1. Requirement Co-design

DFM Drives Zero-Defect Starting Point
Engineers provide die-casting-specific DFM solutions through 1v1 3D drawing analysis:
Optimize draft angles/wall thickness/ribs —— Reduce shrinkage risk by 30%
Intelligent simulation of metal flow —— Predict porosity location, extend mold life by 50%

2. Intelligent Die-Casting Programming

Dynamic Parameters for Precise Form Control
Cloud-based die-casting platform calculates optimal process chain in real-time:
Three-stage injection control: Slow-speed 0.3m/s degassing → High-speed 6m/s filling → Intensification 100MPa feeding
Precise mold temperature zoning ±5℃ —— Eliminate flow marks/cold shuts

3. Ultra-Clean Preprocessing

Dual Safeguards for Quality Assurance
Alloy melt purification:
Argon degassing + density testing —— Hydrogen content ≤0.1ml/100g
Intelligent mold maintenance:
Automated nano-coating spray → Laser-calibrated mold temperature → Mold clamping gap <0.03mm

FAQs of Pressure Die Casting
  • Do you have a minimum order quantity?
    加 Created with Sketch.
    形状 Created with Sketch.
    NO! – No minimum quantity! We provides rapid prototypes and short to medium-run production machining services.
  • What general tolerances can you achieve?
    加 Created with Sketch.
    形状 Created with Sketch.
    General CNC Machining Tolerances on metal to +/- 0.005" (+/- 0.127 mm) following ISO 2768 unless otherwise specified. CNC Plastics and composites will be +/- 0.010”(+/- 0.254 mm).
  • What type of design files do you accept for quoting?
    加 Created with Sketch.
    形状 Created with Sketch.
    For the 3D drawing, we would prefer STEP, IGES, or X_T format. For the 2D drawing, we would prefer PDF format there are tolerances with the dimensions if possible.
  • What shall we do if we don't have drawings?
    加 Created with Sketch.
    形状 Created with Sketch.
    Please send your sample to our factory, then we can copy and provide you better solutions. lf send us pictures or drafts with dimensions(Length,Height, Width), CAD or 3D file will be made for you.
  • What precision tolerances can you achieve?
