ANAHEIM, Calif.—Freudenberg Medical is expanding both its thermoplastic and silicone molding capabilities in the U.S.
The firm has added equipment to its California operations in Baldwin Park and Carpinteria, both designed to enhance the firm's capabilities in micro-molding.
"There's a continuing trend toward miniaturization," Freudenberg Medical CEO Max Kley said at MD&M West in Anaheim. "As you go deeper into the body and integrate additional functionality, parts have to be smaller. You have to compress more into less space."
The firm's Baldwin Park site, which focuses on thermoplastics, added an Arburg micro injection modular machine and supplemental equipment including robotic part handling and integrated vision inspection systems for process control and monitoring in-cavity pressure transducers. The site also is expanding its tooling capabilities.
The machine allows Freudenberg Medical to produce very small, accurate shot sizes, a key challenge when making micro-molded parts.
"The precision of getting these small shot sizes right is a big challenge," Kley said. "But it's also things you might not think of, like handling the part afterward or de-molding. The parts are so small, you have to be able to de-mold them and deposit them in a controlled way. And then you have to have the metrology in place to do the quality inspection."
