Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Reactive in-mold coating (IMC) products have been used successfully for many years to improve the surface quality of Sheet Molding Compound (SMC) compression molded parts. IMC provides a smooth, sealed surface, used as a conductive or nonconductive primer for subsequent painting operations. The success of IMC for SMC parts has recently attracted the interest of thermoplastic injection molders. The potential environmental and economic benefits of using IMC as a primer and, in the ideal case, to replace painting completely are large. Acceptance of IMC as a competitor to the traditional painting processes will depend upon the improvement of its ability to deliver in-mold coated parts in short cycle times at the highest possible quality level. Most optimization studies in Reactive Polymer Processing involve compromising between different performance measures since, frequently, the controllable variables have conflicting effects on these measures. IMC is not the exception to the rule. The performance measures need to be balanced, each against the other, in order to obtain the best compromises. The goal of this research work is to develop an optimization strategy for the application of reactive in-mold coating to SMC and thermoplastic parts in presence of multiple and conflicting performance measures. To achieve this goal we explore the use of Artificial Neural Networks as metamodeling techniques and the use of Data Envelopment Analysis to solve multiple criteria optimization problems.

Book Synopsis Experimental investigation and process simulation of the compression molding process of Sheet Molding Compound (SMC) with local reinforcements by : Hohberg, Martin
Download or read book Experimental investigation and process simulation of the compression molding process of Sheet Molding Compound (SMC) with local reinforcements written by Hohberg, Martin and published by KIT Scientific Publishing. This book was released on 2022-04-05 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, a new three-dimensional approach for the process simulation of SMC is developed. This approach takes into account both, the core layer that is dominated by the extensional viscosity and the thin lubrication layer. In order to transfer the information from the process to the structure simulation, a CAE chain is further developed. In addition, a new rheological tool is developed to analyze flow behavior experimentally and to provide the required material parameters.

Book Synopsis Mathematical Modeling of the In-mold Coating Process for Injection Molded Thermoplastic Parts by : Xu Chen
Download or read book Mathematical Modeling of the In-mold Coating Process for Injection Molded Thermoplastic Parts written by Xu Chen and published by . This book was released on 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: In-Mold Coating (IMC) has been successfully used for many years for exterior body panels made from compression molded Sheet Molding Compound (SMC). The coating material is a single component reactive fluid, designed to improve the surface quality of SMC moldings in terms of functional and cosmetic properties. When injected onto a cured SMC part, IMC cures and bonds to provide a pain-like surface. Because of its distinct advantages, IMC is being considered for application to injection molded thermoplastic parts. For a successful in mold coating operation, there are two key issues related to the flow of the coating. First, the injection nozzle should be located such that the thermoplastic substrate is totally covered and the potential for air trapping is minimized. The selected location should be cosmetically acceptable since it most likely will leave a mark on the coated surface. The nozzle location also needs to be accessible for easy of maintenance. Secondly, the hydraulic force generated by the coating injection pressure should not exceed the available clamping tonnage. If the clamping force is exceeded, coating leakage will occur. In this study, mathematical models for IMC flow on the compressible thermoplastic substrate have been developed. Finite Difference Method (FDM) is first used to solve the 1 dimensional (1D) IMC flow problem. In order to investigate the application of Control Volume based Finite Element Method (CV/FEM) to more complicated two dimensional IMC flow, that method is first evaluated by solving the 1D IMC flow problem. An analytical solution, which can be obtained when a linear relationship between the coating thickness and coating injection pressure is assumed, is used to verify the numerical results. The mathematical models for the 2 dimensional (2D) IMC flow are based on the generalized Hele-Shaw approximation. It has been found experimentally that the power law viscosity model adequately predicts the rheological behavior of the coating. The compressibility of the substrate is modeled by the 2-domain Tait PVT equation. CV/FEM is used to solve the discretized governing equations. A computer code has been developed to predict the fill pattern of the coating and the injection pressure. A number of experiments have been conducted to verify the numerical predictions of the computer code. It has been found both numerically and experimentally that the substrate thickness plays a significant role on the IMC fill pattern.
Book Synopsis Handbook of Molded Part Shrinkage and Warpage by : Jerry Fischer
Download or read book Handbook of Molded Part Shrinkage and Warpage written by Jerry Fischer and published by William Andrew. This book was released on 2012-12-31 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: How easy life would be if only moldings were the same size and shape as the mold. But they never are, as molders, toolmakers, designers and end users know only too well. Shrinkage means that the size is always different; warpage often changes the shape too. The effects are worse for some plastics than others. Why is that? What can you do about it? The Handbook of Molded Part Shrinkage and Warpage is the first and only book to deal specifically with this fundamental problem. Jerry Fischer’s Handbook explains in plain terms why moldings shrink and warp, shows how additives and reinforcements change the picture, sets out the effect of molding process conditions, and explains why you never can have a single ‘correct’ shrinkage value. It goes on to demonstrate how to alleviate the problem through careful design of the molded part and the mold, and by proper material selection. It also examines computer-aided methods of forecasting shrinkage and warpage. And most important of all, the Handbook gives you the data you need to work with. Authoritative and rooted in extensive industrial experience, the expert guidance contained in this handbook offers practical understanding to novices, and new insights to readers already skilled in the art of injection molding and mold making Contains the answers to common problems and detailed advice on how to control mold and post-mold shrinkage and warpage Case Studies illustrate and enrich the text; Data tables provide the empirical data that is essential for success, but hard to come by
