This strategic investment represents another important move by Tiangong International in the PCB tool sector, marking a solid step forward in extending its core industrial chain presence in PCB tools.

Strategic Investment in WELL-SUN to Boost PCB Tool Sector Presence

Founded in 2000, WELL-SUN's core product portfolio covers three major categories—drills, milling cutters, and grinding heads—with deep applications in printed circuit board (PCB) precision machining, mechanical manufacturing, nail care, and dental medical fields. As a leading supplier of PCB drilling needles, WELL-SUN's core competitive edge lies in its in-house capabilities in designing and equipping industrial machine tools, with its business now covering multiple industries.

According to publicly disclosed information, WELL-SUN achieved operating revenue of RMB 210.54 million and net profit of RMB 24.52 million in 2025. In the first half of 2026, it recorded operating revenue of RMB 149.44 million and net profit of RMB 36.69 million, representing year-on-year growth of 60.2% and 457.6%, respectively, compared with the same period in 2025, demonstrating rapid operational performance growth.

Full-Industry-Chain Synergy to Empower a New Ecosystem for High-End Manufacturing

As the industrial platform under Tiangong International specializing in the manufacturing of high-speed steel and cemented carbide tools, Tiangong Precision has already made substantial investments in PCB precision machining tools and alloy bar materials through its subsidiary, Jiangsu Tiangong Cemented Carbide Technology Co., Ltd. This strategic investment in WELL-SUN will further strengthen collaborative business relationships between Tiangong Precision and downstream enterprises in areas such as material R&D, manufacturing and supply, as well as in different types of tool applications.

Looking ahead, the Company will continue to deepen strategic partnerships with high-quality downstream enterprises, focus on core high-end manufacturing segments, enhance technological R&D and industrial synergy, and empower tool manufacturing upgrades through material innovation, contributing Tiangong's strength to the high-quality development of China's high-end manufacturing sector.
