TPU Cast Film Extrusion Line,TPU Car Clothing Film Production Machine

1.Introduction of TPU cast film production machine

(1)TPU (Thermoplasticpolyurethanes), hot plasticity TPU elastomer, TPU film is on the basis of the TPU granular material, through the flow process made into film. Gwell machinery TPU film production line has been combined with the group's years of equipment manufacturing experience, and at the same time learned from the production experience of many polyurethane TPU manufacturers, to adapt to the market continuous improvement, innovation and gradually reach the industry position. The equipment produces TPU with a width of 1372-1520mm and a thickness of 0.02-3.0mm. One or more single screw extruders can be used for co-extrusion. Each extruder is divided into 8 temperature control zones for accurate temperature control. Maximum output up to 600KG/H, single-layer, A/B/A or A/B distribution mode. It can meet the upper and lower two layers at the same time covered from the membrane, attached cloth. By adopting PLC overall control, only one person can easily control. Key parts disassembly and replacement is convenient, user-friendly. Reserved remote control port can be global remote to achieve synchronous monitoring, which is high cost performance. Products with high transparency, less crystal point, no air bubble. 

(2) In the TPU cast film extrusion line manufactured by Gwell Machinery, the side of the main body of this equipment is equipped with a dehumidifying and drying system and an electrical control system. A vacuum automatic feeder is fixed on the top of the dryer, a single screw extruder is installed on the side of the dryer, and a hydraulic filter is installed on the top of the single screw extruder. The screen changer and the melting pump adopt a through connection, and then connect with the mold through a flow channel. A casting machine is placed at the bottom of the mold. After the casting, there is a five-roller cooling part, and the five-roller cooling is followed by a thickness gauge for thickness measurement. Some auxiliary devices are added after the thickness gauge according to customer requirements, such as corona device and coating. cloth device and so on, and finally the winder.

(3) Due to the high density, elasticity, and high temperature characteristics of TPU granular resin after drying, the resin is easy to be stuck in ordinary hopper instead of entering into the extruder port, so special design of the hopper and barrel discharge opening is required. The TPU cast film extrusion production line has adjustable processing power, and the raw materials are extruded three times to make the finished product uniform in specifications.

2.Introduction and use of TPU cast film

TPU film not only has excellent tension, toughness and aging resistance, and is a mature environmental protection material. At present, TPU has been widely used in: shoes, clothing, inflatable toys, water and underwater sports equipment, medical equipment, fitness equipment, car chair materials, umbrellas, leather cases, bags, car clothes coated. Water-proof and moisture-permeable TPU film is used with various fabrics to achieve water-proof and moisture-permeable effect.

1. Introduction of TPU Hot Melt Adhesive Film

TPU hot melt adhesive film inherits the environmental protection of hot melt adhesive, wide bonding range, fast bonding, etc. It is widely used in textile fabric bonding, leather product bonding, plastic product bonding, foam product bonding, and metal composite board bonding, bonding in the electronic field. GWELL has developed a TPU film composite production equipment. This equipment can realize the production of TPU hot melt adhesive film and the composite of textile fabrics, leather and other products at the same time. Improve the quality and production efficiency of composite products.

2. Introduction of TPU film composite production equipment 

(1) TPU film compound production equipment is also called extrusion compound machine, casting machine, extrusion casting machine, casting compound machine. Our machine has the advantages of high degree of automation, easy operation, high production speed, uniform coating thickness, high adhesion fastness, smooth coiling, environmental protection and pollution-free, saving labor and raw material costs, etc. It has matured in Europe and America, and gradually developed in China. The application is an inevitable trend to replace dry laminating and hot melt adhesive coating laminating.

(2) The TPU composite extrusion production equipment is using extrusion casting molding method: plastic particles are plasticized by a screw and then extruded linearly from a flat die, and then attached to paper, film, non-woven fabric, or woven which are flexible substrates after stretching. After cooled, shaped and pressed into a composite material The TPU composite film now is combined with the barrier properties and heat sealability of the plastic film layer, the strength and toughness of the substrate, and the functional characteristics. At present, this production line can realize one machine with dual purposes, that is, it can be made of pure TPU film, or it can be used as a TPU film composite substrate, which can achieve high-speed coating composite, which can reach 100m/min.
