Glass bottle plastic bottle test bottle bottom bottle thickness solution

December 01, 2022

Abstract : With the continuous maturity of modern packaging technology, for bottle manufacturers, whether it is a Plastic Bottle or a glass bottle, it is necessary to strictly test its "physical performance is up to standard", and the thickness of the bottom of the bottle and the wall of the bottle It is an indispensable test item. Once the thickness of the bottom of the bottle or the wall of the bottle is not up to standard, it will directly affect the performance of the bottle after it is put on the market, causing trouble for the merchants and users.

This article takes Jinan Saicheng's self-developed " WBT-G wall thickness thickness gauge " as an example, from the perspective of the necessity of thickness measurement of bottle products, the application range of equipment, the technical parameters of equipment, etc. I hope to provide valuable reference to enterprises and institutions in need.

Body :

Manufacturers engaged in the production of bottle packaging know that the early measurement of bottle thickness is more focused on the bottom of the bottle. However, with the emergence of feedback after the product is put on the market, the measurement of the thickness of the bottle has become an important indicator for monitoring by relevant national departments. Therefore, regardless of the bottle of the material, the thickness detection of the bottom of the bottle and the wall of the bottle is an indispensable test link before leaving the factory.

In general, the thinner part of the bottle is often the weak part of the bottle's mechanical properties, barrier properties and other indicators, it will directly lead to the reduction of all performance of the entire bottle, so that the product can not complete the expected use of the factory. The effect can be described as a loss of a thousand miles. Especially in today's increasingly fierce competition for packaging materials, "lightweight" has gradually become a major trend in the development of glass bottles.

The so-called "lightweight" is to reduce the weight ratio of glass bottles, in order to improve their greenness and economy in society. Depending on the application, the weight ratio of the lightweight bottle is generally between 0.15 and 0.8. The weight ratio of the bottle is small, the wall of the bottle is relatively thin, the weight is lighter, and the wall thickness is only 2 to 2.5 mm on average. Then, how to ensure that the various indicators of the bottle meet the standard and win the competition in the market for the demand for lightweight glass bottles, it is very necessary to accurately detect the thickness of the bottom of the bottle and the wall of the bottle.

Defects of traditional wall thickness detection methods

Conventional wall thickness measurement methods include contact measurement, magnetic induction thickness test, and slice test thickness. However, due to the limitations of technology and materials at the time, most of these traditional methods have corresponding defects, which affect the final measurement results. For example, the magnetic induction thickness test is difficult to measure for the concave and convex parts of the bottle body; the contact measurement requires a lot of manpower; the slice type needs to cut the bottle.

The WBT-G wall thickness thickness gauge developed by Jinan Saicheng makes the inspection perfect.

Compared with the traditional detection method, Jinan Saicheng's self-developed "WBT-G wall thickness thickness gauge" adopts the world's advanced " capacitance sensing " technology, which is convenient for users to use quickly and accurately. Still belongs to ling first position. Therefore, once listed, it will immediately receive the support and trust of all manufacturers.

At present, this instrument has three absolute advantages in China:

At the same time, it has the standard of the double side of the bottle bottom and the bottle wall, and the resolution can reach 0.001mm.
The instrument has a long range of up to 12.7mm, which can meet the requirements of bottles of different heights and can be customized.
The auxiliary measuring disc can be rotated 360° and has its own scale mark to ensure accurate measurement return.

In addition, in order to facilitate everyone to understand the instrument, Jinan Saicheng will also announce its technical parameters as follows:

Technical Parameters:

Instrument range: 0-12.7mm

Graduation value: 0.001mm

Sample diameter: 5-30mm
