The Beaumont Technologies, Inc. (Erie, PA) iMARC ™ in-mold adjustable rheological control system was designed to enable processors to better control and take advantage of rheological changes—all without ever having to take the mold out of the press. This latest advancement in melt-management, which is based around the firm’s popular MeltFlipper ® and MAX ™technologies, is a major step forward for the injection molding industry. The rheological control system is available in a variety of standard insert sizes and melt-management designs. Custom designs also will be offered for unique applications. The basic premise of iMARC single axis or multi-axis molding technologies is to allow processors not only to dynamically optimize mold balance from cavity to cavity, but also dynamically change and control the actual filling pattern within a given cavity, without changing gate locations, part geometries, process conditions, or having to take the mold out of the press. Much like standard MeltFlipper technology, these latest advancements are applicable in all cavity ranges and all molding materials—including single cavity molds and LCP materials. This technology provides an unprecedented level of control within the mold and cavities to provide a universal mold balance, reduce scrap rates, reduce mold startup and qualification times, provide a much wider process window, create stronger weld lines (to eliminate part breakage issues) or move weld lines to non-cosmetic areas, eliminate filling problems in areas such as thin wall sections, eliminate short shot issues and gas trap locations, and solve cosmetic problems, including “glass-migration” by manipulating the arrangement of glass fibers in the polymer.
