Precision contract manufacturer Medbio Inc. is expanding its micromolding capabilities for implantable devices by adding an Arburg all-electric injection molding machine with a micro-injection module.
“We have been successfully molding very small, intricate components for years, but the medical-device industry is designing smaller and smaller devices,” said John Woodhouse, sales and marketing manager, in a news release.
Woodhouse said the company will move its implantables business, and the new press, into the new molding cell in its Class 10,000 clean room in Grand Rapids, where the company is headquartered and has its manufacturing.
The company now has 15 Arburg presses, with clamping forces of 17-165 tons.
The new Arburg module provides extremely small shot weights, between 0.05 gram and 1 gram. It operates with an 8-millimeter screw and is combined with a second screw that prepares and feeds the melt.
The modular platform allows for a series of standard quick-change screw sizes all the way up to 25mm, and a shot-weight range of 0.05 gram to 36 grams.
The 8-year-old company has a Class 10,000 clean room for assembly, a Class 100,000 clean room for molding and an isolated clean room for molding implantable resins. It currently molds implantables, surgical disposables, diagnostic, and instrumentation components for the orthopedic, cardiovascular, ophthalmology, neurology, and biotechnology markets.
