Large-diameter O-rings can be manufactured at low cost and with short lead times!
Our company specializes in the production of large-diameter sealing materials using a process called "continuous baking molding." Continuous baking molding is a technology that allows for the molding of special dimensions not covered by JIS or AS standards. It does not require molds for single items or small lots, enabling the production of large-diameter O-rings at low cost and with short lead times. Since we use various dedicated facilities for continuous baking molding, the finish, appearance, and dimensional accuracy are stable. Additionally, we use the same materials as standard products, eliminating the occurrence of issues. 【Features】 ■ No mold costs if using our owned molds ■ Performance equivalent to that of general molded products due to mold molding ■ Almost invisible seams due to vulcanized bonding ■ Custom sizes can be produced starting from one piece, according to customer requests *For more details, please download the PDF or feel free to contact us.
