Difference between low pressure casting and gravity casting
2024-08-05
Low-pressure casting and gravity casting are aluminum alloy casting process, low-pressure casting is also known as anti-gravity casting, low-pressure casting. Low pressure casting is also known as anti-gravity casting, low pressure casting. The difference between it and gravity casting is mainly reflected in the following aspects. The difference between the casting principle of operation: the difference between the casting principle of operation: low pressure casting is also known as anti-gravity low pressure casting, so the name of the casting method is through the gas pressure against gravity casting molding, as shown in the figure on the right: through the sealed crucible injected into the gas (usually 0.06 ~ 0.15MPa)), the aluminum liquid in the role of pressure through the middle of the pipeline, the product for the molding of the casting, holding pressure for a certain period of time, the aluminum water cooled in the mold cavity, the aluminum water cooled in the mold cavity. Aluminum water in the mold cavity cooling molding, through the discharge of gas pressure, open the mold, remove the product. Gravity casting refers to the casting of aluminum water through the action of gravity → filling → solidification and contraction → casting, this...
