Product Description
Precision Aluminum Housing Components for Boiler Pressure Switches
Product Overview
Our precision cast and forged aluminum housing components are engineered for wall-mounted boiler pressure switches, delivering exceptional durability, thermal stability, and airtight sealing performance. Manufactured using advanced casting and forging processes, these critical safety components serve OEM boiler manufacturers and replacement part suppliers requiring long-lasting, corrosion-resistant pressure switch housings.
Key Features & Benefits
- Superior Material Performance: A380, ADC12 (die-cast) or 6061/7075 (forged) aluminum alloys for optimal strength-to-weight ratio with excellent corrosion resistance against steam, condensate, and combustion byproducts. Stable performance across -30°C to +150°C operating temperatures.
- Precision Engineering: Tight tolerances (±0.1mm casting / ±0.05mm forging) ensure perfect switch diaphragm sealing. Smooth internal surfaces (Ra 1.6μm) prevent air turbulence affecting pressure readings with integrated mounting features.
- Reliability & Safety: Pressure-tested up to 2x working pressure (0.5-5 bar range). Zero porosity in critical sealing areas with EMI/RFI shielding options available.
- Customization Options: Hybrid designs combining cast body with forged high-stress components. Surface treatments include anodizing, powder coating, e-coating with laser engraving and embossing for traceability.
Applications
- Gas boilers (condensing/non-condensing)
- Heat pump pressure controls
- Hydronic system safety switches
- Commercial boiler monitoring systems

Frequently Asked Questions
What are the key advantages of aluminum housings over plastic or brass?
Superior strength withstands higher pressures up to 30 bar burst versus plastic (typically
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 |
How do you prevent leaks in cast versions?
Vacuum-assisted high-pressure die casting process with 100% X-ray scanning for porosity inspection. CNC-machined gasket grooves maintain ±0.03mm flatness for optimal sealing.
What surface treatments extend product life?
Standard chromate conversion (Alodine 1200), premium hard anodizing (50μm, MIL-A-8625), and special PTFE coating for sticky environments.
What's your MOQ and lead time?
Prototypes: 5 pcs (3 weeks). Production: 500 pcs (6-8 weeks). Expedited: +25% cost (30% time reduction).
Do you provide pressure testing reports?
Yes, each batch includes helium leak test data (
