An Ohio company that offers document services is entering the in-mold labeling market with what might be a major technology play. Competitive in-mold offerings generally use identical materials such as polycarbonate label with a polycarbonate part or a polystyrene label with polystyrene part. Compatible melt indexes are critical, creating complications when a plastic is highly filled. “A lot of work goes into matching the like label with a part to insure it bonds well and looks good,” says David Coughlin, director of operations of Industramark, which is being introduced at the National Plastics Exposition this week in Chicago. “This truly is a challenge and a good part of the reason why in-mold labels have not taken off outside of prime labeling applications that are typically only polypropylene.” Working with Fusion Graphics, also of Dayton, OH, Industramark has developed a 7 mil micro porous film. “We do not depend on like chemistries for bonding but rather the plastic (any thermoplastic) being molded flows into the micro bonds and makes a permanent bond to the label. Based on our relationship with Fusion Graphics and their patent position, we have a novel solution that makes other in-mold products obsolete and very complex.”
Labels are not new to Industramark’s parent, Standard Register. They accounted for 13 percent of revenues last year. In response to a question from Design News, Industramark did not provide information on the material used for its in mold labels. A patent awarded to Robert Freund of Waynesville, OH in 2007 describes a new IML technique based on a precipitated silica-filled microporous sheet material. If properly coated, the material is well suited to the IML task, according to the patent. The novel system also requires special inks. The technique is said to not only to improve quality of graphic images, but also to cost less. A wide range of materials, including thermosets, can be used.
A composite based on a high-performance PEEK-like resin we told you about two years ago when it was still in R&D has now been licensed by the US Naval Research Laboratory (NRL) for commercial manufacturing.
Microsoft, HP, Dassault, and other industry heavyweights in 3D printing have launched a new 3DP file format, 3MF. The consortium says the spec will more fully describe a 3D model and will be interoperable with multiple applications, platforms, services, and printers.
NASA's been working on several different ongoing projects for 3D-printed rocket engine components in metals and now it's reached another first in aerospace 3D printing: a full-scale, 3D-printed rocket engine component made of copper.
