CMC-KUHNKE Manual Seam Thickness Gauge

The STG-4000 Manual Seam Thickness Gauge provides objective, repeatable and reliable measurements for beverage, food or aerosol cans. 


Developed by CMC-KUHNKE, our metal testing expert brand, the STG-4000 manual thickness gauge gives you completely operator independent measurement of cans for increased accuracy and consistency.   

It is the first seam thickness gauge designed to closely duplicate hand micrometer readings up to a 603 diameter can (153mm). Our manual thickness gauge does a thorough job – it measures the seam thickness on two or three points at the can seam. 

This innovative seam measuring gauge encounters less false operation than a seam micrometer and the measuring pressure and angle do not change.  

A time-saving seam measuring gauge

The STG-4000 features a number of automatic data transfer options. Our seam thickness gauge will save you time in your process, ultimately saving you money.  

Test approved seam measuring gauge credentials  

The STG-4000 seam thickness gauge is a tried and tested machine that has enjoyed the best R&R and DR results in the industry.  

The Industrial Physics portfolio

Across the IP portfolio we make a wide range of seam thickness gauges and manual thickness gauges to test any aspect of any metal package.  

For example, The SEAMscan SPC System is an affordable, high-resolution tool for double seam inspection and measurement with SPC Reporting. 

If you want to measure the profile and countersink depth of a wide range of food, beverage and aerosol cans, then our CDG-3000 is the ideal manual gauge. 

The AUTO-XTS is a fully-automated, on-line or stand-alone measurement system that provides non-destructive, complete double seam inspection for beverage fillers and metal cans. 

Industrial Physics insight

Over the decades we’ve learnt a thing or two about how to build innovative yet reliable metal packaging testing devices. We like to share this knowledge with our customers and the wider industry. 

You may appreciate this first piece on how to measure the  double seam of a can. Alternatively, our expert team over at the knowledgebase section of our website wrote this piece on 2-piece Vs 3-piece cans: choosing the right packaging.

Success Stories

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.”
