  • In today’s practical and cost-conscious world, sheet-metal parts have already replaced many expensive cast, forged, and machined products. The reason is obviously the relative cheapness of stamped, or otherwise mass-produced parts, as well as greater control of their technical and aesthetic parameters. That the world slowly turned away from heavy, ornate, and complicated shapes, and replaced them with functional, simple, and logical forms only enhanced this tendency. Remember old bathtubs? They used to be cast and had ornamental legs.

  • In the following calculation procedures, the design of steel members is executed in accordance with the Specification for the Design, Fabrication and Erection of Structural Steel for Buildings of the American Institute of Steel Construction. This specification is presented in the AISC Manual of Steel Construction. Most allowable stresses are functions of the yield-point stress, denoted as Fy in the Manual. The appendix of the Specification presents the allowable stresses associated with each grade of structural steel together with tables intended to expedite the design.

  • Recycling of plastic materials is now an important field in the plastics industry, not just an activity born under environmental pressure. The recycling processes include industrial operations in which secondary materials are reprocessed and/or monomers recovered for further polymerization; such processes are termed secondary and tertiary recycling.

  • The constitutive law of plastic deformation expresses the effects of material behavior and properties for stress analysis in the design of manufacturing technology and product service behavior, for materials testing, and for the maintenance of structural and machine components. The book represents the state of the art, but the editors do not rule out other concepts of constitutive laws. There are many different facets of the same problem and as many answers; the right one is the one that gives the most practical solution, the one that best serves the specific problem....

  • Design Guides for Plastics covers each topic in a single page to provide a basic reference to each topic. This space constraint means that each topic is only covered to a basic level. Detailed plastic product design will  always require detailed knowledge of the application, the processing method and the selected plastic.

  • Most plastic materials are used because they have desirable mechanical properties at an economical cost. For this reason, the mechanical properties may be considered the most important of all the physical and chemical properties of high polymers for most applications. Thus everyone working with such materials needs at least an elementary knowledge of their mechanical behavior and how this behavior can be modified by the numerous structural factors that can be varied in polymers.

  • The mold is probably the most important element of a molding machine. It is a arrangement, in one assembly, of one (or a number of) hollow cavity spaces built to the shape of the desired product, with the purpose of producing large numbers of plastic parts. Thus the primary purpose of the injection mold is to determine the final shape of the molded part (shaping function). In addition to give the final shape of the molding, the mold performs several other tasks.

  • Innovation in engineering often means the clever use of a new material - new to a particular application, but not necessarily (although sometimes) new in the sense of ‘recently developed’. Plastic paper clips and ceramic turbine-blades both represent attempts to do better with polymers and ceramics what had previously been done well with metals. And engineering disasters are frequently caused by the misuse of materials.

  • When the plastic melt fills the mold, it displaces the air. The displaced air must be removed quickly, or it may cause burn spot (due to the fast compression of trapped air pocket by the low-thermal-conductivity polymer melt), or it may restrict the flow of the melt into the mold cavity, resulting in incomplete filling (short-shot problem). Consider the injection-molding of a air bag housing. Notice that the part consists of a thin central region and a thick rim around it. A single gate is adopted in the original design. Most of the melt flow along the part side since...
