Description

China GWELL TPU film extrusion line Introduction

TPU film extrusion line, which belongs to TPU film production equipment, solves the problems of poor plasticizing effect, low output and single suitable raw material of existing plastic extruder limited by extrusion screw structure.
By adding a barrier part on the homogenizing section of the extrusion screw, the barrier part and the homogenizing part are arranged alternately with each other, so that the material can pass through the homogenizing part and the barrier part alternately during plasticizing extrusion, so as to improve the plasticizing effect, thereby increasing the extrusion output.

TPU (thermoplastic polyurethanes), a thermoplastic polyurethane elastomer, is a film made by extrusion casting process on the basis of TPU granular material. TPU adhesive film not only has excellent tension, tension, toughness and aging resistance but also is a mature environmental protection material.

At present, where PVC is used, TPU can become a substitute for PVC. The advantages of TPU are beyond the reach of PVC.
As a new environmental protection material, TPU has made a major breakthrough in the application of waterproof and breathable fabrics, overcome many defects of PVC and PU leather, and has excellent comprehensive physical and chemical properties. It is known as the material of the future.

Combined with the equipment manufacturing experience of the group and years of production experience of TPU manufacturers, Gwell extruders, single-layer, A/B/A or A/B distribution films can be produced, and the output can reach 600kg/h.

The TPU film extrusion line and  PETG film extrusion line cover both release film and patch. As a China Plastic Extruder manufacturer, GWELL adopts PLC control for the whole line, which can be easily controlled by one person. The disassembly and replacement of key components is convenient and user-friendly. The remote control port is reserved for simultaneous monitoring around the world.

TPU laminating extrusion line

TPU film extrusion line can customize the production line according to customer needs, including TPU laminating extrusion line.

Summary

TPU laminating extrusion line uses TPU granules as raw material to produce TPU film by extruder extrusion; or directly coated on the substrate, TPU transparent film production line makes TPU composite film.

GWELL TPU laminating extrusion line belongs to the technical field of TPU film production equipment. It solves the problems of poor plasticizing effect, low output, and single applicable raw material of existing plastic extruders limited by extrusion screw structure.

By adding a barrier part on the homogenizing section of the extrusion screw, the barrier part and the homogenizing part are arranged alternately so that the material can pass through the homogenizing part and the barrier part alternately during plasticizing extrusion, improving the plasticizing effect, thereby improving the extrusion output; in addition, the compression ratio of the extrusion screw reaches 1.5~4.0 and can adapt to the plasticizing extrusion of various raw materials such as TPU hot-melt adhesive.

TPU laminating extrusion line process includes: using an extruder to extrude TPU material, then through coating technology, TPU is coated on a silk thread or cotton thread to get TPU composite material, which can be wound into thread roll or directly made into a textile. By weaving the fiber layer and the TPU material together, a TPU composite material with good air permeability and high mechanical strength is prepared.

TPU laminating extrusion line is a composite material formed by compounding TPU film on various fabrics, combining the characteristics of the two to obtain a new type of fabric, which is used in various online composite types such as clothing and shoe materials, sports fitness equipment, and inflatable toys. Material.

TPU laminating extrusion line adopts a one-step casting compounding method, the production line has a high-speed automation function, realizes single-sided or double-sided online compounding molding method, replaces the traditional offline secondary and tertiary compounding forms, reduces product production operations, and greatly reduces The production cost and production efficiency are improved, and the composite strength and product quality are also improved.

Features of TPU laminating extrusion line: Through the co-extrusion of 2 or 3 extruders, TPU raw materials with different temperature ranges and hardness ranges are compounded and extruded at one time. Compared with the traditional composite process, it is more economical, more environmentally friendly, and more efficient to combine the high-temperature and low-temperature films off the assembly line.

TPU laminating extrusion line products are widely used in water stops, shoe materials, clothing, luggage, stationery, sporting goods, and so on.

 

Points to note in the processing of TPU film extrusion line

TPU melts are sensitive to shear and temperature. Too high shear will lead to poor product performance, and too high temperatures will lead to melting decomposition, so there are certain requirements for TPU film extrusion lines and screw design.
Generally, the processing temperature and shear rate of the TPU film extrusion line are controlled by reducing the speed of the screw, but this will lead to a decrease in extrusion volume. Therefore, it is recommended to use a barrier-type forced feed screw with a smooth barrel to solve the extrusion volume problem.

TPU film has good tensile elasticity, so we must pay attention to the traction and winding process, generally in the traction process to maintain the stability of the tension and reduce the traction force as much as possible, so some equipment adopts tension closed-loop control method to achieve the constant tension of traction, ensure the stability of the tension, and wind through the gap winding method.

Production process of TPU car paint protection film extrusion line

In the production of invisible car covers, the most important part is the extrusion film. This step is to compound the coating and adhesive layer with the TPU original film through a special process.

TPU particles need to go through a complex process to be converted into TPU original film, and the quality of the original film also varies with the process, and GWELL’s TPU car paint protection film extrusion line is one of the few mature equipments.

The quality of the TPU film is relatively good, with high gloss and good stability, which itself can make the invisible car cover have good quality, so many high-end brands will choose it.

The TPU car paint protection film extrusion line produces TPU with a width of 1372mm-1520mm and a thickness of 0.02-3.0mm. It can be co-extruded with one or more single-screw extruders, and each extruder is divided into 8 temperature control zones. The maximum output can reach 600KG/H, and it can be used as a single-layer, A/B/A or A/B distribution.

The equipment can meet the requirements of covering the release film and cloth with the upper and lower layers at the same time and adopts PLC overall control, which can be easily controlled by only one person. Synchronous monitoring is very cost-effective. The product has high transparency, few crystallization points, and no bubbles when entangled.
