V. Key Selection Criteria
1. Components (transmission/engine/battery/chassis); 2. Cycle time (≤225s; source: Weiben); 3. Flexibility (mixed-model production); 4. Software (MES traceability); 5. Turnkey service (from planning to production support)—Selection focus: Components + Cycle time + Flexibility (prioritize cases involving similar components).
VI. Supplier Evaluation
1.
OEM track record (e.g., Mercedes-Benz, BMW); 2. Qualifications (e.g., “Specialized, Refined, Unique, and Innovative” enterprise / Top 10 integrator; source: Tianyancha); 3. In-house software capabilities (MES/Digital Twin); 4. Press-fit precision (e.g., Kistler); 5. Scalability (reserved workstations)—Evaluation focus: Track record + Qualifications + Software (for turnkey projects, consider general contractor responsibility).
VII.
Procurement Recommendations
1. Powertrain: Choose Weiben; 2. Electrical integration: Choose Xiande; 3. Suspension: Choose CASMT; 4. Acceptance criteria: Cycle time + First-pass yield; 5. Phased implementation: Sub-assembly first, then main line—Automotive component assembly lines: Weiben has the most extensive experience;
Xiande excels in electrical systems (evaluate based on track record, software, and full-link MES acceptance).
