The Principle Of Lead Die Casting

In recent years, lead die casting has been used more and more in daily life.

In recent years, lead die casting has been used more and more in daily life. The die casting process is a process in which the three elements of die casting machine, die casting mold, and alloy are organically combined and used comprehensively.

The process of filling the cavity with metal during die-casting is a process of unifying process factors such as pressure, speed, temperature, and time. The influence of mold structure design, heat treatment process, mold manufacturing, and mold assembly on the life of lead alloy die-casting molds.

The principle of the die-casting process is to use high pressure to press molten metal into a precision metal mold cavity at high speed, and the molten metal is cooled and solidified under pressure to form a casting. Cold and hot chamber die casting are two basic methods of the die casting process. In the cold chamber die-casting, the molten metal is poured into the press chamber by a manual or automatic pouring device, and then the injection punch advances to hydraulically press the metal into the cavity. In the hot chamber die casting process, the pressure chamber is perpendicular to the crucible, and the molten metal flows into the pressure chamber automatically through the feed port on the pressure chamber. The injection punch moves downward to push the molten metal into the cavity through the gooseneck. After the molten metal has solidified, the die-casting mold is opened and the casting is taken out to complete a die-casting cycle.

The principle of zinc die casting is the same.
