In the global supply chain, “Quality” is a word used by many but guaranteed by few. For a brand owner, a single batch of defective products isn’t just a loss of revenue—it is a threat to your brand’s hard-earned reputation. At Yeway, we mitigate this risk through a rigorous, multi-stage Quality Control (QC) Ecosystem. We don’t just build bottles; we engineer reliability.
I. Empirical Excellence: Our Laboratory Standards
Our internal laboratory acts as the final gatekeeper. Every production run is subjected to a suite of stress tests designed to simulate years of real-world use.
1. Adhesion & Durability Testing
As detailed in our Surface Treatment Guide, every batch must pass the ISO 2409 Cross-Cut Test. We ensure that our powder coating and paints maintain a 5B rating, providing the chemical bond necessary for Dishwasher Safety.
The ISO 2409 Cross-Cut Test: We guarantee a Grade 0 adhesion rating, ensuring your powder coating is truly dishwasher safe.
2. Vacuum Integrity & Thermal Retention
Utilizing high-precision digital sensors, we conduct 12-hour and 24-hour thermal decay tests. This validates our High-Vacuum Insulation technology, ensuring that your customers experience the ice-cold or piping-hot performance promised by your marketing.
Validating thermal retention: Digital sensors monitor our high-vacuum insulation to ensure 24-hour temperature performance.
3. Corrosion Resistance (Salt Spray Test)
We subject our 304/316 stainless steel substrates to ASTM B117 Salt Spray Testing. This accelerates environmental stress to guarantee that your products will remain rust-free even in coastal or high-humidity regions.

II. The Three Pillars of On-Site Inspection
We audit every shipment of raw materials—stainless steel, seals, and paints—testing for purity and compliance before production begins.
Our QC team is embedded on the floor, inspecting every station from initial stretch-forming to the final Branding execution.
Final AQL inspections are conducted on packaged goods to ensure lid fitment, packaging integrity, and aesthetic perfection before shipment.
The Human Element
While data drives our decisions, our experienced inspectors provide the intuition. They check for the “soul” of the product—the smoothness of the lid’s click, the 100% leak-proof seal, and the visible vibrancy of the artwork. This artisanal oversight ensures that every bottle feels as premium as it looks.
Final OQC inspection: Beyond data, our artisanal oversight ensures a 100% leak-proof seal and flawless branding execution.
Quality Assurance FAQ
Q: Do you provide third-party lab testing reports (SGS/TUV)?
A: Yes, we regularly collaborate with international labs to provide FDA, LFGB, and BPA-free certifications for our global partners.
Q: How do you handle batches that fail the ISO 2409 test?
A: Failed batches are isolated and analyzed to find the root cause in the coating line. We do not compromise; only Grade 0 adhesion products proceed to packaging.
