Micro-injection moulding is a new process, and as such it has not been thoroughly investigated until now. The peculiarities related to the three dimensional aspect of the cavity and the very small length and time scales at stake make it a very specific technology compared to conventional injection moulding. The aim of this thesis is to pave the way for micro-injection moulding modelling with a special emphasis on micro-cavity filling. Besides giving insight into the process, this work demonstrates the importance of visco-elastic effects and investigates further related issues. The different steps adopted in this work are the following ones: first an extensive review of the process is proposed, followed by a reflection on micro-cavity filling and polymer behaviour which ends up with the choice of the Giesekus model as an appropriate viscoelastic model for some polymers used in this process. A chapter dedicated to polymer characterization conducted on PC Lexan HF11110R, a micro-injection suited amorphous material, shows that the Newtonian viscosity is very low. In this case, the model admissibility from a mathematical and thermodynamic point of view is not guaranteed. This admissibility is the object of a chapter which provides an analysis for the Giesekus model completed with the PC Lexan material parameters. A further mathematical consequence of a vanishing Newtonian viscosity is that the number of inlet boundary conditions to be prescribed for the extra-stress tensor is reduced to 4 instead of 6 in case of a non-vanishing Newtonian viscosity. A specific numerical scheme to tackle this problem is proposed along with a theta-splitting based method which allows us to separate the viscous and visco-elastic effects in the governing equations and to treat subsequently a modified Stokes sub-problem and a transport sub-problem. Finally, a micromixer design and prototyping is presented as an application of this promising process.

"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

The project is to develop a mini micro injection moulding machine. This study consists of three stages which are design concept, fabrication process, and assembly process of the mini micro injection molding that will capable to run similarly as the real industries conventional micro injection molding machine. For the design concepts, two to three injection molding mechanism is designed, compared and choose the best design that can match the requirement of the mini micro injection machine. After the design has been decided, fabrication process will take place. In this project, it is important to define and organize the best and fastest method that suitable to fabricate the machine. Assembly processes need to be done to complete the machine. It consist of assemble the two unit of injection machine which are injection unit and clamping unit. For the last stage, in order to test and function the machine, we need to make it capable to melt the resin plastic and the injection plunger can inject the molten plastic in to the mould cavity through the nozzle.

Use of polymers is widespread in the electronics industry, both in manufacturing integrated circuits and as components in the completed devices. In addition to providing an update in conventional microlithography technology, Micro- and Nanopatterning Polymers describes new patterning techniques involving block copolymers, direct deposition of metal oxides and other materials, and image-wise chemical deposition. It illustrates the challenges and opportunities in designing ArF excimer laser resists in the next generation of lithographic technology. The book includes discussions of material design alternatives, acid generator chemistries, and acid diffusion mechanisms in chemically amplified resists, which have now replaced novolac/diazoquinone resists in device manufacturing. Providing insight into the most recent breakthroughs in nano-technology, this unique book is an important step in the development of integrated circuits.
