How to choose between low pressure casting and gravity casting

Force casting and low-pressure casting are two different casting methods. They have significant differences in implementation principles, process characteristics, and product applications. First of all, from the perspective of implementation principle, gravity casting is a traditional casting method that relies on the gravity of the earth to inject molten metal into the mold. During the gravity casting process, the molten metal naturally flows into the mold cavity through the gate, where it...

What are the requirements for surface hardness and wear resistance of gravity casting molds?

1. Hardness requirements Mold base hardness: The base hardness of gravity casting molds is generally required to be between HRC35-50. For small and simple molds, the hardness can be slightly lower, around HRC35-40. This is because lower hardness is conducive to mold processing and repair. For example, some gravity casting molds for producing small aluminum crafts can meet basic use requirements within this range, and are convenient for repairing when the mold is slightly damaged, such as repair...
