Inside the Lego Factory 260

An anonymous reader writes "Gizmodo has a fascinating report and video tour inside the Lego factory, which is full of robots and controlled by a mainframe. 'This video shows something that very few people have had the opportunity to witness: the inside of the Lego factory, with no barriers or secrets. I filmed every step in the creation of the brick. From the raw granulate stored in massive silos to the molding machines to the gigantic storage cathedrals to the decoration and packaging warehouses, you will be able to see absolutely everything, including the most guarded secret of the company: the brick molds themselves.'"

    • It seems lego has been moving more and more over my lifetime of 27 years from interchangable brick type pieces to specialized pieces of plastic that are really only useful with the original kit.

      Granted I haven't purchased a pack in 15-odd years, but when i look at them at the store, many of the pieces are very specialized.

        I hit my LEGO peak about 15 years ago, when Castles (Knights, Woodsmen, Dragons) were the rave. I recall getting a full castle set and integrating the pieces into larger, more substantial castles. The pieces were very specialized (i.e. parapet pieces, pre-built castle walls) but what this did is allowed me to construct more elaborate add-ons since I didnt have to exhaust my regular pieces on building spires, walls, etc.. So yes, I would say even 15 years ago the sets were certainly specialized, but you could really use it to your advantage. My nephews and nieces now play with my old stuff and I find their newest sets are even MORE specialized, but yet again, they use it in a similar manner when I was a kid. Speaking of which, I have a 1 month old so I have to make plans on getting my lego back for my little one!

        People were complaining about specialty pieces when they started making spaceship canopies and castle wall pieces. I picked up a couple of the big Bionicle robot sets a couple years ago, and they do have a lot of new pieces. All of them are compatible with older bricks, but they wouldn't be terribly useful unless you're building a Bionicle style robot. The main difference is the sets are based more on axles, hinges, and ball joints than bricks.

    But this still doesn't answer the "Why is Lego so expensive?" question that I've always had ever since I was a kid. The materials can't cost that much (Obviously petroleum byproducts cost more now than they did 15 years ago, but still...). Also, those looked like injection molds - which AFAIK are one of the cheapest ways to manufacture something. Don't get me wrong - I love, love, love lego. I was just always sad as a kid that I didn't have money to buy more.

          That's not really true. Process engineers have a lot to do with the quality of plastic products. Those big injection molding machines are really finicky about temperature and pressure, and the molds have to be designed very well. Otherwise you'd get legos that shrink too much, or not enough, or worst of all - not consistently.

          Legos have to strike a delicate balance between fitting too tightly and too loosely... it's actually amazing that all of the sets over the years are pretty darn compatible. It's the rare Lego that simply falls off.

          Plastic quality is also important, but presumably they are just buying some standard high-quality type. (Maybe not?)

              If you buy the cheaper competition, you'll quickly see how much Lego's focus on Quality Assurance matters. It's not unusual for the cheaper knock-offs to have a few bricks in each set that simply don't connect at all to the others.

              And those are all from the same batch - I doubt that year-to-year, or decade-to-decade, compatibility is even on the roadmap for those products.

      The big deal (according to someone at the company in an NPR interview, I believe) is repeat customers. Since their product is so durable, customers tend to buy until they have enough then use them for a couple generations (I know my legos will be used by my kids someday).

      None of which alone explain it, but can add up.

      They are very particular about the ABS they use - it has to be metals-free, historically not very easy - which used to be supplied only by Bayer (until around 1998, LEGO US was still shipping ABS pellets from Germany to Enfield CT - one worth-his-weight-in-bricks engineer got GE Pittsfield MA to spec the plastic, saving them some bucks).

      The bricks IIRC are build to a tolerance of 3/1000ths of an inch. Look at bricks and try and find the gates (where the plastic in injected and detaches from the flashing) or the knock-outs (where a part of the molding machine pushed the brick out - typically these are obvious kludgy bits of a plastic toy, in LEGOs they are all but invisible) The LEGO engineers used to smile a lot as other companies' engineers searched, often in vain, for these tell-tale machine marks.

      In Enfield they have a lego-brick knight statue commemorating their ISO 9001 certification. Not so sure how many toy factories hit that mark.

      For a long time the place was rather labor-intensive. A 1990 tour had more people on the packing line and a series of lights to alert someone on the floor (who had to be in sight of the molding machines) to a malfunction. The same tour in 1996 this was replaced by a pager system. In all that automation, they prided themselves on never letting someone go from the factory when their role was replaced by a machine -they always had something new to be done based on a lot of R&D. Haven't been there since 2000, but I understand that pattern was pretty much unbroken.

      At least in Enfield, the factory was nearly as as spotless as the HQ office buildings. I doubt every plastic-toy-cranking factory elsewhere in the world has that level of upkeep, and it's not cheap.

      Making the rafts of tie-in toys means paying royalties to Star Wars, Harry Potter, etc. While base sets might cheaper at WalMart now than they were at a boutique toy shops a few years back, the brand name additions likely helped keep prices off the bottom.

      Enfield CT likely isn't the cheapest labor market around, which explains why, sadly, a year ago the last nut and bolt of the factory were shipped off to Mexico. Blasted sad. A great bunch of people up there.

      1. They're expensive because they are built to a much higher level of quality than is typical for injection-molded plastic toys.

      Have you ever seen a defective Lego brick? Or heard of a set with a missing piece? A lot of work (and expense) goes into avoiding that. Hence all the automation - if they had humans doing all that work, Lego would be even more expensive.

      The bricks themselves are little marvels of engineering - they use extremely heavy, multi-piece molds, and sophisticated molding machines to keep the dimensional tolerances to within (IIRC) .001 mm.

      2. They're expensive because they're very durable.

      Despite the relative cheapness of the plastic material itself, you can easily find Lego that's 30 years old, has been played with by dozens (or hundreds) of kids, snapped together and apart thousands of times, and still functions perfectly.

      Given that they basically don't wear out, Lego bricks are priced higher than they would be if they were intended to be replaced from year to year.

      3. They're expensive because people are willing to pay for them.

      As a result of #1 and #2 above, Lego has a well-deserved reputation for quality. Despite plenty of lower-priced competition, Lego continues to sell well.

      You can even buy bricks that are inter-operable with Lego for literally 1/10th the price, and they still don't out-sell the real thing. Why? Because they're simply not made as well - they don't stick together or come apart as well as Lego bricks, and they aren't nearly as sturdy.

      Even as an 8-year-old, I noticed that the knock-off blocks were not worth building anything out of, and quickly separated them from my "real" Legos.

      Interestingly, sets on ebay often go for an appreciable fraction of the price they originally sold for, or more than the original price for some of the really good ones. I can't think of many other toys that hold value or even appreciate in that way, insane Star Wars memorabilia, etc. notwithstanding.

  • this still doesn't answer the "Why is Lego so expensive?" question

    C'mon - seriously? Why does Starbucks coffee or Coke cost the consumer 25x the cost of the ingredients? Why do baseball cards cost 50x the cost of the paper and print?

    It's all BRAND. You're not paying for the plastic - you're paying for the TV commericals, the packaging, the crappy Star Wars licensing fees and even the salary of the PR flunky who gets this crap posted on SlashDot.

  • a boy can never have too many LEGO bricks. Parents tend to feel otherwise.

    Almost 2 decades ago I worked in the color lab of one of the suppliers of the plastic granules that LEGO uses, and I can tell you that even then, LEGO had about the most tight color and quality control in place I've ever come across. That's probably why a new brick and a brick bought a decade ago are still so much alike.

    I remember that most of that production was checked in double tact: twice as often during a run then any other plastic, and that included metamere checking (ensuring that the color also changes correctly when you switch from daylight to artificial light - not always a given as every pigment you use can act differently).

    I've not been involved in developing the LEGO color recipes, but hats off to whoever did them from their samples - that must have taken at least a week. New stuff like matching the color of the leather going to be used in car seats was easier IMHO (although also challenging, precisely because of the metamere issues). But it was fun, albeit occasionally dangerous work, in those days some of the additives were highly toxic..
