Decoding the Birth of an "Industrial Artwork": Lihuati's Titanium Flange Manufacturing Process Blueprint

Lihuati strictly controls its raw materials. Each batch of titanium (e.g., TA1, TA2, TC4) undergoes chemical and mechanical testing. Only materials that meet or exceed the standards are approved for production, eliminating quality risks at the source.

The forging window for titanium alloys is narrow, requiring precise temperature control. Lihuati uses intelligent controlled-atmosphere furnaces to evenly heat the billets, enhancing plasticity and preventing issues like coarse grain growth or overheating, ensuring successful forging.

This is the core step for strengthening the flange. High-temperature forging plastically deforms the titanium billet, leading to densification and grain refinement. By precisely controlling forging parameters, Lihuati significantly enhances the product's fatigue strength and toughness.

The forged flanges undergo processes like solution and aging treatment. This "finalizing" step relieves internal stresses, stabilizes the microstructure, and optimizes the titanium alloy's strength, plasticity, and corrosion resistance, bringing its comprehensive performance to an optimal state.

During the cold working phase, CNC lathes are used to machine the titanium forgings. Lihuati employs specialized tooling, optimized cutting parameters, and high-pressure cooling systems to manage cutting heat, ensuring dimensional accuracy and preserving the surface integrity of the workpiece.

The machining of bolt holes is critical, affecting flange alignment accuracy and sealing. Lihuati uses high-precision equipment to ensure hole position, diameter, and surface finish meet specifications, providing an ideal match for high-strength bolts.

Laser or stamp marking is used to apply material grade, standard number, pressure class, dimensions, and a unique traceability number in the designated area. This is not just identification but a representation of Lihuati's quality commitment, ensuring traceability throughout the product's lifecycle.

After all machining is completed, the flanges undergo a thorough cleaning to remove surface oils, cutting fluids, and metal debris. A clean surface is a prerequisite for subsequent non-destructive testing and long-term corrosion resistance.

This is the final and most comprehensive checkpoint before delivery. It includes:

• Dimensional Re-inspection: Full dimensional verification using equipment like coordinate measuring machines (CMM).

• Non-Destructive Testing (NDT): Ultrasonic Testing (UT) or Penetrant Testing (PT) to ensure there are no internal cracks, voids, or other defects.

• Surface Inspection: Verifying the surface finish of critical areas like sealing faces meets requirements.

Only products that pass all criteria receive their "shipping clearance."

Customized packaging solutions (rust-proof, shock-absorbing) are used based on product characteristics and customer requirements, ensuring the products arrive intact and are delivered safely and on time to clients worldwide.
