With assembly-free PFA welding, highly flexible designs are possible, achieving compactness and space-saving for piping components! *Product examples will be introduced.
Our unique PFA welding technology allows for direct connection between fittings and the joining of tubes to machined manifolds, forming a piping structure. - Directly connecting fittings has made the piping more compact. - 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. - The combination of welding with machined parts enables multi-port manifolds to be realized in small diameters (Φ4 and above). - The reduction in the number of parts has led to cost savings. - We can accommodate everything from small quantities to mass production through combinations with machining and injection molding.

basic information
**Introduction to PFA Beadless Welding Technology** ◎ Unique Beadless Welding This is our proprietary welding technology that minimizes the bead (the raised part of the joint) formed on the inside of the welded area. With beadless welding, the purgeability of the welded section inside the pipe is improved, enhancing liquid displacement and achieving high cleanliness! ◎ High Reliability! Clean Finish Thanks to NC control, the reproducibility of the welding process is high, 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 terms of strength and leak resistance. ◎ Space-Saving and Compact Design By combining standard fittings and machined parts with tubes for welding, we enable a high degree of design flexibility, allowing for the compactness and space-saving of piping components. **Solving These Issues!** ■ Adhesives are causing impurities to leach out ■ Want to reduce the number of components in piping parts or make them more compact ■ Want to shorten installation time for tubes and fittings ■ Want to address liquid leakage from connection points

Detailed information
-
【Molded Fittings + Tube Branch Piping】 We can accommodate mass production through the 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 a compact multi-way manifold. Since machined parts do not require molds, we can also accommodate the production of small lot items.
-
【Manifold Joint】 By combining unique welding processes, shapes that cannot be achieved by injection alone are realized. Compared to conventional piping connections such as elbows and tees, a 70% reduction in size is possible, 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.
