プラス産業 Company Profile

Leave the manufacturing of vibration plates (cone paper) to us.

Our company is an acoustic component manufacturer that primarily produces diaphragm (cone paper), which has become rare in Japan. We handle everything from raw material development for the diaphragm, which is essential for sound transmission, to prototyping and mass production at our own factory. Utilizing our unique technology to mold paper into three-dimensional shapes, we are also working on the production of innovative three-dimensional paper goods, packaging, and paper products as alternatives to plastic.
