Jinming Superex models are equipped with a new generation of high-efficiency cooling air rings

2014.12.04
As the earliest and largest film equipment manufacturer in China, Jinming Precision Machinery has always mastered the advanced manufacturing process of multi-layer co-extrusion film technology, and at the same time leads the domestic industry technological innovation. With the prosperity and development of the entire plastic packaging industry, customers' demand for high-end products and equipment has gradually increased. In this regard, Jinming Precision Machinery's high-end Superex series equipment has been designed from the beginning to meet the needs of customers for automation control and high performance. Its design concept and technical process have reached the world's leading level.

Superex series equipment has the characteristics of high automatic control and high production capacity. In addition to its processing technology, die head and runner design and other component factors, the new generation of high-efficiency multi-tuyere cooling air ring independently developed and produced by Jinming is the most important part of the equipment. A highlight, and one of the few thin-film equipment companies in the world that has mastered this technology. In the blown film forming process, the cooling of the air ring is a very important control link in the blown film process, which plays a very important role in determining the output, appearance quality and physical properties of the film.

In the process of improving the technology of film blowing equipment, the structure of the air ring has also been continuously improved from the traditional single air outlet air ring, double air outlet air ring, precision air ring to automatic air ring. The new generation of multi-vent high-efficiency cooling air ring developed by Jinming this time is characterized by more than 3 air outlets, the air volume of each air outlet can be adjusted according to the size of the process, and the air ring can be vertically lifted along the axis of the die head. Due to the multi-stage air outlet, the contact area between the film bubble and the air is large, the cooling time is long, and the efficiency is high. At the same time, the melt strength of the film bubble becomes stronger after pre-cooling, and the air volume of the upper tuyere can be increased without causing instability of the film bubble. .

The Superex series models equipped with a new generation of multi-vent high-efficiency air rings mainly include the following advantages:

Production increased significantly
The new generation of multi-vent high-efficiency cooling air ring developed by Jinming Precision Machinery is more than 40% higher than the double-air vent air ring (or automatic air ring) commonly used in China. On the premise that the extrusion volume can be guaranteed, Since the cooling effect is increased by 40%, the output of the whole line can be increased by 40% to 50%. It has been confirmed by reliable test data that the output of 300mm die can reach 420kg/h, and the production capacity is at the forefront of the industry.

Film physical properties are significantly improved
Because the film bubble is pre-cooled by the lower wind ring after it exits the mold before it is blown up, when the film bubble is blown up in the upper wind ring, the strength of the film bubble is already very high, and products with a higher blow-up ratio can be produced. This cooling process is similar to POF and HDPE anti-aircraft inflation.

Product accuracy control is more stable
In the upper air ring for controlling blowing and cooling, we can continue to adopt the automatic air ring air technology, and cooperate with the film online thickness measurement system to better realize the automatic film thickness control. Since the upper air outlet is far away from the high temperature die head, and the film bubble is pre-cooled, the control accuracy of the automatic air ring is significantly reduced by external interference factors. Good control stability and high efficiency.

Appearance quality of products is significantly improved
Change the process of blowing up the film due to the exit, the film bubble is blown up after pre-cooling, the polymer material is stretched and shaped in a semi-viscous flow state, the crystallinity will be lower, and the film transparency and mechanical properties will be significantly improved.

Great value for money
The manufacturing cost of the new-generation multi-vent high-efficiency air ring is only 40% higher than that of the traditional air ring, while the production capacity of the entire line is increased by 40% to 50%. Only from the electricity cost of increasing production capacity and reducing the cost of electricity, the new cost can be recovered in 6 months.
