AI-Powered supplier vetting

SummaryThe supplier demonstrates broad customization and 3D software design capability, supported by five production lines, stated ongoing batch quantity reconciliation, and raw-material traceability. It reports quality assurance, six to ten quality-control staff, in-stock capacity, and lead times within 15 working days in both peak and off-season periods. However, it is explicitly not classified as a professional technical supplier, lacks written corrective-action and complaint-handling procedures, and finished products are checked by packing staff. No overseas agents, branches, warehouse, showroom, or offline trade-show participation are reported. Manufacturing subcontracting lacks a valid contract and standard operating procedure. Financial evidence is limited and indicates no operating revenue in the earlier reported year; monetary figures are omitted here for privacy.

Supplier typeThe supplier is explicitly identified as not being a professional technical supplier, although it provides 3D software design services. Its stated profile emphasizes 15 years of focus and responsibility, but the provided information does not establish a different formal supplier classification.

After-Sales capabilityThe supplier states that it provides installation guidance, tension adjustment, misalignment troubleshooting, remote assistance, and checklists. However, it has no written procedures or records for corrective and preventive actions or effective complaint handling, and it has no overseas agents or branches; therefore, service capability is demonstrated but its formal and international support infrastructure is weak.

R&D capabilityThe supplier provides 3D software design services and supports customization from customer designs, while its description claims drawing-to-solution response within 24 hours and technical troubleshooting support. Nevertheless, total experienced R&D engineer experience is stated as two, and the supplier is explicitly not a professional technical supplier.

Production capacityProduction resources include five production lines and multiple listed processing machines, with in-stock capacity and stated lead times within 15 working days in both peak and off-season periods. Batch quantity reconciliation is performed continuously, but subcontracting lacks a valid contract and standard operating procedure, and finished products are checked by packing staff.

Customization capabilityThe supplier explicitly offers flexible, full, minor, and design-based customization, as well as 3D software design services. Its stated customization scope includes width, thickness, holes, cleats, guides, and seamless endless configurations, supported by technical guidance.

Product Q&A

Q:How to choose the correct synchronous pulley size for my synchronous belt?

Choose the size based on 3 key factors: Match the pulley tooth profile with the belt (e.g., trapezoidal, arc) to avoid tooth skipping. Determine the number of teeth by speed ratio and torque (follow the minimum number recommended by the manufacturer). Ensure the outer diameter (determined by teeth and pitch) and bore size match the shaft; use an adapter sleeve if needed.

Q:What materials are synchronous pulleys usually made of, and how to choose them?

Common materials and selection: Aluminum alloy: Light, heat-dissipating, cost-effective, for high-speed, low-noise equipment (e.g., 3D printers). Steel: High-strength, wear-resistant, for heavy-load equipment; carbon steel needs anti-corrosion treatment, stainless steel for humid/corrosive environments. Plastic: Low-noise, low-cost, for light-load, low-speed appliances (not for high temperature/load).

Q:What are the common problems of synchronous pulleys during use, and how to troubleshoot them?

Common problems and troubleshooting: Tooth wear/damage: Caused by overload/mismatch; replace pulley and clean. Shaft slipping: Tighten set screws, replace worn keys or reprocess bore/shaft. Abnormal noise: Correct alignment, adjust tension, replace worn pulley if needed. Deformation: Replace pulley and avoid extreme operating conditions.

Q:What is the difference between a timing pulley and a V-belt pulley, and which one should I choose?

Differences and selection: Synchronous pulleys: Tooth meshing, no slipping, high accuracy (for precision equipment); V-belt pulleys: Friction-driven, low accuracy (for general power). Synchronous: High-speed, medium-heavy load, low noise, low maintenance; V-belt: Low-speed, heavy load, more noise, frequent maintenance.

Q:What is the warranty period and after-sales service?

We provide a 1-year warranty and offer 24-hour service support for timely assistance.
