A taguchi method for safety design of artificial marble products

Artificial marble products usually include sinks and kitchen equipments. Frequent accidents of consumer injuries caused by fallen sinks have been reported. This study aims to enhance the safety of marble sink by taking into the consideration of not increasing the cost of production and materials, and by applying the parameter design of Taguchi Method in selecting six controllable factors: defoaming time, resin ratio, hardener amount, oven time, oven temperature and amount of transparent glue. Eventually by formulating the optimal combination of production parameters, and by adjusting the raw materials and process, human injuries resulted from broken sink shreds may be avoided. All confirmation experiments conducted by parameter level fall within the confidence interval, indicating the parameter design of this study can actually attain the ultimate goal of product safety by effectively enhancing product quality without increasing any related costs.
