Corona Treater

E Chip Control Systems is the leading Manufacturer,Supplier and Dealer of Corona Treater,Plasma Treater,Corona Discharge Equipment in Chennai,India

E Chip Control Systems is capable of providing solutions for any kind of corona treating problem for plastic films, different varieties of complex laminates and metalized films. We produce corona treatment equipment  in the range of 1 kw to 10 kw for web widths of 3000 mm.

E Chip Control Systems  have installed many  corona treatment machine on extrusion coating plant ,where paper has to be treated before coating for better bonding. We have installed many corona discharge treatment on woven sacks roll to roll online flexo printing machine for speed upto 100 meter/minute


Plastic is a man-made synthetic material, which contains long homogeneous molecular chains that form a strong and uniform product. The chains of molecules are normally joined end to end forming even longer chains, leaving only a few open chain ends, thus providing only a small amount of bonding points at the surface. The small amount of bonding points cause the low adhesion and wettability, which is a problem in converting processes. When the Danish engineer and founder of Vetaphone, Verner Eisby, was asked about a solution to this problem, he came up with a theory that that a high frequency charge would provide both a more efficient end controllable method of increasing the adhesion and wettability of a plastic surface.

During corona discharge treatment, electrons are accelerated into the surface of the plastic causing the long chains to rupture, producing a multiplicity of open ends and free valences are formed.

The ozone from the electrical discharge creates an oxygenation, which in turn forms new carbonyl groups with a higher surface energy. The result is an improvement of the chemical connection (dyn/cm) between the molecules in the plastic and the applied media/liquid. This surface treatment will not reduce or change the strength. Neither will it change the appearance of the material. The Corona only changes the top molecule chains, which is 0.00001 micron thick.

E Chip Control Systems is the leader manufacturer in Corona Treatment system in Chennai and all over India.

We have solution for almost all types of corona treatment application Like
