Whole Blow molding Machine running process

Air compressor offer high pressure air both for machine blowing and opretion. For air pressure stable, so that need an air tank for storage air. Because of the air is use for blow plastic bottle, if dirty will pollution inside of the plastic bottle. So need air filler and air dryer, then add another air filter after air dryer. If weather is hot and factory hot, and long time use mold is super hot. So that need fit an mold-cooling to cool the mold. Use air type mold cool will not pollution factory floor with an lot water. Just an little expensive than water mold cooling.

How do the blow molding machine work?

It is made use of air pressure to blowing heating well preform into idea plastic bottle, And because preform in the idea mold, so that final plastic bottle shape decide by the mold.

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.

What is materials of blow molding machine ?

Plastic preform

Preform is materials of plastic bottle, It is produce by injection molding machine. Because injection molding machine is expensive and produce technolgy is difficult. So that most bottle water company is buy preform from prefessional injection molding machine.

The preform are strong and small. one box can package 500psc, and 40hq container can filler half an million piece.

The plastic bottle is not good for freight, because plastic bottle is light and take room, so that freight cost expensive, what’s more, the freight will easy damage a lot plastic bottle.

Why choice neptune blow molding machine?

2000BPH Micro-computer Semi-Automatic Hallow Four cavities Blowing Machine is the new equipment which produces plastic hallow containers of PET.

It has the advantages of energy-saving, small size, low investment, (fast money back), efficient, and reasonable structure and is widely used in food, medicine, cosmetic, pesticide-killer, chemical and beverage packaging industries.

1. Microcomputer control, easy to operate.
2. Heating part is IR heating tube, controlled by imported controlling silicon. The moving part is equipped with three phases motor, and drived by frequency changing part.
3. There are left and right cylinders in sealing stretching part. the stretching length can be adjusted automatically, and the time for air blowing can be adjusted freely. the bottle blowing can benefit from doing so.
4. The waste air can be exhausted from a silencer inside the machine. It reduces the possibility of creating water drop, and is prevented from making noise.
5. There are two air storage barrels inside the main machine and one high, one low, pressure-reducing valve.
