There are six kinds of PET Blow Molding Machineries:
Single Stage Blow Molding Machine
Two Stage Blow Molding Machine
Integrated Two Stage Blow Molding Machine
PET Blow Molding Machines
Automatic PET blow molding machine
Semi Automatic PET blow molding machine

Single Stage Blow Molding Machine

  All one-stage injection stretch blow molding machines derived from this original Stretch Blow design are referred to as classic one-stage machines, as the concept has long since been extended into other PET developments. The classic one-stage machines design is extremely versatile in that the same basic machine design can be used to make a wide variety of bottles and jars in all shapes and sizes, which was the standard single-stage machine in the early years, had eight cavities for 1.5 liter bottles.

    Two Stage Blow Molding Machine
In the early developments, preforms were made by continuously extruding a PET Blow Molding tube. To make these preforms, a preform manufacturing machine that took a continuously extruded PET tube, heated and closed one end, and then heated the other and formed a thread finish by blow molding. This process had a fasted output rate, at 12000 preforms per hour, than the early injection molding routes of 8 and 16 cavity moulds. Being extruded, the preforms could be multilayered with barrier materials.

  The system was overtaken by injection molded preforms as the cavitations increased to 32 and beyond. The quality of the injection molded (IM) neck, adding for example vent slots, made the IM finish preferable. Moreover, IM technology is available from more than one company, giving customers greater technical and commercial choice. Two-stage technology machine with six blow moulds operating at around 4000 bottles per hour. Subsequent mould and cooling development increased the output to 6000 bottles per hour.

  Two stage PET processing includes: Making preforms by Injection Molding Blowing bottles by Stretch Blow Molding

  Because it is more flexible than one step processing, it is widely accepted in Plastic packaging market.

 Integrated Two Stage Blow Molding Machine
In Integrated Two Stage approach the preforms were made by more conventional injection molding routes (with the number of cavities optimized to match the required output) and then, while still hot, were carried to a separate blowing machine with the optimized number of blow moulds to suit the required output. This was the first integrated approach to PET bottle making. Here the equipment had the same number of injection cavities as blowing molds. This was a more compact approach and proved ideal for small batch output with excellent glossy surfaces.

 PET Blow Molding Machinery
PET Blow Molding Machineries are suitable for small and medium sized bottle makers and drinks manufacturers worldwide to produce their own bottle. The machine starts with the preform, heat it, and then stretch-blow the heated preform in the blow mold into oriented PET container. According to different requirement, PET Blow Molding Machine has the ability to produce PET bottle from narrow neck finishes to wide mouth finishes in the size from 5 ml to 20,000 ml.

 The wide applicability for both narrow and wide neck, reliable capability make PET Blow Molding Machine become popular and attractive to medium and small size bottle and drink manufacturer all over the world. PET bottles and containers are widely utilized in food and drink industry. PET has the advantages of virtually unbreakable, easy to handle and transport, low cost and easy to manufacture and recycle.

There are two type of Pet Blow Molding Machine:

Automatic Pet Blow Molding Machine

Semi-Automatic Pet Blow Molding Machine 

 Automatic PET Blow Molding Machine

Automatic PET Blow Molding Machine is a new generation of fully automatic and versatile machine for mass production of PET bottles and jars. Ideally suitable for large scale factories and for applications where stringent quality requirements have to be met.

Substantial reduction in operating cost is achieved by saving of manpower.

There are two types of Automatic PET Blow Molding Machine

One Stage Automatic PET Blow Molding Machine

Two Stage Automatic PET Blow Molding Machine

 Full-automatic PET stretch blow molding machine is the most stable two-step automatic stretch blow molding machine. It has one to four cavities. It can blow bottles in shapes such as carbonated, mineral, pesticide, cosmetics, wide-mouth, hot filling, and other packing containers, which is made of plastic of crystalline type such as PET and PP etc.
Features (Automatic PET Blow Molding Machine)

 Runs stably, whether voltage is 200V or 240V, or whether room temperature is 0C or 400C.

  Conveying preforms automatically with conveyor.
Strong penetrability and good and swift distribution of the heat by letting the bottles rotate by itself and revolute in the rails simultaneously in the infrared preheater.
Minimum parameter settings through touch LCD, normally only temperature settings should be regulated, no need to play with time settings; Multi-language interfaces

   Easy installation and starting
  Satisfaction with different atmospheric pressure for blowing and mechanical action by dividing the blowing and action into three parts in the air pressure diagram of the machine.
More mechanical & synchronized design to reduce fault to minimum level.

  Low rejection rate
Air recycling unit to save compressed air 20~25%, Reduced heating power, Driving is mostly done by motor directly, instead of compressed air.
200% more efficient than traditional one.

 Adopts Aluminum mold, lighter to be installed or unloaded; 10 molding data memories to make mold changeover quicker.

 High safeties with security automatic-locking apparatus in each mechanical action, which will make the procedures turn into a state of safety in case of a breakdown in certain procedure.

 Safe, reliable, and unique design of the position of valve to make the air pressure diagram of the machine easier to understand.

 Semi Automatic PET Blow Molding Machine

  SEMI-AUTO PET blow molding machines are the most cost-effective solution for mass production of jars and bottles for small and medium scale factories. The machines are also designed for the production of big jars and containers.

There are two types of Semi Automatic PET Blow Molding Machine

One Stage Semi Automatic PET Blow Molding Machine

 Two Stage Semi Automatic PET Blow Molding Machine

 Two Stage Semi Automatic PET Blow Molding Machines are fit to blow carbonated beverage bottles, mineral water bottles, cosmetics bottles and hot-filling bottles. With microcomputer controlling system, it controls various technical parameter needed more accurately and more steadily. It can operate easily without any special training and more safely.
