There are four kinds of PET Blow Molding Machineries:
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 Moulding 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 faster 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.
Integrated Two Stage Blow Molding Machine
In Integrated Two Stage approach the preforms were made by more conventional plastic blowing mold 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.
