In September 2026, Sirui Additive (Shenzhen) Technology Co., Ltd. completed a Pre-A round in the tens of millions of yuan. Funding supports scaled preparation of printing powders for consumer electronics and liquid cooling, alongside multi-metal powder manufacturing and fine-adjustment R&D.
Funding Focus: Consumer Electronics, Liquid Cooling, and Powder Scale-Up
New investors include Tongkai Wanwei Venture Capital and a consumer-electronics industrial investor. Existing angel investor SUSTech Wutong Angel Fund invested again. Detai Capital advised the round.
The stated uses are specific: scale metal powder preparation for consumer electronics and liquid cooling, and further develop multi-metal powder production and fine adjustment.

Founded in 2023 by SUSTech Professor Yan Ming, Sirui develops and produces recycled titanium alloy and other advanced metal powders. Its proprietary cold-forming powder technology has yielded recycled TC4, TA1–4, and TA15 powders, plus ultra-high-strength and ultra-high-hardness titanium alloy powders. Applications include 3C electronics, decorative consumer products, medicine, automotive, marine engineering, and aerospace.
Sirui occupies upstream materials, rather than supplying thermal-management end products. Complex-channel requirements in liquid-cooling cold plates and manifolds are turning additive manufacturing from an option into an engineering choice. Powder batch consistency, oxygen control, and cost determine whether that route can scale.
Metal powders are printing's basic feedstock. As metal printing enters consumer-electronics manufacturing, end-product companies need materials meeting environmental and performance requirements and increasingly consider carbon footprints and recycled content. Sirui's current products and validation focus on consumer electronics, medicine, automotive, and aerospace; liquid cooling is a funding priority.
The performance ceiling of cold plates and distributors increasingly depends on channel-design freedom. Conventional machining limits complex channels, thin walls, and integrated construction. Printing permits more complex internal paths, increasing heat-transfer area and flow uniformity. Scaling nevertheless returns to powders: oxygen content, sphericity, size distribution, and batch consistency influence process stability and final performance.
The funding therefore signals more than one supplier's capacity expansion. Liquid-cooling competition is extending upstream. As cold-plate, CDU, and system-integration capacity races unfold, additive manufacturing of complex channels and the powder supply behind it are becoming a less visible but essential supporting chain.
