Turning an idea into a manufactured product in China involves multiple critical stages. This article outlines the end-to-end development process: concept design, 3D modeling, prototype creation, mold development, pilot runs, and final mass production. We discuss how to protect your IP with NNN agreements and design patents, select the right prototyping methods (CNC, 3D printing, SLA), and manage engineering change orders (ECOs). Understanding tooling costs, lead times, and the ‘golden sample’ approval process ensures your final product matches your vision.
