Film Extrusion Line
We have own experimental institution and professional company to research and develop high-performance plastic film extrusion machines. The main film production lines include EVA, POE photovoltaic film extrusion line, PVB, SGP glass interlayer film extrusion line, TPU film extrusion line, PE breathable film extrusion line, cast film extrusion line, stretch film and medical film extrusion line. Based on the proven JWELL extrusion technology, the core processing components(screw, barrel, mold, machine frame, metal heating treatment and other spare parts) have been newly designed and produced by our own professional factory. Our screw&barrel manufacturing company has been founded in 1978, and produced the first high-quality screw in China at that time, also has been the famous and reliable brand in the market.
What Are the Production Technologies of Plastic Film?
The complete film extrusion production process includes: mixing raw materials and additives, feeding, single screw plasticization, change screen, extrusion, roller forming, cooling, traction and cutting. We choose famous roller and special designed screw for precise production.
What is the Difference Between Blown Film and Cast Film?
The film blowing process is mainly divided into two forms: upper blowing cooling and lower blowing cooling. In terms of appearance, the cylindrical film is the main performance feature, and the tensile strength is better than that of the cast film. The casting method is mainly composed of multiple extruders, multiple channel distributors, T-die, casting system, horizontal traction system, oscillator and winding system. The main characteristics are that the produced film products have good surface gloss, high flatness, small thickness tolerance, good mechanical elongation, good flexibility, and higher transparency than blow molding.
How Do You Improve Plastic Film Production?
As we all know that uniform film thickness and smooth surface are very important for good quality film. Before production, we need to choose good extrusion machine firstly, including special screw structure, precise temperature control system, high quality rollers and experienced technology. If you need these help, please contact us at any time.
