process Of Design&Quality Control

process of Design
Creating glass bottles that blend artistry and functionality follows a purposeful evolution:
1. Concept Sketching
Designers begin with free-flowing sketches, exploring how form, ergonomics, and brand storytelling merge into the bottle's blueprint. Organic shapes, comfortable curves, and brand-inspired details take shape on paper, capturing the initial vision.
2. Design Refinement
Sketches mature into a polished plan. Stakeholders collaborate to balance aesthetic allure (e.g., a graceful neck, distinctive silhouette) with practical demands (e.g., efficient filling, cap compatibility), locking in the core design direction.
3. Digital Precisioning
Advanced CAD software transforms 2D concepts into detailed 3D models. Every dimension-from base thickness to shoulder slope-is fine-tuned for structural integrity and manufacturing viability.
4. Lifelike Visualization
The 3D model is rendered to simulate real-world lighting, textures, and finishes (e.g., frosted glass, metallic sheen). These realistic previews help teams visualize the final product early, speeding up decisions.
5. Tactile Prototyping
A physical prototype (via 3D printing or CNC machining) is created. This hands-on model allows testing of grip, scale, and details-uncovering subtle improvements before mass production begins.
6. Productionization
After prototype tweaks, the design enters full-scale production. Glass is molded, decorated (e.g., screen-printing, coatings), and assembled into the branded end-product-ready to captivate shelves, as seen in the "Gypsy" liquor collection.
process of quality control
Every bottle undergoes rigorous testing to meet premium standards:
1. Dimension Verification
Laser scanners or precision calipers measure key dimensions (height, diameter, neck width), ensuring label alignment, cap fit, and shelf stability.
2. Uniform Mass Check
Bottles are weighed to confirm even glass distribution-deviations signal potential structural issues or manufacturing flaws.
3. Capacity Confirmation
Filling with liquid verifies the bottle holds its labeled volume-a must for regulatory compliance and consumer trust.
4. Graphic Bond Test
Tape is applied to printed areas and peeled off. Any peeling indicates weak adhesion, risking brand damage.
5. Scratch Endurance Test
A sharp tool simulates abrasion (e.g., warehouse handling) to test if paints or coatings resist scratching.
6. Coating Grip Test
Tape pressed onto spray-coated surfaces is removed-lifting signals poor coating adhesion, requiring rework.
7. Coating Longevity Test
Repeating tape tests (≥10 cycles) confirm no coating transfer, ensuring durability even in harsh conditions.
8. Structural Stress Test
Bottles are pressurized to mimic filling/transport stress-leaks or warping expose structural weaknesses.
9. Upright Stability Check
A specialized gauge ensures the bottle stands perfectly straight-tilt risks instability on shelves or in packaging.
10. Impact Durability Test
Controlled drops simulate real-world handling, ensuring the bottle survives minor knocks without shattering.
11. Seal Integrity Test
Sealed bottles undergo pressure/vacuum tests to detect micro-leaks-even small defects can compromise products in transit or storage.
