摘要:

AbstractProductivity gains from a CAD/CAM system through integration with other factory automation systems have shown tremendous benefits for the plastics industry. For successful utilization of CAD/CAM systems, companies have to maximize the use of electronic data base and communication with other systems. General Electric, through its Calma operation, is aggressively addressing these integration opportunities in the plastics industry. The importance of the Computer Integrated Manufacturing system along with design and engineering tools available for increased productivity, are described in this paper.

摘要:

AbstractThis paper addresses experimental techniques for evaluating distributive laminar mixing in continuous flows. Analysis of mixing performance for arbitrary mixers and fluids is too complex to be solved from first principles for all but the simplest systems. Procedures for the acquisition and interpretation of mixing data from modelled mixers under laboratory analysis are reviewed, and guidelines for future mixing experimentation are presented.

摘要:

AbstractWith the increasing demands for quality in plastic products, the characterization of materials becomes more and more important in the evaluation of properties of structural parts and processing conditions, and in performing quality control.An attempt shall be made to introduce basic principles for the sizing and manufacture of molded parts by means of the fewest possible material data. This characterization is to be made using the p‐v‐T diagram, the shear modulus curve, and the viscosity curve. These material data are then used for quality control of the raw material and the finished prod

摘要:

AbstractModern, trend‐setting small injection molding machines should be designed so that they open up new applications to the plastics processor through utilization of microelectronics. In the sector of control, it would be equivalent to stagnation if only the familiar functions were realized with modern control circuits of a higher integration level and if the possibilities of these modules were not utilized to simplify operation, to expand the technological possibilities, and to illustrate the sequences of processes. The mechanical and hydraulic designs should be adjusted to these requirements.The design and extent of the electronic control system should be such as to ensure an economically reasonable relation between extra price and additional benefit—a basic requirement for offering standard suppl

摘要:

AbstractThe mathematical treatment of single‐screw devolatilizing extruders has been based up until now on the Newtonian law of flow. Only very recently have mathematical models been developed that take into account the intrinsically viscous behavior of plastic melts. Here, however, solutions are possible only by using numerical procedures.In this paper, a different approach is taken. On the basis of known numerical solutions and experimental investigations, approximation equations are presented that enable devolatilizing extruders to be designed by relatively simple means. There is good agreement between the numerical and experimental result
