Description

Superex Blown Film Machine uses advanced processing technology, dies and runners, and a next-generation high-efficiency multi-outlet cooling air ring independently developed and produced by Jinming Machinery to achieve high-degree automation and high productivity. The Superex equipment with the next-generation high-efficiency multi-outlet cooling air ring has the following features: Increase of output Jinming Machinery’s proprietary next-generation high-efficiency multi-outlet cooling air ring increases the cooling efficiency by more than 40% compared with common air rings (or automatic air rings) with double outlets in the China market. As a result, the output of the production line will increase by 40-50% when the extrusion capacity is ensured. Testing data show that the production capacity of a 300mm die is up to 420kg/h, which is ranked at the top in the industry. Improvement of physical properties of film After coming out of the die, the film bubble will first be pre-cooled at the lower air ring, and then blown up at the upper air ring so that the film bubble will have high strength and the products will have a high blown-up ratio. This cooling technique is similar to the POF and HDPE blow-up method. Steady product precision control Automatic air ring technology is used in the design of the upper air ring for blow-up cooling control and an online film thickness measuring system is used for automatic film thickness control. Because the upper air outlet is away from the high-temperature die and the film bubble is pre-cooled, the precision control of the automatic air ring is less affected by external factors to achieve good control stability
