Guangzhou Xinyan Jin Additive Technology has delivered over 10 million tire mold 3D printed steel sheets, with exports to Japan, South Korea, India, Turkey, Malaysia, and other countries. The company’s parent factory operates in-house atomization powder production lines covering mainstream materials such as 17-4PH, 316L, 304L, 410, and 18Ni300, ensuring quality from the source. By independently optimizing LPBF process parameters, it achieves support-free and minimal post-processing efficient printing. A flexible production line of 16 industrial-grade printers handles batch orders of tens of thousands while enabling fast prototyping. As a vice-chairman unit of the Additive Manufacturing Branch of Guangdong Mechanical Engineering Society, the company led the formulation of the group standard 'Additive Manufacturing Tire Mold Steel Sheets.' Traditional stamping and milling methods can no longer meet the multi-angle, multi-thickness, multi-curvature production demands of 3D patterned groove steel sheets, making metal additive manufacturing the only viable solution.
