Casting can also be divided into gravity casting and pressure casting according to the pouring process of molten metal.
Gravity casting refers to the process of injecting molten metal into a mold under the action of the earth's gravity, also known as casting. Gravity casting in a broad sense includes sand casting, metal casting, investment casting, mud casting, etc.; gravity casting in a narrow sense refers specifically to metal casting. Pressure casting refers to the process of injecting molten metal into the mold under the action of other external forces (excluding gravity). Die casting in a broad sense includes pressure casting and vacuum casting of die casting machines, low pressure casting, centrifugal casting, etc.; pressure casting in a narrow sense refers specifically to metal die casting of die casting machines, referred to as die casting. Xudong Precision Casting Factory has long been engaged in the gravity casting of sand and metal molds. These casting processes are currently the most commonly used in non-ferrous metal casting and the lowest relative price.
