Vacuum Thermoforming Process: An Approach to Modeling and Optimization Using Artificial Neural Networks

In the vacuum thermoforming process, the group effects of the processing parameters, when related to the minimizing of the product deviations set, have conflicting and non-linear values which make their mathematical modelling complex and multi-objective. Therefore, this work developed models of prediction and optimization using artificial neural networks (ANN), having the processing parameters set as the networks’ inputs and the deviations group as the outputs and, furthermore, an objective function of deviation minimization. For the ANN data, samples were produced in experimental tests of a product standard in polystyrene, through a fractional factorial design (2k-p)…

One Company’s Sustainability Journey to Zero Waste

Sekisui Chemical’s Zero Emissions Program
Zero emissions is a designation by Sekisui Chemical. This rigorous program was started in 1998 to make all Sekisui facilities “zero waste to landfill” within five years of becoming a Sekisui Chemical company. To date, 12 factories have earned the designation.

Being good stewards of the planet and community has always been a part of SEKISUI SPI’s business philosophy, history, and culture, so achieving zero emissions was a natural step in their environmental efforts. In 2010, SEKISUI SPI began its journey towards zero emissions by creating a cross-departmental team tasked with conducting an in-depth audit of its processes and materials…
