Custom CNC Turn-Mill Aluminum Circular Housing End Cap with Side Threaded Port

This aluminum circular housing end cap is fabricated by CNC turn-mill composite machining. It features deep internal cavity, central through bore, distributed mounting holes and side threaded port. Blue anodized surface provides excellent corrosion resistance and premium appearance, widely used for fluid chambers, pump housings and sensor enclosures.

This circular aluminum end cap is one-piece CNC turn-mill machined from solid aluminum billet. The deep internal cavity and central through bore are finish-bored to tight tolerance, while the side threaded port and flange mounting holes are precisely positioned in the same setup. Single clamping ensures good concentricity between the bore and side port axis.

Chenrong Precision has extensive experience machining aluminum housing components with cross-port features. The blue anodized coating not only enhances visual appeal but also improves surface hardness and corrosion resistance. We can customize cavity depth, flange hole layout, side thread specification and anodizing color according to your engineering drawings.

• One-piece turn-mill machining, high concentricity of cavity and side port
• Deep internal cavity with smooth bored surface
• Side threaded port for pipeline connection
• Distributed flange mounting holes for sealed assembly
• Blue anodized finish, corrosion-resistant and decorative

We specialize in turn-mill machining of circular housing and end cap components. Single-setup processing eliminates alignment errors between features. Our QC team inspects cavity diameter, flatness, thread quality and hole position for every batch. We support fast prototype and stable mass production with consistent quality.

• ✅ Fluid chamber end cap for liquid and gas systems
• ✅ Pump housing cover for industrial pumping equipment
• ✅ Sensor enclosure for environmental monitoring devices
• ✅ Pressure vessel closure for test and calibration units

Q1: Can the side port thread be customized?

A1: Yes, internal or external threads on the side port can be machined according to your pipeline connection requirements.

Q2: What anodizing colors are available?

A2: Blue, black, natural silver and other custom colors can be done for aluminum anodizing.

Q3: Can you provide sealing groove machining?

A3: Yes, O-ring sealing grooves can be machined on the flange face if needed for sealing applications.

Q4: What is the maximum outer diameter you can machine?

A4: We can machine circular housings up to 300mm outer diameter. Larger parts can be discussed based on geometry.

Q5: What files are needed for quotation?

A5: 3D STEP or IGES file plus 2D drawing with tolerance and surface finish requirements is preferred.
