Custom Smartphone Bezel Frames Manufactured to Your Design
We manufacture custom metal bezel frames for smartphones and compact electronic devices from customer-supplied CAD drawings and engineering specifications.
Each frame can be customized for dimensions, wall thickness, openings, mounting features, surface finish and cosmetic requirements. CNC milling allows us to produce complex profiles, pockets, button openings, camera cutouts and other precision features without dedicated production tooling.
From single prototypes to production batches, our machining process is adapted to the required geometry, material, tolerance and volume.
What Can Be Customized?
Dimensions
Custom overall dimensions according to your CAD drawing.
Wall Thickness
Thin-wall structures can be reviewed during DFM to reduce deformation risk.
Openings
Camera openings, buttons, speakers, USB ports, sensors and other interfaces.
Internal Features
Pockets, ribs, locating structures, screw holes and assembly interfaces.
Surface Finish
Anodizing, polishing, brushing, bead blasting, plating and other specified treatments.
Branding
Laser engraving, logo marking and other identification requirements.
Materials for CNC Smartphone Bezel Frames
| Material | Why Use It | Typical Applications |
|---|---|---|
| Aluminum 6061 | Lightweight, machinable, anodizing-friendly | Phone frames, housings |
| Aluminum 7075 | Higher strength-to-weight ratio* | Structural frames |
| Stainless Steel 304 | Strength and corrosion resistance | Premium metal frames |
| Stainless Steel 316L | Corrosion resistance* | Specialized electronics |
| Brass | Machinability + decorative appearance | Decorative components |
| Custom Alloys | Project-specific requirements | Special applications |
CNC Machining Process for Smartphone Metal Frames
A controlled workflow from CAD to finished frame — each stage is reviewed against the drawing before machining.
Engineers review wall thickness, corner radii, internal pockets, openings, tool accessibility and critical tolerances before machining.
Alloy selected and confirmed against the drawing and required finish.
Main profile and material removal performed with controlled cutting strategy.
Critical openings, thin walls and cosmetic surfaces finished to the drawing.
Edges and openings deburred for clean handling and assembly.
Anodizing, polishing, brushing, blasting or other specified treatment applied.
Critical dimensions verified with precision inspection equipment.
Appearance, surface and fit verified against the approved sample and drawing.
Protected packaging for transit and global delivery.
Surface Finishing Options
The finish defines appearance, feel and protection — and it can change dimensions. Select the finish for the required function and appearance, not a default.
Anodizing — Natural
Clear anodized finish for corrosion protection and a clean metallic look.
Aluminum*Anodizing — Black
Classic dark metal finish, broad color acceptance on Type II.
Type II / III*Anodizing — Custom Colors
Brand-specific color where the process supports it; confirm on a sample.
Custom color*Brushing
Fine brushed, directional grain finish on aluminum or stainless.
Specify grain*Polishing
Satin or mirror finish on aluminum, stainless or brass.
Removes material*Bead Blasting / Plating / Laser
Matte texture, plating and laser engraving for logos and identification marks.
Per capability*Finishing capability follows the base material and process — confirm the exact finish with our team. See the CNC Surface Finishing Guide for the full material-to-finish matrix.
Precision Machining & Quality Inspection
Every production order is reviewed against the approved CAD model and technical drawing. Critical dimensions can be verified using precision inspection equipment, with dimensional reports available according to project requirements.
| Quality Item | Capability |
|---|---|
| Dimensional Inspection | CMM / precision measurement |
| Critical Dimensions | Drawing-specific inspection |
| Material Verification | Material certification available |
| Surface Inspection | Visual + finish verification |
| First Article Inspection | Available for qualified projects |
| Final QC | Before shipment |
CNC Design Guidelines for Smartphone Frames
Design choices decide machinability, deformation risk and cost. These are the review points our engineers apply to your frame.
| Design Factor | Recommendation |
|---|---|
| Wall Thickness | Depends on material and geometry |
| Internal Corners | Use practical tool radii |
| Deep Pockets | Review tool access during DFM |
| Thin Features | Minimize unsupported thin sections |
| Critical Tolerances | Identify only functional dimensions |
| Threaded Holes | Specify thread standard and depth |
| Cosmetic Surfaces | Identify cosmetic faces on drawing |
| Surface Finish | Specify finish and appearance standard |
For thin-wall frame structures, wall thickness, geometry, workholding and material are confirmed during DFM rather than published as a blanket product parameter.
From Prototype to Production
The same DFM rigor and quality control apply at every quantity — from a single prototype to high-volume production.

The frame required thin-wall machining while maintaining dimensional stability around multiple openings.
Engineering SolutionWe optimized the machining sequence and workholding strategy to reduce deformation during finishing operations.
ResultConsistent geometry and surface appearance across the production batch, verified by dimensional inspection.
Related verified portfolio result: 6061-T6 aluminum electronic enclosures produced at 20,000 pieces with ±0.02 mm bore concentricity, bead-blasted then hard-anodized Type III, with zero rejects in final inspection. See CNC Machining Services for full capabilities.
Frequently Asked Questions
Can you manufacture custom smartphone metal frames from our CAD drawing?
Yes. We manufacture custom frames according to customer-supplied 3D CAD models and 2D engineering drawings.
What materials can be used for CNC smartphone frames?
Common options include 6061 and 7075 aluminum, 304 and 316L stainless steel, brass and other engineering metals depending on the design requirements.
Can you produce thin-wall aluminum phone frames?
Yes. Thin-wall structures can be CNC machined, but wall thickness, geometry, workholding and material must be reviewed during DFM.
What surface finishes are available?
Depending on material and appearance requirements, options include anodizing, bead blasting, brushing, polishing, plating and laser engraving.
Can you make prototypes before mass production?
Yes. Prototype and low-volume CNC production can be ordered before moving to larger production quantities.
What files should I send for quotation?
A 3D CAD model plus a dimensioned 2D drawing is recommended for the most accurate DFM review and quotation.
What is the minimum order quantity?
Prototype quantities starting from 1 piece can be supported, with production pricing determined by material, geometry and order quantity.
