Last month, Haina was invited to participate in the High-Pressure Die Casting Forum hosted by ASSAB Steels. As a comprehensive mold manufacturing enterprise, we gathered with numerous experts from the tool steel, die casting, and automotive manufacturing sectors to engage in in-depth discussions on the future of high-pressure die casting technology.

The forum proved immensely valuable, offering us deeper insights into the integrated development of high-pressure die casting technology and the new energy vehicle industry. We have come to appreciate more clearly that the future of high-pressure die casting is closely intertwined with the pulse of the new energy sector, with promising prospects ahead.

New Energy Vehicles: The Core Engine of High-Pressure Die Casting

A recurring consensus at the forum was that new energy vehicles represent the single most significant growth opportunity for the die casting industry today. Lightweighting is the key to extending range and optimizing performance, and high-pressure die casting, with its ability to efficiently produce lightweight, high-strength complex components, aligns perfectly with this requirement. From battery pack housings and motor casings to various body structural parts, the application of high-pressure die castings is expanding rapidly.

In particular, the rise of Giga-casting technology is profoundly reshaping the industry landscape. It consolidates dozens or even hundreds of components—previously produced through stamping and welding—into a single cast using ultra-large die casting machines. This dramatically simplifies production processes, reduces costs, and lowers vehicle body weight. We are witnessing a shift from Tesla's pioneering efforts to active experimentation by companies like China's Dongfeng Motor, where 10,000-tonne class die casting machines are now in operation, capable of producing single components in a cycle time of less than two minutes.

Haina's Perspective: Opportunities at the Technological Intersection

As a player deeply engaged in the die casting mold sector, Haina has developed a unique understanding and perspective on this trend.

First, molds are the core of the die casting process and a key pain point. During the forum, experts delved into persistent challenges in high-pressure die casting, such as "early heat cracking" and "thermal fatigue." This reaffirmed our conviction that mold quality directly determines casting yield and production efficiency. Haina's sustained investment in tool steel selection, heat treatment processes, and cooling system design is aimed at helping our customers solve these core problems, thereby extending mold life and improving casting quality.

Second, Giga-casting imposes higher demands on molds. The proliferation of Giga-casting technology has triggered a surge in demand for ultra-large, highly complex, and long-life molds. This raises the bar for mold manufacturers in terms of design capabilities, machining precision, and manufacturing expertise. Haina is actively responding to this trend by enhancing its comprehensive service capabilities in the large and complex die casting mold segment.

Third, the demands of new energy vehicle customers are driving us to improve. The stringent requirements of NEV customers for casting precision, density, and consistency are, in turn, pushing us to continuously refine our mold design approaches and machining processes. Every challenge presents an opportunity for technological advancement.

Moving Forward Together

High-pressure die casting technology is transitioning from a "cutting-edge technology" to a "mainstream application," and the robust growth of the new energy industry is providing it with a vast stage. As a mold manufacturer, Haina is honored to participate in such industry exchanges, both to gain insights and to contribute our own perspectives.

Looking ahead, we will continue to focus on the die casting mold sector, keeping pace with the development trends of Giga-casting and new energy vehicles. Through higher-quality mold products and services, we aim to help our customers seize opportunities in this transformative era. We firmly believe that only through collaborative innovation across the entire industry chain can we collectively drive a more efficient and greener future.
