Production Process
- Raw Material Preparation: Tantalum ore is processed through mineral processing, enrichment and reduction to extract high-purity tantalum sponge, which is then refined and melted multiple times in a vacuum arc furnace to produce high-purity tantalum ingots complying with R05200 standards, ensuring raw material purity.
- Drawing Analysis & Process Planning: Receive customers' 2D/3D drawings, accurately analyze dimensional, tolerance, structural and performance requirements, formulate exclusive machining process plans, and determine forming, machining and heat treatment processes.
- Blank Machining: Tantalum ingots are processed into sheet, strip or rod blanks through forging, rolling and other processes, ensuring that blank accuracy meets the drawing machining datum requirements.
- Precision Machining to Drawing: Carry out core machining according to the process plan. Fasteners undergo turning, milling and thread machining; accessories and custom parts undergo stamping, welding and special-shaped machining, with precision calibrated according to drawings throughout the process.
Production Process
- Annealing Treatment: Conduct intermediate annealing and finished product annealing according to drawing performance requirements, eliminate machining stress, adjust product delivery state (soft/hard state), and ensure mechanical properties and stability.
- Surface Treatment: Perform pickling, bright annealing or polishing treatment as needed to remove oxide scale and impurities, improve corrosion resistance and surface quality, and meet drawing appearance requirements.
- Finished Product Inspection & Calibration: Conduct full-dimensional inspection against customers' drawings, including dimensional accuracy, structural form, mechanical properties and sealing performance. Deliver products only after passing the inspection, with attached inspection reports and quality certificates.
