"Super J-Light" is made using a unique patented manufacturing method and is a resin-based mat that has received various certifications, including "NETIS" from the Ministry of Land, Infrastructure, Transport and Tourism, as well as "Eco Mark," "Chiba Prefecture Manufacturing," and "Shizuoka Prefecture Recycling." It can withstand a compressive force of approximately 80 tons and is resistant to stains from solvents such as acids, alkalis, and gasoline, allowing for versatile processing. Here, we will introduce a case study of its implementation in a factory (work site). ◆ Case Study of the Introduction of Kyoei Kogyo's Resin Mat "Super J-Light" ◆ In the factory's work area, there is often a need to transport heavy items using carts and forklifts, and they were looking for a solution to protect the floor. They tried laying blue sheets and thin rubber mats, repeatedly conducting running tests with carts, but they couldn't find a satisfactory solution. However, when they tested Kyoei Kogyo's J-Light, they found that the carts loaded with heavy items moved smoothly, and walking was easy, making it very user-friendly! As a result, it was adopted in the work area of the client's headquarters factory! Please download the catalog from the link below or feel free to contact us.

At Keiyo Kogyo Co., Ltd., we carry out a large number of special orders for fittings, prototype production of special fittings, and special processing. Thanks to our proven processing technology for PVC pipes and fittings, we can manufacture pipes and fittings with special shapes. In addition to PVC pipes, we also perform blow molding and special processing of various plastics (such as PP, PE, PVDF, PPS, etc.). If you are considering obtaining special-shaped or small-lot fittings, or prototypes, please feel free to contact us. As an example of special processing at Keiyo Kogyo Co., Ltd., we would like to introduce the "PVDF Pipe Bend." 【Example of Special Processing: "PVDF Pipe Bend"】 - As a fitting for artificial dialysis piping, we traditionally used molded elbows, but there was a challenge where air pockets could cause the retention of impurities, compromising safety and reliability. - As a solution, we undertook the production of large-radius bends. - Secondary processing of PVDF pipes has a high heat resistance, and the temperature range for molding is very narrow at ±5°C, making it difficult to process bends within that range. - We have already had over two years of delivery records with no complaints. For more details, please contact us or download our catalog.

At Keiyo Kogyo Co., Ltd., we carry out a variety of special orders for fittings, prototype production of special fittings, and special processing. Our proven processing technology for PVC pipes and fittings enables the production of specially shaped pipes and fittings. Additionally, we also perform blow molding and special processing of various plastics, not just vinyl chloride pipes (such as PP, PE, PVDF, PPS, etc.). If you are considering obtaining special-shaped or small-lot fittings, or prototypes, please feel free to contact us. As an example of special processing at Keiyo Kogyo Co., Ltd., we would like to introduce "blow-molded PVC pipe products." 【Example of Special Processing: "Blow-Molded PVC Pipe Products"】 ○ We received a request for molded products to create a slope within a limited space for fittings used in underfloor piping. → Due to the inability to fit conventional injection-molded fittings like elbows in that space, we proposed a prototype of a bending fitting with a pipe diameter R. ○ We accepted a request for prototype processing of compact-sized drainage fittings. → The R is approximately 40R for a bending section with a pipe diameter of 60, and it was delivered as a prototype since other companies were unable to produce it.

Branch extraction fusion processing refers to the technology of fusing multiple branch pipes to PE pipes. We have developed a dedicated automatic fusion machine by understanding the optimal fusion conditions. Conventional stainless steel options are high in both reliability and cost, and using molded products comes with design limitations. With our "PE header pipe branch fusion technology," we can provide fused branch pipes with high reliability and low cost. ★ This is a fused branch pipe made from the difficult-to-process PE100. After conducting pressure tests, it showed no water leakage at a pressure of 2.5 MPa for 2 minutes! This low-cost fused branch pipe was made possible by the development of a dedicated automatic fusion machine through understanding the optimal fusion conditions. 【Features】 ■ Lower cost compared to continuous tee pipes ■ Can accommodate a larger number of branches ■ Branch pipe connections can be made using either EF connections or mechanical connections ■ PE pipes are lightweight, allowing for wall installation ■ Provides uniform pressure compared to branch pipe methods 【Recommended for!】 ◎ Those looking for compact unit piping ◎ Those wanting to introduce branch pipes at low cost ◎ Those struggling with corrosion in steel pipes ◎ Those considering switching to plastic pipes with excellent seismic resistance ◎ Those wanting to expand design flexibility ● For evaluation examples and application examples, please download and view the catalog.
