AI-Powered supplier vetting

SummaryThe supplier is a China-based manufacturer specializing in transmission and machining products, including keyless locking devices, timing belt pulleys, bushings, couplings, gears, and related parts. It holds ISO 9001 certification, reports two production lines, 6–10 quality-control staff, and stated annual outputs of 150,000 keyless locking devices and 300,000 timing belt pulleys. Export activity is substantial, with 90% of sales from exports and 11 years of exporting experience. Service procedures exist for supplier assessment and corrective actions, but some lack written records; the supplier has no overseas agents, warehouses, showrooms, inventory service, or valid manufacturing-capacity contract with affiliated subcontractors. R&D and 3D design capabilities are limited, with only minor customization and no new products reported in the past year. Financial credibility cannot be assessed because the supplied financial figures are incomplete and inconsistent; financial data is not reproduced here.

Supplier typeThe supplier is identified as not being a professional technical supplier and operates as a manufacturer of keyless locking devices, timing belt pulleys, couplings, gears, and other machining parts. Its facilities include CNC machining and turning equipment, supporting classification as a machining and mechanical-transmission product manufacturer.

CertificationsThe supplier reports holding ISO 9001 certification, and the quality-assurance information states that quality assurance is present. This provides explicit evidence of a formal quality-management certification.

After-Sales capabilityThe supplier has a clear customer-complaint procedure with follow-up records and accepts multiple quotation and payment terms. However, corrective and preventive actions lack written records, and the supplier has no overseas agents or branches, overseas warehouse, showroom, or in-stock service capability, limiting documented and localized after-sales support.

R&D capabilityThe supplier reports no professional technical R&D capability, no 3D software design service, and no new product in the past year. Although 6–10 years of total R&D-engineer experience is reported, the stated lack of recent product development indicates limited demonstrated innovation.

Production capacityThe supplier operates two production lines and reports annual output of 300,000 timing belt pulleys and 150,000 keyless locking devices, with 6–10 quality-control staff and documented finished-product inspection instructions. Capacity assurance is weakened because there is no in-stock service capability, no valid manufacturing-capacity contract with affiliated subcontractors, and peak-season lead-time data is unclear.

Customization capabilityThe supplier explicitly provides minor customization and has design-service capability limited to minor customization. This confirms some customization ability, but not broad or advanced engineering customization.

Product Q&A

Q:Which international brands are compatible with your locking devices?

Our devices are interchangeable with major brands including BIKON, Ringspann, TOLLOK, BEA, BONFIX, Challenge, Chiaravalli, CONEX, Fenlock, GERWAH, ITALBLOCK, KTR, KINLOK, MAV, POGGI, SATI, Tsubaki, Walther Flender, LoveJoy, and others.

Q:What materials are available for the locking devices?

Raw materials include Carbon Steel C45E, Carbon Steel 42CrMo4V, Stainless Steel AISI431, and Stainless Steel AISI304, allowing selection based on specific environmental and strength requirements.

Q:What are the key features of the KLD-1 series?

KLD-1 is a medium torque, non-self-centering type with medium surface pressure. It features a slotted double tapered ring design for high mounting tolerance and is the most popular type for gear wheel connections.

Q:Does the locking device require a shaft collar for positioning?

No, many models (such as KLD-2, KLD-3, and KLD-19) feature a spacer ring between the outer flange and the hub that maintains the fitting position axially, enabling exact positioning without a shaft collar.

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

The minimum order quantity is 1 piece, allowing for flexible purchasing for both small projects and large-scale production.
