1. the process of creating molds made of tungsten carbide

The core of the hard alloy drawing die contracts as a result of the sintering process. The degree to which the core of different batches of the die contracts can vary from one another due to variations in composition, pressing, and the sintering process. The various die parts experience varying degrees of shrinkage during the manufacturing process; as a result, the finished product frequently has the shape of a saddle or bell mouth. The fluctuation in the shape and size of the die is in accordance with the standard of the die, but it significantly exceeds the interference requirement of the die set. Because of this, the outer circle of the die needs to be ground down, which necessitates the use of a specialized fixture that must be mounted on the grinder in addition to the utilization of a diamond grinding wheel.

2. The diameter of the mold core's outer diameter should be less than the diameter of the hole in the mold's innermost layer. Table 1 provides specific information regarding the actual interference level that was experienced during mold mounting. The die set features both the hot pressing method and the cold pressing method as two of its pressing options.

3. The processing of tungsten carbide for the mold sleeve components

The distinctive form of the mold sleeve is the result of turning it on a lathe. The following items collectively make up the control points:

It is necessary for the inner diameter roughness of the mold sleeve to reach 0.80 i in order to obtain a close fit with the mold sleeve.

This will ensure that the interference amount is calculated accurately for each mold by ensuring that the inner diameter of the mold sleeve corresponds to the outer diameter of the mold blank. This should be done for each mold individually.

After the mold sleeve has been installed, the bottom surface of the inner hole in the mold sleeve and the outer end of the mold must be parallel to one another in order for the mold to function properly.

It is recommended that the ellipticity of the inner hole of the mold sleeve be as small as possible, with a value that is no greater than 0. 4.

Cementing carbide onto mold mounting surfaces is the technical term for this process.

The process known as cold pressing involves pressing the blank into the mold sleeve while ensuring that the temperature does not rise above room temperature

It is advantageous in that it does not call for the use of any heating equipment, which results in cost and resource reductions related to heating

The following is a recommendation for an item that has gone through a significant amount of processing:

Wire Drawing Dies made of tungsten carbide can be processed using a machine that has multiple heads and can perform a variety of functions.

Equipment product usage

It is also capable of processing sizing belts with a large aperture, in addition to being used for the rapid reaming of cemented carbide drawings and the processing of the inlet and outlet areas. The eccentricity of the mold inner hole can be repaired thanks to the function of the mold sleeve, which extends from the mold core all the way up to the mold with an 80mm outer diameter. This function can be used to repair the eccentricity of the mold inner hole.

The machining range of the mold aperture is quite large, and an emery needle can be used to rapidly enlarge the hole in order to improve the processing efficiency. This can be done in order to maximize the potential of the mold. In addition, the polishing effect can be improved for molds that have a high number of mold apertures if the molds are polished properly.

Incorporated with a specialized vacuum cleaner that is fitted with synchronous control in order to remove dust at the appropriate time and preserve a clean environment for the apparatus.

Why use Tungsten Carbide Dies?

The hardness of tungsten carbide is almost three times that of steel, and its density is higher than that of titanium. Tungsten carbide is also denser than titanium. This finding is significant for companies that make use of dies because it reveals that a die made of tungsten carbide has a greater resistance to wear when compared to dies made of other materials. This is an important consideration for businesses that make use of dies. Diamonds have a hardness rating of 10, but they are not as versatile as other materials and are obviously a very expensive die material. Diamonds have a rating of 10 on the Mohs scale. On the Mohs scale, diamonds have a rating of 10 for their hardness. In particular, it has the hardest surface imaginable, and its thermal conductivity is the highest of any bulk material. Because diamond possesses these characteristics, the most important industrial applications of diamond are found in tools that are used for cutting and polishing. Because each grade possesses a different collection of characteristics, it follows that each grade is utilized in a distinct sector of the economy. The distinction between each of these grades is established by looking at the proportion of tungsten to carbon present in each of the respective quantities.

Because of its exceptionally high hardness as well as its adaptability to a variety of different uses, tungsten carbide is widely used in a wide variety of industrial applications. This is due to the fact that tungsten carbide is extremely versatile. Because it would take an impossibly long amount of time to compile a list of all of these products, the adaptability component of the equation comes into play at this point in the discussion.
