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 Chain Sprocket?
A:
A Chain Sprocket is a profiled wheel with teeth designed to mesh with the links of a roller chain, timing belt, or other perforated material. It is a critical power transmission component that converts rotational motion and torque between shafts via a chain drive system.
Q:What types of sprockets do you manufacture?
A:
We produce Roller Chain Sprockets (ANSI/ISO), Taper Lock Sprockets, Finished Bore Sprockets, Double-Pitch Sprockets, Idler Sprockets, Single & Double Strand Sprockets, and Custom & OEM Sprockets.
Q:How do I specify the correct sprocket?
A:
You need to know five key parameters: Chain Type & Pitch, Number of Teeth (N), Bore Size & Type, Hub Configuration (Type A, B, or C), and Material & Finish.
Q:What materials are your sprockets made from?
A:
We use Carbon Steel (SS400, S45C), Stainless Steel (304, 316), Cast Iron (GGG40), and Plastic/Nylon (MC Nylon, POM) depending on application, load, and environment.
Q:How do I calculate the speed ratio between two sprockets?
A:
The Speed Ratio equals the number of teeth on the driven sprocket divided by the number of teeth on the driver sprocket. Formula: Ratio = N_driven / N_driver.
