Daidocn.com is the official website of Shanghai Datong Spring Co., Ltd. According to the site content, the company is a wholly owned subsidiary established in China by Japan’s Daido Spring Co., Ltd. Located in the Songjiang Industrial Zone of Shanghai, it mainly designs and manufactures round-wire and square-wire metal springs. The website includes sections for product categories, a shopping cart, catalog downloads, a mini program, and online inquiries, but its overall positioning is closer to that of an industrial B2B supplier’s official website than a standardized open e-commerce platform.
Its products cover three main categories: rectangular springs, round-wire standard parts, and non-standard custom products. These include rectangular springs with different load ratings such as YEL, BLU, RED, and GRE; SUS304WPB stainless steel and SWPB piano wire standard parts; as well as compression springs, extension springs, torsion springs, retaining springs, close-wound springs, and more. Its key strengths include inventory of tens of thousands of standard parts, no minimum order quantity, delivery from a single piece, and support for customization based on drawings or samples. On the supply chain side, the site mentions its own 12,800㎡ factory, dozens of Japanese-imported coiling machines and inspection devices, custom wire diameters from 0.1 mm to 20 mm, and warehouses for raw materials and semi-finished products.
The website does not disclose specific prices, tiered pricing, shipping fees, or payment methods. Purchasing will most likely require inquiries by phone, WeChat, or online message. Fulfillment information is relatively detailed: it claims ample inventory of standard parts, stocked common raw materials, rapid sample production within one week, and more than 20 agents nationwide for nearby service. However, logistics carriers, delivery-time commitments, and return/exchange policies are not clearly disclosed.
The advantages are a relatively comprehensive specification system, suitability for high-precision industrial applications, support for small batches and non-standard customization, and backing from factory capacity, equipment, inspection capabilities, and engineering support. The drawbacks are insufficient e-commerce information and a lack of transparent mechanisms such as online quotations, payment, order status tracking, and after-sales SLAs. It is not very friendly to ordinary retail buyers or procurement staff who need quick price comparisons.
It is suitable for procurement and R&D prototyping users in industries such as automotive, molds, valves, elevators, machinery, electrical appliances, rail transit, and medical equipment, especially companies that need in-stock standard springs or high-precision custom products. The site is a Chinese ICP-registered website, and based on the content, it should be directly accessible from mainland China.
