Behind this impressive market performance, the Luxeed V9 has set rigorous standards for body structure safety.

What is particularly noteworthy is that its rear vehicle body floor adopts the industry‑leading integrated die‑casting process, consolidating as many as 78 individual parts of the conventional rear body structure into a single cast component, achieving a weight reduction of more than 15%.

More importantly, this integrated design eliminates nearly a hundred weld spots at the structural root, completely avoiding the structural consistency variations that may arise from welding quality fluctuations. It significantly improves the overall rigidity and continuous load‑transfer capability of the rear body structure, providing third‑row occupants with collision protection comparable to that of the front row, thereby safeguarding cabin safety.

However, the higher the degree of integration of an integrated die‑casting, the lower its tolerance for internal defects.

The rear floor die‑casting has a complex geometry and significant wall thickness variations. During the filling and solidification of the molten aluminum alloy, internal defects such as gas porosity and shrinkage porosity are inherent challenges of the casting process.

If these defects are not effectively identified and allowed to proceed to downstream processes, they may affect the mechanical properties of the component and pose potential risks to the vehicle's overall safety performance.

Therefore, employing high‑precision X‑ray non‑destructive testing (NDT) is a necessary measure to detect and intercept defects, thereby ensuring outgoing quality.
When planning the production system for the rear floor, the Luxeed V9 set a mandatory requirement from the very beginning: every single rear floor must pass high‑precision X‑ray NDT online full inspection before moving to the next process step.

This represents a leap in quality control from statistical sampling to deterministic full inspection, and a fundamental shift in ensuring the safety quality of integrated die‑cast parts.
On the Luxeed V9 rear floor production line, UNICOM’s large‑scale integrated die‑casting X‑ray intelligent inspection equipment has been deeply integrated to achieve online 100% inspection.

Leveraging UNICOM’s self‑developed advanced X‑ray NDT technology and AI‑based automatic defect recognition (ADR) algorithms, this equipment can efficiently and accurately detect internal defects in the rear floor. Whether tiny gas pores or hidden shrinkage cavities, they can be precisely identified and judged, ensuring zero defect leakage.

At the same time, inspection results are uploaded in real time to the production control system, forming a traceable closed‑loop quality data chain. This provides a solid data foundation for the Luxeed V9’s overall safety promise.
The implementation of this quality control system relies on UNICOM’s profound technological accumulation in the field of industrial X‑ray intelligent inspection.

As a leading enterprise in China’s industrial X‑ray intelligent inspection industry, UNICOM Technology (Stock Code: 688531) is a national “Little Giant” specialized and sophisticated enterprise, a manufacturing single‑item champion enterprise, and a listed company on the Science and Technology Innovation Board (STAR Market). It focuses on providing industrial X‑ray inspection equipment and core components for high‑end manufacturing.

After ten years of technical breakthroughs, UNICOM successfully developed and industrialized its own microfocus X‑ray source, breaking the long‑standing monopoly of the United States and Japan, filling a domestic gap, and solving the “bottleneck” problem of core components in industrial inspection.
Looking ahead, as the application of electromagnetic thermal control die‑casting technology continues to deepen, internal defects in castings will be further and effectively controlled at the source.

This is not only the Luxeed V9’s technical commitment to the safety of third‑row MPV occupants, but also a true reflection of Harmony Intelligent Mobility’s continuous effort to solidify its technological moat in the high‑end manufacturing sector.

About CHINA DIECASTING & CHINA NONFERROUS 2026

UNICOM will exhibit at Asia's largest specialized die-casting and non-ferrous exhibition—CHINA DIECASTING & CHINA NONFERROUS 2026 (Shanghai New International Expo Center, Halls N1-N5) from July 15-17, 2026, at Booth N2C31. Under the theme "Twin Engines: Al & Mg, A Lightweight Future", this edition is expected to span 52,000+ square meters, feature 600+ exhibitors, and attract 28,000 professional visitors.

The global die casting industry is undergoing several major transformations: the scaling and industrialization of large megacasting, breakthroughs in rheocasting technologies, and the expanding potential of die casting beyond new energy vehicles - into fields such as Two-Wheelers (Emerging Trend: Replacing Aluminum with Magnesium), humanoid robot, energy storage, photovoltaics, and aerospace. As a barometer of the Asian market, the event will showcase technological advancements, product applications, and integrated solutions across these three key tracks.
