Manufacturing Process & Quality Control

High-Quality Raw Materials: Utilizing high-purity titanium sponge and alloy elements, produced through advanced vacuum melting technologies (e.g., Vacuum Arc Remelting - VAR) to create high-purity titanium ingots, ensuring the quality of the bar's material source.

Precision Bar Forming: Subsequently, titanium bars/rods are manufactured through rigorously controlled forging, hot rolling, and precision cold drawing and/or cold rolling processes, optimizing grain structure and ensuring their density, uniformity, and excellent mechanical properties.

Precision Heat Treatment: Implementing precise annealing, solution treatment, and/or aging treatments to relieve processing stress, optimize grain structure, and ensure the material's ductility, strength, and long-term stability in use.

High-Precision Machining: Offering turning, grinding, polishing, and other machining services to ensure precise bar dimensions and surface finish, meeting high-precision application demands.

Rigorous Quality Testing (INSPECTIONS):

Raw Material Inspection: Chemical Composition Analysis (Spectro Test).

Internal Flaw Detection: Ultrasonic Testing (UT) and/or Eddy Current Testing (ET) are performed on finished bars to ensure the absence of internal cracks, inclusions, porosity, and other defects.

Geometric Dimensions & Visual Inspection: Precise measurement of diameter, length, straightness, ovality, and high-precision visual and automated inspection for surface defects (e.g., scratches, indentations).

Mechanical Properties Testing: Tensile Test (Elongation, Yield Strength, Tensile Strength), Hardness Test, Impact Test, Bend Test, etc.

Metallographic Analysis: Evaluation of grain size and microstructure to ensure conformity with standards and final application requirements.

Corrosion Testing: Corrosion tests in specific corrosive media (e.g., ASTM G28, G48) are performed to verify durability in harsh chemical environments.

Traceability: Comprehensive material reports are provided, ensuring complete traceability from raw material to final bar/rod, with support for independent third-party certification.
