CNC Milling and Drilling with Sandblasted Spray Coating for Aluminum 1100-H14 E-Cigarette Housings

Why Aluminum 1100-H14 Is Ideal for E-Cigarette Housing Manufacturing

Lightweight and Thermally Stable

Aluminum 1100-H14 provides excellent thermal conductivity, corrosion resistance, and structural stability. It is easy to machine and ideal for compact electronics that require precise assembly and heat dissipation.

• Density: 2.7 g/cm³

• Yield strength (H14 temper): ~125 MPa

• Highly formable and stable under CNC machining

Perfect for Cosmetic Surface Applications

This alloy has a clean metallic appearance and smooth grain structure, making it well-suited for decorative coatings and matte finishes used in handheld devices.

CNC Machining Workflow for E-Cigarette Housing Components

CNC Milling for Exterior Form and Internal Slots

We use high-speed CNC mills to form the external profile, surface contours, and internal compartments for:

• Battery compartments

• LED indicator windows

• USB-C charging port cutouts

Tolerances: ±0.02 mm across fit zones, ensuring clean assembly and functional integration.

CNC Drilling for Port Openings and Connector Points

CNC drilling creates precision holes for:

• Airflow channels

• Switch mounts

• Fastener points

Chamfering and depth control ensure smooth fits and structural consistency without post-processing.

Surface Treatment: Sandblasting and Spray Painting

Sandblasting for Surface Preparation and Matte Texture

Sandblasting removes any minor tool marks and ensures a uniform, fingerprint-resistant texture. It also improves coating adhesion and final finish quality.

• Achieves Ra: 1.6–3.2 µm

• Enhances visual appeal with soft-touch matte effect

Spray Coating for Color, Branding, and Protection

We apply spray paint finishes in controlled environments for premium color and surface quality:

• Custom matte, satin, or glossy finishes

• Color options: silver, black, white, navy, champagne, or brand-specific

• Coating thickness: 30–50 µm with uniform adhesion

This coating protects against scratches, skin oils, and minor impact damage while delivering high visual consistency.

Quality Control and Consumer Product Compliance

• Full dimensional inspection using CMM and optical vision systems

• Surface inspection under diffused lighting for cosmetic grading

• Coating adhesion and durability testing per ISO 2409

• Documentation: COC, RoHS/REACH compliance, custom QC per brand standards
