If you are an ordinary person living in an industrialized city, have you ever wondered how many large pieces of metal or small pieces of iron are in our lives? In fact, our lives are closely related to castings, for example, flat bottoms for cooking Pots, knives for chopping vegetables, iron casings for mobile phones. it's actually really easy. The basic manufacturing method is High Pressure Aluminum Die Casting. The casting process refers to pouring molten metal into a sand mold, cooling and forming it, which makes a large shape.

   If you are an engineer supporting a factory production line, then you should have some knowledge of low pressure casting. Metal formed by gravity is only imagined, you know it is not strong enough, you need to add some pressure, so die casting was born. As the name implies, the metal is hydraulically injected into the mold with pressure, and the molten metal is cooled and solidified under pressure to form High Pressure Aluminum Die Casting.

  Pressure casting is a special type of casting. By pouring molten or semi-molten metal into the pressure cavity of the die-casting machine, under the action of high pressure, the molten metal is filled into the cavity of the die-casting mold at high speed, and the molten or semi-molten metal is cooled and solidified under high pressure, A high-efficiency investment casting method is formed. Compared with traditional casting, molten or semi-molten metal is also poured into the mold, and then the cooled metal is cooled and solidified to obtain the required parts. Different from traditional casting: 1. After casting, the molten metal enters the pressure chamber before entering the mold, and then is pressurized into the mold. This allows die casting to fill faster than normal gravity casting. 2. In the process of die casting, there will be a process of boosting and maintaining pressure. By applying pressure, the internal density of the metal after solidification is better than that of traditional castings

  Gravity casting is characterized by poor air discharge, and holes are easy to be found in the metal; there is no shrinkage of the metal, and cracks are easy to occur during the solidification process. Therefore, gravity casting is characterized by low strength and many holes, which is not suitable for bearing parts; High Pressure Aluminum Die Casting features: most of the air is extruded, and the strength is good. All castings are inferior to advanced forgings.
