Manufacturing Insight: Anodised Titanium Ring Production

Titanium rings present unique manufacturing challenges and opportunities due to the material’s exceptional strength-to-weight ratio, biocompatibility, and corrosion resistance. Anodisation transforms these functional attributes into compelling aesthetic and performance features through a precisely controlled electrochemical process. Unlike anodisation on aluminum, titanium anodisation is primarily a coloring technique that alters surface oxide layer thickness via voltage application, generating vibrant, durable hues without dyes or pigments. This process enhances surface hardness slightly and maintains the substrate’s inherent corrosion resistance, making it ideal for high-value applications in medical, aerospace, and luxury consumer goods where appearance and longevity are critical.

At Honyo Prototype, we leverage our deep expertise in CNC machining and surface engineering to deliver exceptional anodised titanium rings. Our integrated workflow begins with precision CNC turning or milling of ASTM F67 or F136 grade titanium billet, achieving tight tolerances down to ±0.005mm. Critical to successful anodisation is meticulous surface preparation; we employ multi-stage cleaning and etching protocols to ensure optimal adhesion and uniform oxide growth. Our proprietary anodisation process utilizes computer-controlled rectifiers to apply specific, stable DC voltages within a certified electrolyte bath. Voltage directly dictates color – lower voltages yield bronze or blue tones, while higher voltages produce vibrant purples, greens, and golds. This voltage-to-color relationship allows for exceptional repeatability and customization.

Honyo’s advanced capabilities ensure consistent, high-fidelity results even on complex geometries. We maintain rigorous environmental controls within our dedicated anodising facility, including temperature-stabilized baths and ultra-pure water systems, minimizing batch variation. Our process is optimized for low-volume, high-mix production typical of prototyping and pre-production runs, enabling rapid iteration on color specifications without minimum order constraints. Crucially, we implement stringent in-process metrology, verifying oxide thickness and color consistency using spectrophotometers and interferometry to meet exacting client specifications.

Technical Capabilities

Technical Capabilities: Precision CNC Machining for Anodised Titanium Rings

Shenzhen Honyo Prototype specializes in high-precision CNC machining for advanced material components, including anodised titanium rings used in aerospace, medical, and high-end consumer applications. Our in-house 3-axis, 4-axis, and 5-axis milling capabilities, combined with precision CNC turning, enable us to produce complex ring geometries with superior surface integrity and dimensional accuracy. Titanium, particularly grades such as Ti-6Al-4V (Grade 5) and commercially pure Grade 2, presents unique challenges due to its low thermal conductivity and high chemical reactivity. However, our optimized toolpaths, cryogenic cooling strategies, and rigid machine setups ensure consistent part quality and extended tool life.

Our machining process begins with billet or bar stock titanium, which is first turned to near-net shape using high-speed CNC lathes with live tooling for secondary features such as flats, holes, or grooves. Subsequent milling operations on 4-axis and 5-axis platforms allow for complex contouring, chamfering, and precision slotting without multiple re-fixturing, minimizing cumulative error and improving geometric consistency. We maintain tight control over spindle runout, tool wear, and environmental temperature to support tolerances down to ±0.005 mm on critical diameters and face features.

Following CNC fabrication, titanium rings undergo an electrochemical anodising process that enhances surface durability, corrosion resistance, and aesthetic appeal. Our anodising protocol is tightly integrated with the machining workflow to preserve dimensional stability. Since anodising generates a thin, non-conductive oxide layer (typically 0.5–5 µm), we account for this in final dimensioning—especially for press-fit or sealing surfaces—by adjusting machining tolerances accordingly. The anodised layer also supports color coding via interference effects, allowing for custom visual identification without dyes.

All processes are supported by full inspection using coordinate measuring machines (CMM), optical comparators, and surface profilometers to verify compliance with drawing specifications. First article inspection (FAI) and PPAP documentation are available upon request.

From CAD to Part: The Process

Manufacturing Guide: Anodised Titanium Ring Production Process

At Shenzhen Honyo Prototype, our CNC machining workflow for anodised titanium rings prioritizes precision, material integrity, and seamless integration from digital design to finished component. This standardized process—AI Quote → DFM → Production—ensures optimal manufacturability while minimizing lead times and cost overruns for B2B clients.

The workflow initiates with an AI-powered quoting system that analyzes the client’s CAD file (STEP/IGES format) against our CNC capabilities and titanium-specific parameters. This step evaluates geometric complexity, wall thickness, and critical tolerances to generate an instant, data-driven cost and timeline estimate. Crucially, the AI flags potential manufacturability risks early, such as undercut geometries or thin sections prone to chatter during machining, establishing transparent supply chain expectations before project kickoff.

Following quote acceptance, the Design for Manufacturability (DFM) phase commences. Our engineering team conducts a rigorous titanium-specific review, focusing on material behavior. Titanium’s low thermal conductivity and high reactivity necessitate adjustments: optimizing toolpaths to prevent heat buildup (which causes galling or micro-welding), specifying sharp carbide tooling with aggressive chip evacuation, and reinforcing thin ring walls via temporary support structures in the CAD model. We also validate anodising requirements here, confirming surface finish prerequisites (e.g., Ra ≤ 0.8 µm) to ensure uniform oxide layer growth and color consistency. Client collaboration during DFM avoids downstream rework, directly impacting yield rates and repeat business.

Production leverages 5-axis CNC milling for monolithic ring fabrication from ASTM F136 Ti-6Al-4V bar stock. Machining occurs in climate-controlled environments to mitigate thermal drift, with in-process CMM checks at critical stages (e.g., post-roughing, pre-finishing). Key parameters include low SFM (surface feet per minute), high-pressure coolant for chip control, and peening-free tool engagement to preserve surface integrity. Post-machining, rings undergo precision vibratory deburring to eliminate micro-burrs that could disrupt anodising. The anodisation sequence follows immediately: ultrasonic cleaning, etching in dilute HF/HNO₃, then controlled voltage ramping in electrolytic baths to achieve target interference colors (e.g., 35–75V for blues/purples). Final inspection validates dimensional compliance, color uniformity, and adhesion per ASTM F86.

This integrated workflow guarantees that every anodised titanium ring meets aerospace-derived quality standards while accommodating bespoke design demands. Below are critical production specifications:

| Parameter | Specification | Standard/Method |

|——————–|———————————–|———————–|

| Material | ASTM F136 Ti-6Al-4V ELI | AMS 4928 |

| Dimensional Tolerance | ±0.025 mm (critical features) | ISO 2768-mK |

| Surface Finish | Ra ≤ 0.8 µm (pre-anodise) | ASME B46.1 |

| Anodise Thickness | 0.5–2.5 µm (color-dependent) | ASTM F2129 |

| Color Consistency | ΔE < 1.5 (within batch) | CIE Lab* |

| Lead Time | 12–15 working days (avg. batch) | From DFM approval |

By anchoring production in titanium-specific DFM rigor and closed-loop process control, Honyo Prototype delivers anodised rings with repeatable aesthetics and structural reliability, directly supporting our clients’ high-end product deployments.
