In modern manufacturing, precision molds play a vital role. Their performance and precision depend largely on the materials selected. The following is a detailed introduction to the main materials of precision molds.
Cr12MoV is a commonly used cold working die steel material. It has high hardenability, high hardness and good wear resistance. After proper heat treatment, Cr12MoV can obtain high hardness and high wear resistance, which can meet the use requirements of precision molds under complex working conditions. This material performs well in the manufacture of precision molds that are subject to large impact loads, such as some stamping molds and shearing molds.
SKD11 is also a popular cold working die steel. Its high carbon content makes it extremely hard and wear-resistant. At the same time, SKD11 has relatively good toughness and can resist a certain degree of impact and deformation. In the manufacture of high-precision and high-life precision molds, SKD11 has a wide range of applications, such as mobile phone shell stamping molds and other electronic product manufacturing fields.
P20 steel is a leader in hot working die steel. It has good processing and polishing properties, high hardness and good stability after heat treatment. P20 steel is often used to manufacture hot working molds such as injection molds and die-casting molds. Its stable performance enables the mold to maintain good precision and service life under high temperature and high pressure working environments.
In addition, H13 steel also has an important position in the field of precision molds. It has good toughness and thermal fatigue resistance, and can adapt to frequent heating and cooling processes. When manufacturing hot working molds such as die-casting molds and extrusion molds, H13 steel can effectively resist thermal wear and thermal cracks.
Precision molds of different materials play their respective advantages in different processing scenarios. Understanding the characteristics and application scope of these main materials will help the manufacturing industry make more reasonable choices in the mold design and manufacturing process, thereby improving product quality and production efficiency.
