Rapidwerks LLC, a Chicago-based company specializing in micromolding, rapid prototyping, tooling and complex assemblies, is using a Microsystem 50 molding cell from Battenfeld Injection Molding Technology, Austria, a division of SMS Plastics Technology Group.
The all-electric injection press uses a plunger injection system that permits tiny shot weights from 25 milligrams to 1 gram. The injection speed is 30 inches per second, a key when making parts such as watch gears that have fill times as low as 0.14 millisecond.
Because of the very small shot weight, the Microsystem 50 generates much smaller sprues and runners than conventional presses that have been modified for micromolding, the firm said.
Rapidwerks is a division of Stratos Lightwave Inc., a Chicago firm that makes optical subsystems for data networking, storage and telecommunications. The molder also targets the medical-device and automotive markets.
Battenfeld, based in Meinerzhagen, Germany, has its U.S. headquarters in West Warwick, R.I.
