The Rheo-Pro M05VG multi-tip valve gate hotrunner by Mold Hotrunner Solutions Inc, Georgetown, ONT, is for molding direct gated micro parts.  It distributes melt through tight, circular clusters of six gates per nozzle. An X-shaped hotrunner manifold system with four nozzles, for example, will feed a 24-cavity mold. The extremely tight gate spacing offers the most compact mold design for micro parts. This is important because it reduces the melt residence time for sensitive molding materials like POM, PC and PSU. The M05VG can direct valve gate micro parts with a weight of less than 5 mg. It delivers clean gate marks of 0.7 mm to 1.0 mm diam with zero gate vestige. Precision shut-off pins provide gate control. Valve actuators are synchronized with millisecond accuracy throughout all gates to deliver a balanced melt flow. The M05VG nozzle is for commodity materials as well as engineered and high-temperature polymers.
