Technical Capabilities
Metal Injection Moulding (MIM) of titanium is a precision manufacturing process suitable for producing complex, high-strength components in large volumes. However, MIM titanium parts typically require secondary operations such as laser cutting, bending, and welding to achieve final dimensional accuracy or integration into assemblies. Below are the technical specifications and considerations for these processes when applied to MIM titanium components, with comparative notes on materials such as aluminum, steel, ABS, and nylon.
| Process | Titanium (MIM) | Aluminum | Steel | ABS | Nylon |
|---|---|---|---|---|---|
| Laser Cutting | Requires high-power fiber lasers (1–3 kW); reflective nature demands controlled assist gas (N₂ or Ar); kerf width ~0.1–0.2 mm; heat-affected zone (HAZ) must be minimized to prevent embrittlement | Easily cut with fiber or CO₂ lasers; low melting point; uses N₂ or O₂ as assist gas; kerf width ~0.1–0.15 mm; high reflectivity requires beam control | Compatible with high-power fiber lasers; uses O₂ or N₂; kerf width ~0.1–0.2 mm; moderate HAZ; high absorption rate | CO₂ lasers effective; low thermal conductivity; kerf width ~0.1–0.2 mm; risk of melting or charring | CO₂ lasers suitable; high melting point among thermoplastics; prone to thermal degradation; requires precise power control |
| Bending | Not typically applied to MIM parts due to small size and brittleness; if macro-structures, requires elevated temperature (300–500°C) and slow strain rates | Excellent formability at room temperature; common in sheet metal fabrication; springback ~2–5% | Good bendability with appropriate ductility; springback varies by grade (1–3°); requires high tonnage | Limited cold bending; prone to cracking; annealing may be needed for sharp bends | Moderate flexibility; can be bent at elevated temperatures; high moisture absorption affects dimensional stability |
| Welding | Requires full inert gas shielding (Ar); TIG or laser welding preferred; preheat (150–300°C) and post-weld annealing recommended to reduce cracking | Easily welded via TIG, MIG, or laser; high thermal conductivity requires preheat; good joint strength | Wide weldability (TIG, MIG, laser, spot); preheat often needed for high-carbon grades; post-weld treatment may be required | Ultrasonic, vibration, or laser welding; limited structural strength; low melting point enables fast processing | Compatible with hot-plate, ultrasonic, and laser welding; hygroscopic nature requires drying pre-weld |
| Typical MIM Use | High-volume, complex small parts (e.g., medical implants, aerospace fittings) | Not applicable – aluminum MIM is rare and limited to specialized applications | Common in MIM for automotive and industrial components | Not applicable – thermoplastics are processed via injection molding, not MIM | Not applicable – used in conventional thermoplastic injection molding |
Notes
MIM titanium components are generally net-shape and do not undergo extensive laser cutting or bending. These operations are more relevant when integrating MIM parts into larger assemblies or trimming feeders/gates. Welding is used selectively for joining titanium MIM parts to wrought titanium structures. In contrast, aluminum and steel are more commonly processed via sheet metal techniques involving laser cutting and bending, while ABS and nylon are thermoplastics used in conventional injection molding, not MIM.
From CAD to Part: The Process
Honyo Prototype Titanium Metal Injection Moulding Process Overview
Honyo Prototype specializes in high-precision titanium Metal Injection Moulding (MIM), leveraging our proprietary infrastructure to address the unique challenges of reactive metals. Our end-to-end workflow ensures technical rigor while accelerating time-to-part for demanding applications in aerospace, medical implants, and defense. Below is a technical breakdown of our validated process sequence.
Upload CAD
Clients initiate the process by uploading a 3D CAD model (STEP, IGES, or native formats) via our secure portal. For titanium MIM, we require explicit material specification (e.g., ASTM F136 Ti-6Al-4V ELI) and critical-to-function (CTF) features. Our system performs an initial geometric validation, flagging undercuts, thin walls (<0.5mm), or draft angles <1° that may compromise titanium part integrity during molding or sintering. Early-stage geometry feedback reduces iteration cycles, as titanium feedstock flow behavior differs significantly from stainless steel or superalloys.
AI-Powered Quoting Engine
Our AI quoting system analyzes the CAD geometry against 12,000+ historical titanium MIM builds, incorporating real-time variables:
Feedstock viscosity characteristics for titanium powder-binder systems
Sintering shrinkage prediction (18–22% linear for Ti-6Al-4V)
Secondary operation feasibility (e.g., HIP, machining)
Material cost volatility adjustments (titanium sponge pricing)
The output is a granular quote including NRE tooling costs, unit pricing at volume tiers, and a preliminary timeline. Crucially, the AI identifies high-risk geometries requiring DFM intervention—such as sections prone to warpage during vacuum sintering—before commercial commitment.
Titanium-Specific DFM Analysis
All titanium projects undergo mandatory Design for Manufacturability review by our MIM engineering team. This phase focuses on titanium’s metallurgical constraints:
| DFM Parameter | Titanium-Specific Threshold | Failure Risk Mitigation Strategy |
|---|---|---|
| Wall Thickness Uniformity | Min. 0.3mm, Max. 8mm | Split molds with thermal pin control to prevent sink marks |
| Surface Finish | As-sintered Ra 3.2μm achievable | Specify machining allowances for critical bearing surfaces |
| Binder Removal Rate | Max 0.15mm/hr in thermal debinding | Custom debinding cycle to avoid carbon contamination |
| Sintering Atmosphere | <10ppm O₂ in vacuum furnace | Inert gas purging validation pre-run |
| Support Structures | Required for overhangs >45° | Sacrificial supports designed for minimal post-breakage |
This stage typically resolves 92% of manufacturability issues. Clients receive a formal DFM report with annotated CAD markups and tolerance capability analysis per ASTM F2885.
Production Execution
Titanium MIM production occurs in our ISO 13485-certified cleanroom environment:
1. Feedstock Preparation: Gas-atomized titanium powder (<15μm D50) is compounded with proprietary polymer binder under argon atmosphere to prevent oxidation.
2. Molding: 100–300 ton hydraulic presses inject feedstock at 180–220°C; cavity pressure monitoring ensures homogeneity critical for titanium’s sintering density.
3. Debinding: Thermal debinding in nitrogen atmosphere (0.01–0.1°C/min ramp) removes 95% binder without carbon pickup.
4. Sintering: Vacuum sintering (1280–1320°C, 10⁻³ mbar) with controlled cooling rates to achieve >99.5% density and ASTM-compliant microstructure.
5. Post-Processing: Optional HIP (1200°C/100MPa), precision machining, or electropolishing per client specs. Every lot undergoes PMI verification and microstructure validation.
Delivery & Traceability
Final inspection includes CMM reports, sintered density measurements, and metallurgical certification (grain size, oxygen content). Parts ship in VCI-protected containers with full lot traceability—powder lot numbers, sintering furnace logs, and operator certifications included in the CoC. Typical lead time from CAD upload to delivery is 18–22 days for first-article titanium components.
Honyo’s titanium MIM process eliminates common pitfalls like carbon embrittlement or dimensional scatter through material science-driven controls. We maintain ASTM B348-compliant titanium powder inventory and dedicate two sintering lines exclusively to reactive metals, ensuring consistent quality for mission-critical applications.
