FAQ
Q: 1. How do you ensure consistent product quality?
A: We implement a comprehensive quality management system covering every stage of production, including raw material inspection, in-process quality control, final product testing, and packaging inspection. Each production batch is evaluated according to established quality procedures to ensure consistent performance and reliable product quality.
Q: 2. What quality standards do your products follow?
A: Our manufacturing process follows internationally recognized quality management systems. Depending on the product, testing is conducted according to applicable industry standards and customer requirements, including particle cleanliness, absorbency, ionic contamination, ESD performance, and dimensional accuracy.
Q: 3. Do you inspect every production batch?
A: Yes. Every production batch undergoes quality inspection before shipment. Testing may include particle count, non-volatile residue (NVR), ionic contamination, absorbency, dimensions, appearance, and packaging integrity to ensure products meet our quality requirements.
Q: 4. Can you provide a Certificate of Analysis (COA)?
A: Yes. A Certificate of Analysis (COA) can be provided for selected products upon request. The COA includes key inspection results and confirms that the shipped batch meets the agreed product specifications.
Q: 5. What certifications does your company hold?
A: Our company operates under internationally recognized quality management systems, including ISO 9001 and ISO 13485. Depending on the product category, we can also provide compliance documentation such as RoHS, REACH, and other applicable certificates upon request.
Q: 6. Are your products batch traceable?
A: Yes. Each production batch is assigned a unique lot number, allowing full traceability from raw material sourcing through manufacturing, inspection, packaging, and shipment. This system supports quality consistency and efficient issue resolution if required.
Q: 7. What laboratory tests are performed on cleanroom wipes?
A: Our laboratory conducts a range of physical and cleanliness tests, including: Particle Count Non-Volatile Residue (NVR) Ionic Contamination Absorbency Tensile Strength Fabric Weight (GSM) Thickness Dimensions Surface Appearance Testing requirements can also be customized based on customer specifications.
Q: 8. Can you provide third-party test reports?
A: Yes. Third-party laboratory testing can be arranged upon customer request. We are happy to support product qualification projects and provide independent test reports when required.
Q: 9. How do you control contamination during manufacturing?
A: Our cleanroom wipes are manufactured using controlled production processes designed to minimize particles, fibers, and contaminants. Critical processes such as cutting, cleaning, inspection, and packaging are performed under controlled environmental conditions to help maintain product cleanliness.
Q: 10. Do you offer customized quality inspections?
A: Yes. We support customized inspection requirements for OEM and industrial customers. Inspection items, acceptance criteria, packaging inspections, and documentation can be tailored to meet your project specifications
