泉シール工業 List of Products and Services

Our company conducts impregnation treatment and trivalent chromate treatment for metal die-cast and cast products. To address pressure leaks and water leaks caused by casting defects in pressure-resistant parts, we apply impregnation treatment (sealant treatment) to prevent defects (leaks) and also expect improvements in corrosion resistance. Among the impregnation methods, we have adopted the "organic vacuum pressure impregnation method," and we use "Rexeal 100" from Ultra Seal, which is recognized and certified worldwide. It has formal certification under [MIL-I-17563C]. We believe this is the most effective method currently available for achieving sealing effects. By applying impregnation treatment to sudden defective products caused by casting defects, we add value to the products themselves and improve corrosion resistance while preventing plating blisters through sealing. Many companies are incorporating impregnation treatment into their manufacturing processes, which can significantly reduce costs by decreasing waste and regeneration. Furthermore, we also perform trivalent chromate treatment using "Sartec 650V," which provides corrosion resistance comparable to hexavalent chromium and offers various benefits such as improved adhesion in pre-treatment for painting.

What is the "Organic Vacuum Pressure Impregnation Treatment" that our company conducts? Products are placed in a basket within a vacuum device, and the pressure inside the device is reduced to create a vacuum state. Furthermore, by applying compressed air, the impregnation agent is filled deep into the defective parts of the product, which is referred to as "Organic Vacuum Pressure Impregnation Treatment." Compared to inorganic systems, it excels in sealing properties and water resistance, and this vacuum pressure impregnation method allows the impregnation agent to penetrate even deeper into the voids. *For more details, please download the PDF materials or feel free to contact us.*
