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 Cold Heading Die?
A:
A cold heading die is a high-precision tool, typically made from hardened tool steel or tungsten carbide, used in the cold heading process to shape metal wire into complex parts like bolts and screws under extreme pressure.
Q:What are the Main Types of Cold Heading Dies?
A:
Main types include Solid Dies for simple shapes, Insert Dies (Cased Dies) for wear-prone areas, Multi-Station Dies for progressive forming, Knockout Pin Dies for ejection, and Compound Dies combining multiple operations.
Q:What Materials are Used for Cold Heading Dies?
A:
Common materials are Tool Steels (HSS like M2, M4) for toughness, Tungsten Carbide for superior wear resistance in high-volume production, and Ceramics & Cermets for specialized extreme wear applications.
Q:What are the Common Failure Modes of Cold Heading Dies?
A:
Common failures include Wear (Abrasion), Fatigue Cracking from cyclic loading, Chipping or Brittle Fracture due to impact, Gallings/Adhesive Wear, and Plastic Deformation under extreme pressure.
Q:How Can I Extend the Life of My Cold Heading Dies?
A:
Extend life by selecting proper materials, optimizing die design with smooth radii, ensuring precise heat treatment, applying coatings like TiN or DLC, maintaining alignment, and using adequate lubrication.
