Drawing Design & Confirm
Die Casting Mold Design Drawing Requirements and Confirmation Specifications
(Applies to automotive/3C/aerospace die casting molds)
I. Core Design Specifications
Digital Design Requirements
· Software:
· Mandatory use of AI-optimized CAD tools (e.g., AutoCAD 2025/Autodesk Fusion).
· File formats: STEP/IGES (compatible with digital twin systems).
· Tolerances:
· Critical dimensions: ±0.02mm (red-label zones).
· General dimensions: ±0.05mm (blue-label zones).
Structural Design
· Mold Cavity & Runners:
· Runner cross-sectional area deviation ≤1.5% (AI flow simulation report required).
· Cooling channel spacing ≤30mm (validated via thermal imaging).
· Ejection System:
· Ejector pin diameter ≥Φ3mm (fatigue life ≥500,000 cycles).
2025 Mandatory Additions
· Smart Integration:
· IoT sensor ports (temperature/pressure/vibration) must be embedded in mold design.
· QR code traceability labels (material batch/version/carbon footprint).
· Eco-Compliance:
· Priority for low-carbon mold steel (emissions ≤1.8kgCO₂/kg).
· Scrap mold recycling rate ≥95% (recycling agreement required).
Signatures & Archiving
E-Signatures:
· Digital signatures from designer/reviewer/approver (eIDAS 2.0 compliant).
Cloud Storage:
· Saved to enterprise blockchain (1 main chain + 2 backups).
· Encryption: AES-256 + quantum-safe protocols.
Non-Compliance Penalties
-Design permissions frozen if AI review fails.
-Mould steel without recycling mark is prohibited (fines refer to EU 2025/EMD regulations)

Review Focus
· Material Compatibility: Thermal expansion coefficient difference ≤5% between mold steel and casting alloy.
· Sustainability Metrics:
· Mold lifespan ≥200,000 cycles (CAE fatigue analysis required).
· Repairability score ≥90% (per ISO 14006:2025).
