What injection molder wouldn’t like to balance a multi-cavity mold more quickly and precisely without having to take the mold out of the press? And who wouldn’t want to be able to change a cavity filling pattern without having to move or add gates or modify the part design?
These are not wishful daydreams anymore. Using a new melt-management concept introduced at the NPE show 2006, BTI is developing technologies that provide these previously unknown abilities. The solution is trade named iMARC™, for In-Mold Adjustable Rheological Control, and these new systems are based on BTI’s MeltFlipper and MAX melt-management technologies.

Optimizing Filling Patterns
The iMARC systems allow the user to take advantage of the viscosity changes that occur naturally as the materials flows through the melt delivery system. This dynamic rheological control was non-existent with traditional molding...until now.
iMARC systems provide users with a new virtual button on the machine’s process controller. A molder now can have dynamic control over the melt, which allows the balance and cavity filling pattern to be optimized for a specific part quality goal...independent of whether it is a single cavity or a multi-cavity mold. And all of this can be achieved without changing gate location, part geometry, or process...or without ever taking the mold out of the press.

Dynamic Mold Balancing
BTI’s new iMARC systems are not yet ready for production purposes. BTI continues to perform R&D to optimize the designs before releasing them to the industry. Please check back often and stay tuned for production release dates and information.
