What is a Preform ?

Preform is to form or shape a product to a preliminary shape and size. In simple terms, PET (Polyethylene Terephthalate) material is formed to a shape which is moulded to a specific shape and then blown to its final shape in the blowing machine as per the mould design.

What makes SMARTPET Preforms unique?

There is one unique characteristic of SMARTPET preform, which is that the final product that will be made from it will be clear and transparent and the surface will be smooth and sparkling, which will attract the consumer’s attention. This makes the SMARTPET preform a unique product. On the other hand, although the SMARTPET preform can create a similar look and feel just like glass, it is not fragile as glass. The wall is strong and tough, which makes the container unbreakable. Finally, SMARTPET preforms are 100% recyclable which makes them not ending up at landfills.

Which Features make SMARTPET Preforms with Best quality.

  • Uniform Wall Thickness.
  • Excellent surface finish with perfect shine.
  • No Flash marks on the edges for smoother finish.
  • Accurate Thread Finish, for better Closure/Cap Fitting.
  • No Split Lines on Preforms for better finish of bottles

PET Preform Injection Moulding Process

Injection molding process is one of the popular processes for manufacturing bulk quantities of preforms. It consists of three major steps:

1. Drying: Hopper drying is the most commonly used method of removing humidity from PET. Hopper dryers have autoloaders where PET is conveyed continuously for an even drying. Dehumidifier method uses a closed loop system and brings excellent surface finish and physical properties. It uses a closed loop system to achieve drying of PET in an unvarying way.

2. Melting: When the screw is pushed forward, injection cavity gets filled up completely with molten plastic. There is a temperature difference of around 8 to 10 degree celsius at the front and rear end of injection molding machine. They are typically 270 to 275 degrees and 280 to 285 degrees respectively. Temperature may vary based on the design of the mold and other technical specifications. Molten PET gets entered through the cavities and cooled slowly to solidify it.

3. Cooling and molding: Temperature is maintained in such a way that PET gets solidify in a consistent manner. Cooling water is used to bring down the temperature of the mold. Since the temperature is quite low (around 15 to 20 degree Celsius), internal pressure has to be maintained properly to avoid breakage or deformities. A water chiller is used for cooling preforms under controlled pressure of 5Bar. An automated gripper takes out cooled preforms and deposit to conveyer belts. Preforms get ejected from the mold and send to either packaging or re-heating if they have to be sent for blowing process immediately.

Why Choose our preforms?

We take care of all the aspects initially while manufacturing the SMARTPET Preforms in a world class facility that are a big problem in blowing stage later on. All the PET Preforms are crafted to perfection and no compromise has been done on the quality of the SMARTPET Preform.
