Quality By Vision Score Residual Gauge

The Score Residual Gauge is an inexpensive, accurate and feature-rich can inspection system for any type of easy open end metal package. 


Brought to you by Quality By Vision, our vision inspection specialist brand, the Score Residual Gauge is a computerized laser score residual gauge 

The difference between a good end and an end that doesn’t open – or a tab that breaks off – is only a few microns. Therefore high accuracy repeatable measurements are essential.  

Our vision inspection system is an inexpensive, accurate and feature-rich gauging solution for any type of easy open end metal package. It offers you precise, non destructive testing and saves you money. 

The problem with a manual can inspection system 

Until we arrived on the scene, alternative microscope-based gauges depended on skilled operators. They had to manually focus on the score groove using an external video monitor and micrometer. However, manually focusing on the score is highly subjective (one person saying this point is in focus, while another says it’s not). 

The high reliance on operators produces a lower GR&R rating, as various operators will evaluate the correct focus differently. A study conducted by our customers indicates that the repeatability of such systems is approximately 5-7 microns (0.0002″-3″)! 

Limitations of other methods 

There are other accepted methods for measuring easy open ends (e.g., pop and tear). But they only indicate high or low pull values. Pop and tear gauges can’t specify where the problem is located and what’s causing it. Whether the problem may be low or high residual value or tooling wear.  

These systems are usually quite expensive, as they require an external monitor, an expensive indicator and decoder. They provide SPC and reporting through an additional computer system and software that increase the costs even more.  

The Quality by Vision Score Residual Gauge 

Our Score Residual Gauge is extremely cost effective and produces a repeatability of +/- 1 micron (0.00005″). The system is easier to maintain since there are no additional peripherals (decoders or video monitors). The can inspection system is directly connected to the computer via a single USB cable. 

Our expertise in optics, software and laser technologies provides a reliable accurate measurement, improving the accuracy and repeatability regardless of the user. There is absolutely no subjectivity risk – different operators will get the same result. 

Multi-testing can inspection system 

The Score Residual Gauge is a robust, accurate and non-destructive testing system for easy open end measurements. 

In addition to the high accuracy score residual measurement, our Score Residual Gauge performs additional important measurements at no extra!  

Our laser score system will scan a score groove profile, effectively replacing the need to epoxy the end and do a metallurgic cross section! It can even offer the option to measure rivet thickness and rivet diameter. 

Crack open our can inspection equipment portfolio 

Across the IP portfolio we make a wide range of vision based can inspection equipment for all types of cans and QA demands.  

For example, the QBV Pop and Tear Tester is a high accuracy, programmable and automatic can inspection system. It measures the force needed to pop and tear an easy open food or beverage end or peel off end. 

Alternatively, check out the 360° Can Inspection module, a highly accurate, reliable and proven mix-up and integrity detection system for lithographed and labeled cans. 

If you work with aluminum or steel cans, the SEAMscan XTS III will increase the accuracy of your double seam inspection testing and reduce spoilage – saving you time and money.  

Can inspection equipment expertise

Over many decades of creating vision based can inspection equipment we’ve learnt a lot about optimal processes to follow and building the most reliable, accurate devices. We like to share the insight we’ve gained across the knowledgebase section of our website.  

We’ve published lots of blogs relating to can inspection equipment. Like this piece – 2-piece Vs 3-piece cans: choosing the right packaging. Or this one which explores some commonly asked questions relating to can seam inspection.  

If you appreciate this type of can inspection equipment content then take some time to explore our website. You’ll find lots more blogs, videos and advice from our experts.

The Problem

With rising pressures on canneries and can makers to increase productivity, minimize both changeover time and unplanned stops – while ensuring higher quality closures – accurate seamer setup is vital.  

The Solution

Our customer needed a reliable instrument to speed up their seamer changeovers. We presented the ‘perfect’ solution in the Quality By Vision Clearance Gauge. It takes the guesswork out of seamer setup, improves seam integrity, increases uptime and rapidly makes changeovers. 

The Result

A spokesperson for industry-leading metal packaging  manufacturer Caniel said: “The team at Industrial Physics identified the perfect solution for our testing requirements and this has been a huge benefit for us.”
