Low price 90D Elbow LR products tell you that stamping forming elbow is the earliest forming process used in the mass production of seamless elbows, and has been replaced by the hot push method or other forming processes in the production of elbows with common specifications. Low price 90D Elbow LR products tell you that, but in certain specifications of the elbow due to the small production quantity, too thick or too thin wall thickness. It is still used when the product has special requirements. The stamping forming of the elbow adopts a tube blank with the same outer diameter as the elbow, which is directly pressed and formed in the mold by a press.

Low price 90D Elbow LR products tell you that before stamping, the tube blank is placed on the lower die, the inner core and end die are loaded into the tube blank, and the upper die moves downward to start pressing, through the constraints of the outer die and the support of the inner die The action makes the elbow shape.
Low price 90D Elbow LR products tell you that compared with the hot push process, the appearance quality of stamping is not as good as the former; when the stamping elbow is formed, the outer arc is in a stretched state, and there is no extra metal in other parts to compensate, so the outer arc The wall thickness is about 10% thinner. However, due to the characteristics of single-piece production and low cost, the stamping elbow process is mostly used in the manufacture of small batches and thick-walled elbows.
