AI-Powered supplier vetting
SummaryWeifang Jufeng Metal Products Co., Ltd. is a China-based limited company established in 2017, with inconsistent employee records of 5, 29, and quality-control staffing of 6–10. It offers metal stamping, fabrication, welding, punching, automotive, and related products, and is identified as a trading company despite describing its own-factory production capability. The supplier reports three production lines, stated output capacities across several product categories, broad export-market coverage, and port access through Qingdao, Tianjin, and Shanghai. It holds an ISO9001:2015 certificate and reports quality inspections during production. R&D evidence is positive: one year of total R&D-engineer experience is stated, new products were developed in the past year, and ODM plus multiple customization methods are available. However, there is no available SDK, no overseas showroom, no overseas agents or branches, no offline trade-show participation, and no overseas service countries reported. Financial...
CertificationsThe supplier explicitly reports holding an ISO9001:2015 certificate. This provides direct evidence of a certified quality-management system, although no certificate number, scope, or issuing body is supplied.
R&D capabilityThe supplier reports one year of total R&D-engineer experience, new products within the past year, ODM availability, and multiple customization methods. These are positive indicators of active product development, while the absence of an available SDK limits evidence for software or platform integration capability.
Production capacityThe supplier reports three production lines and category-specific capacities for mailboxes, metal fabrication parts, cabinets, stamping parts, and auto parts, alongside broad export-market coverage and access to Qingdao, Tianjin, and Shanghai ports. However, employee counts vary across records and the supplier is also classified as a trading company, so the scale and direct-manufacturing structure require verification.
Customization capabilityThe supplier explicitly offers OEM, ODM, smaller quantities, flexible customization, minor and full customization, customization from designs, and customization from samples. It also claims to provide exclusive and unique solutions, directly supporting a broad customization offering.
Product Q&A
Q:What is a Self-Locking Folding Hinge?
A:
A specialized hardware device designed to connect two panels that can be folded and unfolded smoothly. Its core feature is an integrated self-locking mechanism that automatically holds the panels securely in the fully open position without the need for additional latches or manual locking.
Q:What are the main applications of this hinge?
A:
These hinges are widely used in products requiring stable, flat surfaces in use and compact storage afterward, including folding tables, desks, space dividers, room partitions, folding platforms, stages, furniture for RVs, campers, boats, and industrial workbenches.
Q:How does the self-locking mechanism work?
A:
The mechanism typically involves a spring-loaded cam, a detent pin, or an over-center design. When the panels are opened to a specific angle, the internal components snap into a locked position, providing a positive stop and preventing accidental folding. The lock is released by lifting a lever or applying slight upward pressure.
Q:What materials are your hinges made from?
A:
We manufacture hinges from durable materials including cold-rolled steel, stamped steel, or aluminum alloy for the main body. Pivot pins and locking components are made from hardened steel or zinc alloy. Surface finishes include electroplated zinc, powder coating, or nickel plating.
Q:What sizes and load capacities are available?
A:
Our standard range includes lengths from 200mm to 1200mm and load capacities from 25kg to over 250kg per pair. Panel thickness accommodates 15mm to 40mm. Custom sizes and capacities are available for OEM orders.
