Single Roller Assemble (SRA) Corona Treater Machine – Advanced Surface Treatment System
The Single Roller Assemble (SRA) Corona Treater Machine by ElectroTech Industries is a high-performance corona treatment system designed to enhance the surface energy of plastic films and sheets. This industrial corona treater ensures superior ink adhesion, coating performance, and print quality, making it an essential solution for modern printing and packaging industries.
Engineered with precision and reliability, the SRA model is ideal for inline integration in extrusion, coating, and converting lines, delivering consistent and efficient surface activation for a wide range of plastic substrates.
Why Choose SRA Corona Treater Machine?
In high-speed production environments, untreated plastic surfaces often lead to poor ink bonding and coating failures. The SRA corona treater for plastic uses high frequency corona discharge to modify the surface at a molecular level, significantly increasing surface tension and improving wettability.
This results in:
Better adhesion of water-based, solvent-based, and UV inks
Enhanced coating and lamination performance
Reduced rejection rates and improved productivity
Single Roller Assembly
The web can be fed over the SRA in A ‘U’ shaped path, reversing its direction of travel, or through the SRA in a ‘Z’ configuration, maintaining the same direction of travel
It is insensitive to attitude and can even be mounted upside down.
Solidly supported on all four corners by nylaguide bearings, it is not subject to deflections caused by cantilever stresses.
Radial bearings are sealed, and linear bearings are self – cleaning and self – lubrication.
Standard adapter bases consists of a stationary floor mounted frame or plate, a four unit, standard nylaguide bearing and support system, and a moving frame of plate.
A heavy duty servo cylinder is nested between the frames and the nylaguide bearings.
The servo cylinder moves the upper adapter base plate back and forth in response to hydraulic signals from the power unit.
THE PRINCIPLE
The Single Roller Assembly with Web Guiding System is designed so that is swings in an arc laterally, pivoting about an imaginary pivot point located exactly in the plane of the entering web path.
High quality Single Roller Assembly with Web Guiding System
The servo cylinder swings the other end of the frame, moving the outgoing web laterally back into the desired web path.
It can be installed successfully on lines handling fragile materials such as parchment paper, thin metal foil, or saturated paper even.
