Corona treatment of syringes

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.

Non-contact treatment Electrodes do not touch the syringe barrel.
No inside treatment Opposed polarity electrodes enable treatment with no metal jig inside the barrel. This eliminates inside treatment which would cause the plunger to drag.
High line-speeds Keeps pace with any printing machine.
Fully integrated Both straight throughput and half circle lines available for full integration.
Different syringe sizes No need to change electrode set-up to cope with different syringe sizes.
Complete process control The HV-X power generator provides data and communicates with all PLC’s.
Cost efficient treatment No special requirements, only electricity necessary. The unit is a very cost efficient solution for improving surface wettability and adhesion.
Uniform treatment The electrode gate concept ensures uniform treatment.
Surface energy Depending on material and line-speed.
