BLOW MOULDING PROCESS:
MACHINE ADVANTAGES
1.Energy saving over 50%, benefit from minimized preform heating pitch.
2. Structures with optimized design enable a higher per cavity output of 1,800-2,000bph.
3. Comparing with standard ordinary machine, few air cylinders in use, less maintenance cost.
4. Equipped with servo motors, faster action and no separate low pressure air input is required for operation.
KEY FEATURES
1. Preform Feeding
1）Rotary dial plate design enablecontinuousand high speed preformfeeding；
2）No pneumatic claws, more reliable and less maintenance；
3）Multiple protection device for precise preform feeding.
2. Transfer and heating
1）Horizontal rotation transfer style, no preform turnover, simple structure；
2）Minimized preform heating pitch for less energy consumption；
3）Cooling channel applied in neck area to guarantee no deform of preform neck；
4）Optimized ventilation to ensure heating consistency；
5）Equipped with function of preform temperature detection.
3. Transfer and bottle out
1）Servo motor driving for preform transfer and location with quick and precise action；
2）No pneumatic clampers were used for bottle taking out, less maintenance in future, less running cost.
4. Clamping and stretching blow molding
1）Servo motor clamping system with synchronized base blow mold for fast response operation；
2）Precision electromagnetic blowing valve group for fast and high productivity；
3）No link rod,no toggle structure, simple and reliable clamping system. Less maintenance required.
5. Controlling
Siemens controlling system with 9 inch touch screen for simple and stable operation.
6. Others
1）Simplified construction, quick mold changedesign；
2）Low power and air consumption, longer life-span and lower wear, more clean structure.
3）Be able to be connected directly to air conveyor to bottling production line easily.
