The use and maintenance of the cast film machine?

In the extrusion belt casting, the plastic pellets are plasticized by a screw, and then extruded in a linear state through the die of a flat die. After stretching, the plastic particles are attached to the surface of flexible substrates such as paper, film, non-woven or woven cloth. Finally, the cast film machine, after cooling and forming for a period of time, compresses the composite material with the characteristics of the film layer. This composite material is barrier and heat sealable. The main purpose of the cast film machine is to apply to the film coating of laser printing, inkjet printing photo and other coated paper, tape, etc. The oil-based coating machine has more unique advantages than the water-based coating machine, which can make the finished product have better water resistance, sun protection and abrasion resistance, because the main features of the oil-based coating film are waterproof, moisture-proof and UV-proof, and it can also be repeated Coating, cost saving.
How to maintain the cast film machine in daily use
Cast film machine, also known as extrusion casting compound machine, is mainly an extrusion molding machine with a high degree of automation, simple operation and fast production speed. It has been used as early as in the United States and Europe, and has developed quite maturely in the United States and Europe. In recent years, it has been gradually applied in China. Coaters have gradually replaced dry mix and hot melt coaters. In daily life, the coating machine should be used to maintain the coating machine to achieve the effect of long service life.
1. After use, carefully check whether the temperature control device of the cast film machine is in good condition, and control the heating temperature of each point within a certain range
2. Check whether the traction speed of the casting film machine is within the normal range, and control the film thickness. If necessary, adjust the film thickness evenly, and the bending diameter should be within the standard range
3. Check the purity of the raw materials, do not mix impurities, especially some iron, therefore, check with iron in time, control the ratio of raw materials, and mix evenly when using raw materials.
