Mechanical design is the core of product functionality and reliability.
Through precise engineering and innovative structural solutions, we transform concepts into manufacturable, durable products that perform flawlessly in harsh environments – all while optimizing costs and production efficiency.

How do you validate the reliability of mechanical designs?
Our three-tier verification system ensures robustness across the product lifecycle:
Simulation Analysis
① Static/dynamic load analysis (ANSYS Stress/Strain Mapping)
① Fatigue life prediction (10⁶ cycles baseline)
Lab Testing
① Environmental: -40°C~150°C thermal cycling / 500hr salt spray (ASTM B117)
② Mechanical: 20G shock (MIL-STD-810) / 20-2000Hz random vibration (IEC 60068-2-64)
Scenario Validation
200-hour endurance testing (e.g., 200K motion cycles for medical devices)
Case Study: Surgical robot arm passed ISO 13485 reliability certification with 0 field failures in 3 years.
How do you ensure manufacturability (DFM) in mechanical designs?
Three-pillar DFM framework:
Mold-Friendly Design
Draft angles ≥1° / Undercut avoidance / Core slider optimization
Process Compliance
Die-cast wall thickness: 2.5-4mm / Sheet metal bend radius ≥1.5T
Tolerance Strategy
① Critical dimensions: GD&T positioning ±0.05mm (ASME Y14.5)
① Non-critical: IT12 tolerance class
Deliverable：Production-Ready Design Package with mold flow analysis reports.
How is structural strength maintained in lightweight designs?
Weight-performance optimization through:
Material Science
① Magnesium alloys (35% lighter than aluminum)
① Carbon fiber composites (5x specific strength of steel)
Topology Optimization
AI-driven lattice structures (42% weight reduction in drone arms)
Advanced Manufacturing
SLM 3D printing for load-bearing monolithic parts
Result：AGV chassis achieved 30% weight reduction while passing ISO 12100 safety validation.
How do you control costs without compromising quality?
Four-dimensional cost engineering:
Design: 80% modular components + 20% custom parts
Process: Switch CNC→die-casting at 10K unit thresholds
Supply Chain: Approved alternate vendors for non-critical items (15-25% cost reduction)
Serviceability: Tool-less disassembly design (50% faster maintenance)
Case Study: Industrial conveyor frame costs reduced by 28% via standardized connectors.
How are assembly conflicts prevented in complex mechanisms?
Three-layer error-proofing:
Digital Twin Validation：DELMIA assembly simulation (detect spatial clashes)
Tolerance Stack Analysis：0.2mm clearance buffer for dynamic interfaces
Poka-Yoke Design：QR code-guided assembly sequences
Case Study : 99.6% first-pass yield achieved in multisensor industrial valve assembly.
