Precision Housing Cast / Forged Aluminum Parts For Wall Mounted Boiler Pressure

Product Specification

Precision Cast/Forged Aluminum Housing Components for Wall-Mounted Boiler Pressure Switches

Product Overview

Our precision cast and forged aluminum housing components are engineered to meet the stringent demands of wall-mounted boiler pressure switches, ensuring exceptional durability, thermal stability, and airtight sealing performance. These critical safety components are manufactured using advanced casting (die-cast/sand-cast) and forging processes, making them ideal for OEM boiler manufacturers and replacement part suppliers who require long-lasting, corrosion-resistant pressure switch housings.

Key Features & Benefits

✅ Superior Material Performance

• Made from A380, ADC12 (die-cast) or 6061/7075 (forged) aluminum alloys for optimal strength-to-weight ratio
• 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
• Integrated mounting features (threads, flanges, gasket grooves) for easy installation

✅ Reliability & Safety

• Pressure-tested up to 2x working pressure (typically 0.5-5 bar range)
• Zero porosity in critical sealing areas (X-ray inspected for cast versions)
• EMI/RFI shielding options available for electronic switches

✅ Customization Options

• Hybrid designs combining cast body with forged high-stress components
• Surface treatments: Anodizing (Type II/III), powder coating, e-coating
• Marking/labeling: Laser engraving, embossing for traceability

Applications

• Gas boilers (condensing/non-condensing)

• Heat pump pressure controls

• Hydronic system safety switches

• Commercial boiler monitoring systems

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?

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)
