Will scratches on a casting film roller affect product quality?
If scratches exist on the surface of the casting film roller: • The material fills these tiny grooves. • After cooling, corresponding surface defects are formed. This is why scratches on the casting film roller directly affect the appearance quality of the product.

Why does film sticking occur on casting film rollers?
Temperature is one of the most critical factors. When the surface temperature of the cast film roller is too high, the following will occur: • The film separates from the roller before it has cooled sufficiently. • The surface remains viscous. • Adhesion to the roller surface.

Casting Film Roller vs. Cooling Roller: What's the Difference?
Cast film rollers are the core rollers that directly participate in material forming and determine product quality, while cooling rollers are mainly used to reduce material temperature and assist in stabilizing the process.

Why Must Industrial Casting Film Rollers Ensure High Surface Finish?
• The smoother the roller surface, the smoother the film surface • Microscopic defects on the roller surface will also result in corresponding defects on the film surface Therefore, the surface condition of the cast film roller is not an "indirect influence," but one of the core factors directly determining the surface quality of the film.
