BUTLER, Wis.—Molded Rubber & Plastics Corp. has taken what it believes to be a gigantic step forward in refining its molding processes.
Executives from the company that began 93 years ago as the Unbreakable Button Corp. say that the firm's commitment to the discipline known as scientific molding process development has improved production at a plant already known as a leading producer of components and devices for the medical marketplace.
Scientific molding helps to ensure complete control over the injection molding process by focusing on the chemistry and composition of the material used, rather than just the machines utilized to create the components. This process demonstrates that the molder adheres to an established set of principles throughout the process, an important attribute particularly in the production of medical components, where stringent requirements are in place.
Manufacturers have practiced scientific molding for years, according to the company. It originally was intended for the development of molding processes with thermoplastic injection molding.
MRPC has expanded the practice to include all molding processes.
“We see that as a necessary natural evolution of the industry,” said Jeff Randall, vice president of engineering at the firm. “The scientific molding approach allows you to develop more robust and repeatable molding processes.”
He said his company takes a more holistic approach to scientific molding.
“We also use the principles during the tooling design, during product design, during material selection, all the way through the process,” Randall said. “Not just for thermoplastics, but for any part that we're going to be manufacturing.”
