TPU cast film production line
TPU cast film production line manufacturing technology, including feed, extruder, melt line (including filtration), die, casting, traction, unwinding, winding, etc., TPU cast film production line, TPU Casting machine, TPU film and bonding production line, TPU film production line, TPU film equipment, TPU shoe material, TPU clothing material, TPU luggage material, TPU air expansion material composite unit TPU film production process (casting) main control focus can be divided For several aspects:
First, the selection of TPU materials. There are many kinds of TPU materials, such as Japanese materials, Taiwan materials, Bayer, and BASF. According to user needs and actual production, choose the right one.
Second, granulation and baking before production. The process of granulation and baking before production should also be paid attention to, which can reduce the occurrence of problems such as foaming and impurities during the production process.
Third, the control of temperature and production speed during the production process. Temperatures include die temperature and pinch temperature. The production speed should pay attention to the extrusion speed and winding speed of the die material.
TPU cast film production line equipment features: compact equipment, superior performance, screw and barrel optimized design, the machine has the advantages of uniform plasticization, stable extrusion, high output and long life. Reasonable material quantity configuration makes the whole machine small in power and consumes less energy. The hydraulic system is designed to be more reliable and quicker. All electrical boxes are fixed to the rack for easier transportation and installation, easier wiring and fewer failures. The extruder is made of special high temperature corrosion resistant steel. For the particularity of the material, the TPU cast film production line is specially designed for the structure of the screw, the die structure and the special shaped T-die are designed with special double-throttle design. The film thickness is high and the speed is more accurate. The screw adopts special mixing function and high plasticizing capacity design, which makes the pellets melt and the uniform color extrusion increases. The temperature control adopts advanced automatic control system, which can accurately control the plasticizing process, adjust the film thickness and flatness. The heat-sealability of the extruded cast film is good when it is heated, and it is favorable for heat-sealing the bag. Our machines can produce high quality membranes with low cost, high productivity, stable operation, uniform film, low waste, and low energy assumptions.
The combination of TPU (polyurethane elastomer) film and TPU film and substrate is a new environmentally friendly plastic product newly introduced in the international market in recent years. Due to its superior performance and environmental protection concept (material buried in the soil, affected by environmental temperature and microbes, and automatically degraded within 3-5 years), it is increasingly used in various industries and daily necessities. The market prospect is very broad and there is a huge market. Application potential.

What is a TPU cast film?
TPU film is a film product made of TPU material as the main raw material. It is a new type of high performance environmentally friendly film material with high strength, good toughness, cold resistance, oil resistance, aging resistance, weather resistance, environmental protection, non-toxicity, decomposability, etc. Excellent characteristics. Due to its easy to use and diversified functions, TPU film has been rapidly developed in recent years, and is used in shoe materials, waterproof and moisture permeable clothing fabrics, food packaging, medical supplies, inflatable capsules, weapon packaging, tents, sports and leisure equipment, Wide range and unique applications in many fields such as toys and consumer daily necessities packaging
What is the use of TPU cast film?
Thin film TPU is increasingly popular due to its superior performance and environmental protection concept. At present, wherever PVC is used, TPU can be a substitute for PVC. TPU film can be used not only to bond with various fabrics, but also to produce a clear and dimensionally stable product by vacuum thermoforming. With the continuous improvement of domestic environmental awareness, the application of TPU has become more and more extensive. Among them, the areas with faster speed increase: upper lining, thermal underwear, transparent underwear, transparent shoulder strap, elastic band and medical breathable tape.
