How Weijing 3D Guarantees Dimensional Accuracy for AITO V9 from Prototyping to Mass Production
Pre-sales recently kicked off for the Luxeed V9, the first full-scene intelligent flagship MPV under HIMA (Harmony Intelligent Mobility Alliance). It secured over 22,500 orders within 72 hours, with market enthusiasm continuing to surge.
Behind its outstanding market performance lies the ultra-rigorous standards Luxeed has set for the body structural safety of the V9.
Notably, the rear floor of the Luxeed V9 integrates up to 78 separate components in traditional structures into a single integrated piece, cutting component weight by more than 15%. Nearly a hundred welding points are eliminated, drastically boosting the overall rigidity and load transfer continuity of the rear structure. Cabin deformation during collisions is significantly reduced, delivering identical safety protection for third-row passengers as those in the front seats.
Lighter body, stronger protection — the Luxeed V9 achieves dual advancements in lightweight design and passive safety.
Yet there is an unavoidable hurdle for die castings moving from prototyping to mass production: dimensional accuracy and its verification and control.
The rear floor features a sophisticated structure with drastic wall thickness variations. During the filling and solidification of aluminum alloy, sound internal quality is mandatory, while precise external dimensions also determine seamless fitting with the vehicle body.
Castings boast denser texture, thinner walls and more integrated structures, yet come with tighter tolerances, hard-to-reach distal sections and complex features difficult to fully inspect. Unidentified dimensional deviations passed on to subsequent processes may trigger assembly interference and inconsistent gaps, compromising overall vehicle quality and safety performance.
Therefore, adopting high-precision full-dimensional measurement solutions to rapidly verify process feasibility and shorten iteration cycles during prototyping, as well as sustain consistent dimensional performance post mass production, constitutes a critical link in guaranteeing the quality of Luxeed V9 rear floor panels.
The integrated automated 3D measurement solution for one-piece die-cast rear floors from Weijing 3D has been deeply integrated into the prototyping and production system of Luxeed V9 rear floor panels.
High Precision
This solution is equipped with the PowerScan 5M330 Pro blue light probe, delivering a single-shot measurement accuracy of 0.02 mm. It captures millions of point clouds in one scan to cover all features including positional tolerance of machined holes, profile tolerance of blank surfaces and wall thickness uniformity, enabling efficient full-dimensional inspection with high precision.
High Efficiency
No target dots or scanning spray required; one-click startup supported. Equipped with a servo-driven rotary table and multi-angle trajectory planning for robotic arms, enabling zero blind zones at the bottom. With 10G fiber optic transmission and GPU parallel computing, single-shot measurement takes less than 0.2 seconds, allowing rapid full inspection of batches.
Data Visualization
Visual measurement reports are automatically generated upon scan completion. Contour color difference diagrams, wall thickness analysis and dimensional feature evaluation enable process engineers to quickly judge filling uniformity and dimensional stability, realize feedforward troubleshooting, and drive iteration of die-casting parameters, thereby greatly shortening prototyping cycles.
The implementation of this verification system is backed by Weijing 3D’s technical expertise accumulated in automated 3D measurement.
Focused on independent R&D and application of high-precision blue-light 3D measurement technology, Weijing 3D stands as a key domestic player in automated 3D measurement for integrated die casting. Its core product lineup includes blue-light 3D scanners, automated measurement stations and supporting measurement software, serving numerous leading vehicle manufacturers and component suppliers.
Luxeed V9 has completed full verification from scratch. Weijing 3D’s blue-light measurement solution will shift from validation to full-scale mass production quality control, continuously performing full-dimensional inspection and providing traceable dimensional data foundation to underpin Luxeed V9’s safety commitments.
