JOWAY Factory Quality Control Flow Chart
IQC Incoming Material Inspection: Ensure the raw materials provided by the supplier meet the quality standards
IPQC Process Quality Control: Ensure the quality of the production process meets the standards
QC Quality Control: Analysis, improvement and control of defective products after quality problems are found
QA Quality Assurance: Ensure all operations and processes comply with standards to guarantee product quality
OQC Quality Inspection: Finished product inspection to ensure that the quality is qualified before shipment
3 Selection and Control of Core Components
1) Battery Cell Solution
The main components of a power bank include battery cells, PCBA, and shell. The core components are battery cells and PCBA to make sure that the battery cells comply with the battery cell control standard UN38.3 air transport certification, and PCBA adopts the mature solution of listed companies. Joway collaborates with top-tier battery cell manufacturers, continuously develops new solutions, and ensures safety & reliability through continuous testing and verification to meet the market’s product update and iteration needs.
2) Core Component Inspection Process
Focus on the quality inspection of core components, PCBA, and battery cell inspection, whether it is equipped with some advanced inspection equipment.
- AOI optical inspection instrument/X-RAY inspection equipment/SPI solder paste inspection instrument for SMT
- Battery impact tester, temperature control short circuit tester, thermal abuse tester, battery crush tester, altitude simulation test chamber, etc.
- Comprehensive testers for the assembly process, etc.
4 Standardized Production Process Control
Pay attention to the standardization of the production process of power bank, such as SMT, soldering, assembly, aging, and packaging. As well as work standards and operator proficiency for critical positions, including functional testing post-assembly and pre-packaging. It is worth mentioning that Joway performs a full functional inspection after assembling and also conducts 100% aging tests using automated aging racks prior to packaging.
5 After-sales Service and Quality Improvement
1) Product After-Sales Support
Product after-sales service is crucial. It is necessary to consider whether the factory has a professional after-sales team, including being able to promptly resolve product anomalies, as well as regularly collecting market feedback and following up in a timely manner.
2) Quality Analysis and Improvement
With professional quality management and analysis tools, for example, Lean Six Sigma Management.
Joway adopts five quality analysis tools (PPAP/APQP/FMEA/MSA/SPC) to improve product quality through quality analysis. We continuously optimize product quality and improve after-sales service level.
Joway has focused on power bank manufacturing for more than 20 years with an 80+ professional R&D team with product innovation capabilities. It has introduced advanced R&D, production, and equipment from global sources and also maintains a dedicated automation engineering team. It supports OEM/ODM/gift customization.
