What's the word on rotational molding? More.

For rotomolders, this year's ranking research for fiscal 2021 shows, well, more. Like larger volumes and higher prices. The average sales per company is up 15 percent. Polyethylene pricing was up 17.5 percent, contributing to material costs pass-through gains. The total related sales for our 106 ranked firms is $2.9 billion, up 14 percent from last year.

Proprietary molding takes the largest share, which is what we expected, with 55 percent of the total sales, representing the brands that make products like tanks, carts, toys, kayaks and playground equipment. Our 1999 ranking had this group at 62 percent of the total. Custom molding runs close behind with 41 percent of this ranking's total sales.

Captive molding comes in at just under 5 percent. This group represents those manufacturers who rotomold a component or part of their finished product, like machine housings. This is the most difficult sector to explore because most firms don't consider themselves rotomolders.

So, what's the biggest news?

Tank Holding Corp. acquired Dutchland Plastics LLC earlier this year, giving Tank the largest dollar gain in our ranking.

Ranked at No. 4, Centro Inc. has a new plant in Iowa, expecting production to start next February.

Custom rotomolder Solar Plastics LLC, which ranked at No. 11, has started up production in Monterrey, Mexico.
