Book Description :

Extrusion is by far the most important and the oldest processing and shaping method for thermoplastic polymers. This process concerns almost all synthetic polymers, as well as elastomers or food materials. Single-screw extrusion is mainly used nowadays to manufacture finished goods or semi-finished products. More than 90 million tons of thermoplastics are therefore processed every year. Twin-screw extrusion may be divided into two systems: contra-rotating systems used within the context of PVC extrusion, for the manufacture of pipes or profiles; and co-rotating systems experiencing nowadays a very significant development, because of their significant adaptability and flexibility, which enables the manufacture of specific materials (polymer alloys, thermoplastic elastomers, filled polymers, nanocomposites). Extrusion is carried out by passing molten polymer through a tool called die that will give the product its final shape (films and sheets, rolled products, and electric cables). Thanks to the design of dies, we obtain at the output a product with controlled dimensions, uniform speeds and homogeneous temperatures. The book will discuss the same production types, but only in the case of coextrusion flows, i.e. multilayer stratified products. First of all, we will present in this book the physics of the mechanisms at stake, then propose more or less complex models in order to describe these mechanisms and then go forward in the interpretation of results and the control of condition flows.

Book Description :

A revised version of this book is now available. The polyethylene industry has been in the midst of major restructuring and rationalization. This has lead to joint ventures and alliances to combine technologies and exploit opportunities to maximize improvements in process productivity, catalyst innovations, and enhancements in extrusion technology and converting. This comprehensive study of the polyethylene film extrusion process describes this technology in detail. In depth descriptions of the manufacturing processes for polyethylene homopolymers and copolymers, including metallocenes, are reviewed. All aspects of machine design with particular emphasis on screws and dies including coextrusion are discussed comprehensively. With computer modeling, the interactions between equipment and polymer are quantified. All aspects of equipment design and polymer features that control melt fracture, interfacial instabilities, gauge control, output and temperature, and cooling of blown and cast film processes are presented quantitatively. This methodology will highlight solutions in troubleshooting for optimum design and operation and the best available polymer and formulation choices. All polyethylene film applications in packaging, agriculture, lamination, and construction, consumer, industrial, and health care are reviewed and discussed in depth.

Book Description :

Plastics extrusion is a high volume manufacturing process in which raw plastic material is melted and formed into a continuous profile. Extrusion produces items such as pipe/tubing, weather stripping, fence, deck railing, window frames, adhesive tape and wire insulation. There are fundamentally two different methods of extruding film, namely, below extrusion and slit die extrusion. The design and operation of the extruder up to the die is the same for both methods. The moulding process is one of the most important plastic processing operations. It is an important commercial process whereby a resinous polymeric compound is converted into useful finished articles. The origin of this process is dates back about a century to the invention of a plunger type machine. The mould has its own importance, which give the required shapes of the products. The vast growth of injection moulding is reflected dramatically in many types and sizes of equipment available today. Plastic moulding especially thermoplastic items may be produced by compression moulding methods, but since they are soft at the temperature involved, it is necessary to cool down the mould before they may be ejected. Injection moulding differs from compression moulding is that the plastic material is rendered fluid in a separate chamber or barrel, outside the mould is then forced into the mould cavity by external pressure. Plastic technology is one of the most vigorous manufacturing branches, characterised by new raw materials, changing requirements, and continuous development in processing methods. The injection moulding machines manufacturers plays an important part in the creation of injection moulding technology, process control, to essential mechanical engineering. Even though design is a specialized phase in engineering field, in tool and mould engineering it is totally divided into two wings as product design and tool and die design. This book basically deals with transport phenomena in polymer films, reinforcements for thermosets, miscellaneous thermoset processes, injection molding, blow molding, extrusion, basic principles of injection moulding, correct injection speed is necessary for filling the mould, plastic melt should not suffer degradation, the mould must be controlled for better quality product, logical consideration of moulding profile and material is important than standard setting guide lines, economical setting of the machine, proper maintenance of machine;, safety operations., preliminary checking for moulding, material, component, mould, machine, injection moulding technique, the various type of injection moulding machines, specifications, platen mounting of moulds, locating spigots, mould clamping, etc. The book covers manufacturing processes of extruded and moulded products with the various mould designs. This is very useful book for new entrepreneurs, technocrats, researchers, libraries etc.
