Molding the Future, Sustainably.

HARBEC, the plastics division of ADDMAN Group, offers complete part manufacturing support, spanning prototyping to end-of-life solutions. With a heavy concentration in injection molding, we also help customers with additive manufacturing, CNC machining, and engineering. All of this is done with sustainability in mind.

Certified for Your Exacting Applications

HARBEC is an AS9100 and ISO13485 certified and ITAR registered contract manufacturer of tight tolerance precision 3D printed metals and plastics, machined components and assemblies, and injection molded components and assemblies. We are committed to advanced technology, product development, quality management and continuous improvement.


Our new 630A is an Arburg all-electric, 270-ton (U.S.) injection molding machine. The platen size is 35.43” x 35.43” in height and width, with 51.18” of maximum daylight. The injection system ordered with the machine features a 70mm screw with a shot size of 34.7oz.

Specialty features ordered with the press include an integrated hydraulic system for the operation of hydraulically actuated mold mechanisms and motors, an integrated hot runner control system, and pre-installed interfaces to support mold or ancillary monitoring devices.

Our targeted application for this press is mid to high-level production volumes. It was ordered to support our production ramp-up for a new customer and also fill a rather large tonnage gap in our injection molding machine lineup.
