Wenzhou Metal 3D Printing Company Wins NVIDIA Supply-Chain Cold Plate Orders Through Year-End

Source: Wenzhou Evening News.

AI computing demand is accelerating, making liquid cooling standard for high-power servers and creating a rapidly expanding market.

At Toptra Laser Technology (Wenzhou) Co., Ltd. in Wenzhou Bay New Area's Binhai Industrial Park, 15 metal printers run at full capacity. Complex liquid-cooling components are built layer by layer and then undergo leak testing. These “computing cold plates” support a new generation of AI servers through orders connected with NVIDIA's supply chain.



Marketing director Mr. Zhao said orders were fully booked through the end of 2026, with continued overtime during the Mid-Autumn and National Day holidays. Toptra Laser Technology (Hangzhou) provides end-to-end metal printing solutions focused on tooling. In June, it established an advanced manufacturing center in Wenzhou Bay New Area, Longwan District, to serve local automotive and motorcycle parts tooling, footwear and apparel molds, and precision industrial electrical molds.

Zhao said Wenzhou has a strong mold industry. The company's internally developed Toptra material system has been applied across industrial settings. Liquid-cooling orders increased significantly in 2026. After entering Wenzhou, it quickly expanded into AI server cooling and received its first orders from core supply-chain companies including NVIDIA tier-one supplier Foxconn at the end of July.



Liquid cooling places higher demands on AM, materials and process precision. Zhao said competition is intense and processes continually evolve. Toptra's advantage is closer integration of powder materials, equipment and printing processes. Its internally developed high-performance tool steel powder offers strength in hardness, corrosion resistance and heat conduction. Collaboration with leading equipment maker Eplus3D includes customized and jointly developed systems for precise batch production.

Zhao identified three strengths: proprietary materials with suitable thermal and structural performance; one-piece fabrication reducing leakage risks under pressure; and consistent batch quality through the complete process. The equipment can print up to 32 tonnes of tooling material annually, with a maximum build travel of 650 mm.

The company has three production lines with monthly output of approximately 1,000 parts, mainly for AI server liquid cooling. The first printed manifolds were delivered in August. The NVIDIA-related project order comprises 50,000 pieces valued at RMB 30 million. Five additional printers have been purchased to meet demand.

A Wenzhou Bay New Area emerging industries official said Toptra achieved orders and production within five months of entering the New Optics Valley, illustrating Longwan's industrial upgrading. Alongside established industries, the district is developing laser and photonics and AI computing support, with projects covering metal AM, fiber laser R&D and production headquarters, and high-power intelligent laser-cutting CNC equipment. The share of high-tech industry continues to rise.
