From prototype and small lot production, we manufacture rubber product prototypes without the need for molds / Seiwa Sangyo Co., Ltd.
Our company manufactures products from rubber materials through cutting processes, allowing us to produce from a single piece without the need for a prototype mold. Video viewing is also available! Seiwa Sangyo Co., Ltd. manufactures synthetic rubber/resin seals (gaskets) and sells mass-produced items ranging from single prototypes to tens of thousands of units to a wide range of customers nationwide. If you send us your drawings, we will confirm whether production is possible, and if so, we will provide a quotation. 【Features】 ■ Reduces molding defects and material loss ■ High quality and high performance ■ Contributes to cost rationalization
We respond to customer needs with materials ranging from standard to special rubber.

High heat resistance and high hardness chrome plating "Cloamore"
It has an amorphous structure and possesses different characteristics from conventional crystalline chrome plating. Through heat treatment, its hardness can reach a maximum of HV1800, which is about twice that of hard chrome plating. While both Kuroamoru and hard chrome plating experience a softening of hardness when used at high temperatures, Kuroamoru, having reached its maximum hardness through heat treatment, can maintain a hardness of around HV1000 even when used at 600°C. Additionally, once hard chrome plating has been used at high temperatures and its hardness has softened, it does not fully return to its original hardness even when brought back to room temperature. In contrast, Kuroamoru returns to its original hardness each time it is brought back to room temperature, making it highly suitable for use in extremely high-temperature environments. Furthermore, it does not have cracks on the surface like hard chrome plating, which enhances its corrosion resistance, with the corrosion rate against hydrochloric acid being 1/3 to 1/6 that of hard chrome plating. *Free samples are also available. *Please feel free to contact us.
We can manufacture large-diameter O-rings for delivery in as little as 3 days (standard delivery time is 1 to 2 weeks). We have experience with inner diameters from φ220 to a maximum of φ6500.
