Romeo RIM Produces Bayer's PUR- & LFT-based Agricultural Combine Side Panel Prototype

Published on 2014-10-30. Author : SpecialChem

ORLANDO -- Since bringing the Long Fiber Technology (LFT) process to North America 14 years ago, Romeo RIM has continuously looked for opportunities to advance the technology and meet the evolving needs of the marketplace. Now, they've done it yet again.

Using LFT and polyurethane products supplied by longtime collaborator Bayer MaterialScience LLC, Romeo RIM has produced a prototype agricultural combine side panel measuring 111"x73"x5" deep. According to Romeo RIM, the component creates a shielding system with a value proposition focused around cost and weight savings when compared to alternative materials, such as sheet molding compound (SMC).

The prototype combine panel was on display at Bayer's booth (3145) at CAMX in Orlando.

"What makes this part so attractive is the value proposition we're able to offer," said Matt Getty, director of engineering, Romeo RIM.

Getty explains that a part made using polyurethane and the LFT process can be up to 40-50 percent lighter than SMC parts while still having similar mechanical properties. He goes on to state that another benefit of utilizing the LFT process is the ability to produce a high-gloss surface right out of the mold, which eliminates the need for secondary painting operations, saving valuable time and reducing labor costs.

The combine prototype panel is produced utilizing a 400-ton, 12'x12' double shuttle press, which Romeo RIM believes to be the largest LFT press in the world. For structural support, the combine panel features molded-in ribs two to three times the nominal wall thickness with little to no read through on the A surface, according to Romeo RIM.

In addition to supplying polyurethane products, Bayer contributions included on-site technical support of the product development, led by Romeo RIM, to make such a large part. Support to achieve a high-gloss finish was provided through Bayer laboratories in Pittsburgh, while design assistance to meet the structural integrity and mounting requirements was provided by Bayer's engineering group.

"Bayer was with us every step of the way," Getty said.

"We've been collaborating with Romeo RIM on an ongoing basis as they continue to take LFT to the next level," said Paul Platte, market manager — Polyurethane Composites, Bayer MaterialScience LLC. "This latest accomplishment is a game changer for OEMs looking to produce very large, high-quality, structural parts more quickly and inexpensively."

LFT: An efficient, economical, automated process


During the LFT process, long glass fibers are chopped and injected into an open mold along with polyurethane resin in a one-step process. A fiberglass chopper is attached to the polyurethane dispensing mix-head, which is attached to a robot. The robot is programed to move over the open mold cavity while simultaneously dispensing both the long glass fibers and the polyurethane resin in an open-pour method. At the end of the pour, the mold is closed and the part is formed.

Use of a sprayable in-mold coating, also provided by Bayer, results in an agricultural Class-A surface right out of the mold. In addition to the agricultural market, large, Class-A surface LFT parts are also well suited to building and construction, mass transit and heavy trucks, among others.
