A simple quality check is to have a powerful fan blowing onto the conveyor belt. All empty cans will be just blown away*. * This is not my idea. I heard this a few years ago, with respect to finding empty boxes in the soap manufacturing industry.
It doesn't always work - not all lines have a single lane. Also ,as I wrote a couple of posts ago, there are conditions when line pressure is high and empty cans are kept pressed between full ones.

Loaded a case of diet coke into office refrigerator and found this: an unopened empty can. How could this pass the quality control?

From the mid 80's to the mid 90's, I worked at a cereal manufacturing facility. Each carton was checked for weight, and if underweight, the air 'pushed' it off the line. As others have said, quality control is important, as long as it doesn't overtly affect profit. If a customer found a 'lump' of cereal in a box, they were asked to sent in the box top (to identify the production date and line) and would receive some coupons for free product. Could quality control have prevented the 'lump' from reaching the production line? Yes. But, the cost could probably be more than the lost sales, so not economically viable. For those that did send in the box top and get the coupons, there may be a sense that 'the company cares' and a customer is retained.

From the mid 90's the X-Ray vision technology gradually took hold, lumps are now something usually avoidable (at least to the customer). Still many customers are approaching the solution only recently, after having been bought by big brands which need to retain a good name, some country legislations or simply because they must renew the lines for other reasons and they decided to improve (and in many case be cost effective if they can concentrate different quality checks in a single machine).

They do. They simply go too fast for checkweighters to be useful.

They're also doing so, each year they buy a freaking lot of new machines to substitute those that they can - sometimes though their production environments are too cramped and can't accomodate different machines unless they redesign the whole chain. so not all factories have the latest QA machines.

OK, so weigh the six-pack or the 24-pack or whatever. A difference of 330 grams in the weight of those should still be easily detectable, and require much fewer weighings. Your comment about the space on the production line makes sense; redesigning an entire factory layout in order to remove a (presumably tiny) number of errors is probably not at the top of their list... :)
If you have an important point to make, don't try to be subtle or clever. Use a pile driver. Hit the point once. Then come back and hit it again. Then hit it a third time - a tremendous whack. --Winston Churchill

Yup. Process-control engineers certainly earn their pay!

Phht, it's diet coke - hows a programmer supposed to work without energy to keep his brain functioning? some already mentioned the empty makes it super-diet another benefit is less weird sweetner chemicals win-win now go and buy proper coca-cola.

Version 3.3 of the automation code was written by someone who only drinks vegetable juice. So of course it had a bug.

I guess you found the only can which was really "diet" :)

Not at all.. the can with just air in it is only 0 calories, whereas the one with cold diet soda in it is negative calories.
I live in Oregon, and I'm an engineer.

Perhaps there was a tiny leak in the can.
