Rotomolding by the numbers

Comments Email Print

This week's Plastics News has our annual ranking of North American rotational molders. Here is a look behind the data.

This year we're ranking 122 firms, with rotational molding sales of $2.36 billion. That is higher than last year's total by just under 1 percent.

It is interesting to examine the annual totals over the last few years. $71 million was added for the 2014 fiscal year and $17 million for fiscal 2016, still growing but at a slower pace. The average sales per firm is also still growing, $18.5 million then compared to $19.3 million now.

For those firms reporting sales growth, the average increase was 23 percent, but with a wide range of 3 to 100 percent.

Most notable in this year's listing are the acquisitions, both for private equity and consolidation. In fact, 8 percent of our ranked firms reported some type of sale during 2016.

We said goodbye to Englehart Moulding Corp., which stopped production mid-2016 so that Rick Englehart could retire, and hello to Simplay3 Co. of Streetsboro, Ohio, so that Tom Murdough could unretire.

These are the fastest moving companies:

• Michael Bros. Inc. of Prescott, Ariz., moved up seven spaces to rank at No. 89.

• Allied Resin Technologies LLC of Leominster, Mass., moved up six spaces to rank at No. 105.

• Custom Roto-Molding Inc. of Caldwell, Idaho, moved up six spaces to rank at No. 68.

• Endurequest Corp. of Porterville, Calif., moved up six spaces to rank at No. 104.

• Faribo Manufacturing Co. of Faribault, Minn., moved up six spaces to rank at No. 94.

• Rochester Rotational Molding Inc. of Rochester, Ind., moved up six spaces to rank at No. 94.

• Carris Rotational Moulders Inc. of Aurora, Ontario, moved up five spaces to rank at No. 114.

• Roto Plastics Corp. of Adrian, Mich., moved up five spaces to rank at No. 101.

• Wes Industries Inc. of Princeville, Quebec, moved up five spaces to rank at No. 111.
