How do you clean an extruder die?

The production materials of film blowing machines are mainly PE, with varying colors, including transparent and solid colors. Many companies also use color powder as pigments for processing, while there are many large film blowing machines.

When changing colors, it is difficult to clean the screws and die heads, and the main difficulties are two points:

1. It is very difficult to clean sutures (also known as bonding threads)

2. Color mixing problem.

So how should a large film blowing machine clean the screws and die heads when changing materials and colors?

The main reasons for these problems are:

1.During the process of material plasticization and flow, when the material has not been completely replaced, it will generate binding lines of one color after another due to differences in gravity, velocity, and location;

2. When changing materials, if the two materials do not blend or have different melting indices, there may be color mixing problems. The fully biodegradable bag making machine

In response to this situation, it is recommended to use a special color changing and material changing cleaning material for the film blowing machine, utilizing the active ingredients in the material to exert its cleaning effect at a certain temperature, achieving a thorough cleaning effect without damaging the screw and die head.
