This paper proposes an innovative factory planning methodology to achieve the objectives that were defined by Flexitallic for the future expansion of the Thermiculite production line. The concepts under investigation extend to the analysis of flow benefits and restrictions considering product features and demands addressed in a proposed Batch/Flow Comparative Matrix. Furthermore, this paper introduces the Quality Function Deployment (QFD) concept to support the manufacturing line design using a mechanism of incorporating commercial awareness in all stages of the product deployment. The original QFD ensures process planning by bringing parts deployment into parts characteristics through the House of Quality. This study renews the original QFD by developing the Strategic Alignment of Quality Function Deployment (SAQFD) to achieve proactive management of Houses III and House IV. The case study demonstrates the utilization and applicability of the proposed methodologies, and demonstrates their importance during the design of a high volume production line.

AbstractChlorinated Paraffins (CPs) are high volume production chemicals and have been found in various organisms including humans and in environmental samples from remote regions. It is thus of great importance to understand the physical–chemical properties of CPs. In this study, gas chromatographic (GC) retention indexes (RIs) of 25 CP congeners were measured on various polar and nonpolar columns to investigate the relationships between the molecular structure and the partition properties. Retention measurements show that analytical standards of individual CPs often contain several stereoisomers. RI values show that chlorination pattern have a large influence on the polarity of CPs. Single Cl substitutions (–CHCl–, –CH2Cl) generally increase polarity of CPs. However, many consecutive –CHCl– units (e.g., 1,2,3,4,5,6-C11Cl6) increase polarity less than expected from the total number of –CHCl– units. Polyparameter linear free energy relationship descriptors show that polarity difference between CP congeners can be explained by the H-bond donating properties of CPs. RI values of CP congeners were predicted using the quantum chemically based prediction tool COSMOthermX. Predicted RI values correlate well with the experimental data (R2, 0.975–0.995), indicating that COSMOthermX can be used to accurately predict the retention of CP congeners on GC columns.

ABSTRACTA high-volume epitaxial reactor has been used to investigate the feasibility for the production growth of GaAs on silicon substrates. The reactor is a customized system which has a maximum capacity of 39 three-inch diameter wafers and can accommodate substrates as large as eight inches in diameter. The MOCVD material growth technique was used to grow GaAs directly on p-type, (100) silicon substrates, three and five inches in diameter. The GaAs surfaces were textured with antiphase boundaries. Double-cyrstal rocking curve measurements showed single-cyrstal GaAs with an average FWHMof 520 arc seconds measured at four points over the wafer surface. Within-wafer thickness uniformity was ± 4% with a wafer-to-wafer uniformity of ± 2%. Photoluminescence spectra showed Tour peaks at 1.500, 1.483, 1.464, and 1.440 ev. Schottky diodes were fabricated on the GaAs on silicon material.

Chopped carbon fiber tape-reinforced thermoplastic material is specifically developed for the high-volume production of lightweight automobiles. With excellent design processability and flexibility, the carbon fiber tape-reinforced thermoplastic material is manufactured by compressing large amounts of randomly oriented, pre-impregnated unidirectional tapes in a plane. Therefore, the carbon fiber tape-reinforced thermoplastic material presents transversely isotropic properties. Transverse shear effect along the thickness direction of carbon fiber tape-reinforced thermoplastic beam has a distinct influence on its flexural deformation. Accordingly, the Timoshenko beam theory combined with vibration frequencies was proposed to determine the set of transverse flexural and shear moduli. Meanwhile, the transverse flexural and shear moduli of carbon fiber tape-reinforced thermoplastic beam were finally determined by fitting all the first seven measured and calculated eigenfrequencies with the least squares criterion. In addition, the suggested thickness to length ratio for the 3-point bending test and Euler–Bernoulli model was given.

Several designs of a manufacturing line for the production of extruded foods were developed and compared with the current production line design. The manufacturing line consisted of six unit operations: batching, grinding, extruding, drying, further processing, and packing. The authors performed the comparisons by simulating the current design and the proposed alternatives. The alternatives consisted of modifications to the extruder-dryer and/or packing line designs. The simulation results indicated that all the alternate designs roughly doubled system throughput compared to current designs but did not differ significantly in performance among themselves. The doubled output is worth about $2.5 million per year. This is easily enough to justify the cost of new equipment. One design would cost less to implement than the others and thus was the preferred option.
