SUPET Blow System
Mouth-up & Fully Electrical Servo Driven
Overview
SUPET series linear blow molder for the production of PET bottle are highly versatile system. Mouth-up, down blowing, mechanical CAM driven clamping unit, fully electrical control are this machine’s main features and it can carry out 1500bph/cavity production speed. It is a linear machine, using the bi-orientation blow molding principle, ranging from 4 to 8 cavities, displaying various characteristics and performances while maintaining consistent quality: an efficient answer to numerous production needs.

Technical Description
1、Preform Feeding
The preforms are unloaded in bulk into the preform hopper and are then transported by an elevator belt, the speed of which is controlled by the electronics of the machine. By unscrambling, the preforms are lowered by gravity, neck up, are fed with in-feed star-wheel for loading onto chain spindles continuously.
2、Preform Heating
During the heating phase, the preforms are constantly rotated for a perfectly symmetrical distribution of heat. The ovens are ventilated, and the necks of the preforms are protected from oven-heating by means of protection ramp, cooled with cold water.
3、Pitch Changeover
Upon leaving the heating condition, the preform will be transferring into pitch changeover position by a servo motor. By slider & jaw, the abutting preform’s center distance will change from 50.8mm during heating to mold’s cavity center distance for blowing.
4、Stretching & Blowing
After pitch changeover, the preforms are introduced into the blowing mold by servo motor. The longitudinal stretching of the preform is carried out by a servo motor too, thereby considerably increasing the flexibility of the blow process. Pre-blowing at medium pressure can be adjusted by means of manual valves that make it possible to synchronize it with the stretching. The high-pressure blowing is activated after the pre-blowing, with adjustable time setting.
5、Bottle Discharging
The blown bottles are removed from the molds and feed from the slider & jaw by means of a simple mechanical system. The bottles can be evacuated on air conveyor that directly feed to the filling lines.
