Yes, you can arrange a third-party factory audit for our accessory production line. We support full on-site evaluations by external inspection agencies to verify our manufacturing standards, quality control systems, and processing capabilities for high-pressure cleaning machine accessories, ensuring complete transparency before mass production begins.
Our manufacturing facility implements a strict quality inspection system across all assembly and processing lines. When a third-party audit agency—such as SGS, TÜV, or Intertek—visits the plant, they are granted access to our hardware fabrication areas, mold development equipment, and testing laboratories. This process allows auditors to verify our independent research and development capabilities, which focus on structural design, material optimization, and mechanical testing.
During the audit, technical inspectors can examine our dedicated testing setups for corrosion resistance, pressure resistance, and aging. For example, our 18Mpa extension lance, constructed from plastic and stainless steel, undergoes rigorous quality checks to withstand high-pressure environments. Our past experience includes successfully serving local American car washing accessory distributors, such as our cooperation in the America brug high pressure gun project, where our adherence to strict manufacturing standards resulted in high customer repurchase rates.
To help procurement partners prepare for a facility evaluation, the table below outlines the key parameters, standards, and production capacities verified during our standard inspection processes.
| Inspection Dimension | Factory Standard / Capability | Audit Verification Method |
|---|---|---|
| Core Product Specifications | Extension lance (Plastic/Stainless Steel, 18Mpa pressure rating) | Physical measurement, pressure tolerance testing, material certification review |
| Quality Control Protocol | Full inspection (100% of finished units) | Review of QC logs, testing equipment calibration records, and defect rates |
| Production Capacity | Monthly output exceeding 150,000 pieces/sets | On-site line speed observation, equipment count, and shift log analysis |
| After-Sales Support | Responsible for all quality problems within 3 months | Review of service procedures, warranty terms, and client feedback files |
