What is semiautomatic blow molding machine?

Two step bottle making process. The bottle blowing machine is the second step.

It is pet plastic bottle making machine. Heating preform and manual moved to blowing into plastic bottle. It is an independent bottle blow molding machine. Can not directly connect with filling machine.

Stretch semiautomatic blow molding machine is use to produce different shape pet plastic bottle. It is widely use to produce mineral water bottle, pure water bottle and carbonated drink bottle. It made use of pet preform to blowing into idea plastic bottle according the bottle mold.

It included two main part:

1. Blowing unit


The machine adopts revolving infrared pre-heater. It ensures extremely even heating for PET preforms.
The machine uses mechanical-double-arm mould clamping which ensure the mould be closed tightly even in high pressure.

2. Heater unit


Rotary infrared heater heats pre-forms by moving pre-forms to pass through infrared heating area twice. by this method, heating is uniform and of high efficiency,
Infrared heating area is strictly divided into seven zones of A,B,C,D,E,F,G from up to down, Temperature requirements for all parts of pre-form are satisfied by controlling temperature of corresponding zones.
The feeding of pre-form for heating and taking away of heated pre-form shall be conducted manually which is simple and convenient.

How do the blow molding machine work?

Worker need manual insert preform on heating oven. And got the heating well preform to the blowing machine. Then press the button and blow the air into the preform. So that the preform will blowing into idea plastic bottle according the bottle mold.

Main machine: composed of machine body, closing structure, sealing stretching, and blowing machine, all together four parts.
1. Closing structure is composed of fixed mould plate, moving mould plate, cylinder, and double bending arms and connecting poles. The air source is controlled by the helping of the connecting poles and double bending arms; the plates open and close thereby.
2. The sealing stretching is controlled respectively by two left/right cylinders independently, conducting left and right stretching and sealing. It is also controlled by two solenoid valves of two position and five routes. They can adjust the air blowing retention time of the two cylinders respectively.
3. The air source comes from the second level filter first, and then goes to two big size two-position-three-routes solenoid valves to blow high-pressure air to make bottles from perform .
4.The operation screen is installed with microcomputer controller. It has LCD displaying function, manual or automatic functions switches. They control the time of opening and closing of mould, sealing stretching and blowing. Easy and convenient to operate.
