Configuration: Mitsubishi PLC interface & touch screen, BURKERT solenoid valve, Festo pneumatic component, ABB transducer, OMRON sensor, Schneider electric component.

Automatic blow molding machine is designed uniquely with the innovative and reasonable mechanical structure. During the whole producing process, the bottles mouth faces down to avoid being overheated in the process of heating, which extends the application widely used. We adopt the cheap compressed air as driving power, applying the updated PLC technology to control automatically; presetting parameter, built-in self-diagnosis, alarm and LCD display function. Touch-screen is adopted human interface, friendly and visible which is easy to learn.

Preform up structure

The up one is to control the action of preform conveying structure. If there are too many preforms in the tunnel, the moving will be stopped; if not enough, it will get preforms automatically from preform conveying structure.

Heating tunnel

Preform heating structure is made up of three sets of heating tunnel in serials and one blower. Each heating tunnel has been installed with 8 pieces of far ultra red and quartz lighting tube which are distributed on each side of the heating tunnel.

Mould-closing device

It is located in the middle part of the machine and is composed of mould-closing cylinder, moving template and fixed template, etc. Two halves of the mould are fixed on the fixed template and moving template respectively.

PLC control system

PLC control system can watch on the preform temperature and if all the actions are finished according to the setting programs, if not, the system will stop automatically

to avoid fault expanding. Besides, there are fault reason tips on the touch screen

Blow structure

Thanks to adopting bottom-blow structure, the bottle mouth is always facing down to be prevented from the pollution of dust and dirtiness.

Air separation system

The blowing air and working air is separated from each other. . If the customer is able to use the clean blowing air, it will ensure the production of bottles clean at most.
