Hot chamber die casting products are a process of producing metal parts through a hot chamber die casting machine. The main feature is that the injection system is always filled with molten metal, so it is called a “hot chamber”. Hot chamber dies casting is primarily suitable for low melting point alloys, as the injection system is continuously exposed to high temperatures, making it unsuitable for high melting point metals such as aluminum. Due to the die-casting characteristics and material properties, the hot chamber die-casting process is widely used to produce small and medium-sized parts with complex geometries.<\/p>\n\n\n\n

Hot Chamber Die Casting Process<\/h3>\n\n\n\n

Compared with cold chamber die casting, the hot chamber die casting process requires fewer steps and equipment, and the cycle time is faster, which can greatly improve the production rate, as well as the hot chamber die casting products with higher surface finish.<\/p>\n\n\n\n

The hot chamber die-casting process includes the following steps:<\/h4>\n\n\n\n

1. Close the mold and dip the gooseneck or ladle into a bath of molten metal, usually a zinc-based alloy.<\/p>\n\n\n\n

2. When the gooseneck or ladle is submerged, the piston forces the molten metal up through the gooseneck or ladle into the injection system where it maintains high pressure.<\/p>\n\n\n\n

3. The injection system consisting of the nozzle and the injection sleeve is then opened to allow the molten metal to flow into the mold cavity, filling it completely.<\/p>\n\n\n\n

4. After the metal has solidified, the mold is opened and the casting is removed.<\/p>\n\n\n\n

Materials suitable for hot chamber die casting<\/h3>\n\n\n\n

There are many materiales de fundici\u00f3n a presi\u00f3n<\/a> suitable for hot chamber die-casting. The most important point is that they have a low melting point. When we choose materials, we can choose the appropriate materials according to the application of our products, and see whether the physical properties, mechanical properties, and corrosion resistance of the materials are good. It meets our requirements for the use of piezas de fundici\u00f3n a presi\u00f3n<\/a>, and factors such as production cost and processing difficulty must also be considered.<\/p>\n\n\n\n

The materials of hot chamber die casting mainly include:<\/h4>\n\n\n\n
