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 Milling/Lathe Machined Cylinder Head?

A Cylinder Head seals the top of engine cylinders. We use precision CNC processes to manufacture new heads, recondition used heads, or perform modifications like resurfacing, machining valve seats, and porting.

Q:What are your lead times?

New Head Machining takes 40-60 days. Reconditioning takes 15-25 working days. Performance modifications take 20-30 working days. Samples lead time is quoted per project.

Q:What materials are the heads made from?

We use industry-standard materials including Cast Iron (Durable/Cost-effective), Aluminum Alloy (A356-T6, 319), and Special Alloys for high-performance applications.

Q:What is included in a 'complete, ready-to-install' cylinder head?

Includes fully machined casting, new valve seats/guides, surface finish to Ra spec, 3-angle valve job, pressure testing, and dimensional inspection. Valves/springs are sold separately but can be assembled upon request.

Q:What is your MOQ for new aftermarket heads?

New Aftermarket Heads: MOQ 50 pieces per part number. Machining/Reconditioning Service: MOQ 10 pieces. Performance Work: MOQ negotiable, single pieces accepted.
