AI-Powered supplier vetting

SummaryThe supplier demonstrates established manufacturing and quality-control processes, including ISO 9001:2015 certification, CE product compliance, raw-material traceability, and 100% finished-product inspection. It offers OEM, ODM, and sample-based flexible customization, with stated peak-season lead times of one month and off-season lead times within 15 working days. However, innovation evidence is limited: no new products were launched in the past year, the supplier is not identified as a professional technical supplier, and it has no 3D design or SDK capability. Service-system documentation is incomplete because several procedures lack written records or formal approval details. The supplier has no stated inventory, overseas warehouse, overseas branch, showroom, or trade-show capability. Customer-case evidence is also limited, with no Fortune 500 collaboration reported and no repeat-buyer preference recorded.

Supplier typeThe supplier is a manufacturing-oriented producer with drawing and rewinding facilities, offering OEM and ODM services. It is explicitly not classified as a professional technical supplier and does not provide 3D software design services.

CertificationsThe supplier holds an ISO 9001:2015 management-system certificate and reports CE product compliance. These certifications provide explicit evidence of formal quality-management and product-compliance credentials.

After-Sales capabilityThe supplier has procedures for corrective and preventive action and customer complaints, but no written records are maintained. It also lacks inventory, overseas warehouses, overseas branches or agents, overseas showrooms, and participation in offline trade shows, limiting documented and international after-sales support.

R&D capabilityThe supplier has two R&D engineers and offers ODM services, but reports no new products in the past year, no SDK availability, no 3D software design service, and no professional technical-supplier R&D capability. The evidence indicates limited recent innovation capacity.

Production capacityThe supplier has drawing and rewinding facilities, supports specified product sizes, performs 100% finished-product inspection, and reports lead times of one month in peak season and within 15 working days off-season. However, it reports no in-stock capacity and lacks a valid manufacturing-capacity contract with associated subcontractors.

Customization capabilityThe supplier explicitly provides customization from samples and flexible customization, can produce customer-specified sizes, and offers both OEM and ODM services. These statements directly support a broad customization capability.

Client casesThe supplier reports that 51%–70% of total sales come from exports, but also states only domestic exporting experience, no Fortune 500 collaboration, and a repeat-buyer preference value of zero. The available evidence does not establish strong or notable customer cases.

Product Q&A

Q:What is the material composition of the seal tape?

The tape is made of 100% PTFE (Polytetrafluoroethylene) without oil, providing excellent chemical inertia and corrosion resistance.

Q:What are the temperature resistance limits?

The PTFE thread seal tape can withstand temperatures from -190 Degree Centigrade (Cold Resistance) to +370 Degree Centigrade (Heat Resistance).

Q:What is the minimum order quantity (MOQ)?

The standard MOQ is 50,000 pcs. However, we accept small orders and welcome OEM requests.

Q:What are the payment terms and delivery time?

Payment terms include LC, T/T, and D/P. Delivery time is typically 15-30 days after receiving the deposit or L/C, depending on the season.

Q:How should the PTFE thread seal tape be applied?

Wrap the tape counterclockwise around the male thread while tightening it firmly. Usually, more than ten wraps are recommended to ensure a leak-proof seal without over-tightening the joint.
