Precision Multi-Chamber Aluminum Housing Fluid Connector with 6061-T6 Alloy for Thermal Management Systems via 5-axis CNC Machining

This precision multi-chamber aluminum housing is a core fluid connector customized for new energy vehicle thermal management systems, automotive engine coolant pipelines and industrial hydraulic valve blocks. With an integrated multi-chamber structure, it undertakes the functions of shunting, reversing and transitional connection of coolant/hydraulic oil. It perfectly adapts to the harsh working conditions of high temperature, high pressure and high vibration in automobiles. It is widely used in core fields such as new energy vehicle battery thermal management, engine cooling systems and hydraulic control units, providing accurate and sealed reliable channel structure for fluid systems.

Core Material: 6061-T6 Aluminum Alloy (premium material for automotive thermal management components, adapting to the thermal conductivity and pressure resistance requirements of this part)

Key Performance:

• Tensile strength ≥310MPa, yield strength ≥276MPa, with excellent pressure resistance and creep resistance, can withstand long-term fluid pressure ≥1.5MPa
• Density is only 2.7g/cm³, significantly reducing vehicle weight and improving fuel economy or battery life under the premise of ensuring structural strength
• High thermal conductivity, assisting internal fluid heat dissipation, adapting to the high-temperature environment of the car engine compartment, fully complying with RoHS and REACH environmental protection standards
• Natural corrosion resistance, resistant to coolant and oil corrosion, adapting to complex and changeable automotive outdoor environments

This part adopts 5-axis linkage CNC turn-mill composite machining process, integrally cutting and forming from a solid aluminum bar, ensuring the smoothness and sealing of the multi-chamber flow channel.

• Core processes: precision turning of multi-layer sealing spigots, integrated forming of lateral water nozzles, precision boring of mounting holes, precision milling of internal flow channels
• Auxiliary processes: high-gloss contour chamfering, deburring, surface fine sandblasting treatment, ensuring no burrs or nodules on the inner wall of the flow channel
• Full CNC programming, one-time clamping to complete multi-sided machining, ensuring the consistency of flow channel coaxiality and sealing surface high precision

Machining Accuracy:

• Dimensional tolerance: ±0.01mm, strictly matching the sealing ring and pipeline clearance
• Geometric tolerance: flow channel coaxiality ≤0.015mm, flange surface flatness ≤0.02mm
• Surface roughness: Ra≤1.6μm (inner wall of flow channel Ra≤0.8μm), ensuring fluid flow, reducing resistance and cavitation
• Usage Requirements:
• Adapt to an extreme working environment of -40℃~120℃, can withstand continuous fluid pressure ≥1.5MPa
• No leakage or corrosion during long-term use, ensuring stable circulation of coolant/hydraulic oil
• The mounting surface must be kept clean and flat to ensure the fitting degree and sealing performance of the sealing ring

With heat treatment, adopting solution treatment + artificial aging (T6 state) process.

• Core purpose: eliminate processing internal stress, greatly improve material hardness and structural strength, enhance creep and fatigue resistance, avoid deformation under long-term high pressure/high temperature conditions, and ensure the long-term sealing stability and structural reliability of fluid connection.

Natural color sandblasting treatment, retaining the original metallic texture of aluminum alloy.

• Process advantages: form a dense and uniform surface protective layer, significantly improve corrosion resistance and stone impact resistance, matte texture improves appearance texture, and it is convenient for subsequent painting or electroplating (if required), fully meeting environmental protection requirements.

Implement a full-process closed-loop quality control system, strictly complying with ISO9001 quality standards and automotive parts TS16949 specifications:

• Raw material incoming: spectral material inspection to ensure 6061-T6 alloy composition and mechanical performance meet standards
• Processing process: 100% geometric tolerance inspection, focusing on monitoring flow channel coaxiality and sealing surface accuracy
• Final product inspection: appearance defect inspection, air tightness/water tightness pressure test, full dimensional inspection, traceable inspection report for each batch
• Pre-delivery: cleanliness inspection of the inner cavity to ensure no iron chips and impurities, avoiding flow channel blockage
