Wuxi, China, July 22, 2025 — Mingteng International Corporation Inc. (the “Company” or “Mingteng International”) (Nasdaq: MTEN), a developer and supplier of automotive molds in China, has announced that its wholly-owned subsidiary, Wuxi Mingteng Mould Technology Co., Ltd. (“Wuxi Mingteng”), formalized a technology development entrustment agreement (the “Entrustment Agreement”) with Jilin University (“JLU”). This partnership, effective from December 26, 2024, to December 26, 2027, aims to collaboratively develop a new hot-work die steel designed for die-casting molds. This strategic move is intended to elevate the Company’s technical expertise to match global industry leaders and capitalize on the increasing demand for high-quality aluminum alloy die-castings.

Under the terms of the Entrustment Agreement, Wuxi Mingteng will commission JLU and furnish necessary background technical data for the joint development of the innovative hot-work die steel for die-casting molds. In return, Wuxi Mingteng will be granted royalty-free usage rights for any patents generated from this development project. Upon the project’s three-year completion, the Company anticipates the new material will enable an average die-casting lifespan exceeding 80,000 cycles, demonstrate significantly improved thermal fatigue performance compared to imported 8407 die steel, and yield a 40% reduction in overall material costs. Wuxi Mingteng has already manufactured molds using the initial batch of trial die steel materials from the project, delivering them to selected customers for preliminary application testing. Based on early feedback from these customers, the materials have performed as expected. Wuxi Mingteng plans to proceed with further small-batch validation to continuously assess consistency and suitability for commercial deployment.

JLU is a highly regarded public university situated in Changchun, Jilin, China. It holds distinction as one of the universities supported by China’s Project 211, Project 985, and the Double First-Class Initiative, all of which are national strategies supported by the Chinese central government to bolster the global competitiveness of Chinese higher education institutions.

Mr. Yingkai Xu, Chairman and Chief Executive Officer of Mingteng International, remarked, “The rapid advancements in new energy vehicles, electronics, aerospace, and other sectors have fueled a surge in demand for high-quality aluminum alloy die-castings, particularly those emphasizing lightweight properties. This trend is propelling the continuous expansion of the die-casting mold material market. To seize this expanding market segment while addressing cost pressures from both the market and customers, we have chosen to bolster our technical capabilities through this collaboration with JLU. Our objective is to achieve the technical proficiency of leading international peers such as ASSAB, Hitachi, and Daido, delivering high performance and quality at a cost-effective level. By merging JLU’s robust R&D capabilities with our extensive manufacturing and market experience, we foresee that the new hot-work die steel will rival the performance of high-end international brands.”

Mr. Xu further stated, “Looking ahead, we believe that the cost advantage offered by this new material will serve as a key growth catalyst for Mingteng International. Although precise sales data for die-casting die steel in China is not readily available, the widespread industrial demand for aluminum alloy die-castings—which are intricately linked to die-casting molds—will underpin our long-term growth, generating a strong revenue stream and delivering substantial value to both our Company and our shareholders.”
