I’ve had a number of people ask me about a perceived quality issue lately: If
you take a number of plates and create two or more large stacks, they tend to
be differing heights. For example, Ben has posted some photos here:

I mentioned that this is a “perceived” quality issue because on the surface
it seems to be an obvious quality issue, but in reality, there is nothing out
of place. I have checked with our Quality Assurance department for some
details and they have passed along some info.
When you build, the height difference will often be aligned as the elements
typically will vary in element height from one end to another. In order to
get the maximum deviation all the plates have to turn the same way and they
have to be from the same tool. This is not likely.
The height measure on our plates is 3.2 +/-0, 1 mm. With a height difference
up to 0.2 mm per plate it will be approx.
|
Or >6%. I “perceive” that as being quite high(?). ;)

4.0 mm. If you build 20 plates
above each other. On the photo the difference is under 2.0 mm.
Consider that in the official LEGO models, the LEGO designers never use more
than three plates in a stack. As a model is built, the elements will equal
out and create a solid model regardless of these very very minor tolerance
changes (+/- 0.1 mm), creating a very stable model.
The tolerances used today are the same as years past.
|
Surley advances in technology should have enabled tolerances to be improved?

Hope this helps clear this up. Please know (and remember) that LEGO has
always been, and will always be about quality. We have a great team in the
Quality group, manufacturing, and Design that works hard to ensure the best
parts are being created.
Sometimes there are mistakes or problems, but as you all know, those times
are rare. And unwelcomed... thus the desire by the entire company to ensure
they never happen.

I feel a group hug coming on.
