Daily maintenance of cylinder

1. Do not start the machine until the feed barrel screw has reached the preset temperature.

2. Prevent metal fragments and sundries from falling into the hopper. If the material is processed and recycled, a magnetic hopper shall be added to prevent iron scraps from entering the barrel.

3. Make sure that the plastic in the feeding barrel is fully melted when salivation is used, so as to avoid damage to the transmission system parts when the screw goes back.

4. When using new plastics, clean the remaining materials of the cylinder.

5. When the temperature of molten plastic is normal, but black spots or discoloration of injection plastic products are constantly found, it is necessary to check whether there is wear of screw overgel head, overgel ring and over glue meson.

6. When the product is injection molded, make the material plasticize evenly as far as possible, so as to reduce the transmission torque borne by the screw and improve its service life.
