Moulding Machines Value (New/Sealed)

This chart represents the current new/sealed value of the set Moulding Machines since May 2018. Medium accuracy

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.

At around $2,513 for a sealed copy, Moulding Machines has averaged 27.9% a year since retirement. Our forecast sees it reaching about $2,804 within five years. The average used price is $2,086 for those in good overall condition.

Collector and Investor Standing

Made only for guests of the LEGO Inside Tour in Billund, Moulding Machines has the kind of backstory collectors notice. Small production and a subject close to LEGO itself make it much sought after, while limited investor interest and rare sales leave it on shakier ground there.

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.

“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.”

Full review at www.eurobricks.com

“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.”
