LEGO 4000001 Moulding Machines is an Exclusive / Inside Tour set released in 2011, containing 795 pieces. It was distributed to attendees of the LEGO Inside Tour held in May 2011, with only 68 copies produced. The set includes two detailed brick-built models representing different eras of LEGO molding technology: an early manually operated plastic injection molding machine from the 1940s–1950s, and a modern ARBURG injection molding machine from the 2000s. The models highlight the evolution of LEGO’s production process, reflecting the company’s transition from early plastic part manufacturing to contemporary automated systems used in Billund and other LEGO factories.

A new and sealed Moulding Machines is currently valued at around $2,147, with annual growth of about 28.1% that is expected to level off to around 9.5% in the coming year, making it a solid investment. The average used price is $1,782 for those in good overall condition. Based on current trends, this set could be valued near $2,324 within the next year.

Moulding Machines is a relatively rare set. We have not seen set 4000001-1 for sale in primary or secondary markets for over 6 months. Its market value is likely somewhat higher than our estimate. The last brand new Moulding Machines was sold on eBay.

There are currently no new/sealed listings available for Moulding Machines at this time.

Insights

Released in 2011 as a LEGO Inside Tour Exclusive, Moulding Machines carries factory-heritage interest and exceptional scarcity from its limited attendee-only distribution, and persistent but infrequent demand has produced volatile trading and constrained liquidity for collectors and holders.

Set Facts

Only 68 copies of this set were given away.
The smaller model, which is the manual molding machine, includes two interchangeable molds, one with red and the other with blue elements being molded.
The set was later re-imaged as 40502-1 The Brick Molding Machine which was a LEGO House exclusive.
The set includes 2 models of molding machines, the newer machine form the 2000s is an ARBURG Allrounder 370S-700 injection molding machine. The ARBURG is a high-precision, industrial machine designed for the production of plastic parts. It's utilized by LEGO to manufacture the various plastic components that make up their building sets, ensuring consistent quality and precise dimensions essential for the interlocking brick design. The smaller model is a hand-based machine used in the 1940s and 50s.
Moulding Machines was designed by LEGO designer Mel Caddick.

“What really stuck out for me during the build was the attention to detail - even for parts that are hard to see. For instance on the larger Molder Machine - the mold has some nice work - simple cheese wedges - but much better than say simply tiling it. was also impressed at... More the accuracy of it, when I saw the box art, it's instantly recognizable as THE molding machine.”

“The Molding Machines set is certainly one of my favorites. It has two models: a manually operated machine from the 1940s/50s, and a more modern 2000s era machine. Both models have some limited play functions, which adds to the designs.”
