AI-Powered supplier vetting

SummaryQingdao Vanhon Machinery Technology Co., Ltd. is identified as a trading company and limited company offering vehicle lifts, simple parking lifts, lift accessories, and hardware accessories. It reports OEM service for popular brands, broad customization options, inventory capability, and substantial export orientation, with Europe and North America listed as primary markets. However, the supplier has only four employees and one R&D engineer, launched no new products in the previous year, has no available SDK, and holds no stated management-system certifications. Quality-control evidence is weak: test equipment is reported as zero, while quality assurance and traceability statuses are unknown. Written procedures are absent for corrective actions and complaint handling. Financial records are referenced for three years, but no financial results are provided. No specific customer cases are disclosed, although OEM service for well-known brands is explicitly claimed.

CertificationsThe supplier’s certification of management systems is explicitly recorded as “NIL.” No certification is identified in the provided information, so there is no evidence of certification-based compliance strength.

After-Sales capabilityThe supplier has inventory service capability and accepts multiple payment methods, but it has no written procedures or records for corrective and preventive actions or effective customer-complaint handling. Its service-capability assessment has relevant records but no written procedure, and it has no overseas warehouse or showroom.

R&D capabilityThe supplier reports one R&D engineer with one year of total R&D experience, launched no new products during the previous year, and has no available SDK. These explicit indicators show limited demonstrated innovation activity, although design and customization services are available.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. This is direct evidence of broad customization service coverage.

Product Q&A

Q:Q1: What is the function of a spring lock washer?

Spring lock washers provide continuous spring tension and friction resistance, effectively preventing bolts and nuts from loosening caused by vibration, shock and thermal expansion.

Q:Q2: What is the difference between DIN127A and DIN127B?

DIN127A is standard light type for general use. DIN127B is heavy-duty thicker type with stronger spring force, suitable for high-vibration and heavy-load working conditions.

Q:Q3: What is DIN7980 spring washer used for?

DIN7980 is specially designed for cylindrical socket head cap screws, with smaller outer diameter, widely used in molds, precision machinery and compact assembly.

Q:Q4: What standards do your spring washers support?

We support DIN, ISO, ANSI/ASME, JIS and GB standards, including DIN127, DIN7980, ISO8752, ASME B18.21.1 and JIS B1251.

Q:Q5: What materials are available for spring washers?

Carbon steel, stainless steel 304/316, alloy steel, phosphor bronze and beryllium copper for different environment requirements.
