FAQ
1. What are the key advantages of aluminum housings over plastic or brass?
Superior Strength: Withstands higher pressures (up to 30 bar burst) vs. plastic (typically <10 bar)
Lightweight: 60% lighter than brass with better corrosion resistance
Thermal Stability: Maintains dimensional integrity across boiler operating temperatures (-40°C to +150°C)
2. How do I choose between cast and forged versions?
Factor | Cast Housing (A380) | Forged Housing (6061/7075) |
---|---|---|
Best For | Complex shapes/thin walls | High-stress areas |
Cost | Lower (high volume) | Higher (premium strength) |
Lead Time | Faster (ready molds) | Longer (custom dies) |
Pressure Rating | 10 bar design | 15 bar design |
5. How do you prevent leaks in cast versions?
Process: Vacuum-assisted high-pressure die casting
Inspection: 100% X-ray scanning for porosity
Sealing: CNC-machined gasket grooves (±0.03mm flatness)
6. What surface treatments extend product life?
Standard: Chromate conversion (Alodine 1200)
Premium: Hard anodizing (50μm, MIL-A-8625)
Special: PTFE coating for sticky environments
7. What’s your MOQ and lead time?
Prototypes: 5 pcs (3 weeks)
Production: 500 pcs (6-8 weeks)
Expedited: +25% cost (30% time reduction)
8. Do you provide pressure testing reports?
Yes, each batch includes:
Helium leak test data (<1×10⁻⁶ mbar·L/s)
Burst pressure validation video (on request)
Material certs (EN 10204 3.1)
