| Abstract | Quality is an important problem in any gypsum board
manufacturing system. This study :L s concerned witl1 t h e us e o:E
statistical techniques to analyze the quality problem of gypsum
board in Siam Fibre-cement Co. , Ltd.
The existing quality control activities of this company have
been studied. A major problem is the uneven surface board caused
by the poor quality of paper. So the main objective o f the
present study is to set the best level of each important paper
quality characteristic for producing good quality board.
Taguchi ' s method is used for conducting experimental design
to set the best levels. Signal to noise ratio is used as the
performance statistic in the analysis of variance. The best level
of paper qu ality characteristics are set to reduce the variation
of gypsum board quality from the target value.
The min or objectives of this study are the testing for
uniformity in order to measure the consistency of paper quality
throughout the roll and the testing for validating of the vendor
sample for representing the samples of the company to reduce loss
from the existing sampling procedure.
Some discussions and recommendations are presented to serve
as guidelines towards possible improvements and further studies
in the future. |
