Multi-Tip Valve Gate
The Rheo-Pro® M05VG multi-tip valve gate is ideal for molding direct gated micro parts with crisp, clean gate marks. The M05VG distributes melt through tight, circular clusters of 6 gates per nozzle. An X-shaped hot runner manifold system with 4 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.
Improve Part Quality
The M05VG can direct valve gate micro parts with a weight of less than 5 mg. It delivers crisp, clean gate marks of 0.7 mm - 1.0 mm diameter with zero gate vestige. Traditional thermal gates and hot tip gates experience inherent problems with micro parts because of cold slugs and gate vestige on the surface. These methods often fail to achieve the part quality required for precision micro parts, particularly in medical applications.

Increase Productivity
Automation and valve gating go hand in hand. Multi-tip valve gating elevates high volume production of micro parts to the next level of consistency, quality and efficiency. Precision shut off pins guarantee the ultimate gate control. The valve actuators are synchronized with millisecond accuracy throughout all gates to deliver a completely balanced melt flow. The M05VG nozzle is especially suited for commodity materials but performs well with engineering and high temperature polymers.
