As microscopic injection molding experts, Accumold constantly works under the hood of each project, ensuring clients complete their goals without compromising project integrity. Accumold is a very good partner of WT and regularly exhibiting at WT | Wearable Technologies Conference Series.

Micro mold parts can be found in microelectronics, cell phones, telecommunications, surgical tools, hearing aids, medical devices, antennas, connectors and more. Locking features are often essential when looking to overmold or insert mold into one or more other components. This feature is easy to forget, yet can cause a lot of rework if not caught up front. Locking features are intended to hold the overmolded component to the substrate.

“Because we’re dealing with such small and tiny parts handling oftentimes can be a challenge. Environmental factors like static can sometimes cause parts to float away. So you must have a very controlled environment in order to handle some of these micro parts,” Aaron Johnson Vice President of Marketing & Customer Strategy at Accumold, told WT | Wearable Technologies in an interview. “You also have to have some in ingenuity when designing automation systems for inspecting or handling them for packaging. It’s also very helpful to coordinate with your customer on how their incoming inspection will qualify and verify product. Correlation between measurements when you’re only dealing with a few microns becomes very critical.”

Accumold is recognized as world-class, high-tech manufacturer of precision micro, small and lead frame injection molded plastic components. The company has been an expert in micro molding for more than three decades—and many of their professionals have served the company their entire careers.

Micro molding, used by many medical device OEMs, is the tiny-scale molding form of injection molding that requires developing a cavity to match the shape of the part you want to make, sort of like the plastic molding that makes Lego bricks. Micro mold parts can be found also in microelectronics, cell phones, telecommunications, surgical tools, hearing aids, medical devices, antennas, connectors, etc.
