In this technology development, we have developed an automation system after developing a material rotation mixing process so that the manual process of sound absorbing materials can be supplied in quantities. After setting up 5kgf supply of the fused acoustic material, the setting value of 5kg was automatically supplied to the molded frame to reach the quantification supply. In the process of producing noise goods between floors, the automatic compression system was developed, which was a manual operation of three persons, and the production of one person was allowed, and the production of 200 sound absorbers per day, It has improved to 450. Quantitative supply unit was developed to reach 50.7mm for target 50±3mm based on the sound absorption product thickness indication, reducing the defect rate to less.
