The Secret Science Behind Making 20 Liter Water Bottles Explained Simply

This is our YD-5L-2 Full Automatic PET Blow Molding Machine, designed for producing large-capacity PET bottles up to 5000ml. Compared with standard small beverage bottles, large PET bottles require higher stability during heating, stretching, and blowing. The material distribution must be well controlled to ensure bottle transparency, strength, and consistent forming quality. This model is equipped with a 2-cavity mold system and can reach a theoretical output of around 1500 bottles per hour based on 5000ml bottles. Key specifications: • Max. bottle volume: 5000ml • Number of cavities: 2 • Theoretical output: 1500BPH for 5000ml bottles • Neck diameter range: 38–48mm • Max. bottle diameter: 200mm • Max. bottle height: 390mm • Heating zones: 4 sections • Total power: 45KW • Net weight: approx. 3.0T From preform heating to stretching, blowing, and bottle discharge, every step matters in large PET bottle production.
