Blow Molding Machine

1. Applications of Blow Molding Machines

• Beverages – water, juice, tea, carbonated drinks, beer, liquor, energy drinks.
• Food Products – edible oil, sauces, vinegar, condiments, dairy products.
• Daily Care Products – shampoo, cosmetics, detergent, disinfectant.
• Pharmaceuticals – medicine bottles, syrups, health supplements.

2. How Does a Blow Molding Machine Work?

• Preform Loading – plastic preforms are fed into the heating oven.
• Preform Heating – infrared lamps heat the preforms evenly.
