Trusted by Leading Businesses

Engineering Director, Robotics Company

We had a multi-axis robotic joint housing with tight spatial constraints and conflicting load paths. Their mechanical team restructured the entire load-bearing architecture, reducing part count from 14 to 6 while exceeding the original stiffness target by 18%. The DFM review alone saved us three tool modification cycles.

VP of Operations, Industrial Equipment Manufacturer

Their cost engineering approach changed how we think about mechanical design. By identifying the CNC-to-die-cast transition threshold and redesigning our mounting bracket family around shared tooling, they cut our per-unit cost by 32% across a 50K production run — without any compromise in structural performance.

CTO, Smart Building Solutions Provider

Most mechanical designers work in isolation. This team embedded directly with our electrical and firmware engineers from day one. Thermal management, cable routing, and sensor mounting were solved as integrated problems — not bolted on after the fact. Our first prototype passed all environmental tests with zero mechanical redesigns.

FAQ for Mechanical Design

Q.
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)
2. Non-critical: IT12 tolerance class
3. Deliverable：Production-Ready Design Package with mold flow analysis reports.
Q.
How is structural strength maintained in lightweight designs?
Weight-performance optimization through:

Material Science
1. Magnesium alloys (35% lighter than aluminum)
2. 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.
Q.
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.
Q.
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.
