Aluminum Investment castings mold and their applications

Different type of molds can be used for aluminum investment castings where aluminum metal is molten down first then converted into various forms. Few molds may be temporary and others are permanent that are used repeatedly. The same molds can be utilized for different metals and alloys as well.

• Sand Casting Mold

This is one of most oldest molds used to prepare sand castings since the time of Egyptians and china. For this type of mold, cavity is prepared inside sand and original shape is formed with other solid materials. This type of mold is particularly popular for designing engine blocks and other large or heavy castings.

• Ceramic Mold

Another popular type of mold after sand casting is ceramic mold. It is good for investment casting that is generally prepared with wax or plastic around it. The wax layer will melt down as soon as heat treatment is applied over it. After this, molten metal is poured inside ceramic mold and let it to cool down for some time. Mold will be removed once metal will get solidified and converted into desirable form.

• Permanent Mold

These types of casting molds are generally prepared with steel or iron metal and lasts longer. Here, aluminum is melted down first and forced by vacuum or gravity into permanent mold. These molds are not destroyed even after removal of shaped material and it can be used repeatedly. Further, it is most affordable choice when compared to other similar type of molds available in market.

• Die Casting Molds

If you wanted to produce large number of identical shapes then die casting molds are best choice to consider. Here, metal is forced inside mold under heavy pressure and converted into desirable form as it is required. The process is usually good for small to medium sized castings.

Here, we have discussed about most popular various types of molds that are generally used for aluminum investment castings. You can choose any of them based on your project needs and requirements.
