Cleaning method of film blowing machine die head

Clean the touch head and spiral body. When cleaning, apply paraffin wax or methyl silicone oil, and then gently wipe the paste with 1000-grit sandpaper until it is clean. When changing the material, adjust the temperature appropriately according to the material properties (the temperature of the returned material is different from that of the pure material). After changing the screen, increase the extrusion volume to extrude the paste.

The key is that during the production process, it is often best to add a little methyl silicone oil to the hopper once a week, which can not only lubricate the screw die, but also play a role in cleaning the mold.
