Filling and capping production lines—for complete liquid packaging lines, look to Dailong or Xinmeixing; for aseptic dairy lines, look to Zhongya (Source: Industry comparative review): Dailong: Pepsi’s sole supplier in Asia / 1,000+ production lines (Source: Dailong); Xinmeixing: Established in 1986 / 48,000 bottles per hour (Source: Xinmeixing)—Selection Criteria: Production capacity + product format + complete line capabilities (integrated blow-fill-cap systems save space; Source: King Machine).
I.
Dailong
History: Launched the first domestically produced PET blow molding machine in 1998 (breaking the monopoly held by European and American companies; Source: Dailong); Status: Pepsi’s sole supplier in Asia / A “hidden champion” in global liquid packaging (Source: Industry); Scale: Over 1,000 intelligent production lines installed / Exports to 50+ countries (Source: Industry); Products: Blow-fill-cap / Blow-label-fill-cap / Filling lines (Source: Dailong); Aseptic Capabilities: 54,000 bottles per hour dry-type aseptic line (Source: Dailong)—Dailong: High-speed complete lines (water/beverages/condiments).
II. Newamstar
History: Established in 1986 / Listed company (Source: Newamstar); Scale: Serves over 3,000 production lines globally (Source: Newamstar); Pioneering Achievement: China’s first 36,000-bottle-per-hour blow-fill-cap block (2010, Source: Newamstar); Upgrade: 48,000 bottles per hour (2015, Source: Newamstar); Case Study: 4 lines for Dongpeng Special Drink (12 million bottles/day, Source: Industry) — Newamstar: The “All-Rounder” in blow-fill-cap technology (modular integration saves space, Source: King Machine).
III.
Other Manufacturers
Zhongya Machinery: Aseptic dairy filling (Source: Comparative Review); Shanghai Zongyi: Full-process coverage + flexible non-standard solutions (Source: Comparative Review); Pulisheng: Liquid packaging; Lehui International: Complete beer production lines; Small-scale lines: Alibaba/Made-in-China.com ($600–$12,800, Source: Accio) — Selection based on segment (dairy/beer/personal care products).
IV.
Selection Criteria
Capacity: 12,000–54,000 bottles per hour (Source: King Machine); Product: Water/beverages/dairy/condiments; Process: Cold fill/hot fill/aseptic; Container: PET/glass/cans; Integration: Blow-fill-cap block (saves factory floor space + reduces investment, Source: King Machine) — Selection factors: Capacity + process + container type (aseptic requires the strictest standards).
V. Assessment of Whole-Line Capabilities
1. Pre-treatment (water treatment/mixing); 2. Bottle blowing (in-house developed); 3. Filling & capping (main unit precision); 4. Downstream processing (labeling, packing, palletizing); 5. Software (smart factory/MES)—Assessment: In-house development rate of the whole line (high risk associated with assembling outsourced components).
VI.
Acceptance Criteria
Production capacity: Actual bottles per hour (full-load test); Precision: Filling error (±1%); Capping: Torque consistency/leakage; Aseptic performance: Culture medium validation (Source: Tech-Long); Stability: Continuous operation—Acceptance: Capacity + Precision + Aseptic performance (to be stipulated in the contract).
VII.
Procurement Recommendations
1. High-speed water lines: Choose Tech-Long or Newamstar; 2. Aseptic dairy lines: Choose Zhongya; 3. Small-scale customized lines: Choose Zongyi; 4. Calculate capacity first (identify bottleneck stations); 5. Turnkey solutions (from water treatment to palletizing)—Filling & capping lines: Tech-Long and Newamstar are industry leaders;
Zhongya specializes in aseptic systems (prioritize capacity/precision acceptance and in-house whole-line development).
