AI-Powered supplier vetting
SummaryNingbo Furui Machine Co., Ltd. is a China-based limited trading company established in 2021 with 10 employees and a valid import/export license. The supplier reports OEM service for well-known brands, ODM service, recent new-product activity, and broad customization options. Production information lists substantial output for gears, bushings, brackets, stainless steel screws, and shaft pins, although the supplier’s manufacturing structure is not fully clear because it is identified as a trading company. After-sales support is described as responsive, but service procedures and corrective-action mechanisms lack written records. Financial information is limited to year references, without sufficient evidence to assess credibility. The supplier has no stated stock, overseas warehouse, showroom, agent, or branch capability, and raw-material traceability status is unknown.
Supplier typeThe supplier is identified as a limited company and trading company established in 2021 in Ningbo, China, with 10 employees and a stated factory location. Its valid import/export license supports trading and export operations, but the available information does not clearly establish the extent of its own manufacturing operations.
CertificationsThe supplier reports holding a valid import/export license. No other certifications or quality-management credentials are provided, so certification coverage beyond export authorization cannot be assessed.
After-Sales capabilityThe supplier states that it provides prompt after-sales support, technical assistance, and timely issue resolution. However, service assessment procedures and corrective/preventive-action mechanisms have procedures but no written records, and there are no overseas warehouses, showrooms, agents, or branches.
R&D capabilityThe supplier reports new products during the past year, ODM availability, and R&D responsibilities covering new-product development, process formulation, technical improvement, and technical support. However, total R&D engineer experience is listed as only 1, and no SDK is available, indicating some limitations in documented development resources.
Production capacityAnnual output is specified for five product categories, including gears, bushings, brackets, stainless steel screws, and shaft pins, and the supplier reports a one-month off-season lead time. Nevertheless, the supplier has no in-stock capability, and the distinction between its trading-company status and factory capacity is not fully documented.
Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also reports ODM service, providing direct evidence of broad customization support.
Client casesThe supplier states that it provides OEM services for well-known brands. No customer names, project details, order references, or independently verifiable case information are supplied, so the breadth and credibility of its customer portfolio cannot be fully assessed.
Product Q&A
Q:What are laminated neodymium magnets?
A:
Laminated neodymium magnets are composed of multiple thin NdFeB slices bonded together with high-temperature insulating glue. Each slice is electrically isolated to block eddy current loops, specially designed for high-speed alternating magnetic field motors.
Q:What is the difference between solid NdFeB and laminated NdFeB magnets?
A:
Solid monolithic magnets produce huge eddy currents and severe heat under high rotation speed, easy to suffer irreversible demagnetization.
Laminated magnets cut eddy loss by 60% to 90%, much lower temperature rise, higher motor efficiency and longer service life. The only downside is higher processing cost.
Q:How thin can you make each magnet slice?
A:
Standard slice thickness range: 0.5mm ~ 3.0mm. Thinner slices bring better eddy suppression effect, but higher production difficulty and cost. We support customized thickness as customer requirements.
Q:How thick is the insulation layer between slices?
A:
Our insulation glue layer is controlled within 20 and 30 microns, ultra-thin to avoid wasting magnetic space while maintaining stable insulation resistance.
Q:Will laminated magnets delaminate or separate under high-speed rotation?
A:
No. We adopt high-pressure hot curing process with high shear strength insulating adhesive. After integrated outer circle precision grinding, the whole magnet assembly has excellent structural stability, no delamination under long-time high-speed operation and temperature cycling.
