– Specialized Applications: Mini bottles (100–250 mL) or large jugs (3–5 L) may require customized molds and adjustments to the blowing process.
Ensure the machine and mold design support your target volume range. Some systems offer quick-change mold kits for flexibility across volumes.
Preform Compatibility
Preforms are the test-tube-shaped precursors to bottles and must match the machine’s specifications:
– Neck Finish: Confirm that the preform neck (e.g., 28mm, 38mm PCO) is compatible with the mold and capping equipment.
– Preform Weight & Dimensions: Match preform weight (e.g., 18g for 500 mL bottle) and geometry to machine parameters.
– Material: Most lines use PET (polyethylene terephthalate) preforms; verify wall thickness and crystallinity for optimal blow performance.
Using preforms from certified suppliers ensures consistency and reduces defect rates.

Compressed air is essential for the blow molding process, particularly for stretching and inflating preforms.
– Air Pressure: Typically 25–40 bar required, depending on bottle design.
– Air Quality: Use oil-free, dry air to prevent contamination.
– Capacity: Size the compressor to deliver continuous airflow at peak production (e.g., 1–3 m³/min per cavity). Consider a nitrogen booster system for high-barrier applications.
Chiller
Cooling is critical for mold temperature control to ensure dimensional stability and cycle time efficiency.
– Cooling Capacity: Typically 1–2 kW per cavity; higher for larger molds or hot climates.
– Temperature Control: Maintain mold temperature between 8°C and 15°C for optimal PET crystallization.
– Water Quality: Use deionized or softened water to prevent scaling in cooling channels.
Ensure auxiliary systems are properly sized, integrated, and maintained to support uninterrupted production.
In conclusion, sourcing a water bottle assembly line from China presents a strategic opportunity to achieve cost efficiency, high production capacity, and access to advanced manufacturing technologies.
