Additional Technical Die Casting Terms
Additional Technical Die Casting Terms. The pillar of modern manufacturing industries nowadays is the metal forming industries. The process of die casting aluminum metals produces tons of precision metal parts, primary products and by-products. Besides the basic terms used in die casting manufacturing procedure, it is important to know additional technical die casting terms.
Dowel Pin
It is a semi-permanent guide pin primarily used to maintain alignment between cavities in two halves die.
Eject
It is the process of pushing the hardened casting out of the die.
Gooseneck Machine
It is also known as Hot-Chamber Machine. It is mainly used with zinc, tin and lead-based alloys.
Hot Short
It is a term used to describe an die cast alloy which lacks ductility or has a tendency to become brittle at elevated temperatures. Materials of such characteristics do not have enough tensile strength to resist stresses resulting from cooling.
Intergranular Corrosion
It is a type of corrosion characterized by cracking along grain boundaries of metals or alloys upon exertion of tensile stress. Local difference in the composition common in alloy castings is often the cause of this circumstance.
Shot Blasting
It is a process of cleaning metal where a fluid blast off abrasive steel balls against the surface for a clear finish.
Shut-Off
It is a point where the surfaces of the two halves die are fitted together to stop the flow of liquefied metal between them.
Sprue
It is a hole in a die casting tooling in a hot-chamber die casting machine which is the primary entry point of molten metals towards the chamber.

What is a Die Casting Draft Angle and Why is it Important?
What is a Die Casting Draft Angle and Why is it Important? Hundred million tons of metal products, precision metals and metal parts are produced each year. The aluminum die casting industries contribute a massive volume of these metals through the application of advanced technologies and methodologies. This includes giving importance to applying the right Die Casting Draft Angle in producing optimum quality and high volume metals parts.
Draft Angle is an important requirement in the die casting process. It is described as an angle or amount of slope that is incorporated into a wall of a die casting mold making the opening of the die cavity wider than its base. It is also known as the draft.
Die casting molds with surfaces perpendicular to the direction of ejection can damage the product and the mold. The metal formed will stick to the mold and an ejection by force and pressure causing an immeasurable damage. Additional cost will be incurred to produce another mold if it is reusable. Hence, a small angle must be applied I all surfaces.
During the cooling process, the castings will shrink towards the core at an acceptable rate. This is the reason why drafts are higher on the inner surfaces of the die. To avoid high pressure in castings, the inside corners must be protected with fillets.
The die cast Draft Angle requirement varies with the specific surface, the depth of the surface and the kind of alloy used in casting. To facilitate the ejection of die castings, the surfaces of the angle must be specified.
Because of the importance of Draft Angles in in aluminum die casting, Die Casting Manufacturing Companies employ specialists to give due consideration to such dimensional factors.

Maximum Protection
Maximum Protection. Steel is the preferred material to be used as protection for any item. It is relatively cheap but is very sturdy compared to other materials. The only problem encountered with using steel is the weight of the material. Steel, especially compounded ones, is very heavy compared to other materials. This makes it difficult to carry around even if the item contained inside is small. For this reason, it is best to use an aluminum box instead of a steel box with a die cast tool.
Aluminum boxes are containers that are as durable as steel boxes but possess only half their weight. These boxes are used to store items of any kind and value although they are more commonly used to store electronic items. The reason for this is that aluminum boxes prevent the electronic items from malfunctioning due to external magnetic energy. They come in different sizes to cater to the different types of electronic devices. They also come in different colors to give way to the preference of individuals. They can be purchased in DIY stores, hardware stores, and online stores.
Aluminum boxes usually come as DIY kits so that owners are able to customize the enclosure to fit their devices. This is not often the case however since device manufacturers make their own enclosures to fit their devices. In cases where an aluminium box does not fit a device perfectly, contacting manufacturing plants is the most advisable option. Manufacturing plants tend to have schematics of popular devices which means that they can create an aluminium box that will fit the device perfectly.

Tooling Used For Aluminum Die Casting
Tooling Used For Aluminum Die Casting. Tooling is a major requirement in aluminum die casting. During the process of casting, the softened molten metal is injected through custom tooling. The die is then cut into two halves. There is the cover metal die which is mounted on the stationary based platen and the ejector type die, which is actually mounted to a movable platen. Such a design provides the die with the ability to close or open along parting lines. Once the hole is closed, the two die halves will form a type of internal cavity which is filled with hot molten metal in order to form its final casting.
The cavity is formed through 2 inserts. The two inserts are the core and cavity inserts. They are inserted into the cover or ejector die. The cover die provides movement or flow of the molten metal through the injection area. Through a small opening and the cavity, the molten metal will be able to move easily. The ejector die also includes a support plate and a small enclosure called the ejector box, which is well mounted onto the area of the platen. When the clamping separates the 2 halves of the die, the clamping bar will be pushing the ejector plate into the ejector box. The clamps will then push the pins of the ejector to the molded part. The added pressure will eject the clamp from its core insert. In order to perfect the process, multiple cavity die is often utilized and in this type of process the two halves of the die will form several types of identical cavities.

Die Casting Porosity
Die Casting Porosity and Its Causes. Die Casting porosity is one of the most common-place defects in the die casting manufacturing industry. What is die casting porosity? Die Casting porosity is a type of die casting factory inadequacy in which the die cast parts have minuscule spaces which covers air within the metal – later, the die cast parts become porous. The porosity of die casting parts could deteriorate the parts itself if the spaces or holes are very big.
To plainly understand the causes of the porosity one must know the rudimentary of the die casting procedure. In a nutshell, die casting procedure includes molding molten metal by inserting it inside a squat cylinder, and then a great force is applied by a piston connected on the cylinder, pushing the melted metal so it would take the form of the die cast die or die cast mold. Throughout this process, the metal is forced along with the air inside of the cylinder to the die casting mold.
Die casting porosity could be extra by numerous 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 tool.
•
Design of the die casting part.
•
The shot speed of the die casting machine utilized.
•
Die casting mold release or die casting spray
Die casting manufacturers use metals that are non-ferrous or metals that don’t have iron. It is because iron content is the principal reason for oxidation and rusting. Non-ferrous metals comprise of magnesium, tin, lead, copper, zinc and aluminum.
