Neural Modeling of Parison Extrusion in Extrusion Blow Molding
Back-propagation (BP) neural network is used to develop process models for the parison extrusion in extrusion blow molding based on experimental data. In applying the BP network, some modifications, such as using a self-adaptive learning rate coefficient, determining the number of hidden neurons through experimentation, and so on, to the original BP algorithm are carried out to speed up learnin...
متن کاملThe Numerical Analysis and Validation of Compression Molding Process
In this work, the simulation results from a program developed for the three-dimensional analysis of compression molding of thermoset composites were compared to the experimental results of an actual molded thermoset sample. The program predicts the flow pattern, fiber orientation, fiber length distribution, curing of the resin and mechanical properties. The comparison between simulation and exp...
متن کاملOptimization of extrusion blow molding processes using soft computing and Taguchi's method
The objective of this study is to present a new numerical strategy using soft computing techniques to determine the optimal die gap programming of extrusion blow molding processes. In this study, the design objective is to target a uniform part thickness after parison inflation by manipulating the parison die gap openings over time. To model the whole process, that is the parison extrusion, the...
متن کاملOptimization of Extrusion Blow Molding Using Soft Computing and Taguchi Method
This paper presents a soft computing strategy to determine the optimum die openings of parison programming of extrusion blow molding process. The design objective is to obtain a uniform thickness of blown parts. The proposed strategy, Fuzzy Neural-Taguchi, first establishes a back propagation network using Taguchi’s experimental array to predict the relationship between design variables and res...
متن کاملHigh Performance Compostable Biocomposites Based on Bacterial Polyesters Suitable For Injection Molding and Blow Extrusion
Nowadays, there is an increasing interest toward the substitution of oil-based polymers with biobased polymers. Poly(hydroxyalkanoates) (PHAs) emerge as a new class of biopolymers, that have gained more and more attention due to their thermoplastic behaviour, acceptable mechanical properties and biodegradability in compost conditions1. Applications based on PHAs, as a matrix, are generally foun...
