Type IV tank liners are made of lightweight resin and have excellent corrosion resistance. The material used is plant-based PA11, which not only ensures gas barrier properties but also contributes to achieving carbon neutrality. By integrating the liner through rotational molding, we can achieve uniform wall thickness and strength even in large-capacity, long products. Additionally, development can be completed in a shorter time compared to injection molding. Furthermore, capital investment costs can be significantly reduced. Our company can suppress harmful voids through our unique active vent technology.

MCF molding (ultrafine foaming molding) is a molding method that utilizes ultrafine foaming. It is adopted in various fields, including automotive and OA equipment parts produced by our company.
