Three-shot designs boost usability of drug delivery devices


Medical device OEMS are looking for new designs for drug delivery devices that make them easier to use while also reducing assembly and other manufacturing costs.

That's according to Bill Welch, chief technology officer at Phillips-Medisize (Hudson, WI), who discussed medical device design trends in an interview with PlasticsToday.

The concept has moved beyond pen-type injection devices to include inhalers and patch-type approaches.

Phillips-Medisize is expanding its ability to make specialized medical devices by developing two-, three- and even four-shot molding capabilities that combine structural thermoplastics such as polycarbonate/ABS with a flexible elastomer and other materials that can provide watertight seals or other capabilities. One specific area of growth is liquid silicone rubber (LSR) overmolding....
