WITSON applies quality-control procedures across different stages of the manufacturing process, from supplier and incoming-material management to production inspection, finished-product testing, packaging checks and reliability testing.
The WITSON quality-control process is organized around four major stages: Vendor Quality Management, Incoming Quality Control, In-Process Quality Control, and Final & Outgoing Quality Control.
01 Vendor Quality Management → Supplier management and evaluation
02 Incoming Quality Control → 100% QC inspection of incoming materials
03 In-Process Quality Control → Production, semi-finished product and SPC control
04 Final & Outgoing Quality Control → 100% finished-goods QC, burning test and reliability testing
WITSON applies standardized management procedures to material suppliers and conducts regular visits to supplier production workshops.
Suppliers that do not meet the required quality standards may be eliminated from the supplier system. WITSON also continues to develop and evaluate new material suppliers to support the supply chain and quality requirements.
WITSON performs 100% QC inspection on incoming materials. Materials that do not meet quality requirements are returned to suppliers for replacement, helping prevent defective materials from entering the production process.
If defective materials are identified during production, they are separated and replacement work is arranged. Relevant material replacement records are maintained to help trace the cause and reduce the possibility of similar failures occurring again.
Production processes are prepared in advance for different product models. Processes requiring additional attention are specifically identified to help reduce production mistakes.
Production processes and work positions are subject to inspection during mass production to help maintain a smooth and controlled manufacturing process.
WITSON maintains a dedicated semi-finished product quality-control and inspection process as part of in-process quality management.
SPC (Statistical Process Control) management is also incorporated into WITSON's in-process quality-control system.
WITSON performs 100% QC inspection on finished goods. According to the current quality-control process, each machine undergoes a 4–6 hour burning test before completing the outgoing quality-control process.
Accessories are subject to specialized packaging checks. Goods entering and leaving the warehouse are registered as part of WITSON's warehouse management process.
Reliability testing includes procedures such as high-temperature testing and vibration testing.
✓ Standardized material supplier management
✓ 100% QC inspection of incoming materials
✓ Defective material isolation, replacement and tracking
✓ Model-specific production-process preparation
✓ Semi-finished product quality inspection
✓ SPC (Statistical Process Control) management
✓ 100% finished-goods QC inspection
✓ 4–6 hour burning test for each machine
✓ Packaging and warehouse checks
✓ High-temperature and vibration reliability testing
WITSON's quality-control process begins before components enter production and continues through manufacturing, semi-finished product inspection, finished-product testing, packaging and warehouse management.
By combining supplier management, incoming inspection, production-process control, SPC management, finished-goods inspection and reliability testing, WITSON works to identify quality issues at different stages rather than relying only on a final check.
Yes. According to WITSON's current quality-control process, 100% QC inspection is performed on incoming materials. Materials that do not meet quality requirements are returned to suppliers for replacement.
Defective materials identified during production are separated and replaced. Relevant replacement records are also maintained to help trace the cause and reduce the possibility of similar failures occurring again.
Yes. WITSON applies In-Process Quality Control, including production-process inspection, work-position inspection, semi-finished product quality control and SPC management.
Yes. The quality-control process specifies 100% QC inspection of finished goods before completion of the outgoing quality-control process.
According to the current quality-control process, each machine undergoes a 4–6 hour burning test as part of finished-product quality control.
The quality-control information specifically identifies reliability tests including high-temperature testing and vibration testing.
WITSON integrates quality control throughout supplier management, incoming inspection, production, finished-product testing, packaging and reliability testing to support consistent quality in car multimedia and automotive electronics manufacturing.
