Plastic Sheet,plate and film chill roller

This product is widely used in master casting forming of BOPP, BOPET, BOPA, BOPS, BOPI biaxial oriented stretching line and longitudinal stretching line. Special inner circulation channle is designed to improve the heat conversion efficiency and temperature control accuracy. After replacing with this kind of technically updated roller, the casting effeciency will rise by 20%-30%.

Casting system is a step of of vital importance in film stretching line. The finish film quality after stretching will be finally based on master precsion of casting system. This casting roller manufactured by Suzhou Jwell Precision Machinery Co.,LTD has already been used a lot in high level stretching line imported from Europe and its performance in practical application obtains unanimous approval and favorable comment from customers.

1)Material:We adopt 45# seamless steel pipe, alloy steel, precision forgings or rolled round 45# steel pipe

a. Mirror rollers are generally made of 45# steel, alloy steel seamless tubes, precision forgings and other materials, and the surface finish of the roller can reach Ra0.01 (level 14);

b. The roller blank is made of professional imported alloy steel, and different flow channel structure forms are designed according to different material characteristics;

c. Mirror processing can be performed on the surface of various materials to ensure that the straightness, balance, non-roundness and coaxiality of the roller surface meet the requirements;

2)Sand blasting process: It can improve the fatigue resistance of the workpiece, increase the adhesion between it and the coating, extend the durability of the coating film, and also help the leveling and decoration of the coating, and remove impurities, variegation and oxide layer on the surface At the same time, the surface of the medium is roughened, the residual stress on the substrate surface and the effect of increasing the hardness of the substrate surface. The etching process is a chemical surface treatment method, which sometimes will affect the appearance of the finished product.

3)Quality:Usually chromium is critical for mirror roll products. Our surface requirements for mirror roller is usually determined by the thickness and hardness of the chromium layer.While these are determined by many years of experience in the surface processing of rollers. According to the analysis, if the quality of the surface chromium layer is not hard enough, its surface will have a substantial impact on the production of sheet products such as PC, PP, PMMA, PET, etc., and this is an important factor that causes the durability of the roller.
