AI-Powered supplier vetting

SummaryShijiazhuang Huatao Import and Export Trade Co., Ltd. is a China-based limited trading company established in 2008 with 12 employees. It identifies as a professional technical supplier and offers 3D software design, ODM, and multiple customization options. However, the evidence indicates limited innovation activity, with one R&D engineer and no new products launched in the previous year. The supplier has no stated inventory, overseas warehouse, showroom, agent, or branch capability. After-sales procedures exist for service assessment, corrective actions, and complaints, but no written records were provided. The supplier has participated in an overseas trade show and reports service offerings in France, including installation, maintenance, repair, debugging, and training. No certification information, financial assessment evidence, production capability, or sufficiently detailed customer-case evidence is provided.

Supplier typeThe supplier is explicitly classified as a trading company and limited company, operating in wholesale and retail. Its profile indicates an intermediary/trading role rather than a documented manufacturing enterprise.

After-Sales capabilityThe supplier reports overseas debugging, maintenance, repair, training, and equipment installation services in France, and has procedures for service assessment, corrective actions, and complaint handling. However, the procedures have no written records, and the supplier has no overseas warehouse, showroom, agent, or branch, limiting the strength of the documented service infrastructure.

R&D capabilityThe supplier has one R&D engineer and provides 3D design and ODM services, but it launched no new products in the previous year and has no SDK available. This combination demonstrates some design capability but does not establish strong recent innovation performance.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization, together with 3D software design and ODM services. These statements directly support a broad customization capability.

Product Q&A

Q:What materials are used for the function layer of your corona rollers?

We provide two mainstream insulation options. The silicone roller uses imported high-performance silicone raw materials with nano-modified formula. The ceramic roller adopts imported high-purity alumina ceramic powder for plasma spraying. Both materials feature strong ozone resistance and stable insulation performance, suitable for different BOPP/BOPET film production demands.

Q:Can your corona rollers fit my existing film production line?

Yes. Our corona rollers are fully customized according to line parameters, compatible with all mainstream biaxial stretching film equipment. We support customized roller width, diameter and cooling structure to match line speeds from 80 m/min to 700 m/min.

Q:What quality tests will the corona roller undergo before delivery?

Every finished roller passes full pre-delivery inspection shown in our video, including high-frequency high-voltage corona discharge test, dynamic balance calibration, water pressure leakage test and coating adhesion test. Complete factory inspection reports will be provided together with shipments to guarantee stable on-site operation.
