How Torque Tester Test Seal Integrity of Regular Screwed Bottles?

Torque Tester Test Seal Integrity

When it comes to screwing on a continuous thread (CT) cap of any variety, the application then removal torque should be properly measured to ensure proper engagement of a threaded closure to a bottle or jar. It is a common misconception that the tighter you apply a closure to the bottle or jar, the less likely it will leak, but in reality, it is quite the opposite. Excessive torque can cause the cap to tear away from the body, thread stripping, "jumping," or even shattering the closure.

Thus, it is important for you to measure the torque of the bottle in order to assure quality bottles are delivered. Presto is the leading torque tester supplier and provides you with a high-quality torque tester for bottles.

This lab testing instrument from Presto is designed to provide the accurate analysis of the force or torque needed to open a closed cap of a PET bottle. The instrument is highly useful in studying the efficiency of bottle caps in the PET industries. Here in this blog, we are going to provide you with information about how this lab testing instrument will be helpful in testing the seal integrity of regular screwed bottles.

Introduction to Presto torque tester

Proper application of screw-on bottle caps, also known as application and removal torque, should always be measured to ensure the proper function of these screw caps, their liners, and the bottle or jar. Thus, we at Presto have come up with one of the highly advanced testing instruments known as the Digital motorized torque tester model that will help you to measure the quality of the torque of the caps of the bottles.

This Bottle cap torque tester is one of the reliable testing instruments that can be used in different industries like plastic industries, packaging industries, pharmaceutical industries, and industries where PET bottles are used on a large scale. Our digital is equipped with an auto stop and restoration of function that automatically stops the machine from functioning when it reaches a 90-degree angle and returns it to its initial position.

This Torque Testing Machine is duly powder-coated and has been incorporated with the calibration mechanism that ensures the reliability and accuracy of the test results. This testing device has fasteners to clamp the samples so that the test operation may be completed quickly. The lab testing equipment is also fitted with a digital panel that shows the test results in digital format. 

It is the best testing machine that is used to test the quality of the rotating components.

Below, we have listed the features and technical specifications of the Presto torque tester digital motorized model.

Role of torque tester in determining the torque of PET bottles

PET containers are thought to be the greatest packaging material for storing fluids and transporting things safely from one location to the others. Nowadays, manufacturers in every business rejoice at the possibility of packing their food in PET containers since they are completely safe and prevent any form of spillage or item leakage.

Thus, it is important for PET bottle manufacturers to ensure that the caps they are producing are of the highest quality. Any type of malformation observed in PET jugs has a direct impact on the safety, cleanliness, and nature of the items contained inside.

A very precise torque sensor has been embedded in this torque tester for PET bottles, which accurately record the torque applied to the test specimen. The equipment is operated manually, and the torque is determined using a digital display readout. The machine comes with a safety lock pin that stops the clamping device from spinning, preventing excessive torque from being delivered to the torque sensor.
