MULIN G.
China Electronics & Industrial Inspector | Factory Auditor
Are you experiencing inconsistent quality from your Chinese suppliers? One batch is good, but the next batch is different. The defect rate suddenly increases during mass production. The supplier says everything meets the requirements, but the products you receive don't actually match your specifications. Or sometimes, the real problem starts even earlier — the supplier simply didn't fully understand what you needed. These are common problems when working with manufacturers remotely. I am an independent China-based Product Inspector and Factory Auditor, specializing in electronics, electronic manufacturing, and industrial products. What makes my inspection service different is my engineering background. I have 10+ years of experience in electronics and industrial fields, including 8 years as a hardware systems engineer. I understand not only how to inspect a finished product, but also how engineering requirements are translated into manufacturing, how Chinese factories operate, and where quality problems can occur throughout the process. I can help you with: Pre-Shipment Inspection (PSI) Product & Sample Inspection Factory Audit & Supplier Verification Incoming Material / Component Inspection Production & Quality Process Assessment Specification, Function & Workmanship Checks Defect and Quality Risk Identification Supplier Communication & Corrective Action Follow-Up For electronics and industrial products, inspection often requires more than checking appearance, quantity, and packaging. I can review your specifications from an engineering perspective, understand what the product is supposed to do, communicate technical requirements clearly with the factory, and verify whether the actual product meets those requirements. When a problem is found, I don't just report “Pass” or “Fail.” I can help identify where the deviation comes from, communicate it with the supplier, and follow up on corrective actions. My role is independent and client-side. I represent your requirements during the inspection and provide transparent findings based on what I actually see and test on site. Focus Areas: Electronics | PCB/PCBA | Electronic Components | Industrial Electronics | Test & Measurement | Sensors & Instrumentation | Industrial Automation | Electrical & Electromechanical Products If you manufacture or source electronic or industrial products in China and need someone on the ground who can understand both your engineering requirements and the factory's manufacturing process, feel free to contact me.
