How is Seamless elbow made | Longrun

 The production of seamless elbow mainly adopts the hot push technology.Hot push elbow forming technology is to use special elbow push system core machine, mold and heating device, to set on the mould of billet in pushing forward movement, under the impetus of the machine in motion is heated and hole enlargement and forming process.Hot push elbow deformation characteristics are based on volume before and after plastic deformation rule of metal materials determine the pipe diameter, pipe diameter elbow diameter, through the core module and control the deformation of the process, make the inner arc compressed metal flow, the compensation to other parts of the thinned by hole diameter, wall thickness uniform Angle is obtained.
