【Delivery Achievements: Products for Electronics and Semiconductors】 - Heat-resistant and chemical-resistant O-rings (FFKM) - Seals for semiconductor manufacturing equipment/analysis testing equipment - Seals for mass flow controllers (FKM/NBR/EPDM/CR) - Seals for vacuum plasma equipment (NBR) While there is a cry for a shortage of rubber raw materials, fluororubber (FKM) and silicone rubber (Si) are gradually becoming available, and we are also supplying a significant amount of EPDM, which has been a concern regarding supply volume. If you are having trouble procuring O-rings or various seal gaskets, please feel free to contact us, as we are capable of press manufacturing under a two-shift system!

We assist in the design and mass production of custom-made products tailored to customer requests! Here, we introduce the delivery achievements of Seiwa Sangyo Co., Ltd.'s seal products. We have supplied various automotive and construction machinery products, including X-rings (FKM) for viscous couplings and seals (FKM) for starters. We manufacture large quantities of automotive products at Holon Seiko Co., Ltd., which operates 24 hours a day, starting from small lot products. In addition, we have numerous delivery achievements for industrial, electronic/semiconductor, and medical/food equipment products. 【Delivery Achievements (Partial)】 <Automotive/Construction Machinery Products> ■ X-rings (FKM) for viscous couplings ■ Seals (H-NBR) for car air conditioner compressors ■ Seals (FKM) for brake valves ■ Seals (FKM) for starters ■ Seals (EPDM) for radiators

We specialize in the production of resin machining products that are extremely difficult to machine in three-dimensional shapes or require high dimensional accuracy. 【Business】 Seiwa Sangyo Co., Ltd. manufactures synthetic rubber/resin seal (packing) products and sells mass-produced items ranging from single prototypes to tens of thousands of units to a wide range of customers nationwide. 【Machining Capabilities】 We can handle materials from the five major engineering plastics to super engineering plastics such as PEEK and PTFE. If you send us your drawings, we will confirm whether production is possible, and if so, we will provide you with a quotation. Please feel free to contact us.

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!

We will be exhibiting at the 25th Kansai Manufacturing World held at Intex Osaka. This exhibition aims to contribute to the manufacturing industry in areas such as "short-term development, productivity improvement, quality enhancement, VA/VE, and cost reduction," and is composed of nine exhibitions. The main exhibited products include IT, DX products, components, equipment, devices, and measurement products used in the manufacturing industry. We sincerely look forward to your visit.

Our company will be exhibiting at the "Mechanical Components Technology Exhibition" held at Tokyo Big Sight. This exhibition showcases mechanical parts such as motors, bearings, screws, and springs, as well as processing technologies like cutting and pressing, and surface treatment. Every year, a large number of users from design, development, prototyping, manufacturing, production technology, and purchasing departments visit the exhibition to engage in business discussions with exhibiting companies. We sincerely look forward to your visit.
