How We Mitigate Your Risk
1. Incoming QC (IQC)
Every batch of stainless steel (SS304/316) or borosilicate glass is tested for purity before production begins.
2. In-Process QC
On-site inspectors check the first-off samples and monitor the assembly line every 2 hours.
3. Final Pre-shipment
AQL 2.5/4.0 standards applied. We simulate shipping conditions to ensure packaging survives the journey.
