semi automatic 5 gallon PET

YW-B20L semi automatic 5 gallon PET stretch blow molding machine is especially designed to produce 5-gallon bottle. Its output is up to 120BPH for 5-gallon bottle in certain case.

YW-B20L consists of main machine and rotary infrared heater. The ordinary quartz lamp cannot heat preform ideally because the preform wall is excessively thick. The infrared heater with high penetrative force can heat the outside of preform evenly.What is more,inner heater is included for more transparent bottle.

What an operator should do during production is just to put externally heated preform to inner heater and then transfer to the blow mold and press the switch, and then computer will take care of the whole procedure. 

Complete System should include:

  • 1/Main Machine
  • 2/Oven
  • 3/Inner Heater
  • 4/Air Compressor
  • 5/Air Dryer Group
  • 6/Air Tank
  • 7/Air Chiller
  • 8/Blow Mould
