The difference between cemented carbide molds and ordinary molds

The main difference between carbide molds and ordinary molds is their wear resistance and hardness. These two properties play a vital role in the mold’s service life and processing efficiency. Because of their excellent wear resistance and hardness, carbide molds are widely used in various high-load, high-precision stamping and forming processes.

First, let’s discuss the wear resistance of carbide molds. Cemented carbide is a composite material composed of refractory metal carbides (such as tungsten carbide, titanium carbide, etc.) and metal binders (such as cobalt, nickel, etc.). This special composition makes the carbide extremely hard, wear-resistant and corrosion-resistant. Carbide molds can maintain their dimensional accuracy and surface finish during long-term use, thereby ensuring the quality and stability of stamping parts.

In comparison, the wear resistance of ordinary molds is relatively poor. Ordinary molds are usually made of carbon tool steel, alloy tool steel and other materials. Although these materials have certain wear resistance, they wear quickly during high-load and high-speed stamping processes, which can easily cause a decrease in dimensional accuracy and deterioration of surface quality.

In addition to wear resistance, hardness is also an important difference between carbide molds and ordinary molds. The hardness of cemented carbide is much higher than that of ordinary mold materials, which allows cemented carbide molds to maintain good stability when subjected to high pressure and high temperatures. Ordinary mold materials are prone to softening, deformation and other problems in high-temperature or high-pressure environments, which affects the service life and processing accuracy of the mold.

In practical applications, cemented carbide molds are widely used in precision stamping and forming processes in the automotive, electronics, aviation and other industries due to their excellent wear resistance and hardness. Ordinary molds are more commonly used in situations that do not require high wear resistance and hardness, such as simple metal cutting, bending and other processes.

In addition, the service life of cemented carbide molds is much longer than that of ordinary molds. Beacuase of its excellent wear resistance and hardness, the service life of cemented carbide molds can reach many times or even dozens of times that of ordinary molds under normal use. This not only reduces the company’s production costs but also improves production efficiency and brings significant economic benefits to the company.

However, the manufacturing cost of cemented carbide molds is relatively high, which is one reason why their practical application is limited. Although the wear resistance and hardness of ordinary molds are not as good as those of cemented carbide molds, their manufacturing costs are lower, and they are suitable for some occasions that do not require high mold performance. Therefore, when selecting mold materials, companies need to make comprehensive considerations and trade-offs based on specific production processes and product requirements.
