AI-Powered supplier vetting
SummaryWeifang Shengao Machinery Co., Ltd. is a limited company focused on mechanical parts, hardware, metal tools, CNC machine tools, and related components. It identifies as a professional technical supplier and offers 3D software design and broad customization services, including sample-, design-, full-, minor-, and flexible customization. The supplier has written procedures and records for service assessment, corrective actions, and complaint handling. Its export sales share is stated at 71%–90%, with three years of export experience. However, the supplier has nine employees, only two years of total R&D engineer experience, no new products in the past year, no ODM, SDK, or overseas service infrastructure, and no stated customer cases. Audit information is provided for a TUV Rheinland audit with a validity period from September 4, 2025 to September 3, 2026, but the evaluation result is recorded as 0 and no certification name is specified.
Supplier typeThe supplier explicitly identifies as a professional technical supplier and a limited company. Its stated business and product scope covers mechanical parts, hardware products, metal tools, CNC machine tools, functional components, forgings, and powder metallurgy products; the audit record identifies mechanical parts as the primary product.
After-Sales capabilityThe supplier has clear written procedures and followed records for corrective and preventive actions and for handling customer complaints. This directly supports an established service-response process, although the slices do not provide service performance results or response-time data.
Production capacityThe supplier reports an annual production output range, six to ten quality-control staff, on-time delivery, random production quality inspection, and its own factory. It has nine total employees, so the available evidence supports an operating production capability, while capacity beyond the stated output range cannot be determined.
Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization, and also welcomes OEM and ODM requests according to its company description. These repeated statements provide direct evidence of broad customization coverage, although the separate record states that ODM is not available, creating a conflict on ODM specifically.
Product Q&A
Q:What is a dovetail groove torsion lock, and how does it work?
A:
It is a specialized locking device for securing stacked shipping containers. The dovetail groove allows the lock to slide easily into the container's corner casting and twist (torsion) into a locked position, creating a rigid connection that prevents unintended separation.
Q:What materials is it made from?
A:
Our locks are primarily constructed from high-tensile forged steel for maximum strength. They feature a durable anti-corrosion coating (such as hot-dip galvanization or zinc plating) to withstand harsh marine and industrial environments.
Q:Is it compatible with all standard containers?
A:
Yes. The lock is designed to fit ISO standard container corner castings, making it compatible with most common 20ft, 40ft, and high-cube containers used in global shipping.
Q:Do I need special tools to operate it?
A:
No. The design prioritizes manual operation. The dovetail groove allows for easy placement and the torsion bar can typically be engaged and disengaged by hand or with minimal, standard leverage tools in some high-capacity models.
Q:What is its load capacity or Safe Working Load (SWL)?
A:
The exact SWL varies by model. Please refer to the product's technical datasheet or consult our sales team for specific load ratings. All locks are rigorously tested to exceed standard safety requirements.
