What Should be Paid Attention to in the Correct Use and Maintenance of Plastic Granulator?

1. After the plastic granulator extrusion mold arrives, unpack and check that the packaging is intact: after unpacking, take out the packing list and unpack for inspection. Instruction manuals and other technical documents shall be assembled and checked according to the contents of the packing list to check the whole mold, accessories, special tools, etc.

2. Half of the technical standards and models of the extrusion die. The extrusion molding parts generally use corrosion-resistant materials such as stainless steel plates. The extrusion die is especially when the extrusion material is modified polyvinyl chloride. And tempered to above HRC24 to ensure a certain service life. There should be no defects such as bumps, scratches, burrs, attachments and rust. The working surface of dies, setting dies and their parts should be smooth. Abrupt changes in cross-section and stagnant areas should be avoided as much as possible. The die runner system should be smooth along the direction of melt flow. The loading and unloading repeatability error of the corresponding positions between the molds and the templates is not more than 0.03mm. The welding surfaces of the extrusion die head and the splicing should be well-closed, and there should be reliable positioning between the templates. The local gap shall not be greater than 0.02mm

In the general mode, the water and air system of the plastic granulator should not collide with each other. The water pipe joints of the extrusion die calibrating die, the refrigeration system and the vacuum system of the calibrating die should be normal and not leak. Vacuum pipe joints should have obvious marks and must not affect the connection of the pipeline.
