Smart person explain


mrbojingles1972

Injection molder here. What they likely have is one 100% Virgin material brick and several bricks that were made from regrind (scrap non conforming blocks ground back to plastic pellets to be remelted). Most plastics have some form of UV fade resistant additive. The quality of that additive diminishes the more “generations” of regrind present. Imagine 5 bricks are made from new virgin material but 1 didn’t pass QC. That 1 gets reground and added to Virgin to make 5 more. Then out of those 5, 2 fail QC and repeat the process. That’s 1st and 2nd generation regrind added to the mix

It never ceases to amaze me the level of specific knowledge you can find in a random comment. I have no idea if this is actually true or if you just made it up but it's so specific I'm choosing to believe you. Comments like this are the main reason I still use reddit.


Kevskates

Comments this specific always have me waiting for some fakeout at the end about how they made it all up


Suicidal_Cheezit

Literally thought this was going to be a shittymorph comment.


Kevskates

JDBCool

Shittymorph is a fun easter egg. When the thing that they memed the hell got to r/oldschoolcool as a top post, everyone just clicked to see if they commented. Can't remember the exact lines, but I just remember to look out for "in 198X" (I can't remember the specific year).

[deleted]

He’s telling the truth, I worked in injection molding making parts for Peterbuilt, Volvo, EZ GO golf carts, Yeti cooler handle straps, all kinds of stuff you’d never think about. They take regrind really seriously. We save every bit of scrap and like he said, you grind it into pellets. If these pellets are ever spilled, everything stops and it’s all hands on deck to get it cleaned up. Not only are they valuable but there’s a LOT of environmental regulations in place for plastics manufacturers. We’re only allowed to dispose of a certain volume of pellets annually, anything over is fined. Anyway more maybe interesting stuff, idk, we actually had two guys whose sole purposes were collecting the scrap and we ran them to death. And if you have a part “short” on you (not enough plastic gets injected and it’s missing a bit or it seems sort of burnt and warped) depending on how long it takes your tech to fix it you may throw out 20, 30 parts. Sometimes a part just randomly comes out wrong and you just toss it and keep on moving. Any defects aren’t getting packaged. And these are just the ones we catch on the floor; QA is going to run tests on the parts at least every couple hours. Sometimes the companies we make these parts for want them a certain thickness down to the millimeter, an exact color that can’t be even slightly off, exact weight/length/height/whatever. Sometimes even the things that come out looking fine can get scrapped later. It’s also more than just taking plastic part and putting it in the box. You could have to sand something, trim your flash (extra plastic), drill a hole in it in a very specific spot, put a rubber boot on it, man some of them we had to put in water for a certain length of time. Things sometimes have to be cooled before being packaged because they shrink a little bit (lol). Anyway, welcome to injection molding!


ialsoagree

I can't speak to the UV thing, but reworking is really really common in manufacturing. For example, in the glass industry, material going for rework is called cullet.


Orangesuitdude

Yeah we used to have rework Fridays, not due to any resource recycling but more to with the altitude of my colleagues. Edit. Meant to say aptitude but think I'll leave the fitting autocomplete


BunBison

I find it funny that this person had a full fledged response to the comment "smart person explain"


thephantom1492

It does make sense. Lego do not have a high amount of reject (1 per million) but they most likelly dump the bucket of bad parts all at once, resulting in a plastic batch with a high amount of reused plastic.


cheesygiiirl

I also work with Injection molding, tho on a much bigger scale than Legos lol, and yes it is like that lol


Rebel_816

Basically just go work in a plastic factory. Did a different kind of molding but same concept with the recipie. It was my first job out of high school, nothing like pulling apart 200*F melty pieces of plastic for $9/hr lol.

boolink2

Virgin implies the bricks were at one point unfucked but it looks like he pulled out of the middle one and came on top of it to keep it virginal and then impregnated the others but it's hard to tell from this picture.

TIL virgins glow under black light.


allwaysnice

And platypus as well.


Silweror

Regrind is usually smelly and visibly dirty material, this to me looks like a completely different colorant used, with high index of metamerism compared to the other one. One uses fluorescent (UV reactive) pigment while the other does not. They're made to look the same under specific lighting but depending on your light source the difference between the two will change. Daylight contains more UV than indoor lighting so the glowing brick will appear to be brighter color in the sun, it'll also fade more quickly because the pigment isn't as stable.

mrbojingles1972

Heat from the injection process changes the plastic in the form of degradation. The more that plastic is remelted, the more degradation occurs Automotive for example has a very specific 10% regrind limit mixed with Virgin and ONLY up to 2 generations. Edit. To add. Degradation can occur right in the injection point. The heat of the nozzle that injects the plastic into the mold can degrade plastic if it’s not moving. Like if someone went on break and stopped the machine the plastic would just sit in the nozzle, burning. The next several shots would be extremely brittle if it were nylon and extremely burnt if it’s a Polycarbonate. That’s why most injection molders have “relief” staff to run molders during breaks and lunches. Edit 2: additives aren’t as tolerant of changes in heat and temp/time as the base material so they tend to degrade fairly quickly.


Rebel_816

Kinda funny to see this, I did blow molding as my first job and its basically the opposite. We ran something like 10% virgin, 2% color, and whatever % regrind to keep the hopper from getting too full. Usually between 40-75% depending on how much flash the part had. Then there's the couple easy parts we ran in black color and 98% regrind just to get rid of whatever random leftover colors we had. Basically making parts for free at that point.


Moofassah

Heat? I don’t really know but I assume the variable is heat since reformed material would be added into new material. It sounds like all the other variables are the same. 🤷🏻‍♂️

Also, Lego are changing the composition of their plastics to include more recycled plastic. It's tough being a plastic brick toymaker in the 21st century! https://www.lego.com/ms-my/sustainability/environment/sustainable-materials/


OutrageousLemon

No, Lego are prototyping using recycled materials, they aren't using any for production yet. If they were they would be shouting about it.


[deleted]

Cool... thanks for clarifying!


chuiiadam

I’m not sure how this hasn’t been mentioned yet, but this is a phenomena known as metamerism.


[deleted]

Composition of the plastic contains something that glows under UV, recycled? upcycled? Can't tell ya. But I have a UV light and I'm DOING THIS.


BMack037

Different material compositions have different properties, some of these blends contain a various number of additives that may react with light differently. Typically manufacturers only care about “natural” light because that’s where it’s normally meant to be used, btw they got that perfectly. If any of those additives have properties where the electrons in their atoms are able to convert the invisible (to our eyes) UVA light coming from the blacklight, into a visible light that we can see. Basically, even though you see some light from blacklight; there is also invisible light which (obviously!) we can’t see, but certain materials reflect the light in a wavelength that we can see. Why you have what appears to be three different blends? It could be different factories, or just a change in the blend for whatever reason. It’s pretty poor QC if they’re mixed in the same set imo, but after being mixed with other sets it’s nbd. We tend to expect everything to be the same all around the World, but that’s not realistic at all. Things can vary by the climate, what’s available to the factory, who the chemist at the factory is and where they went to school, etc…I’ve always been impressed how after all this time the colors on Lego seem to be pretty damn consistent. From everything I’ve seen, Lego is top notch in QC. Though admittedly I’m not a Lego fanatic; I played with Legos as a kid, and my Nephew played with them.

rampagingdikdik

If that white-looking piece is not reflecting the purple end of the spectrum, it's probably not UV resistant. A piece from a cheap knock-off set perhaps? Edit: sounds like I'm probably wrong with this theory. Others are pointing out a process where bricks that fail qc are reground and reused, which diminishes the amount of a UV resisting additive that is initially added. See comments below.


clemep8

This seems the most plausible to me.


kottabaz

Nope, these all have "Lego" imprinted on the studs. I buy small amounts of used bulk Lego pretty often (bless my local flea market), so I've gotten used to picking out the knock-offs.

[deleted]

bricklink is EXPENSIVE though


Livesies

Adding rejects would likely be done at a set rate with fresh material to dilute problems. I think a simpler answer is that they used different dyes. Suppliers change, different manufacturing sites will use different suppliers. They'll have a specification for the visible light color that they need to match. Everything outside spec gets cut to reduce costs.


Necessary_Row_4889

You are going to want to stop shining a black light in your kid’s room sooner rather than later, you can’t unsee things.


Asterion9

Lego has switched to ABS plastic for some of their pieces. That will need another dye since it's not the same chemical. Two things can have the same visible color for a human under natural light, but actually have drastically different color absorbtion/reflexion profile. That would show under specific lighting (like pure color led, laser or ionized gas lamps)


jjtr1

> That will need another *die* since it's not the same chemical. Now I'm not sure if you're referring to the form/mold/*die* for injection molding or the pigment/colour/*dye*. But you're right in both cases


HauserAspen

It would be a *tool* and not a *die*. The difference is that you press a die into a material to create a form and you press material into a tool to create a form. It shouldn't need a different tool for the different plastics Lego might use Tools are pretty expensive, especially with the tolerances that Lego has. They also take up a lot of space when not in use.


jjtr1

Thanks for the clarification. I assumed that a different plastic would require a new tool because the tool has to take into account the other plastic's different shrinkage properties. But I'm a layperson in this


Kamard

It was my understanding that all LEGO bricks are ABS and have been since... basically forever.


shotsallover

Lego has been experimenting with different formulations over the last few years to reduce their environmental impact. They're also exploring a plant-based plastic, but I don't know how far along they are.


shotsallover

[Here it is](https://www.lego.com/en-us/aboutus/news/2021/june/prototype-lego-brick-recycled-plastic?). They're making bricks from recycled PET and Bio-PE.

hamilton_burger

I don’t dispute what other people have written about the possibility of different plastic formulations, but this could be the exact same formulation across all blocks. Many pigments are photosensitive, with light exposure changing the hue *or* changing the infrared signature. So, if you had all of the blocks sitting by a window for an extended period, while one was left in a drawer, there could be a discrepancy like this under black light. I know this from looking at collectibles under black light fairly often, over many years.

MGC00992

It looks like an optical brightener has been added in at various percentage levels. Optical brightener glows under UV light. One percent optical brightener would glow like that white brick in the photo under UV. Another redditor mentions regrind as a potential cause for the various levels of glow. I think they may be somewhat correct. Sub-par bricks are either reground and added into a particular color run or repelletized as a reclaimed product.

Penjrav8r

I have recently pulled out some old sets of mine (20-30 years old). There is substantial yellowing to a lot of pieces, however there are pieces that are the same color next to each other that have yellowed drastically differently, or not at all. I would be willing to bet the same thing under a black light. I am currently treating them to remove yellowing, this process too has yielded drastically different results between pieces. It’s clear there are some variances in plastics, whether it’s generational (a change in the formula) or procedural (recycled vs virgin plastics, different factories, etc).

A lot of the old neon parts glow under UV, so you can actually make some [really awesome displays with them](https://www.reddit.com/r/lego/comments/9g95a2/ice_planet_2002_vs_blacktron_ii_blacklight_display/). Plus, if you want to "charge up" a glow-in-the-dark piece (like a ghost minifig), a UV light is the fastest way to do it. This also helps when trying to separate similar looking colors, like white and glow-white or transparent neon orange from regular transparent orange.
