Clean the die head and spiral body.When cleaning,apply paraffin or methyl silicone oil,and then gently wipe the paste with 1000 mesh sandpaper until it is clean.During refueling,the temperature shall be adjusted appropriately according to the material properties (the temperature of return material and pure material shall be different).After changing the screen,increase the extrusion amount and extrude the paste.
The key is that it is often best to add a little methyl silicone oil to the hopper once a week in the production process,which can not only lubricate the screw die head,but also play the role of mold cleaning.
