Seems like a really promising technology and one that could have significant ramifications for manufacturers given the widespread use of injection molding in production. Is this a technology experiment or is DuPont further along in terms of trials or early use case testing, or perhaps even gearing up to commercialize the technology?
Like most innovations, the total cost of adoption is based on the predicted savings and the cost to upgrade. 30% time savings is really attractive in a high-volume process, but that will be balanced by the cost to modify or replace the existing tools. I'm going to guess that DuPont has done their homework and charted a path that includes the cost of tool upgrades. Otherwise this innovation will take a large time to permeate production floors as they replace older equipment or build new lines.
I am a little confused on how this technology is used especially in regards to the moving side mold cylinder. Where does the dosed melt cushion come from on the moving side of the mold. I can sort of understand adding material through the hot runner, but this is still hard to grasp. In most injection molding applications, all of the fill, pack, and hold pressures are applied by the injection screw. The length of time for pack and hold are determined by the gate freeze off time. Some better description of what this technology does would help in applying it.

In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
