AUTOMATIC WELDING MACHINE FOR SUPPLYING COILS CONTINUOUSLY USING PRESS-IN ROLL AND WELDING ROLL
The present invention provides a manufacturing method of a sound absorption material with improved sound insulation performance using recycled plastic. The manufacturing method of a sound absorption material comprises: a first process of preparing recycled plastic; a second process of pulverizing the recycled plastic; a third process of washing and drying the pulverized recycled plastic; and a fourth process of extruding and molding the washed and dried recycled plastic.
재활용 플라스틱을 이용하여 방음성능이 향상된 흡음재의 제조방법을 제공한다. 상기 흡음재의 제조방법은 흡음재를 제조하는 방법에 있어서, 재활용 플라스틱을 준비하는 제1공정; 재활용 플라스틱을 분쇄하는 제2공정; 분쇄된 재활용 플라스틱을 세척 및 건조하는 제3공정; 세척 및 건조된 재활용 플라스틱을 압출 및 성형하는 제4공정을 포함하는 것을 특징으로 한다.
