1.Sand Casting Mold The oldest types of molds for aluminum casting are the molds that have been used since the time of the Egyptians. These types of molds are made when a cavity is created in sand that is held in a box or "flask". Usually the original "pattern" is made out of wood, metal or other solid material. There is also a core in the sand cavity that forms the center of the casting. Of the different aluminum casting molds, this is one that is used especially for engine blocks, engine manifolds, and other large and heavy castings. 2.Ceramic Mold Another type of casting mold used with aluminum and other molten metals is the ceramic mold. Used most commonly for the investment casting process, the ceramic mold is created around plastic or wax that melts when the mold is fired while it is being created. After the wax is "lost", the mold is then ready to receive the molten metal. This type of casting process is also called "precision casting" because of the precise castings that can be created with this process. 3.Permanent Mold Casting Permanent types of aluminum casting molds are made from metals such as steel and iron. The molten aluminum is forced by gravity or a vacuum into the permanent mold cavity. One advantage of these types of mold castings is that the mold is permanent; unlike sand casting molds which are usually destroyed when extracting the castings once they have cooled. It is also less expensive when used for a large number of castings. 4.Die Casting Molds Die casting molds use steel dies or molds to produce a lot of identical castings. With aluminum, as other metals, the molten metal is forced under high pressure into these types of molds for aluminum casting. This is a versatile process that enables the production of a large quantity of small to medium-size castings. 5.Shell Mold A shell mold is a type of sand casting mold that uses resin to bond the sand into a thin, 10- to 20-mm thick, shell. While the use of these types of molds for aluminum casting produces a better surface finish with more accurate dimensions, this process is definitely more expensive. 6.Plaster Molds Plaster molds are created using plaster slurry that is poured around wax or another type of expendable material such as foam. As the plaster mold is baked, the pattern melts out, leaving a perfect representation of the pattern. Molten metal is then poured into the cavity of the plaster molds. This is another form of "lost wax casting". 7.Graphite Casting Molds Graphite molds and cores are often employed with aluminum centrifugal casting. This process forces metal into the mold and uses rapid chilling to produce a quality of casting not possible with other methods. These are the seven types of molds for aluminum casting most commonly used to produce aluminum castings. Each casting mold is used to produce specific qualities and for different types of casting properties.

Cleaning Die Cast Metal 1. Wipe the die cast metal object with a soft, nonabrasive cloth or rag to remove any loose dust and dirt. You also can use a small vacuum cleaner to remove any loose dust and dirt from your die cast metal object(s). 2. Use a cotton swab to remove any dust and dirt from the small crevices of your die cast metal object. 3. Fill a bowl with 1 cup of lukewarm water, if cleaning a small die cast metal object. If the object is large, fill a bucket with 1/2 gallon of lukewarm water. 4. Dip a soft, nonabrasive cloth or rag into the water. Wring out excess water. Scrub any caked-on dirt and grime gently with the damp cloth or rag. 5. Dry the die cast metal with a dry soft cloth or rag. Waxing Die Cast Metal 1. Apply 1 tbsp. of a nonabrasive carnauba wax to a soft, lint-free cloth or rag. 2. Wipe the die cast metal object with the wax-soaked cloth or rag. Let the wax haze on the die cast metal. 3. Wipe the wax off the die cast metal object with a clean soft cloth or rag. Fold the cloth in half and buff the metal object gently to restore the object's shine.

Die casting is a metal casting process that is characterized by forcing molten metal under high pressure into a mold cavity. The mold cavity is created using two hardened tool steel dies which have been machined into shape and work similarly to an injection mold during the process. Most die castings are made from non-ferrous metals, specifically zinc, copper, aluminium, magnesium, lead, pewter and tin based alloys. Depending on the type of metal being cast, a hot- or cold-chamber machine is used. The casting equipment and the metal dies represent large capital costs and this tends to limit the process to high volume production. Manufacture of parts using die casting is relatively simple, involving only four main steps, which keeps the incremental cost per item low. It is especially suited for a large quantity of small to medium-sized castings, which is why die casting produces more castings than any other casting process.[1] Die castings are characterized by a very good surface finish (by casting standards) and dimensional consistency. Two variants are pore-free die casting, which is used to eliminate gas porosity defects; and direct injection die casting, which is used with zinc castings to reduce scrap and increase yield.
