A New Injection Molding Method for Highly-Precise Plastic Optical Elements

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 ...

Spiral and conformal cooling in plastic injection molding

Designing cooling channels for the thermoplastic injection process is a very important step in mold design. A conformal cooling channel can significantly improve the efficiency and the quality of production in plastic injection molding. This paper introduces an approach to generate spiral channels for conformal cooling. The cooling channels designed by our algorithms has very simple connectivit...

Nasoalveolar Molding: A new Method for Cleft Lip and Palate Rehabilitation

Introduction: Cleft lip and palate is a congenital anomaly occurring in 3 in 1000 live birth. One the major concern in this patient is about cleft gap and its surgical problems. Several surgical and non-surgical procedures have been done to decrease this gap. They aimed to achieve the more esthetic results as well as feeding success. Nasoalveolar Molding (NAM) is a new method for reshaping nasa...

A neural network-based approach for dynamic quality prediction in a plastic injection molding process

This paper presents an innovative neural network-based quality prediction system for a plastic injection molding process. A self-organizing map plus a back-propagation neural network (SOM-BPNN) model is proposed for creating a dynamic quality predictor. Three SOM-based dynamic extraction parameters with six manufacturing process parameters and one level of product quality were dedicated to trai...
