    Introducing the P1 preform transmission instrument

Our first customer had problems with the red preforms they made for Heinz ketchup bottles. Visual checks didn’t work, they wasted material getting it right and when Heinz made bottles out of the preforms, the color variation was so big they shipped everything back. To help them, we made a high-quality, easy-to-use instrument that tells them if the color of the preform is correct. Now many years later, over 50+ preform manufacturing companies use our P1 instrument saving money, material, and customers.

Product description

The P1 preform inspection system is an easy to use, accurate and stable industrial instrument that has been designed exclusively for measuring preform transmission values.

Due to its robust housing it can be placed directly next to the Injection Molding System to measure preforms periodically to detect changes quickly.

It has been designed to keep operating errors to a minimum. It has only 2 buttons and the reflection chamber has guides so it will be positioned the same way every time.

The instrument measures the amount of light passing through a preform from fully transparent to almost opaque. It is designed to provide more accuracy the more opaque a preform is. Almost complete opaque preforms can be measured, up to only 0,1% transmission

The P1 is designed for the plastic preform industry.


Small changes in transmission values are detected in an early stage minimizing waste and valuable production time. Alternatively the instrument can be used to detect variations in transmission values due to preform position in the mold

-Guarantee your customers a high and constant colour quality.
-Very easy to use.
-No more human errors during visual inspection.
-Very robust

Optional windows software

The instrument has an ethernet port which can be used to connect the instrument to a network or PC to transmit measured data for logging.
PET Preform Quality data can be logged to a company database for client reporting or to lookup data in case of customer complaints.

There is an optional SDK (software development kit) available with a technical description of the protocol used and example source code of a simple c# windows software allowing your engineers a quick start adding data to your database or giving you the option to create your own software.

We like to help you get the quality tools you need. We can make custom instruments for our customers if needed. The P1 gives a percentage of light of the full (visual) spectrum, if you need full color measurement or even full spectral data of your performs let us know. Or perhaps you are interested in the UV blocking of your preforms.

Contact us with your specifications or questions and we can schedule an appointment to discuss your specific requirements.
