A PET bottle that bulges in the warehouse, leaks at the cap or collapses on a pallet costs more than any lab instrument. As PET bottles testing instruments manufacturers in India, we build the tests that find these faults early, and our suppliers in India network ships to blow moulders, beverage plants and packaging labs.
Pressure and shape behaviour come first. The carbonated bottle burst tester and the multi-station creep and volume expansion tester check whether a bottle survives gas pressure. The top load tester and the drop tester check mechanical abuse in stacking and handling.
Closure and leak integrity are covered by the digital cap torque tester and the vacuum leak tester. Material distribution and appearance are examined with the wall thickness tester, the haze and light transmission meter and the dimension and volume station. The shrinkage oven covers hot-fill and thermal stability. Together they let a plant run first-article approval and routine hourly checks.

Non-contact thickness gauge with a magnetic ball probe that scans blown PET bottles for sidewall, shoulder and base thickness. Used by bottle blowers to optimise material distribution and cut resin weight without losing strength.
Hydraulic pressure tester that fills PET bottles with water and raises pressure until burst or yield, recording the peak pressure. Used by carbonated soft drink bottlers to verify bottle pressure resistance and base design.
Multi-station bottle creep tester that holds filled PET bottles at constant internal pressure and temperature while tracking volume growth and height change. Used by CSD bottle producers to assess long-term shelf stability.
Measurement station with height gauge, vernier fixtures and fill-volume cylinder for checking PET bottle height, diameter, neck finish and brimful capacity. Used in beverage bottle QC to hold dimensions within customer drawings.
Torque meter that measures application and removal torque of screw caps on PET bottles with a rotating chuck. Used by bottlers and cap suppliers to qualify seals and prevent leaks or tamper band failures.
Compression tester that crushes PET bottles vertically between flat platens to record top load strength and deformation. Used by beverage and water bottle makers to confirm stacking and cap-torque performance during storage.
Drop test machine with release mechanism that drops filled and capped PET bottles from set heights onto a rigid floor. Used by packaged water, juice and edible oil bottlers to check leak and fracture resistance during handling.
Hazemeter that measures percent haze and luminous transmittance through the sidewall of clear PET bottles. Used by bottlers to verify clarity of water and juice bottles and to detect over-crystallised or contaminated resin.
Forced-air oven that heats PET bottles at set temperature for a fixed time to measure dimensional shrinkage and distortion. Used by hot fill and aseptic bottle producers to verify heat set performance.
Vacuum chamber leak tester that checks sealed PET bottles under reduced pressure inside water to detect leakage at the neck and cap. Used by packaged beverage and pharma liquid producers to qualify closure integrity.

Preform instruments check the injection-moulded starting piece and PET resin: moisture, viscosity, acetaldehyde, stress and neck dimensions. PET bottle instruments test the blown container as it will be filled, capped, stacked and shipped, using burst, creep, top load, drop, torque and leak tests. A fully integrated bottler needs both groups, while a pure blow moulder with bought-in preforms mainly needs the bottle range.

The complete PET Bottles Testing Instruments range (10 products), in alphabetical order:
Check the maximum pressure against the highest carbonation level you bottle, usually up to 15 bar or more for burst. Confirm the pump and ramp control, the safety enclosure, neck fixtures for your finishes and the display of peak pressure. Also verify water handling and drain, since burst testing is wet work.
Burst testing finds the ultimate pressure limit quickly. Creep testing holds the bottle at working pressure for a time and measures volume growth, which shows whether a bottle will bulge on shelf. Carbonated drink plants need both, while still water bottlers focus on top load, drop and leak tests.
A suitable tester measures both application torque and removal torque, with resolution fine enough for 28 mm and 38 mm closures. Check the range, peak hold, holding fixture for the bottle, and whether it can store results. Good fixtures prevent bottle twist from affecting the reading, so ask for neck clamps for your finish.
Beverage and bottled water plants, edible oil and juice packers, PET blow moulders, dairy and pharma bottle users, brand-owner quality teams and third-party packaging labs purchase this range. A blow moulder typically starts with top load, wall thickness and dimension tools, then adds burst, creep and leak equipment when supplying carbonated drink customers.
Yes. We make and supply these instruments in India and for export. Give us your bottle sizes, pressure levels and voltage, and we will prepare a matching quotation.
It is the vertical force a bottle withstands before buckling, normally measured with the bottle capped and sometimes filled. Plants use it to check that pallets can be stacked and that bottle weight is not reduced too far.
Haze shows how clear a bottle is. High haze comes from crystallisation in the neck or sidewall, poor preform heating or contamination. Brand owners set limits because clear bottles are a key part of product appearance.
Hot-fill and returnable bottles need thermal and creep tests at higher temperature. Tell us your fill temperature, and we will advise on the oven and creep tester specification.
Load cells, pressure transducers and torque sensors are checked before dispatch, and calibration certificates can be quoted for accredited labs. Mention this requirement in the enquiry, with the parameters you need certified.
