for 2006 IEEE 1 An Environmental Analysis of Injection Molding Extended Abstract – Green Manufacturing Processes Alexandre Thiriez and Timothy Gutowski Department of Mechanical Engineering Massachusetts Institute of Technology Rm. 35-234 77 Massachusetts Ave. Cambridge, MA 02139 Plastic components are integral parts in electrical and electronic (E&E) products. 8.5% of the plastic production is ...

The search for new effective structure-forming agents of natural origin in order to improve the technology fish molded products is an urgent scientific and industrial problem. In course study, obtain minced systems, frozen pollock pink salmon have been used that meet technical requirements current regulatory documentation. Mixtures cryoconcentrates from seafood, rice wheat flour, enzyme transgl...

OBJECTIVE To know the effectiveness of a custom molded fitting chair between pre- and post-chair status through comparison of musculoskeletal indices in severely disabled children. METHODS We researched 34 severely disabled patients who had used a custom molded fitting chair continuously for more than a year. There were 27 cerebral palsy patients and 7 patients with other kinds of diseases th...

Solvent cast and compression molded composite films based on poly(vinylidene fluoride-trifluoroethylene), containing pristine and silylated BaTiO 3 particles, were poled, and their electromechanical response (d 33), their dielectric properties, and the crystalline structure of the embedded BaTiO 3 particles, probed by X-ray diffraction, were recorded during one week. Their d 33 was also measure...

This paper shows injection molded millimeter-wave horn array antenna for the 1-dimensional APAA(Active Phase Array Antenna). The antenna is composed of horn antennas, grooved circular waveguide polarizers, E-plane T-junctions, and E-plane bends employing dielectric waveguides. This structure makes it possible to manufacture a feed circuit and radiating elements as an integrated unit by using in...

Silicon carbide is the most important and versatile non-oxide ceramic. Powder injection molding (PIM) is a method of high-speed fabrication of complex near-net shapes of SiC and other powders. Green micro-machining (GMM) is used to extend the shaping capability of green ceramics and powder metallurgy to smaller feature sizes. Debinding—removal of organic additives—is the rate-limiting step in P...

An injection molding process for the fabrication of disposable plastic microfluidic chips with a cycle time of 2 min has been designed, developed, and implemented. Of the sixteen commercially available grades of cyclo-olefin copolymer (COC) that were screened for autofluorescence and transparency to ultraviolet (UV) light, Topas 8007 x 10 was identified as the most suitable for production. A ro...

the main objective of this study is identification and validation of symptoms and dimensions of organizational mindfulness in higher education. this study is a mixed research, of explanatory sequential design, and in the area of applied research. research population of qualitative part includes scholars and academics of faculties of management from public universities located in tehran from whi...

The ease with which modern plastics can be injection molded makes them very suitable for the production of many different products and, today, are often used as substitutes metal. Polypropylene (PP) is one most widely thermoplastics globally since it useful, cost-effective and flexible molding. However, amount harm to environment caused by plastic waste has become phenomenal recycling a serious...

The aim of this study was to design a tooling system for manufacturing automotive components using natural fiber polymer composite (NFPC) material. As case study, an battery cover selected and compression molding tool designed, keeping in mind the need simplicity ensuring low cost process. However, since original part injection-molded with virgin polypropene, some vital changes made process wer...
