Plastic blown film machines play a crucial role in the packaging industry, producing plastic films that are widely used in various fields and bringing convenience to our lives. With the continuous advancement of technology, we believe that plastic film blowing machines will become more intelligent and efficient, contributing greater strength to the development of the packaging industry.

In practical applications, the maintenance of plastic film blowing machines is very important, which can extend the service life of the equipment and ensure production quality. Operators should regularly check the lubrication condition of the equipment, whether the connections of electrical components are good, whether the heating system is normal, etc., and promptly clean the inside of the machine and the mold head to ensure the normal operation of the equipment.

Material selection skills for Dalian plastic blown film machine

Firstly, the selection of materials for the main components of the equipment. For plastic film blowing machines, the main components include extruders, die heads, cooling rollers, and other parts. The material selection of these components should take into account their wear resistance, corrosion resistance, thermal conductivity, and other properties. Common materials include stainless steel, carbon steel, aluminum alloy, etc. Extruder components are generally made of wear-resistant and corrosion-resistant stainless steel materials; The mold head components should be made of materials that are wear-resistant and have good thermal conductivity; The cooling roller components should be made of materials with good thermal conductivity.

Secondly, when selecting materials, the impact of the production environment should be fully considered. Plastic film blowing machines are affected by environmental factors such as humidity, temperature, and air pressure during the production process. In order to ensure the normal operation of the equipment and extend its service life, the selection of materials should consider the impact of these factors on the materials. For example, equipment working in humid environments can use stainless steel materials that are rust proof and corrosion-resistant.

Once again, it is necessary to consider the physical property requirements for producing thin films. Different types of plastic films also have different material requirements. For example, LDPE (low-density polyethylene) has high requirements for material wear resistance and flexibility; HDPE (high-density polyethylene) requires high tensile strength and temperature resistance of the material. When selecting materials, it is necessary to choose according to the specific production requirements to ensure the quality of the film.

The selection of materials should be based on the production capacity of the equipment. The width and thickness of the film produced by different specifications and models of plastic blown film machines are different, so the selection of materials should be based on the production capacity of the equipment. For example, equipment with larger film widths should choose more wear-resistant materials to ensure stable operation of the equipment.

The advantages of plastic film blowing machines are high production efficiency, low cost, and simple operation. By adjusting parameters such as extrusion speed and stretching speed, films of different thicknesses and colors can be produced to meet the needs of different customers. Meanwhile, plastic film has excellent properties such as water resistance, gas resistance, gas transparency, and wear resistance, making it suitable for use in various packaging fields.

The plastic blown film machine is mainly composed of components such as extruder, die head, forming roller, cooling roller, and coiling machine. The extruder is the core component of a plastic blown film machine, which melts plastic particles through heating and extrusion, transports them to the die, and then extrudes them through the die's extrusion port to form a thin film. Forming rollers and cooling rollers are used to cool and flatten the film, ensuring consistent flatness and thickness of the film. The coiler is used to roll the produced film into rolls or roll it into bags.
