Embracing the new technology of 3D-printed sand molds, Zhonghang Tuoli is leading the way in process innovation for the aluminum casting industry.

Under the wave of intelligent manufacturing, 3D-printed sand mold technology—thanks to its core advantages in digitalization and intelligence—is driving a revolutionary transformation in the aluminum casting industry. Guizhou Zhonghang Tuoli Foundry Co., Ltd. is closely following industry trends and has taken the lead in adopting 3D-printed sand mold technology, seamlessly integrating traditional aluminum casting techniques with cutting-edge digital technologies to spearhead the upgrade of casting processes in the regional aluminum industry.

The 3D-printed sand mold process is an advanced casting technique that uses digital models and 3D printing equipment to print sand molds layer by layer. It boasts significant advantages such as a short sand mold production cycle, high molding accuracy, and great design flexibility. This process enables rapid fabrication of complex sand molds, effectively addressing the challenges associated with traditional sand mold casting—namely, the difficulty, long lead times, and high costs involved in producing sand molds with intricate structures. It is particularly well-suited for the production of highly complex, high-value-added, small-batch customized aluminum castings. After introducing this technology, Zhonghang Tuoli has assembled a specialized technical team dedicated to in-depth research and development, and has now mastered the entire process—from digital modeling and sand mold printing to casting production.

It is reported that the company has successfully produced a variety of complex aluminum castings—products that would have been difficult to achieve using traditional methods—by adopting 3D-printed sand mold technology. This approach has not only significantly shortened the production cycle but also markedly improved the dimensional accuracy and quality stability of the products. The introduction of 3D-printed sand mold technology represents an important step for Zhonghang Tuoli in putting its innovation-driven philosophy into practice, further enhancing the company’s diversified process portfolio. Looking ahead, the company will continue to increase its R&D investment in digital casting technologies, leveraging technological innovation to drive high-quality enterprise development and contribute to the upgrading of industry processes.
