We have filed a patent for a pipe joining method and pipe joint that allows for a high strength of the joint and ensures airtightness by directly joining the base materials without using a filler material.

We have filed a patent for a pipe joining method and pipe joint that allows for a high strength at the joint between pipes and ensures airtightness in the joining of thin-walled pipe curved surfaces.

Porta Park Co., Ltd. has adopted our technology for the prototype of the air conditioning functional building materials' flow path components currently under development. The heat exchange panel, which encapsulates the principle of "summer cooling through water sprinkling," requires the maintenance of a vacuum state for an extended period. We have adopted "airtight projection welding" technology for the water vapor flow path components that require high airtightness.

We have named our unique technology, which ensures high joint strength and high airtightness through projection welding, "Airtight Projection" and have applied for a trademark.
