MEGA Tech invites readers to explore some of the key seminar highlights and innovative technologies presented during the event, reflecting the direction and future of the modern die-casting industry.
Indonesia Die Casting Industry: Ecosystem and Collaboration Opportunities
Presented by Mr. Toto Suharto, Head of Automotive at The Institution of Engineering Indonesia (PII) and Country Manager of RMA Indonesia, the seminar highlighted the rapid growth of Indonesia’s electric vehicle (EV) market and the significant opportunities it is creating for the die-casting and aluminum components industries across the region. In 2025, EV adoption in Indonesia reached 13%, while vehicle sales increased by 58% compared to the previous year.

A key driving force behind this growth is not only rising consumer demand, but also Indonesia’s TKDN (Local Content Requirement) policy, which requires EV manufacturers to progressively increase the proportion of locally produced components in order to qualify for tax incentives and government support.
Under the current roadmap, the local content requirement will increase from 40% today to 60% during 2027–2029, and eventually reach 80% by 2030. As a result, automotive manufacturers are accelerating the development of domestic supply chains. One critical challenge is that batteries account for approximately 35–40% of an EV’s total value. Achieving an 80% TKDN target will therefore be nearly impossible without local production of key components such as battery housings, motor housings, and structural castings — all of which are core products of the die-casting industry.
At the same time, aluminum consumption in EVs continues to rise significantly, increasing from 205 kilograms per vehicle in 2022 to an estimated 256 kilograms per vehicle by 2030. This trend reflects the growing demand for lightweight aluminum cast components alongside the expansion of the EV market. Another important development is the expansion of EV manufacturing facilities by major automakers such as BYD and VinFast into the Subang area, while most existing foundry clusters remain concentrated in Bekasi, more than 100 kilometers away. This supply chain gap is creating new investment opportunities for die-casting manufacturers to establish operations closer to emerging automotive production hubs.
Based on these market trends, experts identified six high-potential business segments: HPDC production lines for EVs, aluminum alloy recycling and production, mold and tooling centers, 2,000–6,000 ton gigacasting systems, technical workforce development, and Industry 4.0/MES solutions.
In conclusion, the rapid growth of the EV industry, combined with the implementation of TKDN regulations, is transforming die casting from a supporting industry into a strategic pillar of Indonesia’s EV supply chain. Companies entering the market during the 2026–2030 period are expected to have strong opportunities to become part of the supply networks of major automotive manufacturers expanding their investments in Indonesia.
Lightweight Aluminum Casting Products : Driving the Future of Sustainable Electric Mobility
Presented by Mr. Thanakorn Thangwanichkapong, Director of Asia Operations at Maxion Wheels and Vice Chairman of the Foundry Industry Club under The Federation of Thai Industries (FTI), the seminar highlighted one of the automotive industry’s most critical challenges in the EV era: how to extend driving range, reduce energy consumption, and control production costs simultaneously.
In the past, increasing battery size was considered the primary solution for extending EV driving range. However, larger batteries also add significant weight, resulting in higher energy consumption, increased production costs, and limitations in overall vehicle efficiency. As competition in the EV market intensifies, global automakers are now shifting toward a more effective approach — lightweight vehicle design.

Industry data shows that reducing vehicle weight by just 10% can improve driving range by approximately 6–8% without increasing battery capacity. As a result, “Lightweight” has become one of the most important strategic directions for EV manufacturers worldwide. Among lightweight materials, aluminum has emerged as the leading choice, currently accounting for approximately 45% of the lightweight automotive materials market. Aluminum offers a weight reduction of 40–60% compared with steel, while still maintaining the strength and safety required for modern vehicle applications.
Several leading automotive manufacturers have already demonstrated the effectiveness of this approach. Tesla Model S, for example, utilizes aluminum extensively in its main structure, reducing vehicle weight by approximately 23%. Meanwhile, the Audi e-tron GT incorporates more than 60% aluminum in its body structure to improve driving efficiency and range.Beyond performance advantages, aluminum also supports sustainability goals. Recycled aluminum can reduce energy consumption by up to 95% compared with primary aluminum production, enabling manufacturers to lower carbon emissions and comply with increasingly stringent global ESG standards.
Driven by these trends, the global lightweight materials market for EVs is expected to continue expanding, growing from approximately USD 100.3 billion in 2025 to more than USD 115.8 billion by 2030. Looking ahead, competition in the EV industry may no longer be defined solely by battery size, but by which manufacturers can design vehicles that are lighter, stronger, and more sustainable.
Lightweight technology is no longer simply a material trend — it is becoming a core foundation of future mobility development. By improving driving range, reducing production costs, lowering energy consumption, and supporting global Net Zero targets, lightweight solutions are reshaping the future of the automotive industry. For component manufacturers and supply chain operators, investment in aluminum casting, digital manufacturing, automation, and advanced material innovation is no longer just a business opportunity, but a critical factor in remaining competitive in the rapidly evolving New Mobility era.
Beyond the intensive knowledge-sharing sessions and advanced technologies presented during the seminars, another key highlight of the event was the perspectives shared by leading exhibitors and industry players. Their insights reflected emerging business opportunities, the growth direction of the die-casting industry, and the accelerating transition toward the EV era across the region.
MEGA Tech invites readers to explore the opinions and experiences of selected exhibitors who shared their views on the future of manufacturing and industrial development in Southeast Asia.
