1. After the delivery of the extrusion die of the plastic granulator, the unpacking inspection and the turnover materials are intact: take down the packing list after unpacking, and open the box for inspection. Use manuals and other technical documents, and check the entire module, accessories, common tools, etc. according to the contents of the packing list.

2. Half of the standard specifications and methods of the extrusion die. The extrusion processing parts are generally made of corrosion-resistant materials such as stainless steel plates. The extrusion die is especially used when the extrusion raw material is modified material polyethylene. And heat treatment to above HRC24 to ensure a certain period of use. There should be no shortcomings such as knocks, scratches, burrs, appendages and rust. The working surface of the die mouth, the shaping die and the parts should be smooth and clean. Try to prevent gene mutations and stagnant areas in the cross section. The die runner system software should be gentle along the direction of melt fluidity. The loading, unloading and handling repeatability error of the relative parts between the molds between the molds is not more than 0.03mm. The welding surface and splicing of the extrusion mold die must have excellent airtightness, and there should be reliable and accurate positioning between the molds. Part of the gap should not exceed 0.02mm

In general, the water vapor system software of the plastic granulator cannot collude with each other. The water pipe quick connector of the extrusion die, the refrigerating unit and the ultrafiltration device of the shaping die should be the same one that does not leak. The connection head of the vacuum solenoid valve should be marked clearly, and it should not harm the connection of the pipeline.
