Plastic Rollers And Stainless Steel Control Requirements
Plastic Rollers and stainless steel tubes in particular, the mirror roller for the plastic packaging industry equipment is an indispensable component, whether it is calendering, extrusion or the flow of the forming of the stainless steel tube and Plastic Rollers. The impact of the quality of plastic products is good and bad mainly: stainless steel tubes and Plastic Rollers to make surface precision quality and internal flow duct structure of reasonable and processing accuracy of good and bad, especially the production of plastic film. Therefore, it is important to provide a high-quality stainless steel tube and roller for plastic film products manufacturers.
The stainless steel tube and the roller type are numerous, and each has its own unique role, according to the process of rolling down the stick, pressure singles, rolling roll, etc., according to functional use of the heating roller, cooling roller, lead off roller, roller, etc., according to the structure of the seamless steel tube roll, forging and centrifugal casting roller and so on. In short, the different processes of plastic products require different stainless steel tubes and Plastic Plastic Rollers, therefore, as a stainless steel tube and drum manufacturers in the process of undertaking stainless steel tubes and Plastic Plastic Rollers, should be aimed at different products, different process design and manufacture of the corresponding stainless steel pipe and roller, in order to ensure that the stainless steel pipe and drum in the production process to play its normal role. No matter what process, the structure, design, material selection and manufacturing of stainless steel tubes and Plastic Rollers shall meet the following basic requirements:
1, stainless steel tubes and Plastic Plastic Rollers should have enough rigidity to ensure that under heavy load, bending deformation does not exceed the allowable value.
2, the stainless steel tube and the roller surface should have enough hardness, the general request achieves the HRC50 degree above, has the strong corrosion resistance. The coating has the ability to resist spalling, to ensure that the stainless steel pipe and drum working surface has good wear resistance and corrosion resistance.
3, stainless steel pipe and drum working surface should be fine processing, to ensure the size of precision and surface roughness. Roughness should be Ra0.16 above, can not vent or groove. Stainless steel pipe and drum working surface thickness to be uniform, otherwise it will make the roller surface temperature uneven, affecting product quality.
4, stainless steel pipe and roller materials should have a good thermal conductivity, generally used chilled cast iron, special cases using cast steel or molybdenum-chromium alloy steel, whether it is heating or cooling, can achieve rapid uniformity.
5, stainless steel pipe and drum design to facilitate processing, product cost to be low, production quality and process to be strict, to achieve both cost savings, but also to increase the benefits.
