As an important component in the industrial field, the excellent performance of tungsten carbide button is inseparable from the exquisite manufacturing process.
The first is the preparation of raw materials. Tungsten and cobalt cemented carbides are usually used to manufacture tungsten carbide button, and tungsten carbide, cobalt and other powders are mixed in a certain proportion. These powders need to be finely screened and processed to ensure uniform particle size and high purity, laying the foundation for the subsequent manufacturing process.
Next comes the powder molding stage. The mixed powder is pressed under high pressure into the initial shape of the spherical teeth through a specific mold. This process requires precise control of pressure and temperature to ensure uniform density and accurate dimensions of the teeth. Although the pressed spherical tooth body already has a certain shape, it is still relatively fragile.
This is followed by the sintering process. The spherical tooth body is sintered in a high-temperature sintering furnace, and under the action of high temperature, the powder particles diffuse and combine to form a strong cemented carbide structure. Parameters such as temperature, time and atmosphere of the sintering need to be tightly controlled to ensure optimal tooth performance. After sintering, the properties of the ball teeth such as hardness, strength and wear resistance have been greatly improved.
In order to further improve the surface quality and accuracy of the ball teeth, subsequent machining is also carried out. For example, grinding, polishing and other processes are used to make the surface of the ball teeth smoother and the size more accurate. At the same time, according to different application requirements, the ball teeth can also be coated, such as titanium plating, titanium nitride plating, etc., to enhance their anti-wear, anti-corrosion and other properties.
Quality inspection is carried out throughout the manufacturing process. From the inspection of raw materials, to the testing of intermediate products in each manufacturing process, to the performance testing of the final product, every step of the way ensures that the quality of the spherical teeth meets exacting standards. Only the spherical teeth that have passed the various tests can be put into practical application.
