Book Effect of Shrinkage on the Design and Manufacture of Plastic Parts in Injection Molding Using CAD CAM Techniques

Download or read book Effect of Shrinkage on the Design and Manufacture of Plastic Parts in Injection Molding Using CAD CAM Techniques written by Deepak M. Shastri and published by . This book was released on 1991 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computer aided design software in injection molding has revolutionized injection molding in the design and manufacturing processes. Computer Aided Engineering can be applied to injection molding to increase the process efficiency, reduce part costs, and produce accurate parts in less time. The mold designer has many software programs to choose from to produce satisfactory mold designs from part geometries, and a correct selection can produce profitable results. A study of the need for and the scope of computers in injection molding is performed to evaluate the suitability of a CAE package by considering the value added to the parts using these techniques. The interactive nature of the programs is illustrated with examples and also the ability of the programs to perform simulations of the processes axe studied and the accuracy and reliability of the programs is considered. Evaluation of part shrinkage is very important to mold parts of required accuracy. The currently used methods in CAD mold design have one major drawback that mold designers experience. The variation in shrinkage coefficients for different resins cannot be compensated for and one cannot predict whether a specific part can be manufactured without warpage. Most CAD simulations cannot accurately predict the variation in shrinkage rates across all dimensions of a specific part. The factors influencing part shrinkage are studied and the variation of shrinkage with molding conditions is illustrated from previous experiments. A comprehensive plan is suggested to perform experiments to enable prediction of part shrinkage more accurately.

Book Plastics Process Analysis Instrumentation and Control

Download or read book Plastics Process Analysis Instrumentation and Control written by Johannes Karl Fink and published by John Wiley & Sons. This book was released on 2021-03-02 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on plastics process analysis, instrumentation for modern manufacturing in the plastics industry. Process analysis is the starting point since plastics processing is different from processing of metals, ceramics, and other materials. Plastics materials show unique behavior in terms of heat transfer, fluid flow, viscoelastic behavior, and a dependence of the previous time, temperature and shear history which determines how the material responds during processing and its end use. Many of the manufacturing processes are continuous or cyclical in nature. The systems are flow systems in which the process variables, such as time, temperature, position, melt and hydraulic pressure, must be controlled to achieve a satisfactory product which is typically specified by critical dimensions and physical properties which vary with the processing conditions. Instrumentation has to be selected so that it survives the harsh manufacturing environment of high pressures, temperatures and shear rates, and yet it has to have a fast response to measure the process dynamics. At many times the measurements have to be in a non-contact mode so as not to disturb the melt or the finished product. Plastics resins are reactive systems. The resins will degrade if the process conditions are not controlled. Analysis of the process allows one to strategize how to minimize degradation and optimize end-use properties.

Book A Plastic Injection Molding Part Feature Extractor and Design Advisory System

Download or read book A Plastic Injection Molding Part Feature Extractor and Design Advisory System written by Sagil James and published by . This book was released on 2010 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Improving plastic injection molded part design is one of the most challenging tasks over past few years. The impact of plastics on the environment has enhanced the interest in this field. An improvement in plastic product design requires expert manufacturing knowledge to be fed to the designer at the initial design stage itself. This can be accomplished by integrating Design for Manufacturing (DFM) rules with a CAD based Plastic injection molding feature extraction module. This research presents a novel methodology to extract manufacturing features from a plastic injection molded part. The geometric model of the part is converted to a IGES format. The B-Rep model of the part is subsequently regenerated from the IGES file and the relevant features are recognized using a rule-based feature extraction technique. Since the feature extractor uses the CAD neutral IGES file format, it does not require the part to be designed using feature-based design technique. Another important contribution of this research is the development of a methodology to provide design recommendations to the part design using an automated design advisory system. The design advisory system uses a knowledge base of DFM rules, collected from various sources in order to provide design advices. Both the feature extraction and design advisory methodology developed is verified on different plastic injection molded parts.
