Ensuring Consistent Quality from Raw Materials to Finished Products
At Xiamen Qianyu Technology, quality is the foundation of everything we manufacture. Our dedicated Quality Control (QC) Team and Testing Laboratory monitor every stage of production-from raw material inspection to final product verification-to ensure that every cleanroom consumable meets international quality standards.
By implementing strict inspection procedures and advanced testing methods, we deliver reliable products that support contamination control in semiconductor, electronics, pharmaceutical, medical, and precision manufacturing industries.
Our Quality Commitment
We believe that consistent quality begins with a controlled manufacturing process.
Our quality management system focuses on:
- Incoming raw material inspection
- In-process production monitoring
- Finished product performance testing
- Batch traceability
- Continuous process improvement
- Customer-specific quality requirements
Every production batch is carefully inspected before shipment to ensure stable performance and product consistency.
Our Testing Laboratory
Our in-house testing laboratory is equipped to evaluate the critical performance characteristics of cleanroom consumables and ESD products.
The laboratory supports:
- Material performance verification
- Product cleanliness evaluation
- Physical property testing
- ESD performance testing
- Packaging inspection
- Production validation
This comprehensive testing process helps guarantee product reliability for demanding cleanroom environments.
Quality Control Process
Step 1 – Incoming Material Inspection
Before production begins, all raw materials are inspected to verify:
- Material specifications
- Surface appearance
- Dimensions
- Fabric weight (GSM)
- Color consistency
- Supplier compliance
Only qualified materials are released for manufacturing.
Step 2 – In-Process Quality Inspection
During production, our QC technicians continuously monitor:
- Cutting accuracy
- Edge sealing quality
- Stitching quality (ESD garments)
- Cleanliness of production environment
- Packaging process
- Product dimensions
Regular inspections help prevent defects before products reach the final stage.
Step 3 – Finished Product Testing
Every finished batch undergoes comprehensive testing before shipment.
Typical inspections include:
- Visual inspection
- Dimension verification
- Packaging inspection
- Product labeling verification
- Sampling inspection
- Batch documentation
Only products that meet our quality requirements are approved for delivery.
Testing Capabilities
Particle Count Test
Measures the number of particles released from cleanroom wipes to ensure suitability for controlled environments.
Absorbency Test
Evaluates liquid absorption capacity and absorption speed to verify cleaning efficiency.
Ionic Contamination Test
Analyzes residual ionic contaminants.Low ionic contamination helps reduce the risk of sensitive component damage.
Non-Volatile Residue (NVR) Test
Measures non-volatile residues remaining after solvent evaporation to verify product cleanliness.
Fiber & Lint Release Test
Evaluates lint generation during wiping operations to ensure low particle contamination.
ESD Performance Test
For ESD garments and accessories, we verify:Surface resistance,Electrical conductivity to ensures reliable electrostatic protection in ESD-controlled environments.
Tensile Strength Test
Measures product durability under mechanical stress to ensure consistent performance during use.
Dimension & Weight Verification
Each production batch is checked for:
Size,Thickness,Fabric weight,Tolerance compliance.
