Roller, mirror roller, in particular, with respect to its for plastic packaging industry's not ready to see, it is also an indispensable key components, either for calender and its extrusion, for its cast, moreover, including its forming terms, we would actually is also noticed that it actually is also inseparable from the roller.

In terms of the surface precision quality of roller manufacturing and the reasonable structure of its internal flow channel and the quality of processing precision, in this respect, it will directly affect the quality of plastic products to a certain extent, especially for plastic film is actually because of this. No matter what kind of process is adopted, the structure, design, material selection and manufacturing of the equipment should meet a series of requirements.

It is important to note that the roller should be sufficiently rigid, and then, in terms of its bending deformation, it should not exceed its allowable value in terms of ensuring a heavy load. Furthermore, the surface should be of sufficient hardness, and then, we should pay attention to the requirements of HRC50 degrees above, it is actually a relatively strong corrosion resistance.

In terms of roller coating, it is actually will have a better ability to resist peeling, in this regard, in fact, to a certain extent to ensure that the work surface of the roller has a better wear resistance and corrosion resistance.

In fact, the working surface of the roller should be fine machining, so to speak, in fact, it can ensure the size accuracy of the roller and its own surface roughness. As for its roughness, it should be above Ra0.16, and there should be no stoma or groove. The wall thickness on the working surface of the roller is to be even, otherwise it will affect the quality of the products.
