To bear the bulging force of the billet, there are high requirements for structural strength, stiffness, surface hardness, surface roughness and machining accuracy. The development level of mold production is one of the important signs of mechanical manufacturing level; there are many types of molds, according to the processing objects and The processing technology can be divided into: metal processing molds and non-metallic and powder metallurgy molds; including plastic molds (such as injection molds, compression molds and extrusion molds, etc.), rubber molds and powder metallurgy molds; according to structural characteristics, The mold can be divided into a flat blanking mold and a cavity mold with space; the mold is generally a single piece and produced in small batches; in addition to the mold itself, it also needs a mold base, a mold base, and a mold core to cause the ejection device etc. These parts are generally made of general purpose; mold companies need to be bigger and more refined, and determine product positioning and market positioning according to market demand, technology, capital, equipment and other conditions. These practices are especially worth learning and learning from small mold companies , Concentrate on gradually forming their own technological advantages and product advantages; therefore, China's mold companies must actively strive to learn from the experience of these advanced foreign companies in order to better develop in the future.

Short tubes are generally formed by stamping with a forming die. If the tube is too short, the punched out mouth will be easily deformed, and air seams will appear after welding, requiring re-welding. The production efficiency is very low, and the labor intensity of the workers is high due to frequent rework.
