Mingmei only uses international first-line brand mold steel such as ASSAB, LKM, Buderus, etc. All steel must undergo a triple inspection of hardness testing, material verification, and size verification before being stored to prevent unqualified materials from entering the process. Standard parts, hot runners, and accessories are all sourced from well-known brands in the industry, ensuring mold strength, wear resistance, and service life from the source, laying a solid foundation for long-term stable mass production.
