Qingdao Blue Diamond Industry Co., Ltd. — a professional custom manufacturer of rubber, plastic injection, and self-skinning PU foam products since 2008.
Founded in 2008 and headquartered in Qingdao’s premier high-tech industrial zone, Blue Diamond Industry has evolved from a specialized mold-making workshop into a global powerhouse of polymer manufacturing. We design, formulate, and manufacture custom rubber molding, precision engineered plastics, and custom polyurethane (PU) foam structures.
Our engineering-first approach ensures that we don’t just take orders — we co-design and optimize your CAD drawings to lower tooling costs, guarantee tight physical tolerances, and recommend the exact material compound for your specific chemical, thermal, and mechanical requirements.
