Jinming Machinery (Guangdong) Co., Ltd.

This 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 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 450mm die is up to 810kg/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 and high efficiency.

Improvement of product quality
Different from the process in which the film bubble is blown up after being out of the die, the film bubble will not be blown up until it is pre-cooled. High polymer materials if stretched in quasi-viscous flow state will have a lower degree of crystallization, and thus the film transparency and mechanical properties will be greatly improved.

High cost performance
Compared with traditional air rings, the next-generation high-efficient multi-outlet air ring increases production capacity by 40-50% but the manufacturing cost increases by only 40%. The newly-increased cost will be recovered by the electricity expenses saved in six months.

Since screws and die head of the MBL line are specially designed for processing gas barrier resins such as PA and EVOH, this line is mainly used for producing various specifications of five or more layers film which can meet the demands for gas barrier (O2, N2, CO2…) for the purpose of refreshment, preservation, sealing and shelf life extension.

The whole line is designed in a modular idea that is making it easier for processing different resins, formulas and new products.

Precise layer ratio control system makes it possible to save expensive resin while ensuring the barrier function.

Auto gauge control system equips with closed-loop control system consisting of inline thickness measurement and automatic die head (automatic air ring) for automatic detection of film thickness and control.

The centralized computer control system controls the temperature, rotating speed, pressure, wind speed, haul-off speed, tension and line speed with the digital communication network, displaying and monitoring temperature, pressure, current, voltage, tension, speed, film length and other parameters. The system also has functions of automatic alarms and can run a self-diagnosis routine.

The line adopts the world advanced high-tech patent technology to produce both symmetrical and asymmetrical barrier films with excellent performance such as outstanding formability and high barrier performance. With more than 3 barrier layers, the film products are widely used in packaging of food, farming products, petrochemical and medical products.

Automatic die head, double water cooling ring, sizing water ring and oscillating haul-off system can be applied to meet different requirement and formula.

The POF line represents the improved design of dual-bubble forming heat-shrinkable blown film technology. The system features an advanced central feeding spiral die head and internal bubble cooling system, infrared radiant heaters and temperature measurement module, tension control system and double-station automatic contact/central/gap rotating winder.

The line excels at producing POF shrinkable film with PP/PE/PE/PE/PP structure has excellent properties, such as high transparency, low temperature resistance, twisting resistance and a high shrink ratio. They are ideal and environmentally friendly heat-shrinkable packaging film which is widely used for food, beverage, medicine, cosmetic, commodity, stationary, magazine, video tape, electrical components and machines.

Jinming has begun to enter the development and production of cast film machine from 2002, and has been devoted to high-performance, high-quality and low-power machines. The CPP/CPE extrusion system adopts special screw design with good corrosion resistance, wear resistance, and has advantages of high yield, low energy consumption, and good plasticizing effect.

The barrel heating uses rust aluminum heating. The remaining core components are made of imported products to ensure quality. Unique T-die design technology and fluid simulation, ensure the melt inside the die head has uniform layer and consistent extrusion speed; The screw has separation, barrier, mixing, and other functions and it is specially hardening treated, with high yield, low energy consumption and low-temperature plastics; The machine has high degree of automation and large production; compared to the other products of same series, it increases the production capacity by more than 30%.

Jinming is the first enterprise in the Asia Pacific region that is able to produce 11-layer high barrier cast film line. This line is perfectly adapted to various raw materials, with high production capacity, representing the most advanced manufacturing technology.

With strong adaptability, the equipment can be well adapted to different grades of PE, PP, PA, EVOH according to the customers' needs. The core components of the equipment adopt internationally renowned brands, and the key components are designed and made by Jinming.

This Machine uses advanced processing technology to ensure the drawing ratio reach 10 times and perfectly adapted to various raw materials such as PET, PP, PE, PVC, EVOH and etc.
