SyrinTEC is specially designed for 360° Corona treatment of PP and PE syringe barrels. Normally the SyrinTEC is built into the printing line and positioned as the final process before the barrels enter into the printing machine.
Using the SyrinTEC enables treatment of the entire outside surface without any inside treatment, which would increase friction on the inside barrel and cause the plunger to drag when used.
The purpose of surface treatment of polymer-based materials is to increase surface wettability through electrical discharge. The low surface energy of polymer-based substrates often leads to poor adhesion of inks, glues and coatings.
To obtain optimum adhesion, it is necessary to increase the surface energy of the substrate to just above that of the material to be applied. Surface treatment with corona results in improved surface adhesion properties. SyrinTEC is specially designed for optimizing the adhesion properties of printing inks onto syringe barrels which are normally made of low surface energy polymer material such as PP, PE and others.
SyrinTEC uses highly durable ceramic electrode elements resulting in complete and uniform treatment of the syringe barrels. The SyrinTEC is available both as a standard unit in a low and high speed configuration for integration into existing printing lines customised units are available for specific printing machines.
