Description
Testron Group provides customers looking for a preform perpendicularity tester in the USA, the UK , and other international markets with various solutions for testing of PET and packaging. Our technical staff can recommend the best configuration for you, taking into account the neck diameter of your preform and other factors.
Detect Preform Alignment Errors Before They Develop Into Expensive Bottle Failures
Any small difference in the dimension of the PET preform will impact the aesthetics, stability, wall thickness, filling process, and the end result of the blow-moulded bottle. The TT-PGP10 Preform Perpendicularity Tester in the USA offers manufacturers of PET preforms, bottle makers, package testing labs, and quality control groups a reliable way to measure preform perpendicularity.

Why Is PET Preform Perpendicularity Important?
The term “perpendicularity” refers to the precision with which the body of the preform is oriented relative to the neck finish or reference axis of the preform. Without a preform perpendicularity tester in the USA, alignment issues go undetected, causing the preform to rotate incorrectly or sit improperly during heating and blow molding.
Issues include:
- Uneven distribution of the material
- Bottle shape problems
- Wall thickness irregularities
- Issues with bottle stability
- Poor appearance
- Misalignment during further processing
- High levels of rework and waste
- Process inconsistencies between batches
An effective PET Preform Perpendicularity Gauge helps manufacturing companies execute reliable PET Bottle and Preform Testing to detect dimensional variation at various stages such as incoming inspection, setup, mold assessment, process development, and quality control.
Rather than detecting the issue after the bottles have been manufactured, it is possible to test the preforms early on.

- Place the preform into the gauge using the neck-finish clamp.
- Set up the measuring contact in the selected point of the preform body.
- Zero the digital indicator as per test procedure.
- Turn the preform through one cycle carefully.
- Note down the difference between the lowest and highest measurements.
- Take note of the deviation measured.
- Compare the reading with the company’s acceptable tolerance.
In order to make a consistent comparison, operators should use the same sample preparation procedure, measurement height, turn procedure, and acceptance criteria for all the batches.
Preform Perpendicularity Tester vs Bottle Perpendicularity Tester
Whereas the two terms could be used interchangeably at times, the test setup may differ depending on the type of sample to be tested.
Test Requirement | Preform Perpendicularity Tester | Bottle Perpendicularity Tester |
Main sample | PET preforms | Final containers |
Test phase | Prior to blow molding | Post bottle manufacturing process |
Primary function | Test for deviations of the preform axisfrom vertical | Test verticality of final container |
Typical user | Preform manufacturer and incoming QA personnel | Bottle makers, fillers and laboratory facilities |
Holding method | Hinged on preform neck finish | Hinged on bottle neck and base geometry |
For users looking for a bottle perpendicularity tester, they need to give dimensions such as height, diameter, bottle neck and base designs, and the measuring range expected.
Procedure for Using the TT-B60 Color Assessment Cabinet
- Arrange the reference standard and test material adjacent to each other in the assessment cabinet.
- Place both the samples next to each other in the same direction.
- Choose the correct light source like D65, TL84, CWF, TL83, F/A, or UV.
- Give ample time to the observer for adaptation to the chosen light source.
- Compare both the samples for variations in shade, hue, brightness, color intensity, fluorescence, and overall color appearance.
- Alternate between different light sources to check the presence of metamerism.
- Note down these results based on your company’s quality control procedure.
- Check the lamp’s operating time and change the lamp, if required.
For greater uniformity, it is recommended that the sample alignment, viewing distance, observer’s position, inspection period, and acceptance criteria remain constant every time.
