Rotomolds and Your Garden


My father loves to garden; he even has his Master Gardener certificate. I am not exactly sure what that means, but I think it is probably indicative of his ability to make anything grow anywhere. He is capable of growing tomatoes so large they split their own skin. His back yard is faviconpractically a jungle with green growing everywhere. Sadly, I do not think I inherited a genetic disposition for growing anything, so when I visit I just stare at all the greenery in awe.

One day I noticed his distinct lack of typical yard decorations like pink flamingos and garden gnomes, and I mentioned this to my dad. He grunted and made some crack about not wanting that kind of stuff in his yard. Having learned what I have about plastic yard decorations, I explained to him these gems of Americana are not just “stuff,” but are instead products of an intricate process called rotational molding.

I told my dad how rotational molding works, being careful to explain that rotomolds are the casings out of which plastic products like pink flamingos come. Manufacturers of plastics that use rotomolds pour plastic resin into the mold and then heat it slowly, being sure the mold rotates as it is heated. Recognition registered on his face when I told him that lawn ornaments are strong and durable because of rotational molding. He said something like, “So that’s why it’s so hard to break them.” Yes, dad, that is exactly why. Products produced by rotomolds have a high level of integrity because of the nature of the rotational molding process. As the resin heats and becomes a liquefied plastic, the turning mold evenly distributes the plastic inside, ensuring even coating. What you get is a plastic product that is of equal thickness throughout, and this makes the product extremely durable. Despite all my explaining, my dad still was not going near a plastic garden gnome.
