TOPWAY SPRINGS

Dalian TopWay Precise Mould & Die Co., Ltd. is a professional precise mould and die parts manufacturer. The company operates two specialized business units: the Spring Division and the Mould Parts Division.

As a technology leader in China's rectangular spring industry, the Spring Division specializes in the R&D, engineering, and precision manufacturing of high-performance industrial springs. We provide a complete one-stop solution integrating sales, technical consultation, custom design, manufacturing, and global export support. By actively introducing advanced production technologies, automated coiling and grinding equipment, and strict quality control systems from Europe, Japan, and the United States, TopWay manufactures world-class springs that strictly adhere to ISO 10243, JIS B5012, and American Standard (Inch series) specifications.

As a certified OEM manufacturing partner for leading international mold component brands, TopWay delivers 100% quality parity with global market leaders. Our spring products are crafted exclusively from high-stress oil-tempered alloy steels (such as 55CrSi ) and processed through precision shot-peening and multi-stage tempering. This ensures superior tensile strength, exceptional resistance to thermal relaxation, and an extended fatigue life capable of withstanding 3 to 5 million high-frequency compression cycles under extreme working conditions.

In addition to our standard catalog lineup, TopWay maintains a massive ready-to-ship inventory to support immediate dispatch and rapid lead times. We also offer full OEM/ODM customization—tailoring wire profiles, load specs, non-standard dimensions, durable color-coded powder coatings, and private branding according to client drawings or physical samples.

TopWay Series springs are widely trusted across a broad spectrum of demanding industrial applications. In addition to automotive stamping dies, plastic injection molds, and die-casting tooling, our springs are extensively utilized in industrial automation, elevator systems, machine tools, engineering machinery, environmental filtration equipment, high-voltage electrical switches, valves, and heavy-duty energy systems.

TopWay remains unswervingly committed to the pursuit of perfect quality and high-end manufacturing. Driven by high quality, factory-direct cost efficiency, fast delivery, and dedicated customer service, we strive continuously to maximize value for our global partners and drive the advancement of national precision manufacturing!
