Quality Control and Assurance System | Weilong Technology
At Weilong Technology, we build our reputation on quality. It’s the bedrock of our electromechanical components’ dependability. Our quality assurance (QA) and quality control (QC) systems are meticulously applied throughout the entire production process. From the initial inspection of raw materials to the final shipment, we ensure that our solenoid，Solenoid valves, solenoid coils, and inductors perform consistently and meet customer specification applications.
Raw material quality control
We carefully examine all incoming materials—copper wire, Carbon steel housing, stainless steel case, plastics bobbin and insulation materials. We check for dimensional accuracy, material grade, and strict adherence to RoHS, REACH, and other environmental regulations.
Process electrical verification
Every solenoid coil is subjected to resistance, inductance, and insulation integrity testing. Withstand voltage testing is a critical step, guaranteeing thermal safety and a prolonged operational lifespan right from the beginning.
Precision machining and dimensional
Quality control are paramount. Key stamped and CNC machined components are subjected to rigorous tolerance control, surface finish assessment, and concentricity monitoring. This meticulous approach guarantees the stability of the electromagnetic force, resulting in smooth and dependable operation.
Standardized assembly process control is employed.
We utilize torque-controlled assembly and process inspection to ensure precise alignment and dependable movement, thereby achieving consistent performance, even in high-volume production scenarios.
100% Functional and Performance
Testing is conducted. Each solenoid valve and associated components are tested under simulated operating conditions. This includes assessments of force, stroke, response time, power consumption, leakage (valve), and duty cycle.
Final inspection and reliability
Verification are the last steps before your order leaves our facility. We always check the product's appearance and dimensions. Furthermore, we conduct sampling-based lifecycle and environmental testing. This ensures the product's long-term reliability in your specific application.
100% Functional Testing
Every single unit is thoroughly performance-verified.
ISO-compliant Quality Management System
Our certified processes guarantee consistency and ongoing improvement.
Automotive and medical-grade expertise
Our processes are tailored for the most demanding industries.
Complete component traceability
We maintain comprehensive documentation from the initial material sourcing all the way through to final shipment.
