working process

whole process and equipment of auto blow molding machine
  • 1. Preforms unscrambler will automatic load the preform.
  • 2. Machinery gear will transfers the preform to the heating oven
  • 3. 10psc infrared lamps can be adjusted individually to control the temperature of oven. Preform automatically rotate can make sure preform heating evenly. The infrared thermometer inspecting temperature and will automatic adjust it by itself. All parameter can saw in the touch screen of the Neptune automatic blow molding machine and can easy setting. So that can always fit the best heating temperature
  • 4. The temperature sensor can inspectst the temperature of the preforms. According compare with preset data, it will automatic feedback data to oven, and Oven will automatic adjust the temperature to the necessary temperature.
  • 5. Preforms star-wheel will automatic transfer the after heated preform to the blow mold.
  • 6. First, the preform will stretched in the mold. And then will blow into shape plastic bottle by high pressure air.
  • 7. Machinery gear will transfers the plastic bottle to the air conveyor belt.
  • 8. Air conveyor belt will directly send plastic bottle to washing filling capping machine.

It the second step of the pet bottle making machine. The first is injection plastic preform.

Less than 1% bottled water company will produce preform by themselves. Because the pet preform is closed to oil industry. It is very low gross and occupy bottled water company cash flow. Leave it to professional preform factory will be better.

Why most bottled water company produce plastic bottle themselves?

Why Most Bottled Water Company Produce Plastic Water Bottle Themselves?

  1. The most import is the empty take room. Freight will cost big
  2. Empty bottle will easy crushed if stacked, its inside without anything
  3. The empty plastic bottle will been pollution if long time touch air
  4. The plastic bottle making process need heating the preform into high temperature, So that produce out plastic bottle is sterile. Fast finished bottling and sealling. Reduce touch air
  5. Famous bottled water company usually have an unique bottle design. It can protect their brand
  6. In long time it is save the cost
