In blown film extrusion, scanners are devices that measure and control the thickness of the plastic film. These machines rotate or oscillate around the film bubble and check the thickness at each point.
Corona treatment is a surface modification technique used to enhance the surface energy of films produced through blown film extrusion.
An electric motor is a mechanical or electrical device that generates the rotational or linear force used to power a machine. Electrical motors are two types.
The drive system is a critical component of a blown film extrusion machine, acting as the driving force behind the whole process.
