WARM WATER DISTRIBUTOR MANUFACTURE METHOD FOR HEATING

摘要

A method of manufacturing manifolds is provided to eliminate a spot welding process and an embossing process for improving productivity and reducing defects. A method of manufacturing manifolds which distribute warm water to places required for heating includes a step(100) of piercing more than one hole for inserting sockets with a diameter bigger than the outer diameter of sockets; a step(200) of placing sockets under the pierced hole, inserting sockets into the pipe, and pushing out the socket outwardly so that the sockets are protruded from the hole with a certain height; and a step(300) of welding joints made by the sockets and the pipe.
