Certainty, Forged in Partnership
Our story is, at its heart, a story of partnership.
It began in 2007, not with a single entrepreneur, but with a trio of founders: Mr. Tao, alongside two key technical partners. They were united by a shared frustration: an industry that treated the most critical component—the magnetic material itself—as a commodity to be purchased, not a quality to be mastered.
Their founding insight was radical in its simplicity: you cannot guarantee what you do not control.
This belief became their non-negotiable pact. They chose the harder path: to build, not just assemble. To begin with raw material compounding, formulating their own proprietary rubber magnetic sheets. To own the entire process, so that every variable of magnetic strength, flexibility, and durability was commanded from the origin.
That pact required more than technical skill; it demanded a rarer quality: enduring alignment. This alignment has been our bedrock for nearly two decades. It is why we invested in our 10,000-square-meter, wholly-owned and automated facility in Ningbo—not as a factory, but as the physical engine of our control. It is why we have unified our entire team under one roof, operating with the transparency and synergy that complex projects demand.
This unity of purpose is what we offer you. It translates into two forms of certainty:
1.As Your Premier Material Source: We provide exceptional rubber magnetic sheeting to distributors and fabricators worldwide. You gain a core material engineered for consistency, giving you a reliable foundation for your own manufacturing success.
2.As Your End-to-End Solution Partner: We act as a dedicated, full-service OEM manufacturer for global brands. From complex printing and precision die-cutting to final assembly, we offer a streamlined, accountable supply chain for the finished component.
Our integrated operation in Ningbo’s Ouchi Industrial Zone is the embodiment of this philosophy. It ensures that every roll of material and every finished part is built on the same foundation of control. This is how we achieve the batch-to-batch reliability required by international chains and e-commerce leaders, and why specialists across industries choose us as their partner for critical projects.
From a pact between three founders, to a promise to you. Certainty, built from the source, and sustained by partnership.
