Up to 70% smaller! Achieve downsizing of piping structures with weld-free piping that requires no assembly.
Through our unique PFA welding technology, we directly connect fittings to each other and join tubes to machined manifolds, forming a piping structure. - Fittings are directly connected, resulting in a more compact piping system. - Assembly is no longer required, reducing assembly labor. - There are no leaks due to the connection between fittings and tubes or the switch from welded piping. - By combining with machined products, multi-port manifolds can be achieved even in small diameters (Φ4 and above). - The number of parts has been reduced, leading to cost savings. - We can accommodate everything from small quantities to mass production by combining with machining and injection molding.

basic information
**Introduction to PFA Beadless Welding Technology** ◎ Unique Beadless Welding Our proprietary welding technology minimizes the bead (the raised part of the joint) that forms on the inside of the welded area. With beadless welding, the purging of contaminants in the welded section of the pipe is improved, enhancing liquid replacement and achieving high cleanliness! ◎ High Reliability! Clean Finish The reproducibility of the welding process is high due to NC control, making it suitable for mass production. Additionally, compared to traditional welding, there is less variation, and the joint is completely integrated, allowing for connections with high reliability in strength and leak resistance. ◎ Space-Saving and Compact Design By combining standard fittings, machined parts, and tubes through welding, we enable highly flexible designs, allowing for the compactness and space-saving of piping components. **Solving These Concerns!** ■ Adhesives are used, but impurities are leaching out ■ Want to reduce the number of piping components or make them more compact ■ Want to shorten the installation time for tubes and fittings ■ Want to address liquid leakage from connection points

Detailed information
-
Molded fittings + branching piping of tubes We can accommodate mass production through a combination with injection molding. We provide total support from prototype development in the conceptual stage to mass production.
-
【4-way manifold component】 By combining with machined parts, it is possible to manufacture multi-way manifolds in a compact form. Since machined parts do not require molds, we can also accommodate the production of small lots.
-
【Manifold Joint】 By combining our unique welding process with injection molding, we achieve shapes that are impossible with injection alone. Compared to traditional pipe joints such as elbows and tees, we can achieve a 70% reduction in size, contributing to a more compact piping space. Our unique technology, Beadless WeldingⓇ, creates a smooth inner surface with minimal irregularities, alleviating concerns about leaks and enhancing reliability.
