The cold extrusion forming of stainless steel seamless elbow is to use a special elbow forming machine to put the tube blank into the outer mold. The gap movement completes the forming process.
The elbow made by the cold extrusion process of the inner and outer molds has the advantages of beautiful appearance, uniform wall thickness and small size deviation.
Therefore, stainless steel elbows (especially thin-walled stainless steel elbows) are mostly manufactured by this process. However, this process has high requirements on the precision of the inner and outer molds used, and also has strict requirements on the wall thickness deviation of the tube blank.
The above is the introduction of cold extrusion forming process of stainless steel seamless elbow.
