AI-Powered supplier vetting

SummaryShandong Jiaguang International Trade Co., Ltd. is identified as a Chinese manufacturer/factory specializing in boiler accessories, with stated manufacturing experience, a modern production base, and a senior technical team. The supplier reports ISO9001, CE, and SGS origin certifications, and offers 3D design, ODM, OEM, and multiple customization options. However, the evidence also shows no valid manufacturing-capacity contract with related subcontractors, no inventory, overseas warehouse, overseas showroom, overseas agents or branches, or offline trade-show participation. Quality procedures exist, but approved-supplier records, corrective/preventive-action records, and complaint-handling records are incomplete. Financial credibility cannot be established from the provided data because the reported financial figures are zero and no further verification is available. Customer cases are not specifically documented.

Supplier typeThe supplier is identified as a manufacturer/factory and a high-tech enterprise specializing in the R&D, production, sales, and service of boiler accessories. Its company type is also recorded as combined, with operations in manufacturing and industrial equipment-related sectors.

CertificationsThe company states that it has passed ISO9001 international quality system certification, CE certification, and SGS origin certification. Quality assurance is also reported in its quality-control processes, although several supporting quality records are incomplete.

R&D capabilityThe supplier is described as a professional technical supplier with R&D capability, 3D software design services, ODM services, and a senior technical team. However, it reported no new products in the past year and has no available SDK, so evidence of recent product innovation is limited.

Customization capabilityThe supplier provides 3D software design services and supports customization from designs, samples, full customization, minor customization, and flexible customization. It also reports ODM and OEM capabilities, directly supporting a broad customization offering.

Product Q&A

Q:What causes jamming or freezing of the scale grate?

Caused by plate deformation, foreign object blockage, insufficient lubrication, or installation deviation. Solutions include cleaning debris, replacing plates, lubricating, and correcting alignment.

Q:How to solve serious coal leakage in the scale grate?

Caused by excessive gaps, poor coal quality, or scale closure issues. Adjust plate gaps, control coal particle size (10-25mm), and check the closure mechanism.

Q:Why does the scale grate chain elongate or break?

Due to high-temperature fatigue, overload operation, or poor lubrication. Replace with high-temp alloy chains, control load, and use high-temperature grease regularly.

Q:How to prevent grate burning or rapid oxidation?

Use heat-resistant materials, ensure uniform air distribution, and cool down slowly after shutdown to avoid cold air shock and oxidation.

Q:What causes unilateral wear or deviation of the scale grate?

Caused by uneven chain tension, worn guide rails, or misaligned drive shafts. Adjust chain tension, repair rails, and correct shaft parallelism.
