Core Engineering Advantages
Controlled Grain Flow via High-Pressure Forging
Unlike discs cut directly from standard rolled plates-which retain directional anisotropy-our open-die forged discs undergo multi-axis deformation under high hydraulic pressure.
• Metallurgical Benefit: The forging process breaks down the cast dendritic structure and refines the internal grain, aligning the metal flow lines (grain flow) along the contour of the disc.
• Performance Impact: This structural refinement significantly enhances resistance to crack propagation and fatigue failure under cyclical clamping and injection pressures in plastic molds.
High Strength-to-Weight Ratio & Reduced Equipment Load
• Density Advantage: Titanium alloys feature a density of roughly 4.43 g/cm3 (Grade 5), which is approximately 43% lighter than conventional mold steels (7.85 g/cm3).
• Operational Benefit: Utilizing titanium for large mold support plates, moving core plates, or high-speed automation tooling substantially lowers inertial loads, reduces wear on guide pins/bushings, and decreases energy consumption during high-cycle manufacturing.
Dimensional Stability in Thermal Cycling
Plastic injection molds experience continuous heating and cooling phases.
Grade 5 (Ti-6Al-4V) maintains stable mechanical properties up to 300°C to 350°C with a low coefficient of thermal expansion compared to aluminum.
This thermal stability minimizes core shifting, reduces flash formation, and extends maintenance intervals for precision multi-cavity molds.
Natural Corrosion Resistance
The passive titanium dioxide (TiO2) film that instantly forms on the surface provides inherent protection against aggressive chemical environments, outgassing from PVC/halogenated polymers, and water-cooling line scale build-up without requiring supplementary electroplating or coatings.

Quality Assurance & Non-Destructive Testing (NDT)
Every production lot undergoes rigorous inspection protocols to meet stringent industrial and aerospace specifications:
Raw Material Verification: Spectrographic analysis to confirm exact chemical composition against mill test reports (MTR).
Process Monitoring: Pyrometer-controlled heating furnaces and real-time hydraulic pressure logging during the forging stroke.
Ultrasonic Testing (UT): Internal integrity verified in accordance with standards such as AMS 2631 or ASTM E2375 to guarantee freedom from internal inclusions, laminations, or micro-shrinkage.
Dimensional Inspection: Verified using calibrated measuring equipment with complete CMM inspection reports available upon request.
Typical Industrial Applications
Plastic Injection Molding: High-cycle mold support plates, precision cavity backup pads, heat-barrier blocks, and lightweight moving slides.
Aerospace & Defense: Structural airframe rings, turbine engine components, and high-strength fasteners.
Chemical Processing: Tube sheets, pressure vessel flanges, valve bodies, and components exposed to aggressive media.
Precision Tooling: Custom machine fixtures and low-inertia automated components.

FAQ
Q: What is a titanium forged disc?
A: A titanium forged disc is a round titanium component manufactured through open-die forging, where raw material is shaped under intense hydraulic pressure to optimize its internal micro-structure and mechanical properties. Unlike discs cut directly from titanium plates, forged discs provide superior grain flow orientation and enhanced fatigue resistance under cyclic loads.
Q: What titanium grades do you supply for forged discs?
A: We primarily supply:
Grade 2 Titanium (UNS R50400): Ideal for corrosion-resistant industrial applications and chemical backing plates.
Grade 5 Titanium / Ti-6Al-4V (UNS R56400): The industry standard for high-strength mold inserts and structural tooling.
Custom aerospace and industrial alloys can also be sourced and forged upon request.
Q: Why choose forged titanium discs instead of standard titanium plates?
A: Forged titanium discs provide major technical advantages:
Optimized, continuous internal grain flow along the component contour
Higher resistance to crack propagation and fatigue failure
Improved mechanical reliability under repeated thermal and mechanical stress
Minimized risk of internal micro-voids common in certain plate-cutting scenarios
Q: Can you manufacture titanium forged discs to custom drawings?
A: Yes. We specialize in OEM custom manufacturing based entirely on your provided engineering drawings, CAD files, dimensional tolerances, and specific material standards.
Q: Are titanium forged discs suitable for plastic molds?
A: Yes. They are widely utilized in plastic injection molding for applications requiring high rigidity, lightweight construction, and thermal stability. They significantly reduce inertial loads on moving core plates and prevent core shifting during high-cycle runs.
Q: What quality and inspection documents are provided?
A: With every shipment, we provide comprehensive documentation packages, including Mill Test Reports (MTR / Material Certificates), chemical analysis reports, mechanical testing data, ultrasonic testing (UT) compliance records, and dimensional/CMM inspection reports upon request.
