Molding Co. of Farmington, Mo., has become the first licensee for a technology promising major change for rotational molders.
Use of the transfer rotational injection process "allows you to rotational mold parts you couldn't before," Barney Grosberg, vice president of sales and marketing, said in a telephone interview.
The firm agreed April 11 to purchase the one-time license from SLF Industries Inc. of Tuckerton, N.J., and pay royalties on parts built with TRIP technology.
SLF, a Virginia corporation, was created to handle the licensing function. SLF principals include inventor Craig Wallin, marketing consultant Donald Schraegle and an unidentified end user.
Wallin owns rotomolder Sirtec North America Ltd. Inc. of Logan, Utah, and has applied for a U.S. patent on the moving-mold TRIP technology.
TRIP evangelist Schraegle has been negotiating for licenses with three original equipment manufacturers and five rotomolders, in addition to the Missouri firm. Separate TRIP agreements are offered to OEMs or processors.
Using molds with moving sections, TRIP has some major OEMs considering first-time use of rotomolded parts, Schraegle said in an interview following a March 20 presentation at the Association of Rotational Molders conference in San Diego.
The interested OEMs make medical products, trucking components and automotive parts. Each could buy a license here and use it overseas.
"It is incredible the number of applications we are uncovering as we visit rotational molders and OEMs," Schraegle said. "Companies that have stayed away from rotational molding now can get a product where they have injection and blow molded quality."
Initially, Schraegle said he has targeted a dozen rotomolders "of a mind-set that the technology is something they understand and can use in their operations." Licensing OEMs is "a little slower because it has to go through engineering and then management people to see where it would fit," he said. Schraegle operates through SJS Industries Inc. of Medina, Ohio.
Two incoming jobs at the new licensee might use TRIP for a truck windshield-wiper container and a boat waste-containment unit, Grosberg said.
