Mingteng International's Subsidiary and Jilin University Collaborate to Develop Hot-Work Die Steel for Die-Casting Molds Targeting 80,000-Cycle Lifespan and 40% Cost Reduction

Wuxi, China, July 22, 2025 (GLOBE NEWSWIRE) -- Mingteng International Corporation Inc. (the "Company" or "Mingteng International") (NASDAQ:MTEN), an automotive mold developer and supplier in China, announced that its wholly-owned subsidiary, Wuxi Mingteng Mould Technology Co., Ltd. ("Wuxi Mingteng"), has signed a technology development entrustment agreement (the "Entrustment Agreement") with Jilin University ("JLU") to collaborate on the development of a new hot-work die steel for die-casting molds, effective from December 26, 2024 to December 26, 2027. This strategic initiative aims to enhance the Company's technical capabilities to align with international industry leaders while tapping into the growing demand for high-quality aluminum alloy die-castings.

Following the Entrustment Agreement, Wuxi Mingteng has agreed to commission JLU and provide background technical data to jointly develop the new hot-work die steel for die-casting molds. In return, Wuxi Mingteng will be granted free usage right for any patents resulting from the development project. Upon completion of the three-year development project, the Company expects an average die-casting lifespan exceeding 80,000 cycles, significantly better thermal fatigue performance compared to imported 8407 die steel, and a 40% reduction in overall material costs. Wuxi Mingteng has also completed fabrication of molds using the first batch of trial die steel materials under the development project. These molds have been delivered to selected customers for preliminary application testing. Based on initial customer observations, the materials have performed in accordance with expectations. Wuxi Mingtengy intends to proceed with further small-batch validation to continue assessing consistency and suitability for commercial use.

JLU is a prestigious public university, located in Changchun, Jilin, China. It is among the select universities supported under China's Project 211, Project 985, and the Double First-Class Initiative, all of which are national strategies backed by the Chinese central government to enhance the global competitiveness of Chinese higher education institutions.

Mr. Yingkai Xu, Chairman and Chief Executive Officer of Mingteng International, commented, "With the rapid development of new energy vehicles, electronics, aerospace, and other industries, the demand for high-quality aluminum alloy die-castings—especially those prioritizing lightweight materials—has been surging. This trend is driving the continuous expansion of the die-casting mold material market. To capitalize on this growing market segment while navigating cost pressures from both the market and customers, we have decided to strengthen our technical capabilities through collaboration with JLU. Our goal is to match the technical expertise of leading international peers such as ASSAB, Hitachi, and Daido, achieving high performance and quality at a cost-effective level. By combining JLU's strong R&D capabilities with our extensive manufacturing and market experience, we anticipate that the new hot-work die steel will match the performance of high-end international brands."

Mr. Xu continued, "Looking ahead, we believe that the cost advantage of this new material will make it a key growth driver for Mingteng International. While there is no precise sales data for die-casting die steel in China, the widespread industrial demand for aluminum alloy die-castings—closely linked to die-casting molds—will support our long-term growth, generating a strong revenue stream and delivering substantial value to our Company and shareholders."
