Choose gooseneck in die casting includes material characteristics, heat resistance and mechanical strength, structural design and so on.
When choosing a gooseneck for die casting, we need consider the following key factors:
1. Choose gooseneck in die casting: Material characteristics
Gooseneck mainly uses for hot chamber die casting. And it is suitable for low melting point metals such as zinc, magnesium and some aluminum alloys. If high melting point metals (such as aluminum, copper, magnesium, etc.) are used, gooseneck is not suitable because these materials will damage the gooseneck and other related parts. Therefore, when selecting a gooseneck, it is necessary to ensure that its material can withstand the high temperature and process the chemical properties of the metal.
2. Choose gooseneck in die casting: Heat resistance and mechanical strength
The gooseneck needs to have high heat resistance to withstand the high temperature of molten metal. Usually, the gooseneck is made of gray cast iron, alloy steel or cast steel. In addition, the cylindrical inner cavity of the gooseneck needs to be able to withstand the pressure of the hydraulic injection system, so its mechanical strength is also very important.
3. Choose gooseneck in die casting: Structural design
The design of the gooseneck should ensure that the molten metal can flow smoothly into the mold cavity. Its shape is similar to a gooseneck, hence the name. One end of the gooseneck is immersed in the molten metal pool. And the other end connects to the mold cavity through a nozzle. When designing, it is necessary to ensure that the channel of the gooseneck is wide enough to accommodate the molten metal. And that the connection between the nozzle and the mold cavity well seales to prevent metal leakage.
4. Maintenance and Replacement
The gooseneck may gradually wear out due to high temperature and chemical corrosion during long-term use. Therefore, the gooseneck is usually a replaceable part. When selecting a gooseneck, it should consider the durability and maintenance cost. Then to ensure production efficiency and cost-effectiveness.
5. Temperature control
To prevent the molten metal from cooling in the gooseneck, the nozzle usually needs to be heated to 400-500°C, which can be achieved by gas, electric or induction heating. Therefore, when selecting a gooseneck, make sure it is compatible with the heating system and that the heating process can evenly distribute the heat.
6. Applicability
The hot chamber die casting machine (also called gooseneck die casting machine) is one of the most commonly using die casting equipments on the market. It is suitable for occasions where fast mold filling is required. If production needs have high requirements for filling speed and accuracy, the hot chamber die casting machine and its gooseneck may be the best choice.
When choosing a gooseneck, you need to consider the characteristics of the processed metal. Such as the heat resistance and mechanical strength of the gooseneck, the design structure, maintenance costs, and temperature control. By choosing the right gooseneck, you can ensure the efficiency of the die casting process and the quality of the product.
