The Innovation Journey of Ultra-Fine Tin Wire: From 0.5mm to 0.12mm — Interview with Mr. Tsoi, Chairman of Victory Technology International LTD

Published on December 25, 2023, by China Nonferrous Metals News, this interview spotlights Victory Technology International LTD (based in Dongguan, Guangdong) and its remarkable breakthrough in ultra-fine tin wire technology. As a leading manufacturer of solder production equipment, the company has shattered the long-standing technical barrier by reducing the terminal diameter of ultra-fine tin wire from 0.5mm to 0.12mm — a gap-filling achievement that meets international standards.

A Decade of R&D for a Millimeter Leap

What does 0.12mm signify? Slightly thicker than a human hair, this ultra-fine specification required 10 years of dedicated R&D to overcome foreign technological monopolies. The production process involves mixing tin ingots with metals like silver, copper, and bismuth, then melting, casting, extruding, and drawing the material step-by-step. Thinner wire not only demands stricter precision but also delivers higher added value, with a significantly higher selling price per kilogram.

From Humble Beginnings to Technological Leadership

Founded in 1996 (formerly Keju Machinery Factory), Victory Technology initially focused on wire and cable equipment. It pivoted to tin solder gear after identifying industry pain points: limited domestic R&D, reliance on expensive imported equipment, and costly after-sales delays.

The company’s innovation journey evolved steadily:

• 1990s: Transitioned from manual to automatic feeding, solved oxide slag issues, and adopted multi-die continuous drawing.
• 2000s: Upgraded to electromagnetic induction heating and automatic casting, replacing outdated rolling mills with self-developed models for higher efficiency.
• Recent Years: Mastered 0.12mm ultra-fine tin wire production, developed tin powder equipment meeting J-STD-006 standards, and expanded into zinc, bismuth, and aluminum powder gear — overcoming unique challenges like aluminum’s high oxidation and explosion risks.

Global Expansion & Customer-Centric Service

Victory Technology has transformed from an importer to an exporter, supplying equipment to 43 countries across Africa, the Americas, Europe, and Southeast Asia. Its success stems from:

• Quality Commitment: Prioritizing product reliability as the "soul of the enterprise."
• End-to-End Support: Offering turnkey solutions, from workshop layout to process guidance, and rapid troubleshooting.
• Fission Growth: Winning repeat business from global giants, expanding from single factories to multi-site partnerships.

Honors & Future Vision

Boasting titles like "High-Tech Enterprise" and "Guangdong Famous Brand," the company plans to deepen smart equipment R&D, integrate industry-academia-research resources, and lead green development in deep processing. Mr. Tsoi emphasizes: "Serving enterprises with quality equipment is our social responsibility. We aim to support employees and drive industry win-win development."
