Brass hot forging is a process in which brass materials are shaped into the desired shape by external forces at high temperatures. It not only tests the skill of the operator, but also an esoteric science, in which temperature, pressure and time are three crucial parameters, which together determine the quality and performance of brass hot forging products.
Temperature: The soul of hot forging
Temperature is one of the basic and critical factors in the process of hot forging. Brass hot forging usually needs to be carried out at higher temperatures, because brass alloys become softer and easier to shape at higher temperatures. However, the choice of temperature is not the higher the better, but to be precisely controlled according to the specific composition of the brass and the desired final product characteristics. Too high a temperature will cause the brass to oxidize and even melt, while insufficient temperature will make the material too hard to form, while increasing the risk of mold wear. Therefore, finding the right heating temperature to make the brass achieve good plastic state is the initial step in the successful brass hot forging.
Stress: The power to shape
Pressure is a direct means of shaping brass into a particular shape. During the hot forging process of brass, pressure is applied to the heated brass through the die, causing it to flow and fill every detail of the die. The size of the pressure directly affects the accuracy and surface quality of the product. If the pressure is insufficient, the brass may not be able to fill the mold completely, resulting in problems with cavities or insufficiently formed products; excessive pressure may result in excessive material flow, affecting the dimensional stability of the product. Therefore, precisely controlling the pressure to ensure that the brass can flow evenly in the die is another key point in the hot forging process.
