Packaging
MHS delivers a wide range of plastic injection molding solutions for high volume packaging, from thin wall containers and closures to PET bottle preform molds. We help you produce safe, strong and environmentally friendly plastic parts that take care of the product, our planet and your bottom line. Discover why companies around the world rely on Rheo-Pro® hot runner systems.
Thin Wall Parts
For packaging containers thin wall means wall thicknesses that are less than 0.025 inch (0.62mm) with a flow length to wall thickness ratio greater than 200. MHS offers specialized solutions for thin wall packaging applications including extremely compact stack molds with back-to-back Rheo-Pro® iVG™ internal valve gate technology.
Substantial Savings
New iVG™ stack mold technology allows plastic closure manufacturers to double production of valve gated parts without having to run additional or larger injection molding machines. This leap technology exploits the untapped potential of smaller, more efficient machines by adding a second parting line to the closure mold. The patented internal valve gate design of the new Rheo-Pro® iVG™ hot runner system now allows mold makers to build back-to-back "short stacks", compact enough to fit into smaller 180-300 ton machines.
Ultra Compact
In order to lower the production cost of injection molded caps and closures, molders must increase productivity. Without investing in additional equipment, greater production output can only be achieved by reducing cycle times. However, it is impossible to cut cycle times in half on a single face mold, given the high degree of efficiency already in place. Doubling the number of parts produced by implementing a stack mold solution now makes it possible.
What makes Rheo-Pro® iVG™ hot runner systems so unique is that they don't require larger injection molding machines because of their extremely compact size. They are also maintenance free by doing away with wear items such as seals and lubricants. Molds can run millions of cycles and parts continuously, without interruption.
