Grass Key Made by CNC Machining are widely used in die-casting metallurgical processes. In particular, in the die-casting process, it can adapt to pressures ranging from 3,000 pounds per square inch to 10,000 pounds per square inch and speeds ranging from 10 to 250 pounds per square inch. The flexibility of CNC machined grass keys makes them suitable for die-casting of a variety of alloy materials, including common industrial alloys such as brass, aluminum, and zinc. In the die-casting metallurgical process, the required parameters (such as pressure, speed, gate design, etc.) may be different when processing different alloys. The grass key can automatically adjust the corresponding working conditions according to the characteristics of different alloys (such as melting point, fluidity, expansion coefficient, etc.) to ensure that each alloy can achieve the best performance in the die-casting process.
In order to ensure the surface quality of the product and extend the service life of the mold, the mold cavity surface of the grass key is matte or satin treated. Through matte or satin treatment, a uniform roughness is formed on the surface of the grass key, which can effectively increase the surface tension between the molten metal and the mold during the die-casting process. This increase in surface tension helps the molten metal better fill every detail of the mold, ensuring that the surface of the casting is smooth and free of defects such as pores and cracks, which is especially important in the die casting of thin-walled parts. Matte or satin surface treatment effectively reduces bubbles, cracks and other surface defects generated during the die casting process. This is critical for the production of precision parts, especially when producing complex shapes and thin-walled parts. Whether in the die casting of brass alloys or other high-temperature metals, surface treatment ensures that the casting has a flat appearance and a smooth surface, greatly reducing defects caused by uneven surfaces. Because the mold surface is smoother, the grass key can achieve higher precision and consistency during the die casting process. This increase in precision makes the dimensions of each casting more accurate, reducing rework and scrap rates caused by unqualified castings, thereby improving overall production efficiency. At the same time, the defect reduction effect brought by surface treatment also helps the production process to be smoother, reducing downtime and unnecessary costs.
For die casting of brass alloys, the die life is about 50,000 times, while for alloys that require higher metal temperatures, the die life may drop to 10,000 times. This high strength and durability enables the grass key to maintain stable performance in long-term production. For alloys that require higher metal temperatures, mold surface treatment can help the mold better adapt to high-temperature operating environments. By reducing mold loss caused by temperature fluctuations, the matte or satin-finished surface can effectively protect the mold from overheating damage, extend the mold life to more than 10,000 times, and ensure long-term stable use.
