Traditional ceramic commodities pay less attention to standard operating procedures; hence, the quality is less stable. This study employed the Taguchi method to determine the parameter optimization design for ceramics production in an attempt to seek the optimal parametric combination and improve the overall quality of ceramic production. According to literature review and discussion with engineers, the controlling factors of the ceramic production process include filling rate, waiting time for thickening, taking the plaster mold from the ceramic product, and the way of holding the ceramic product. Using the case product as an example, the experimental results showed that the optimal combination of parameters is as follows: 36 seconds for filling, 16 minutes for waiting its thickening, 15 minutes before the plaster mold can be taken out, and the way of holding it is from the bottom. By implementing the above parameters, the yield rate increased from 70% to 94%, which corresponded to expected goals, and therefore, can save cost, increase productive efficiency and improve quality.
