The Gizmodo technology blog has posted some fascinating videos from a tour of Lego A/B's Billund, Denmark, headquarters plant. The videos posted today include the plant's material handling, tooling, molding, decorating, packaging and warehousing areas.

This tour offers a great example of a highly automated injection molding plant. I'm sure many molders -- and equipment suppliers -- who read this blog will want to take a look.

Gizmodo senior associated editor Jesus Diaz notes in one post that the videos offer a rare opportunity for viewers to witness a look at the inside of Lego's HQ plant without any barriers or secrets.

The timing of his trip is interesting, considering that Lego recently announced that it is bringing more of its molding work back in-house, after several years of outsourcing it to Flextronics International Ltd. A Lego spokeswoman told Bill Bregar, our senior reporter: "We think we could obtain more cost reduction through doing this ourselves."

After seeing the inside of the Lego plant, it's hard to imagine another supplier can make Legos a lot more efficiently than the experts in Billund.
