Precision-Engineered Ti-6Al-4V ELI Titanium Bars for Spinal Implants. We understand that quality is non-negotiable. That’s why our bars are consistently produced with a controlled microstructure (A3) and a minimum tensile strength of 1100 MPa, providing the proven reliability required for spine screws and other critical spinal devices.
How Huatainuo Ensures Uncompromising Quality in Medical Titanium Bars?
At Huatainuo, the quality of our medical-grade titanium bars is paramount, especially for critical applications like spinal implants. Our rigorous, multi-stage quality control system guarantees every bar meets the highest international standards. Here’s how we do it:
- Premium Raw Material Sourcing We begin with the finest O-grade undersized titanium sponge, ensuring the precise chemical composition required for superior biocompatibility and performance.
- Advanced Triple Vacuum Melting To achieve a uniform and pure microstructure, we employ a triple vacuum melting process using state-of-the-art German ALD furnaces. This eliminates impurities and ensures exceptional material integrity.
- Precision Thermo-Mechanical Processing Our closely controlled rolling and annealing processes are fine-tuned to deliver the optimal mechanical properties, including tensile strength and fatigue resistance, essential for medical devices.
- Comprehensive Testing & Verification
Every bar undergoes a battery of non-destructive tests:
- Internal Integrity: Ultrasonic and Eddy Current flaw detectors to identify any subsurface defects.
- Surface Perfection: Automated ODE optical surface detection combined with meticulous manual inspection.
- Dimensional Accuracy: Infra-ray diameter gauges to verify that tolerances are strictly maintained.
This end-to-end control over every production step is what makes Huatainuo a trusted partner for the most demanding medical applications.
