Principle And Characteristics Of Die Casting

Die Casting is a casting process in which molten metal or alloy is injected into the mold cavity under high pressure, and parts are obtained after cooling and solidification. Here's how Die Casting works:

Mold: The mold is composed of two hardened steel molds, which are divided into dynamic molds and fixed molds, forming the negative shape of the parts. Mold design and production is the key toDie Casting, which determines the shape, size and quality of the parts.

Pressure chamber: A pressure chamber is a container containing molten metal or alloy, divided into hot chambers and cold chambers.The hot chamber is suitable for metals or alloys with low melting point, such as zinc, lead, etc., and the cold chamber is suitable for metals or alloys with high melting point, such as aluminum, magnesium, etc.

Injection system: Injection system is composed of piston, cylinder, valve, etc., used to push molten metal or alloy from the pressure chamber into the mold cavity. The pressure and speed of the injection system can be adjusted according to the complexity and requirements of the part.

Cooling system: The cooling system is composed of water pipes, fans, etc., used to quickly cool and solidify the molten metal or alloy in the mold cavity. water pipes The time and temperature of the cooling system can be adjusted according to the material and thickness of the part.

Ejection system: Ejection system is composed of push rod, spring, etc., used to push out the parts after cooling and solidification from the mold cavity. The strength and Angle of the demoulding system can be adjusted according to the shape and structure of the part.
