Equipment Features
- Servo-driven high efficiency Servo motor control on stretching and clamping delivers fast, accurate and energy-saving operation, with output up to several thousand bottles per hour depending on cavity number.
- Precise infrared preform heating Multi-zone infrared heating oven with independent temperature control ensures uniform preform heating and consistent wall thickness distribution of finished bottles.
- Stable bottle quality High clamping force and precise mould alignment guarantee stable bottle shape, good transparency and reliable pressure resistance for carbonated applications.
- Wide bottle compatibility Handles a wide range of bottle volumes and neck sizes through quick mould change, suitable for water, CSD, juice and edible oil bottles.
- Safe & intelligent control PLC + touch screen control with full safety interlocks, fault self-diagnosis and easy parameter setting for stable continuous production.
Working Principle
PET preforms are fed and aligned automatically, then conveyed through an infrared heating oven where they are heated to the ideal forming temperature. The heated preforms enter the blowing station, where a stretch rod extends them axially while high-pressure air expands them radially against the mould cavity. After cooling and pressure release, the moulds open and the finished bottles are discharged automatically.
Application Fields
- Drinking water: Production of PET bottles for purified, mineral and spring water
- Carbonated & juice: Pressure-resistant bottles for CSD, and bottles for juice and tea beverages
- Other liquids: PET bottles for edible oil, condiments and daily-chemical products
