The German parent of Arburg, Inc., Newington, Conn., has come out with a new micro-injection module that can be mounted on a standard machine base and also can be removed quickly to allow the press to be returned to conventional molding. The retrofittable module is designed specifically for use on electric Allrounder A machines with a size 70 injection unit. The two-stage system uses an angled screw of 15 or 18 mm diam., with its own servo-electric drive, to melt standard-size pellets and feed the melt to a horizontal injection screw of just 8 mm diam. It has a shot capacity of 2.3 cc or 2.3 g PS. Both screws are just 8D long. A filter at the end of the first screw prevents any unmelt from reaching the second screw. There is a quick-reacting, short-stroke check valve on the injection screw, which has a 10-mm
stroke on a 0.5-cc shot. The micro-injection system is said to provide first-in/first-out performance for minimum residence time.
