Can inspection: how can you do it?

The can is a marvelous invention. A simple but trusty and important design that’s become an integral driver in the success of many different industries. As such, there’s a wide range of can testing equipment available.

Cans are used  by companies working in everything from food and drink through to the paint and automotive sectors. The humble 2  piece can is available in all shapes and sizes. They have helped millions of people to eat fresher produce and millions of companies to transport their products safely all over the world.

But here’s the bad news. When things go wrong, they go very wrong.  And just one leaking can lead to a costly recall headache and some serious reputational risk.

Which is why an accurate and reliable empty and full can inspection process is so important!

Given the humble can’s versatility you can see why there are many different methods of can inspection. A multitude of approaches, whether you are looking to test beer cans or undertake food can inspection. With various options for empty and full can inspections.


A glossary of popular can testing methods

Industrial Physics is an industry-leading manufacturer of metal packaging inspection equipment. In this blog we take a look at some of the more popular can inspection methods used across industry; all of which we can help you with – as well as many more!


Empty can inspection

If you’re a two piece can maker, you’ll need to check your products carefully before you dispatch them. But if you are a can filler only, it’s still wise to undertake empty can inspection techniques before adding your precious products.

A good empty can inspection system will detect defects quickly and accurately on the flange, bottom and the inner sidewalls of the can. If there is pollution and spots on the inside…it will spot them. Empty can inspection will also flag up your flange dents, measure your flange width and check the overall ovality!


Abrasion can testing

Wear and tear will take a toll on your canned goods . In order to keep metal packaging looking its best for longer, can testing will help you to understand how it fares when it rubs, grinds, or scrapes against other materials. This knowledge will guide you in identifying weak areas in your packages, so you can make steps to improve the visual appeal and achieve a longer shelf life.


A can testing abrasion inspection machine will accurately measure the resistance of your materials, offering a clear picture of their aggregate toughness and abrasion resistance. Showing you how your metal materials stand the test-of-time when crushed or left to degrade and disintegrate.


360 degree can inspection

Get a complete 360˚ view of your cans : these days you can invest in highly accurate technology ‘mix-up and integrity detection’ can inspection systems.

You no longer have to use separate machines for barcode reading, decoration inspection or damage checks. There are can inspection devices that offer all of this – in one package. You can even add extra modules for things like seam, flange and interior can testing.


Code reading can testing

Check your product codes are correct, are readable, and are in the right place, with a code reading can inspection machine.

Product specific codes help you with your inventory and supply chain security. They also help with product recall. You face hefty fines or even lawsuits if your products are not coded properly.

Avoid this pain with a code reading can testing device. You can inspect ink-jet, laser or thermotransfer, or alpha-numeric barcodes on your packages. They will help you to monitor production dates, shelf life codes, track and trace code, barcode codes, 2D data matrix codes or QR codes.


Corrosion can testing

Need to understand how well your products will stand the test of time? A cyclic corrosion can inspection test chamber  will deliver the precise environmental test conditions demanded by modern industry.

A humidity and humidity conditioning cabinet enables you to reproduce the test conditions of high humidity at constant or cycling temperatures. You can even find salt spray cabinets that test both components and coated test panels for all manner of coastal environments!


Leak can testing

One leaking can is all it takes to damage a hard earned reputation.  So plug any gaps in your can-making or can-filling process with a leak can testing device.

Make sure the contents of your metal packages don’t leak out and stop ambient materials from the environment sneaking in. There are leak testing can inspection devices to accurately inspect the complete seam around each and every can.


Adhesion can testing

If your coatings don’t stick, then time spent in perfecting the design of your cans has been wasted. A paint adhesion can inspection machine enables you to discover the aesthetic quality of your products instantly.

These machines will let you see if the paint and treatments you select will effectively stick to your substrates. They’ll determine the failure point of your adhesive – the least amount of duress that causes your product to fail a quality control check.


Aerosol can testing

Aerosol cans  are used across the automotive, healthcare and food sectors. Whether you work with monobloc, 2 piece or 3 piece aerosol cans, there are test and inspection devices for all of them.

There are aerosol can testing instruments that take the guesswork out of seamer setup, improve seam integrity and consistency, increase uptime, and make changeovers much faster. Why engage a range of handheld calipers, micrometers, and devices to gauge the key stats of their metal packaging, when an automatic ‘all-in-one’ system will measure all dimensions in less time than it would take you to open a can?
