住吉化成 Company Profile

Manufacturing through handcrafting

Sumiyoshi Kasei Co., Ltd. produces processed and molded products made from various types of foams, primarily polyurethane and polyethylene, supplying materials to a wide range of industries through meticulous "monozukuri" (craftsmanship). Our production process, based on "handmade" principles, is structured to meet various needs. We aim to create a unique domain of "handmade" that aligns with the times by not only passing down the technologies we have cultivated over many years but also infusing them with new sensibilities.
