AI-Powered supplier vetting

SummaryThe supplier focuses on the design, manufacturing, sales, and technical support of UHV pump stations and casting pouring riser separators. It reports own factories, CNC and testing equipment, ISO9001:2015 certification, ERP-based management, and standardized finished-product inspection. Customization and ODM services are available, but no new product was developed in the past year. Service governance is weakly documented: procedures exist without records for service capability assessment, while corrective-action and complaint-handling procedures or records are absent. The supplier has inventory capacity and self-operated import/export rights, but no valid manufacturing-capacity contract with its related subcontractor, overseas warehouse, overseas showroom, overseas agents, or branches. Export sales represent 1%–10% of total sales. Financial information is insufficient for assessment and is excluded from this analysis.

Supplier typeThe supplier describes itself as an industrial manufacturer focused on UHV pump stations and casting pouring riser separators, with own factories and modern machining, measurement, and testing equipment. This supports classification as a manufacturing-oriented supplier rather than a pure trader.

CertificationsThe supplier reports an ISO9001:2015 certificate and states that it operates an ISO9001 quality management system and ERP management. However, no additional certification or factory environmental impact assessment report is provided.

After-Sales capabilityThe supplier has inventory service capacity and has participated in an offline trade show, but it lacks written procedures or records for corrective and preventive actions and customer complaint handling. It also has no overseas warehouse, overseas showroom, overseas agents, or branches, limiting documented after-sales infrastructure.

Production capacityOwn factories, CNC milling, three-dimensional and testing equipment, inventory capacity, export rights, and uniformly followed finished-product inspection instructions indicate established production and fulfillment capabilities. However, there is no valid manufacturing-capacity contract with a related subcontractor, and overseas operational capacity is absent.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization, and also provides ODM services. These statements directly support broad customization capability.

Product Q&A

Q:What is your minimum order quantity?

1 piece for samples, 50-100 pcs for bulk, depending on specifications.

Q:What is the difference between 304 and 316L?

304 is weakly magnetic with good corrosion resistance; 316L is fully non-magnetic with superior corrosion resistance (molybdenum added), suitable for more demanding vacuum environments.

Q:Can you customize by our drawings?

Vacuum aluminized (silver gloss), vacuum gold plated (gold), vacuum aluminized diffused (surface hardened), PTFE coated (anti-stick, anti-corrosion), natural (stainless steel original color). Custom treatments also available.

Q:What is the lead time?

Samples: 7-15 days. Standard bulk: 15-30 days. Custom: 30-60 days.
