What is Permanent Mold Aluminum Casting?
In Permanent Mold Aluminum Casting a reusable metal mold is used in place of an expendable sand mold. The mold is coated with various refractory paints to protect the mold from the molten aluminum and also helps to control solidification . Using our proprietary molding machines the molds are held closed hydraulically with over 20,000lbs of force during the casting process. With the Alcast Company electro magnetic low pressure process, the mold is then filled from the bottom for a set amount of time, the casting is then allowed to solidify before being removed from the mold. We use the process to produce fan blades, brake calipers, valve bodies, master cylinders and more. Reusable steel cores can also be added to the permanent molding process to produce more complex parts. Alcast Company usually uses smaller pneumatic cylinders to insert these reusable cores before casting the part and also to remove them before removing the aluminum casting from the mold. Using these reusable steel cor
