Insulated Cup Body Mold Technology and Practical Experience (Part 4)
A cup holds stories, and life carries warmth. Hello everyone, "Dong Dong's Cup Talk" is back! In previous articles, http://www.zhanyict.com/en/ProductsDetail-VB-10488.htmlwe've shared insights from both our plastic mold specialist Mr. Feng and metal stamping expert Mr. Ding. Today, we continue with the final installment of our series on insulated cup body mold technologies and practical wisdom.
IV. Quick Guide to Mold Difficulty & Cost Assessment
(Engineer's Rule of Thumb: Difficulty = Number of Processes × Precision Requirements²)
Product type: single-layer cup body
Key features: http://www.zhanyict.com/en/ProductsDetail-VB-10488.html2-time stretching + straight tube type
Difficulty star: ★★
Cost range (10,000 yuan): 2-4
Product type: double-layer cup body
Key features: http://www.zhanyict.com/en/ProductsDetail-VB-10488.html6-time stretching + vacuum brazing
Difficulty star: ★★★★★
Cost range (10,000 yuan): 6-7
Product type: threaded cup cover
Key features: http://www.zhanyict.com/en/ProductsDetail-VB-10488.htmlprecision rolling + sealing surface polishing
Difficulty star: ★★★☆
Cost range (10,000 yuan): 1-2
Cost Drivers:
- Process Count: Each additional drawing stage adds ¥5k-20k
- Tolerance: http://www.zhanyict.com/en/ProductsDetail-VB-10488.htmlImproving mouth precision from ±0.1mm to ±0.05mm doubles machining costs
- Surface Finish: Mirror polish (Ra≤0.1μm) triples costs vs standard polish
V. 20 Years of Hard-Won Lessons
1. Don't Worship Equipment: A German company's €2M press only achieved 70% yield due to poor mold design - proving design accounts for 70% of success.
2. Value of Failure: http://www.zhanyict.com/en/ProductsDetail-VB-10488.htmlOur 2015 ¥1.8M loss on brazing deformation birthed a patented positioning fixture (now saves ¥6M annually).
3. An Engineer's Obsession: Stainless steel molds live by micron-level precision - compromising 0.01mm can destroy a brand's reputation!
(Series Conclusion: Great molds demand equal parts science, craftsmanship, and battle scars.)
