Process Optimization for Compression Molding of Carbon Fiber–Reinforced Thermosetting Polymer

The 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...

Finding efficient frontier of process parameters for plastic injection molding

Product quality for plastic injection molding process is highly related with the settings for its process parameters. Additionally, the product quality is not simply based on a single quality index, but multiple interrelated quality indices. To find the settings for the process parameters such that the multiple quality indices can be simultaneously optimized is becoming a research issue and ...

Optimization of TQFP molding process using neuro-fuzzy-GA approach

This paper focuses on an integrated optimization problem that involves multiple qualitative and quantitative responses in the thin quad flat pack (TQFP) molding process. A fuzzy quality loss function (FQLF) is first applied to the qualitative responses, since the molding defects cannot be simply represented by the relationship between molding conditions and mathematical models. Neural network i...

Effective Run-In and Optimization of an Injection Molding Process

Adaptive Multi-objective Optimization of Process Conditions for Injection Molding Using the Gaussian Process Approach

This paper presents an integrated simulation-based optimization system that incorporates the design of computer experiments, the Gaussian process (GP) for regression, a multi-objective genetic algorithm (GA), and levels of adjacency to adaptively and automatically search Pareto-optimal solutions for different objectives. Selecting the optimal process conditions for the injection molding process...
