AI-Powered supplier vetting

SummaryThe supplier operates across equipment, electronic products, automotive parts, stamping products, and precision stamping dies, while also listing broad trading activities. It supports customization from samples and designs, full, minor, and flexible customization, and offers ODM services, but is not identified as a professional technical supplier and does not provide 3D software design services. Production information lists substantial stated volumes for fasteners, molds, stamping, and tight stamping, with an off-peak lead time within 15 workdays. Finished-product inspection instructions are reportedly established and uniformly followed. Financial records are referenced for 2021–2023, but no financial results are provided. Overseas service infrastructure is limited: no overseas showroom, agents, branches, or offline trade-show participation are reported. No new products were developed in the past year, and no SDK is available. Customer cases or named customer references are not provided.

After-Sales capabilityThe supplier reports no overseas showroom, overseas agents or branches, or participation in offline trade shows, and lists zero countries with overseas services. Tianjin Port is identified as the nearest service-related location, but no specific after-sales process or support commitment is provided.

R&D capabilityThe supplier reports one year of total R&D engineer experience, no new products in the past year, no SDK availability, and no 3D software design service. It does offer ODM services and describes prior involvement in R&D, production, and sales, but the available evidence indicates limited recent innovation capability.

Production capacityThe supplier states annual output of 100 sets for molds, 10,000,000 tons for fasteners, and 10,000,000 pieces each for stamping and tight stamping, with an off-peak lead time within 15 workdays. It also reports inspection instructions that are established and uniformly followed, although the unusual production units and lack of independent verification limit certainty.

Customization capabilityThe supplier explicitly supports customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also reports ODM service availability, providing direct evidence of broad customization support.

Product Q&A

Q:What are the unique features of the fasteners we produce?

Our fasteners are made of advanced alloy materials. They not only have high strength but also are far more corrosion-resistant than similar products. They can adapt to various harsh environments, ranging from high-temperature industrial workshops to wet outdoor projects, and their service life is greatly extended.

Q:Is the production process of fasteners complicated?

It is quite complicated and rigorous. Starting from the procurement of raw materials, it goes through multiple strict screening processes to ensure that the materials are pure and free of impurities. Then comes the precise cold heading and hot forging forming, with the dimensional tolerance being precisely controlled at every step. After that, surface treatment is carried out, such as galvanizing and Dacromet treatment. Finally, there are multiple rounds of quality inspections, leaving no minor

Q:How do we ensure the quality of fasteners?

We have a complete quality control system. High-precision testing equipment is equipped on the production line to monitor the product's dimensions, hardness and other indicators in real time. At the same time, each batch of products has to undergo sampling for salt spray tests, tensile tests, etc. Only when they fully meet or even exceed the industry standards will they be allowed to leave the factory, all to make customers feel assured when using them.

Q:What customization options are available?

We offer full customization, minor customization, and flexible customization. Options include customization from samples, customization from designs, and full customization to meet specific requirements.

Q:What are the lead times for orders?

During peak season, the lead time is 3-6 months. During off-season, the lead time is within 15 workdays.
