Roller, especially mirror roller, it is not prepared for the plastic packaging industry, in fact, is an indispensable important parts, no matter in calendering, extrusion or flow forming is also inseparable from the roller. The surface precision quality of roller making and the reasonable structure of its internal flow channel and the quality of machining precision directly affect the quality of plastic products to a certain extent.

Furthermore, we also is to actually pay attention to, for actually is also a greater diversity of roller, and another way, we also is to actually pay attention to itself, in fact I can have the effect of a series of unique, according to the technological process, is also a rolling stick, pressure bachelor, stretch film roll, etc., or is carried out in accordance with the function use to, also is to have a heating roller, cooling roller and its lead from the roller, roller, etc.

Next, for the roller itself, we actually need to pay attention to the structure itself which is divided into seamless steel roller, forging and its centrifugal casting roller. In a word, in terms of the different processes of plastic products, we should pay attention to that it needs different rollers.

In the case of the roller, when making and designing it, we should pay attention to the fact that it should have a sufficient rigidity, that is to say, make sure that its bending deformation cannot exceed the allowable value under heavy load. For the surface of the roller is to have enough hardness of clothes moth, in general, we will actually require it to reach HRC50 degrees or above.

Next, for the roller, we are to pay attention to its own in fact, is to have a strong corrosion resistance. For the coating itself, in fact, it should be an anti-spalling ability, in this way, that is to ensure that the roller working surface has a better wear resistance and corrosion resistance.
