Pengujian dan Pengukuran Perubahan Coating Liquid Flow Rate dan Coating Time Duration Terhadap Hasil Coating Quality Angle Mesin Diener Tetra 100
One of the things that become a benchmark for the quality of a product is that the product complies with specifications and there are no production defects. Diener Tetra 100 machine is used to produce Housing top, Housing Bottom, Rocker switch, Battery door, push-button, and T. Coil. Usually, the Diener Tetra 100 machine product is often rejected due to dirty, incorrect parameter settings, and unacceptable coating heating levels. This research examines the effect of changing the Diener Tetra 100 machine parameters and checking measurements on the coating results. This study aims to obtain the optimal value of the coating liquid flow rate and the coating spraying time (time duration). This research was conducted by varying the parameter settings for coating liquid flow rate, coating time duration, and temperature chamber, where the independent variables were Time duration 10 minutes, 30 minutes, 45 minutes, and the independent variables were coating liquid flow rate, 70 ml/second, 100 ml. /second, 130 ml/second, with the same Temperature Chamber 60oC. Based on the results obtained in this study, found three optimal parameters on the Diener Tetra 100 machine. Among them were is the Coating Time Duration 45 minutes and coating liquid Flow rate 70 ml/second; Time Duration Liquid 30 minutes and Coating liquid flow rate 100 ml/second; Time Duration of Liquid is 10 minutes, and coating, liquid flow rate, is 130 ml/second because the percentage of product rejects obtained from the results of this study is low.
