Who We Are

Innovators, Leaders, Manufacturers

Challenge RMF, Inc. is the world leader in massage technology for the further processing of value added meat muscle products. It has been our sole business to provide food machinery innovative in design and superior in craftsmanship and performance.

Together with our RMF family of companies, our team of engineers, technicians, and industry experts, we stand ready to deliver a single unit or design and equip an entire plant.

Challenge RMF massagers are built to outperform and outlast all others. Serving as a testament to our quality, durability, and success: the first Challenge Massager built and installed in 1980 is still performing and in use today!


With its inception in 1980, the Challenge Massager revolutionized the meat and poultry industry with its extraordinary design and unique “meat-on-meat” massage. Inspired by the needs of leading processors, the patented design created by Bruce Gould of Challenge Cook Bros., Industry, California, quickly elevated Challenge to its leading role in massaging technology based on quality construction and superior results.

Special Partnership

A partnership was formed with the food machinery specialists at RMF Steel of Grandview, Missouri in 1988 when Mr. Gould and RMF owner John Robertson joined together and created Challenge RMF, INC. Today, this outcome shines in Challenge RMF’s quality products, service, and the gratification of hundreds of loyal customers, suppliers, employees, and representatives worldwide.
