What is the role of the casting machine?

The main function of the casting machine screen changer in the cast film extrusion process is to eliminate impurities in the melt and improve the physical and chemical properties of the cast film. So what is the role of the casting machine?

What is the role of the casting machine?

1. The melt is divided and reorganized, and further plasticized and mixed to improve the dispersion and uniformity of the blend system.

2. Establish a suitable melt pressure, remove the gas in the material, increase the density of the melt, and prevent the diaphragm from breaking holes and pores.

3. Performance requirements of screen changer in cast film production: cast film products have many functions, high requirements and strict processing conditions. Only an excellent screen changer can meet the requirements of cast film production. The specific requirements of the cast film screen changer are as follows:

What are the advantages of the casting machine?

1. Fine filtration, no impurities escape.

2. The flow channel of the screen changer has no stagnation area, no dead angle and no material overheating degradation.

3. When replacing the filter screen, the material flow is stable and the temperature fluctuation is small, which can ensure the continuous production of the product for a long time without waste and defective products.

The filter is cheap and will not produce secondary cross-contamination after one use.

5. Network switching operation is simple and easy, saving labor and effort.

6. High temperature resistance, high pressure resistance, no leakage.

7. The network converter has stable performance, reliable operation and low application cost.

How should the casting machine be maintained?

1. Casting machine, also known as squeeze casting compound machine, is a high degree of automation, simple operation, fast production of extrusion molding machine. It was first used in the United States and Europe, where it developed quite well. In recent years, it has been gradually applied in China. The coating machine has gradually replaced the dry mixed hot melt adhesive coating machine. In daily life, the coating machine should be used to maintain the coating machine to achieve the effect of long service life.

2. This composite material has barrier and heat sealing properties. The main purpose of the casting machine is suitable for film coating of coated paper, tape, etc. Such as laser printing and inkjet printing photos. Oily coating machine has more unique advantages than water-based coating machine, which can make the finished product 3. Water resistance, sunscreen, and abrasion resistance better, because the main features of oil-based coatings are waterproof, moisture-proof, and UV-proof, and can be repeated Coating, saving costs.

4. After use, carefully check whether the temperature control device of the casting machine is in good condition, and control the heating temperature of each point within a certain range. Check whether the pulling speed of the casting machine is within the normal range and control the film thickness. If necessary, the film thickness should be adjusted evenly, and the bending diameter should meet the standard range. Check the purity of the raw materials and do not dope with impurities, especially some iron. Therefore, it is necessary to check with iron in time, control the proportion of raw materials, and mix evenly when using raw materials.
