The analysis was performed using Bulk Flow Analyst™ from Overland Conveyor Company. In the slush molding process, plastic resin is rolled about inside a volume consisting of a powder box and a tool. The tool is heated, so as the particles come into contact with it, they melt and become stuck to the tool. Using this process, users can find out what rocking and rolling sequence gives adequate coverage to the finer details of the tool. www.applieddem.com www.overlandconveyor.com

Best opportunities are anticipated in packaging uses such as caps and closures, and housewares and personal care products. Demand for injection molded high density polyethylene will be fueled by industrial packaging opportunities such as shipping pails, and totes and crates.

Injection molded polystyrene demand will increase slowly due to competitive pressures from lower cost resins such as polypropylene and high density polyethylene. Nevertheless, polystyrene remains one of the best materials for injection molding, with good growth anticipated in electrical and electronic components, and consumer products. Best growth is expected for injection molded thermoplastic polyester and polycarbonate.

Measurements and analyses of the energy used in primary processes, ancillary services, and the building envelope were included in the assessments. Using the resulting data, IAC staff were able to identify opportunities for energy savings, waste-reduction measures, and productivity improvements for each plant. IAC faculty and students captured these opportunities in a set of recommendations made to the individual companies. A broad sampling of the recommendations is included in 11 case studies that are intended to help other companies identify similar opportunities for savings in their own manufacturing operations.

Packaging and consumer markets together accounted for 64 percent of total injection molded plastic demand in 2005. Packaging markets will be driven by opportunities in caps and closures, as well as industrial shipping pails, and totes and crates. Consumer market growth will reflect needs for inexpensive, convenient, lightweight and unbreakable housewares and personal care products such as storage containers and razors.
