Effect of surface treatment technology on the durability of the bent die

In the field of metalworking, the durability of the bent overmold is one of the key factors to ensure production efficiency and product quality. Surface treatment technology plays a crucial role in improving the durability of the bends. For example, the hardness and wear resistance of the mold surface can be significantly improved by employing heat treatment processes such as carburization or nitriding. According to the study, the surface hardness of the mold with proper heat treatment can reach 60-62 HRC, which is about 20% higher than the untreated mold surface hardness. This increase in hardness is directly related to the service life of the die, because harder surfaces are resistant to friction and wear caused during metalworking.

In addition, surface coating techniques such as physical vapor deposition (PVD) and chemical vapor deposition (CVD) provide additional protection for the bent mold. These coatings can reduce the friction between the mold and the workpiece, reduce the wear, and prevent the common adhesion phenomenon in metalworking. For example, a diamond carbon coating (DLC) bent overmold improves the wear resistance to more than 10 times that of ordinary steel. In practical applications, this coating technology allows molds to maintain precision and performance for longer periods when processing high-hardness materials, such as titanium alloy or stainless steel.

For the analytical models, we can refer to the famous Arrhenius equation (Arrhenius equation), which describes the effect of temperature on the chemical reaction rate. By applying this principle to the surface treatment of the bent mold, we can conclude that the wear rate can be reduced by reducing the reactivity of the mold surface. Therefore, the surface treatment technology not only improves the physical characteristics of the mold, but also enhances its durability through the chemical stability.

As Henry Ford says: ” Quality is the only lead that will not be overtaken by competitors.”In the design and manufacturing of the bending mold, through the use of advanced surface treatment technology, to ensure the high quality and long life of the mold, so as to maintain a leading advantage in the fierce market competition.https://www.mhtcnc.com/product/bending-mold/
