Abstract:
As a new plastic process technique, Gas-assisted injection molding has many advantages comparing to the traditional injection molding. Meanwhile, Optimization of Gas-assisted injection molding is more complex since many additional parameters have been introduced to the process. In this paper, a hybrid optimization approach based on metamodeling and particle swarm optimization algorithm is proposed and applied for Gas-assisted injection molding. Moreover, the validation of the approach will be illustrated through the optimization process of a real panel.

Abstract:
Innovative lightweight structures realized by employing assembly injection molding bears high potential. Using assembly injection molding, complex shaped hybrid structures can be manufactured in a precise and fast processing step. Though, especially the interface quality of a hybrid joint is a crucial factor, which determines the overall quality of such lightweight structures. High bonding strength values were achieved between aluminum and multiple polymeric materials with double-lap joints manufactured by employing assembly injection molding. Thereby, the influence of aluminum surface pre-treatments as well as intrinsic adhesion modifications of the polymeric materials were investigated.

Abstract:
In-situ thermoforming and overmolding of continuous fiber-reinforced thermoplastic composites by hybrid injection molding enables the mass production of thermoplastic lightweight structures with a complex geometry. In this study, the anisotropic mechanical behavior of such hybrid injection molded short and continuous fiber-reinforced thermoplastics and the numerical simulation of the resulting mechanical properties under flexural loading were investigated. For this, the influence of the volume flow rate between 25 and 100 cm3/s during injection molding of a PP/GF30 short fiber-reinforced overmolding material was studied and showed a strong effect on the fiber orientation but not on the fiber length, as investigated by computer tomography and fiber length analysis. Thus, the resulting anisotropies of the stiffness and strength as well as the strain hardening investigated by tensile testing were considered when the mechanical behavior of a hybrid test structure of short and continuous fiber-reinforced thermoplastic composites was predicted by numerical simulations. For this, a PP/GF60 and PP/GF30 hybrid injection molded test structure was investigated by a numerical workflow with implemented injection molding simulation data. In result, the prediction of the mechanical behavior of the hybrid test structure under flexural loading by numerical simulation was significantly improved, leading to a reduction of the deviation of the numerically predicted and experimentally measured flexural strength from 21% to 9% in comparison to the isotropic material model without the implementation of the injection molding data.

Abstract:
A method of combining Gaussian Process (GP) Surrogate model and Gaussian genetic algorithm is discussed to optimize the injection molding process. GP surrogate model is constructed to map the complex non-linear relationship between process conditions and quality indexes of the injection molding parts. While the surrogate model is established, a Gaussian genetic algorithm (GGA) combined with Gaussian mutation and hybrid genetic algorithm is employed to evaluate the model to search the global optimal solutions. The example presented shows that the GGA is more effective for the process optimization of injection molding.

A novel type of mixing-injection molding machine was used to produce tiny specimens (<1mm in size) with high trial efficiency using a small amount of feedstock (<0.05cm3 in volume). Small dumbbell specimens were produced using various feedstocks prepared by changing binder content and fraction of nano-scale Cu powder (130nm in particle size). The effects of adding the fraction of nano-scale Cu powder on the melt viscosity of the feedstock, microstructure, density and tensile strength of sintered parts were discussed.

Abstract:
Experts in injection molding often refer to previous solutions to find a mold design similar to the current mold and use previous successful molding process parameters with intuitive adjustment and modification as a start for the new molding application. This approach saves a substantial amount of time and cost in experimental based corrective actions which are required in order to reach optimum molding conditions. A Case-Based Reasoning (CBR) System can perform the same task by retrieving a similar case which is applied to the new case from the case library and uses the modification rules to adapt a solution to the new case. Therefore, a CBR System can simulate human e~pertise in injection molding process design. This research is aimed at developing an interactive Hybrid Expert System to reduce expert dependency needed on the production floor. The Hybrid Expert System (HES) is comprised of CBR, flow analysis, post-processor and trouble shooting systems. The HES can provide the first set of operating parameters in order to achieve moldability condition and producing moldings free of stress cracks and warpage. In this work C++ programming language is used to implement the expert system. The Case-Based Reasoning sub-system is constructed to derive the optimum magnitude of process parameters in the cavity. Toward this end the Flow Analysis sub-system is employed to calculate the pressure drop and temperature difference in the feed system to determine the required magnitude of parameters at the nozzle. The Post-Processor is implemented to convert the molding parameters to machine setting parameters. The parameters designed by HES are implemented using the injection molding machine. In the presence of any molding defect, a trouble shooting subsystem can determine which combination of process parameters must be changed iii during the process to deal with possible variations. Constraints in relation to the application of this HES are as follows. - flow length (L) constraint: 40 mm < L < I 00 mm, - flow thickness (Th) constraint: -flow type: - material types: I mm < Th < 4 mm, unidirectional flow, High Impact Polystyrene (HIPS) and Acrylic. In order to test the HES, experiments were conducted and satisfactory results were obtained.

Abstract:
The following paper will illustrate the development of a multiflex chain in hybrid construction. The aim of this novel chain variant is to improve the stiffness and strength in comparison to conventional plastic slide chains. A two part multiflex chain with a chain pitch of 33.5 mm and a structural width of 83 mm was used as the basis for the development of the hybrid multiflex chain. The hybrid multiflex chain is supposed to be integrated in already existing layouts of chain conveyors. The load bearing structure of the single chain links is manufactured in the metal die cast procedure while taking the constructive, production related, and operational aspects into consideration and subsequently covered in the injection molding process with plastics commonly used for multiflex chains. The evaluation of the improved stiffness and strength takes place in the course of extensive test series

Abstract:
The aim of this research was to analyze the mechanical and thermal properties of composites andhybrid composites prepared with four types of jute fibers and two different resins; biobased thermosetresins acrylated epoxidized soybean oil (AESO) and mathacrylated anhydride modified soybean oil(MMSO). The processing technique used was vacuum injection molding (VIM). Tensile and, flexuraltestings and dynamic mechanical and thermal analysis (DMTA) were used to characterize thecomposites’ properties. The results showed that the AESO composites have better tensile and flexuralproperties. This may be due to the fact that the curing conditions were quite the same for both AESOand MMSO composites but MMSO composites showed different behavior during curing step. Theywere completely cured in a shorter time compared to AESO composites. Having equal curing time forboth resins’ composites can damage the structure of MMSO composites and hybrids. Tan delta peak forthe MMSO reinforced composites occurs at higher temperatures, compared to AESO reinforcedcomposites, which means better thermal properties for MMSO reinforced composites.

Abstract:
Within healthcare there is a market pull for biomedical devices that can rapidly perform laboratory processes, such as diagnostic testing, in a hand-held format. For this reason, biomedical devices must become smaller, more sophisticated, and easier to use for a reasonable cost. However, despite the accelerating academic research on biomedical microdevices, and especially plastic-based microfluidic chips, there is still a gap between the inventions in academia and their benefit to society. To bridge this gap there is a need for new materials which both exhibit similar properties as industrial thermoplastics, and that enable rapid prototyping in academia. In this thesis, thiol-ene and thiol-ene-epoxy thermosets are evaluated both in terms of their suitability for rapid prototyping of biomedical microdevices and their potential for industrial manufacturing of “lab-on-chips”. The first part of the thesis focuses on material development of thiol-ene and thiol-ene-epoxy thermosets. Chemical and mechanical properties are studied, as well as in vitro biocompatibility with cells. The second part of the thesis focuses on microfabrication methods for both thermosets. This includes reaction injection molding, photostructuring, and surface modification. It is demonstrated how thiol-ene and thiol-ene-epoxy both provide advantageous thermo-mechanical properties and versatile surface modifications via “thiol-click chemistry”. In the end of the thesis, two applications for both polymer platforms are demonstrated. Firstly, thiol-ene is used for constructing nanoliter well arrays for liquid storage and on-demand electrochemical release. Secondly, thiol-ene-epoxy is used to enhance the biocompatibility of neural probes by tuning their flexibility. It is concluded that both thiol-ene and thiol-ene-epoxy thermosets exhibit several properties that are highly suitable for rapid prototyping as well as for scalable manufacturing of biomedical microdevices.

Abstract:
L’objectif final de ce travail est de proposer un outil numérique capable de prédire l'endommagement et la durée de vie en fatigue des matériaux et structures en composite à matrice thermoplastique. Pour ce faire, une étude expérimentale multi-échelle du matériaux PPGF40 (polypropylène chargé en fibre de verre à 40% en masse) est réalisée. Une analyse qualitative, mais aussi quantitative des différents mécanismes d’endommagement se produisant lors d’une sollicitation mécanique a été réalisée à travers des essais de flexion trois points in situ MEB, des essais de fatigue interrompus et des observations des faciès de rupture en monotone et en fatigue. A la lumière de ces essais nous avons conclu que la décohésion de l’interface fibre-matrice et la propagation des fissures à travers les interfaces apparait être le phénomène prépondérant menant à la ruine du matériau et cela indépendamment de l’orientation des fibres et du mode de sollicitation monotone ou fatigue. La démarche hybride proposée est basée sur un modèle micromécanique / phénoménologique permettant de prendre en compte l’endommagement à l’interface fibre-matrice et la plasticité de la matrice. Pour ce faire, un critère local statistique d’endommagement à l’interface fibre-matrice est introduit dans un modèle de Mori et Tanaka et la linéarisation du comportement plastique de la matrice est réalisée pas à pas, en utilisant une approche en champs moyens avec une formulation sécante. Le modèle micromécanique utilisé permet alors de prédire le comportement du matériau sous chargement monotone et notamment la première perte de rigidité en fatigue. L’analyse des résultats montre que cette dernière est directement liée à la durée de vie en fatigue du matériau. Ainsi, une méthodologie prédictive de la durée de vie est proposée et validée pour différentes configurations microstructurales. Un critère de rupture en fatigue est proposé en fonction du nombre de cycles
The main objective of this work, is to provide a numerical tool, capable of predicting the damage and fatigue life of thermoplastic matrix composites materials and structures. To do this, a multi-scale experimental study of the PPGF40 material (polypropylene loaded with 40% by mass of glass fiber) is carried out. A qualitative, but also a quantitative analysis of the various damage mechanisms occurring during mechanical loading was carried out through in-situ three-points SEM bending tests, interrupted fatigue tests and observations of fracture faces in monotonic and cyclic loading. In the light of these tests, we concluded that the decohesion of the fiber-matrix interface, and the propagation of cracks through the interfaces, appears to be, the predominant damage phenomenon leading to the fracture of the material and that, regardless of the orientation of the fibers and the loading mode. The proposed hybrid approach is based on a micromechanical / phenomenological model taking into account the damage at the fiber / matrix interface and the plasticity of the matrix. To do this, a local statistical criterion of damage at the fiber-matrix interface is introduced into a Mori and Tanaka model, and the linearization of the plastic behavior of the matrix is done step by step, using the mean field approach with a secant formulation. The micromechanical model used then, makes it possible to predict the behavior of the material under monotonic loading, and in particular the first stiffness loss during the fatigue. Analysis of the experimental results shows that the latter is directly related to the fatigue life of the material. Thus, a predictive methodology of the fatigue life is proposed and validated for various microstructural configurations. A fatigue failure criterion is proposed according to the number of cycles

This research is to develop Vibratile Injection Compression Molding (V-ICM) and integrate the Varithermo Mold Temperature (VMT) technology for increasing the Groove Filling Ratio (GFR) and reduce aspheric form errors of hybrid optical elements. PMMA and COP 480R have been used to investigate the difference in processing, and to understand the residual stress, chromatic aberration (CA) and the Modulation Transfer Function (MTF) graph for comparison. Groove filling ratio (GFR), aspheric form error and the distribution of residual stress have been studied and discussed. Results have shown that the V-ICM can enhance the GFR effectively. In addition, the fixed mold temperature and different trigger time points affect the GFR significantly under the same aspheric form errors. The GFR can achieve nearly 98.09% and aspheric form error is about 7.26μm with high mold temperature in the COP 480R processing with V-ICM and VMT technology. The results of this study can effectively enhance the accuracy of multi-scale hybrid optical elements. In the future, this technology can apply to produce the high accuracy and also have the aspheric form with different multi-scale sizes, or freeform optical elements.

This research is to develop and integrate the in-mold micro compression (IMMC) and varithermo mold temperature (VMT) method in injection molding process for investigating the multi-scale hybrid optical elements including the aspheric form error (Rt) and the replication or groove filling ratio (GFR) of Fresnel diffraction structure. The data acquisition system is used to integrate these two processes. In the IMMC method, piezoelectric actuator and pressure sensor are used to test with different percentages of peak filling pressure. The VMT method is to switch on the compression air to achieve quick mold cooling after sensing the packing phase signal from the injection molding machine. It is to investigate the effect of different cooling setting temperature (CST) on the quality of molded parts. The Rt can be achieved as 1.29 μm when the mold temperature is set as 100 ℃ in the traditional injection molding. Then experimental results show that the Rt can be achieved as 3.32 μm and the GFR as 96.95% when the mold temperature is set as 120 ℃, the CST of varithermo mold temperature as 80 ℃, and the IMMC method with trigger point as 50% of peak filling pressure. Further research focuses on the replication of hybrid lens array optical elements with micro structures to increase the optical performances.

This research conducted a novel micro injection compression molding (μ-ICM) process for fabrication of hybrid optical elements (HOEs). The micro compression motion is triggered by the percentage of peak filling pressure obtained by the data acquisition (DAQ) system. Experiments were implemented with different percentages of peak fill pressure, and the relationship between the trigger time and transfer ratio of the groove (TRG) were investigated. The Moldflow MPI software (Moldflow Co., USA) is used to simulate the filling and packing stages of HOEs. Comparison of short shot is preceded by simulation and experimentation. Results show that (1) the HOEs are fabricated successfully by the μ-ICM with a closed-loop pressure control, (2) the comparison of short shot is similar in simulation and experiment, (3) the TRG has been achieved as 99% when the trigger pressure is 15% of peak filling pressure with mold temperature 90°C and melt temperature 250°C, (4) the comparison of different mold insert materials show that the STAVAX with electroless plated Nickel (ELNi ) has better TRG than that of the oxygen-free copper (OFC) due to higher hardness of ELNi. Further research focuses on the μ-ICM of optical elements with micro structures to increase the optical performances.

Abstract:
Abstract Injection/compression molding (ICM) is often referred to as coining, stamping, compressive-fill, or hybrid molding. It can produce parts with more homogeneous properties and less molded-in stresses, and this may not be possible with conventional injection molding. It can also produce extremely thin or large parts which may require larger machine if conventional injection molding were used. A CAE software has been developed to simulate the ICM process. Two areas will be emphasized to show the advantage of the ICM process over the conventional injection molding process. One is the opening of the mold halves during the molding process allows resin flow to proceed to the extremities of the cavity more easily and consequently reduces the injection pressure and clamping force. Process window design will be discussed. The other is the packing due to the compression motion requires less pressure gradient, i.e., more effective packing. It results in more uniform and smaller pressure throughout the entire cavity. This is essential to produce parts with low residual stress such as compact disk and lens.

Abstract:
This study dealt with the effect of hybridization of jute fiber and glass fiber on the mechanical properties of fiber reinforced thermoplastics injection moldings. In the glass/jute hybrid materials the weight fraction of glass fiber was fixed at 10wt% and that of jute fiber was varied from 5wt% to 30wt%. Dumbbell-shaped specimens were prepared by injection molding, and the static tensile tests were performed with acoustic emission (AE) monitoring. AE monitoring was conducted to understand the fracture behaviors of glass/jute hybrid materials. By adding the glass fiber to jute fiber reinforced plastics the tensile strength was improved. However, too much content of jute fiber could not achieve the improvement of strength because the uniform distribution of glass fiber was restricted by too much bulky jute fiber. After tensile test the fiber distribution on the fracture surface was observed. Based on the fiber distribution of jute fiber and glass fiber the strength prediction was attempted by introducing the rule of mixture.

Tooling was evaluated based on the ease of melt filling and part ejection; the replication quality as characterized using optical profilometry, confocal microscopy, and scanning electron microscopy; and the damage to the tooling after repeated use. With lower aspect ratio features, the tooling type did not significantly affect replication, but for higher aspect ratio features the hybrid tooling provided far better replication than the silicon tooling. This difference was attributed to retardation of heat transfer in the features of the hybrid tooling. All three tooling materials exhibited polymer-free surfaces after injection molding.

Abstract:
The noise and vibration problems created by injection molding machines can be moderated by the installation of absorbers. The pull rods of the machine, which are guided to the molding movements, might be a better location for mounting a spring, rubber or hybrid elastomer for energy absorption and reduction of noise and vibration. In this paper, some special washers are designed to fit the guide rods and performance tests are carried out. The results show that noise and vibration decreased over 10 dB and 2 times, respectively.

Abstract:
This paper mainly discusses the effect of coupling on the tensile properties of glass fiber (GF)/carbon fiber (CF) reinforced polypropylene (PP) hybrid composites which were made through a new injection molding process named direct fiber feeding injection (DFFIM) process. It is mainly divided into two parts which discusses the functional of coupling agent in the composites system, and the different contents of coupling agent (PA6 and MAPP) on the tensile properties of composites. DFFIM progress is a new method that by directly feeding of continuous carbon fiber into the barrel of injection molding machine to make the hybrid composites. The continuous CF roving strands are guided into the vent of devolatilizing unit of injection barrel and fed into the melt by the shearing motion of the screw during plasticization process. By using DFFIM process to make composites, the fiber attrition during extrusion compounding will be eliminated. It is a great improvement in reduction of material cost. And also the cost of reinforcing compounded pellet in the traditional composites market value chain could be lower. Polyamide 6 (PA6), Maleic anhydride-grafted polypropylene (MAPP) or both of them were mixed with pellets during the DFFIM process and PA6 and MAPP were used as coupling agent for CF/GF reinforced PP system. The CF and GF contents in each hybrid composites were tested to analysis the influence of fiber contains on the tensile properties of composites. Usually, better interfacial bonding between fiber and matrix in composites, better tensile properties of composites. So the effect of coupling agent (PA6 and MAPP) on the interfacial bonding between CF and PP in hybrid composites were firstly analyzed. And then the influence different contents of PA6 and MAPP on the tensile properties of GF/PP composites and GF/CF reinforced PP hybrid composites were investigated. It is found that the addition of PA6 did not improve the interfacial bonding but the addition of MAPP has shown a little improvement to the bonding between CF and PP. And when using PA6 and MAPP together as co-coupling agent, the tensile properties of composites has greatly increased. And, there is fiber aggregation in the core layer of the hybrid composites which made by DFFIM process, while there is no such phenomenon happened in the condition of normal injection molding process. It is the main reason that the tensile strength of hybrid composites without coupling agent is weaker than the GF/PP composites. And the tensile modulus of composites would be increased considerably. That is due to the addition of the carbon fiber which has high tensile modulus. In the condition of composites with 1wt.% PA6, the 1wt.% PA6 shows positives effect on tensile properties and while PA6 has negative role when the amount of PA6 has improved. Within a certain range, the larger amount of MAPP in the system of MAPP-PA6 composites, the better on the tensile properties of composites is. And MAPP has positive effect on the tensile properties of composites.

Abstract:
Lightweight design for automotive applications gains more and more importance for future products, independent from the powertrain concept. One of the key issues in lightweight design is to utilize the right material for the right application using the right value at the right place. This results irrevocably in a multi-material design. In order to increase the efficiency in manufacturing car components, the number of single parts in a component is decreased by increasing the complexity. Examples for the state of the art are tailored welded blanks in cold forming, tailored tempering in press hardening or metallic inlays in injection molding of polymers. The challenge for future production scenarios of multi-material components is to combine existing technologies for metal- and polymer-based applications in efficient hybrid process chains. This paper shows initial approaches of hybrid process chains for efficient manufacturing of hybrid metal-polymer components. These concepts are feasible for flat as well as for tubular applications. Beside the creation of the final geometric properties of the component by a forming process, integrated joining operations are increasingly required for the efficiency of the production process and the performance characteristics of the final component. Main target of this production philosophy is to create 100% ready-to-install components. This is shown in three examples for hybrid process combinations. The first example deals with the combination of metal forming and injection molding of polymers. Example number two is the application of hybrid metal-polymer blanks. Finally, example number three shows the advantages of process integrated forming and joining of single basic components.
