Gravity die casting is used to manufacture casting parts from non-ferrous materials such as aluminium or low-temperature alloys. This method is great for low to medium volume orders and can be an automatic or manual process. Parts are low cost as well, although not as low as the ones in pressure die casting processes. This gives Gravity Die Casting the advantage where subsequent heat treatment of the casting is required although Pressure Die Castings are stronger in the as-cast state. Gravity casting is the process of pouring molten metal into steel or cast iron moulds where there is no force other than gravity. Gravity Die Casting employs cast iron or steel moulds which allow aluminium and zinc castings to be produced more accurately and cheaply than with sand casting, with better surface finish, and better mechanical properties. Gravity Diecasting Our gravity operations work in tandem with our pressure foundry. Here are the Top 10 Tips for designing problem-free casting geometry… This process is suited to high production rates and can be performed at a low cost per unit. This gives Gravity Die Casting the advantage where subsequent heat treatment of the casting is required although Pressure Die Castings are stronger in the as-cast state. These casts also have high strength, and by injecting the metal under pressure there’s minimal metal loss due to spillage. Advantages of this method include lower levels of trapped gas within the mould, which leads to high integrity casts with good surface finish. If you have any further questions about these casting processes or want to discuss how die casting may work for your next project, contact Premier Die Casting online . Both forms of Die Casting employ a metal mould into which non-ferrous molten metal, usually an alloy of Aluminium, Zinc, Magnesium, Lead, Tin or Copper, is introduced. Benefit from our experience - we will be happy to discuss your project! While one may have disadvantages when producing a certain part, the other will not, which is why here at Dean Group we offer both. This method is best suited for larger, thicker parts than pressure die casting, but it can produce great levels of detail. After all, not only are the processes different, but they tend to use different materials and have different end results. This process is a way to produce high volumes of identical, low-temperature metallic components with a great degree of precision and repeatability. One of the most common uses for gravity casting is when permanent molds are going to be used. That’s why we offer both options at NovaCast together with many others including Sand Casting, Investment Casting, Lost Foam Casting and Shell Mould Casting. Common aluminum casting alloys include: A356, A380, ect. The process differs from pressure die casting because there’s no additional force applied, and can also use both metal and sand cores, called semi-permanent mould casting. affect. Sometimes referred to as permanent mould, Gravity Die Casting (GDC) is a repeatable casting process used for non-ferrous alloy parts, typically aluminium, zinc and copper base alloys. The high-pressure filling of the die in Pressure Die Casting allows the alloy to be injected very quickly and, coupled with the highly automated nature of the process, very high productivity can be achieved while the potential for human error is reduced. It is clear then that Pressure Die Casting is considerably more expensive to set up and, due to the complexity of the casting process, is less flexible than Gravity Die Casting. Diversity of our customer base is one of our greatest strengths: a wide range of industries and applications. There is a difference in the quality of casting that can be achieved from each process. Also called a die, the permanent mold is really only economical for those planning on using the same mold numerous times and will need to keep the quality at a constant level.
