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.
A postcard or post card is a rectangular piece of thick paper or thin cardboard intended for writing and mailing without an envelope. There are novelty exceptions, such as wood postcards, made of thin wood, and copper postcards sold in the Copper Country of the U.S. state of Michigan, and coconut "postcards" from tropical islands.
In some places, it is possible to send them for a lower fee than for a letter. Stamp collectors distinguish between postcards (which require a stamp) and postal cards (which have the postage pre-printed on them). While a postcard is usually printed by a private company, individual or organization, a postal card is issued by the relevant postal authority.
