Product Features

1.Put pre-forms into hopper of auto sending device,send to heating stove through belt and drum unit.

2.Bottle pre-forms are sent to pre-form base by guide turn table, the bases get pre-forms and then send to stove for heating one by one.

3.The heating stove has 8-floors infrared lamp to heat pre-forms, the pre-forms run itself and also the infrared lamp can be adjusted temperature independently.

4.Heating stove has pre-form screw head cooling way and stove ventilation and cool air duct, it ensures that pre-forms will not be hard warmed.

5.Discharge warmed pre-forms to outlet guide by discharge pre-form cover, put pre-forms into blowing moulds by manipulator, seal the bottle mouth and extrude the body, also inlet two grade air pressure(pre-blowing pressure and high pressure air) and make pre-form to be bottles. According to the requirement of art, there will inlet cooling water for moulds, all above processes are controlled by main machine computer.

6.After blowing, the manipulator get bottles out of mould and the qualified bottle will be send to guide, this guide can be connected directly to filling line and also can connect to conveying chain, send to bottle warehouse.
