Background
Well-known gauges for measuring wall thickness of parts include micrometer, caliper, thickness gauge, caliper gauge, and the like. These tools are relatively accurate and practical in measuring a plate-like object. However, for some common thin-mouth PET bottle blanks, there is a limit to using these tools because of its large space in the container and small mouth size.
Currently, there is no ready-made measuring tool that can directly measure the wall thickness of PET bottle blanks. The conventional method is to measure the inner diameter and the outer diameter by using a micrometer, and then subtract the two to obtain the wall thickness. However, the measured values of the measurement method are often not accurate enough, the error is large, and the measurement efficiency is low. We therefore propose a new wall thickness measuring device.
