Progress in Polyester Development for EBM Applications

The optimal formulation for a clear extrusion-blow-molding (EBM) material must fulfill three main requirements: it must process efficiently on existing equipment, produce bottles with robust drop-impact performance, and have an acceptable recyclability story.

Analysis of Fluid-Assisted Injection Techniques by Use of Ultrasonic Measurements

Gas-assisted injection molding (GAIM) and water-assisted injection molding (WAIM) are well-established processes for producing parts with (functional) hollow space. The quality of these parts greatly depends on internal part properties, such as residual wall thickness.

Innovations in Film Processing

To produce quality film economically requires that all the parts of the processing line work together seamlessly to deliver precise film thicknesses at fast speeds without wasting material. As more specialized—and more expensive—additives enter the market, it is even more important not to waste raw materials.

Control Technology: Hot Panels

High-quality plastic panels can be formed from foil material by means of vacuum deep-drawing with two sheets. However, accurate matching of the process technology – and particularly the temperature control – remains a challenge.

Forums Highlight News in Energy, Healthcare, and Green Technologies

The Fundamentals & Fellows Forum and three New Technology Forums, held at the SPE’s ANTEC 2012 Conference April 2-4 in the Orange County Convention Center in Orlando, Fla., present emerging research, some close to commercial, some still in the concept stage. This year’s four forums (www.4spe.org/antecnpe-2012-new-technology-forums) cover fundamental research, energy and renewable energy, healthcare, and green technologies. Unlike other ANTEC papers, however, these aren’t reprinted later. You have to be there. That’s easier this year because ANTEC is co-located with the National Plastics Exposition April 1-5. Here’s a preview of some of what you’ll hear.

Presenters at the Fundamentals & Fellows Forum, Monday a.m. April 2, are fellows of the Society of Plastics Engineers, a small group of individuals chosen for major contributions to the fundamental knowledge of plastics, or other renowned experts in their fields. Costas Gogos, distinguished research professor of chemical engineering and Huiju Liu, post doctoral fellow at the New Jersey Institute of Technology (www.njit.edu) and the Polymer Processing Institute, Newark, N.J. (www.polymers-ppi.com), present a new pharmaceutical extrusion technology in which poorly water-soluble drugs are melt compounded into a water soluble polymeric formulation, absorbable by the human body.

Additives Annual 2011

Process- and product-enhancing additives are helping the industry bounce back from recession.

By Michael Tolinski

Noticeable in 2011 was the development of a number of productivity-enhancing and market-expanding additives for molders and converters recovering from the Great Recession. Suppliers have been releasing new processing aids that increase the quantity of parts or product produced per shift, with the potential for lowering total costs per part. Meanwhile, other new additives have been developed that toughen or color plastics in unique, application-specific ways. As described in the examples below, such continuing activity indicates that the technological nexus of compounders, processors, and additives suppliers remains strong in the industry.
