AI-Powered supplier vetting

SummaryThe supplier is identified as a trading company associated with manufacturing-sector entities and located in Dacheng County, Langfang. It provides customized production, technical consultation, after-sales installation, and maintenance, with reported domestic coverage across residential, commercial, and industrial applications, including cooperation on a landmark airport project. The supplier reports flexible customization, ODM, recent new-product activity, and OEM service for well-known brands. Quality controls include raw-material traceability, random finished-product inspection, one quality inspector, written service procedures, corrective-action processes, and complaint-handling records. It has inventory capability and lead times within 15 workdays in both peak and off-season, but lacks overseas warehouses and showrooms and has no valid manufacturing-capacity contract with affiliated subcontractors. Financial evidence is inconsistent across the provided records, so credibility cannot be conclusively...

After-Sales capabilityThe supplier reports after-sales installation and maintenance, documented service procedures, corrective and preventive action procedures, and complaint-handling records. It also has inventory capability and stated lead times within 15 workdays, although it lacks overseas warehouses and overseas showrooms.

R&D capabilityThe supplier reports new products during the past year, ODM service, and broad design customization capabilities. However, it reports no available SDK, so the evidence supports product development and design capability but not software-development integration capability.

Customization capabilityThe supplier explicitly provides customization from samples and designs, full and minor customization, and flexible customization, as well as ODM services. These statements directly demonstrate broad customization coverage.

Client casesThe supplier states that it serves residential, commercial, and industrial markets and cooperated on a landmark project involving Beijing Capital International Airport. It also reports OEM service for well-known brands, providing direct evidence of customer and project experience, although specific customer names are not supplied.

Product Q&A

Q:Do you provide free samples?

Yes, free small samples (A4 size or 1m long roll) are available. Generally, the buyer only needs to bear the courier cost. Customized thickness or composite samples may require a small additional fee.

Q:Are your product dimensions fixed?

No. The standard width is fixed at 1200mm, while the length can be customized according to project requirements (e.g., 10m/20m rolls). Custom thicknesses (beyond 1.2/2/3mm) are also available.

Q:What are your payment terms?

We accept T/T, L/C, D/P, and Western Union. For standard orders, full payment is required before shipment; for bulk projects, a 30% deposit + 70% balance before delivery is also negotiable.

Q:What is the main function of this sound insulation felt?

It works by combining high mass density with damping performance, effectively blocking airborne noise (speech, traffic) and reducing structure-borne vibration/impact noise, especially at mid-low frequencies.

Q:How do I choose the right thickness?

1.2mm (23dB): For light noise reduction, partition walls, ceilings. 2.0mm (27-29dB): For home theaters, KTV, bedrooms. 3.0mm (30-32dB): For industrial equipment, pipes, and high-noise environments.
