Process 7. Function Testing

Key Processes:

Performing various functional tests on the assembled juicer, including start/stop, speed adjustment, safety interlock, noise level, etc.

Main Equipment:

Noise Meter, Power Meter, Simulated Load Testing Equipment.

Common Issues:

Failure to start/stop, abnormal speed adjustment, safety interlock failure, excessive noise, excessive vibration, button failure/abnormal indicator lights.

Process 8. Safety & Performance Testing

Key Processes:

Conducting electrical safety tests (e.g., insulation withstand voltage, grounding resistance, leakage current) and performance tests (e.g., juicing efficiency, juice yield, motor temperature rise) to ensure the product meets relevant standards.

Main Equipment:

Withstand Voltage Tester, Grounding Resistance Tester, Leakage Current Tester, Juicing Efficiency Test Bench.

Common Issues:

Substandard insulation resistance, poor grounding, excessive leakage current, withstand voltage test failure, low juicing efficiency, low juice yield, excessive motor temperature rise, inaccurate test results.

Process 9. Appearance Check, Cleaning & Packaging

Key Processes:

Final inspection of product appearance to ensure no scratches, stains, or other defects; cleaning, then packaging according to specifications, labeling, and preparing for warehousing or shipment.

Main Equipment:

Inspection Fixtures, Cleaning Equipment, Packaging Machine, Carton Sealing Machine.

Common Issues:

Appearance defects, incomplete cleaning, incorrect/missing labels, missing/incorrect accessories, packaging damage, insufficient anti-shock measures.

7. How V-Trust Controls Juicer Quality

V-Trust delivers comprehensive juicer inspection services, ensuring consistent product quality and regulatory compliance. Our quality control solutions cover all stages of juicer production, including Sample Checks, Production Monitoring, During Production Inspection, Pre-Shipment Inspection, and Container Loading Supervision, reducing the risk of product failures and costly recalls.

Sample Check

Before mass production, our engineers meticulously evaluate juicer samples for design accuracy, material quality, and initial functionality. This includes checking motor power, pulp extraction efficiency, ease of cleaning, and overall build quality to ensure the sample meets all specified requirements.

Production Monitoring

During juicer production, V-Trust provides on-site monitoring to track assembly quality, motor installation, and component integration. We watch for issues like incorrect wiring, loose fittings, or inconsistent housing assembly, allowing for immediate corrective actions to maintain production standards.

During Production Inspection (DPI)

When at least 10% of the juicer order is completed, we conduct a DPI. This inspection focuses on early-stage issues such as proper motor housing assembly, blade alignment, control panel functionality, and potential leakage points, helping to prevent widespread defects.

Pre-Shipment Inspection (PSI)

A thorough final inspection is performed when juicer production is 80-100% finished and packed. This includes comprehensive checks on:

• Overall product quality, functionality (e.g., motor speed, noise level, juice yield)
• Electrical safety and power cord integrity
• Component fit, finish, and absence of cosmetic defects
• Correct quantity, packaging integrity, and labeling accuracy

Container Loading Supervision (CLS)

We supervise the loading of juicers into containers to ensure proper stacking, protection, and quantity verification. This prevents damage during transit, confirms correct product count, and ensures packaging is suitable for international shipping.
