more detailed metal parts, die casting is the more ideal process. The casting weight range for sand casting is actually unlimited while die casting ranges from 1oz up to 20 pounds.

When it comes to mass producing parts, which requires intricate details and smooth surface, die casting is the more preferred method. It is because die casting process has a dimensional tolerance of as low as .001 inch, while sand casting has a minimum of .010 inches.

Money-wise, initial expenses for die casting are more expensive, especially the die cast tooling than the initial costs used for of sand casting. However, in the long run, die casting has a lot cheaper labor cost compared to the labor cost incurred by sand casting.
