The double-ring drum blow molding machine is specifically designed for producing double-layer or multi-layer plastic drums. The capacity range of the drums it produces varies depending on the model and specifications of the machine. Generally speaking, the double-ring drum blow molding machine can produce drums ranging from tens of liters to thousands of liters, with common capacities including 200 liters and 220 liters.
In terms of application areas, the double-ring drum blow molding machine has a wide range of applications. Due to the sturdy structure of double-ring drums, which can withstand heavy weights and pressures, they are typically used for containing heavier items such as chemicals and liquids. Therefore, this machine finds extensive use in industries such as chemicals, petroleum, pharmaceuticals, daily chemicals, food, and more. These industries have high requirements for packaging containers, demanding features like acid and alkali resistance, corrosion resistance, leak-proofness, colorfastness, and shape retention, which double-ring drums produced by this machine can effectively fulfill.
