4 Cavity Auto Drop PET Blow Machine

A 4 Cavity Auto Drop PET Blow Machine is a high-efficiency PET bottle manufacturing machine designed to produce plastic bottles from PET preforms using the stretch blow-molding process. The machine is equipped with four mould cavities, allowing it to produce four bottles in each cycle, which significantly increases production speed and efficiency compared to lower-cavity machines. It uses infrared heating to heat PET preforms and high-pressure air to shape them into bottles inside precision molds. The auto-drop system automatically releases finished bottles, reducing manual handling and improving productivity. These machines can typically produce 1500–2000 bottles per hour and are widely used for manufacturing bottles ranging from 200 ml to 2 liters for applications such as mineral water, soft drinks, edible oil, pharmaceuticals, cosmetics, and other packaging industries.
