Importance of testing perpendicularity of Preforms

Responsive image

Preforms are widely used to create bottles and other containers in the PET industry. It is important to get the right shape and size for preforms because they will determine the final shape and size of the product. If the preform is too large, it will not be able to fit into the mold properly and will result in an uneven or warped product. If the preform is too small, it will not fill the mold completely and will result in a product with thin walls and weak structural integrity. The weak structural integrity of the preforms will ultimately affect its quality. Thus, we at Testronix have designed a high-quality preform perpendicularity tester that is used to test the shape and size of preforms. Here in this blog, we are going to provide you the information about the importance of testing the perpendicularity of preforms. We will also discuss how the Testronix preform perpendicularity tester will help to test the perpendicularity of preforms with ease.

Why it is important to test the shape and size of preforms before delivery?

Preforms are an important part of the manufacturing process, and it is crucial to ensure that they are perpendicular. Testing the perpendicularity of preforms is important to ensure that the materials can perfectly be balanced and is free from quality defect.

To ensure that a preform is a perpendicular, manufacturers test the preforms before they are used in the production process. By doing this, they can avoid any issues that could occur if the preforms are not perpendicular.

Besides this, if the preform is not perpendicular then, it will affect the strength and stability of the product. If the preform is not perpendicular then it can easily break and even collapse.

Thus, to make it easy for PET and preform manufacturer to conduct the perpendicularity test of these materials, we at Testronix has designed a quality perpendicularity tester. This is one of the efficient lab testing equipment that provides reliable testing results for preforms.

This testing instrument is highly useful in the PET bottle industry. Now, let us discuss brief information about Testronix preform perpendicularity tester.

Introduction about Testronix preform perpendicularity tester

In the PET bottle manufacturing industry, it is important for PET bottle manufacturers to conduct quality tests on the materials. One of the crucial factors that needed to be taken care of is its perpendicularity. Testing the verticality or perpendicularity of PET bottles is an important part of the quality control process as a slight difference can lead to the failure of the product and can affect its quality. Testronix preform perpendicularity testers have been designed with high-end features that make it easier for manufacturers to conduct preform perpendicularity tests.

This easy-to-operate lab testing instrument consists of zero tolerance and adjustable measurement operations for repeatability test measurements. This easy-to-operate lab testing instrument is very reliable and stable testing results. This is a widely used lab testing instrument in PET & preform manufacturing industry. You can read more about the comprehensive guide to using the Testronix perpendicularity tester.

Now, let us discuss the working of the preform perpendicularity tester.

Working to preform perpendicularity tester

As the name suggests, a perpendicularity tester is used to test the perpendicularity of preforms. This is important because preforms that are not perpendicular can cause problems during the molding process, including uneven filling, incomplete molding, and poor dimensional accuracy.

Thus, you can easily conduct preform perpendicularity tests with the help of this quality lab testing instrument. To conduct this test, you can follow the steps mentioned below.

  • Place the magnetic stand on the base plate by moving the knob ON/OFF.

  • Adjust the dial gauge and mark the points on preform for 360 degrees that the user needs to test.

  • Put the sample in preform holder in such a manner that the gauge knob touches point 1 and presses up to 2 mm.

  • Set the gauge to zero and rotate the sample manually. If the reading remains zero then it means that the sample will be perfectly perpendicular.

  • A slight difference in the readings will depict that the sample will be will not be perpendicular.

  • Rotate the sample and measure the deviation in the preform perpendicularity from a digital gauge.

In this way, you can easily conduct preform perpendicularity test on the materials and ensure that quality products will be delivered to the customers with ease. You can read more about the working of preform perpendicularity tester.
