MHS to Feature new iVG™ 4 Hot Runners at K 2025

The updated design of the internal valve gate nozzles offers space-efficient, high- performance molding

 

 

[Milton, Ontario] – MHS Mold Hotrunner Solutions Inc., a global leader in hot runner technology, proudly presents the innovative Rheo-Pro® iVG™ 4 hot runner program, designed to revolutionize injection molding efficiency. With a patented internal valve gate design, new fourth generation iVG™ nozzles allow manufacturers to build extremely compact molds, while maximizing production capacity and profitability. New iVG™ series nozzles will be on display at K2025 in Germany from October 8-15 (Hall 1, Booth C40).

 

Space inside the mold is a valuable commodity, and Rheo-Pro® iVG™ technology offers a groundbreaking solution by enabling ultra-compact single face molds, back-to-back “short stacks,” and stack molds with an impressive tip-to-tip length of just 285mm and a pitch distance of 63.5mm. This space-efficient design provides tool makers and OEMs with exciting new opportunities to optimize mold layouts for applications such as single face molds, stack molds, rotating cube molds, and multi-material injection molds.

 

For injection molders, the benefits are substantial. The compact iVG™ hot runner system allows for stack molds that increase production output on smaller machines with lower clamp tonnage, resulting in reduced operating costs and improved energy efficiency. By producing more plastic parts per cycle in a smaller footprint, manufacturers can achieve significant cost savings while maintaining the highest levels of quality and precision.

 

The new Rheo-Pro® iVG™ 4 is the world’s most compact internal valve gate nozzle. It is the only pneumatic valve gate hot runner that operates entirely without elastomeric seals, lubricants, or cylinder cooling. Unlike electric actuators, the iVG™ can operate at extreme temperatures of up to 400°C (750°F). The new nozzle series features an upgraded design, including a smaller valve pin diameter and more powerful internal actuation with a force of 140 psi (10 bar) air pressure, producing 90 lbs (400N) of valve pin closing force at the gate. This allows the iVG™ to process parts and materials that require a higher packing or hold pressure and time, typically required for thick-wall precision parts with semi-crystalline materials.

 

The new 2.5 mm diameter valve pins increase the flow channel and reduce melt pressure drop and melt shear. More valve pin closing force (by a factor of x2.5) increases the hold pressure up to 11,850 psi (817 bar), allowing for a higher melt density in the mold cavity for added part precision and less shrinkage.

 

New precision valve pin tip-guidance increases the lifetime of the gate and ensures perfect gate marks on the part surface.

 

The iVG™ 4’s patented design completely rewrites the rules of valve gating technology and creates endless new possibilities, from high-cavitation to single-drop hot runner systems.

 

MHS remains committed to delivering cutting-edge solutions that empower manufacturers to stay competitive in today’s demanding production environment. Discover how Rheo-Pro® iVG™ 4 hot runner systems can elevate your injection molding operations.

 

Craig Sandey GM of MHS says,

“We launched the iVG series over 15 years ago. There is nothing like it on the market that can compete in terms of pure reliability and design flexibility.”
