Book Description
One of the key aspects of the production of high precision components is the need to meet extremely tight dimensional tolerances, typically in the submicron range, and maintain these tolerances over the practical lifetimes of the molded articles. In addition, as many of the precision components are utilized in various optoelectronic systems and devices, control of optical and electrical properties is often crucial. The strict control of dimensional and electro-optical properties requires a systematic reexamination of the conventional injection-molding process with special consideration of its impact on the dimensions and electro-optical characteristics of the molded article. This volume examines precision injection molding from different perspectives, covering materials, process and hardware aspects of the technology, with special emphasis on the dimensional integrity and stability of the molded components. Special topics covered in this volume include: dimensional stability of molded plastics, models for warpage development, compact disc molding, process control, crystallization phenomena in injection molding, micro-molding and microfluidics.

Book Description
"Micro Injection Molding" meets the need for a dedicated book dealing exclusively with micro injection molding and overcoming the challenges of managing and processing polymer materials at ultra-small scales. Micro injection molding is the primary process for the mass production of polymer components with critical dimensions in the sub-millimeter range; however, it is not just a simple downscaling of conventional injection molding, and specific material-process-product interactions must be understood in order to achieve near zero-defect net-shape micro molded products. Micro molding is typically associated with ultra-high accuracy and superior process capabilities. Micro molded products have dimensional tolerances down to the single-digit micrometer range and surface finish with roughness from the sub-micrometer down to a few nanometers range. Micro and nano-structured tool surfaces are reproduced with very high replication fidelity onto the polymer products. Micro injection molding is highly suitable for the manufacture of multifunctional micro components such as micro implants, microfluidic systems, polymer micro optical elements, and micro mechanical systems. This book provides engineers, project managers, researchers, consultants, and other professionals involved in precision polymer processing and micro manufacturing with a comprehensive, up-to-date, and detailed treatment of the main topics related to micro molding, from material and process technology to tooling, to key-enabling technologies, and multimaterial process variations. Contents: • Part 1 – Polymer Materials and Process Micro Technology: micro injection molding machines technology; micro molding process monitoring and control; polymer materials structure and properties in micro injection molding parts; surface replication in micro injection molding • Part 2 – Tooling Technologies for Micro Mold Making: micro machining technologies for micro injection mold making; ultra-precision machining technologies for micro injection mold making; surface treatment of mold tools in micro injection molding • Part 3 – Micro Molding Key-Enabling Technologies: vacuum-assisted micro injection molding; modeling and simulation of micro injection molding; metrological quality assurance in micro injection molding; additive manufacturing for micro tooling and micro part rapid prototyping • Part 4 – Multimaterial Micro Processing: micro powder injection molding; multimaterial micro injection molding

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. TAGS Plastics Extrusion, Plastic Extrusion Machines, Plastic Extrusion Process, Extrusion Moulding Process, Plastic Extrusion Plants, Industrial Plastic Extrusion, Plastic Extrusion Line, Plastic Moulding, Plastic Moulding Business, Products For Plastic Injection Moulding, Plastic Moulding Process, Injection Molding Process, Plastic Injection Molding Machines, Plastic Mould Design, Plastics Injection Mould Design, Injection Moulding Design Guide, Product Design for Plastic Moulding, Design for Injection Moulding, Preparation of Plasma Films, Transport Phenomena in Polymer Films, Acrylic Fabrication, Reinforcements for Thermosets, Miscellaneous Thermoplastic Process, Compression and Transfer Molding, Disciplined Process Stategy for Injection Moulding, Injection Molding, Blow Molding, Extrusion, Newly Developed Injection Moulding Technology, Injection Moulding, Plastic Injection Moulding Environment in India, Tiebarless and 2-Platen Injection Moulding Machines, Thin Walled Injection Moulding, Mold Cooling Best Bet for High Profits, Gas Injectionmoulding Technology, Mould Materials and Processing Methods, Laminate Composition, Reinforcements for Filament Winding, Fiberglass Technology, Making Glass Fibers, Glass Composition, Glass Fabric Construction and Weaves, Plastisol Molding, Injection Molding Machines, Injection Unit, Mold Clamping Unit, Functions of Mold Components, Injection Moulding Technique, Economical Production of Parts, Thermosetting Materials and Elastomers, Tiebarless Machine, Two-Shot Moulding Process, Assisted Injection Moulding Process, Hand Injection Moulds, Single Cavity Two Plate Moulds, Multi Cavity Moulds, Three Plate Moulds, Multi Colour Moulds, Making of Glass Fiber, Glass Fiber Manufacture, Glass Fiber Manufacturing Process, Glass Fiber Manufacturing, Making Glass Fibers, Method for Making Fiber Glass, Npcs, Niir, Process Technology Books, Business Consultancy, Business Consultant, Project Identification and Selection, Preparation of Project Profiles, Startup, Business Guidance, Business Guidance to Clients, Startup Project, Startup Ideas, Project for Startups, Startup Project Plan, Business Start-Up, Business Plan for Startup Business, Great Opportunity for Startup, Small Start-Up Business Project, Best Small and Cottage Scale Industries, Startup India, Stand Up India, Small Scale Industries, New Small Scale Ideas for Plastic Extrusion, Plastic Moulding Business Ideas You Can Start on Your Own, Small Scale Plastic Extrusion, Guide to Starting and Operating Small Business, Business Ideas for Plastic Moulding, How to Start Plastic Extrusion Business, Start Your Own Glass Fiber Manufacturing Business, Plastic Extrusion Business Plan, Business Plan for Glass Fiber Manufacturing, Small Scale Industries in India, Plastic Moulding Based Small Business Ideas in India, Small Scale Industry You Can Start on Your Own, Business Plan for Small Scale Industries, Set Up Glass Fiber Manufacturing, Profitable Small Scale Manufacturing, How to Start Small Business in India, Free Manufacturing Business Plans, Small and Medium Scale Manufacturing, Profitable Small Business Industries Ideas, Business Ideas for Startup
