Three distinct brands, one shared mission — advancing surface solutions for manufacturers worldwide.
Gnosel is GUOWIN's B2B brand positioned as an End-to-End MRO Consumables Solution Expert for precision manufacturing. We don't just supply products — we deeply understand our customers' MRO consumables needs and design tailored, full-cycle solutions that span from product selection and technical consultation to after-sales support and continuous optimization. Through deep partnerships with a network of professional surface treatment enterprises, we deliver a comprehensive suite of precision finishing products — from SC Series abrasive sponges to polishing systems, functional inks, and the MSD600 automation platform — backed by dedicated technical support and custom development capabilities.
Our partner factories have deep-domain expertise built through years serving China's top-tier precision manufacturing ecosystem — including household names like Foxconn, BYD, Apple, Xiaomi, Ford, Midea, ChangYing Precision, Mercedes-Benz, and many other high-end manufacturers. This proven track record across 3C electronics, automotive, solar energy, precision hardware, aerospace, medical devices, and semiconductor sectors is the foundation of Gnosel's global expansion — bringing world-class MRO consumables solutions to manufacturers in North America, Southeast Asia, and beyond.

Gnosiq is GUOWIN's consumer brand born from a deep understanding of everyday household frustrations — especially in cleaning and organizing. Through user research across global markets, we identify real consumer pain points, then partner with leading manufacturers to co-develop smart, effective products that bring Chinese manufacturing precision and efficiency into homes worldwide. Gnosiq is built on one belief: the quality once reserved for industrial supply chains should be available to every family.
We don't just source products — we co-develop them with manufacturers. Each Gnosiq product starts with consumer insights, undergoes iterative engineering, and is held to the same quality standards that have proven themselves in the world's most demanding manufacturing ecosystems. The result: smart home products that actually work, last, and deliver a noticeably better experience.
