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.
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.
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?
By experimenting with the photovoltaic reaction in solar cells, researchers at MIT have made a breakthrough in energy efficiency that significantly pushes the boundaries of current commercial cells on the market.
In a world that's going green, industrial operations have a problem: Their processes involve materials that are potentially toxic, flammable, corrosive, or reactive. If improperly managed, this can precipitate dangerous health and environmental consequences.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
