The corona plasma torch is a system used for the processing of two- and three-dimensional polymeric surfaces. This plasma is created under atmospheric pressure by applying an alternating voltage with a frequency of several tens of thousands of kilohertz between two electrodes. This device is used for increasing the printability of three-dimensional polymeric and metallized parts.
Creating or increasing the Nanoscale surface roughness is among the features of this process. It is expected in this state that the wetting and color absorption qualities of fabric surfaces increase. Also, the presence of an active surface layer significantly improves the adhesion of coatings and Nano-layers by creating bonds at the atomic level.
The plasma torch system can be used for increasing printability, improving the absorption and stability of printing ink, labelling, and improving surface adhesion in various surfaces.

In summary, the advantages of using corona plasma are as follows:

1. Uniform and smooth activation of surfaces even in three-dimensions
2. Rapid activation of surfaces and the possibility of use for large dimensions
3. Processing of openings and complicated surfaces in three-dimensional objects
4. Changing surface characteristics without changing volumetric characteristics
5. Economy and durability of adhesion characteristics
6. Environmental friendliness

The system uses the dielectric barrier method, which is a form of gas discharge by placing the barrier in the discharge region and produces cold plasma. Adjusting the frequency and range of applied fields to electrodes to achieve a fully uniform, as well as the ability to adjust the processing time are some of its features. The DBD plasma system is capable of working in atmospheric pressure as well as the ability to work under pressure from the atmosphere (vacuum mode), which in many processes can produce more favorable and controllable results.
These characteristics make this type of plasma a highly effective and useful tool in the fields of medicine, biotechnology, printing and packaging industries, agriculture, chemistry, polymers, and so on. The dielectric barrier plasma can be produced in the high voltage range by using two electrodes, one of which is coated with a dielectric layer, and the distance between the two electrodes is several millimeters. The existence of a dielectric barrier limits flow and lowers the plasma temperature.

This equipment is used to create carious characteristics in fabrics and two-dimensional and three-dimensional objects.
It is possible to adjust the different operational parameters in manual and automatic modes and control the system performance via the display and control panel. Parameters such as working pressure, amount of injected gas and monomer, and different timings can be adjusted and monitored in both modes.
Special applications of this device include creating certain characteristics such as hydrophilicity, hydrophobicity, stain-proof and grease-proof, and slow burning characteristics in cloth, shoes, garments, electronic boards, and various polymeric and composite substrates.

The RF switch is used for connecting one source to several consumers. One special application of these high-power RF switches as a radiofrequency generator output switch among several electrodes or sputtering guns.

The MWJ30BF Microwave Plasma Jet System is a set that is able to ionize many types of gases passing through the glass tube located in the center of the jet, by applying the microwave frequency power. This system is capable of sustaining the plasma in various conditions and in a fully controlled condition. Special features of this system include: high ion density production, closed-loop power controlling, portable torch, Equipped with mass flow controller.

Nowadays, high-voltage power supplies required in a wide array of equipment and applications. Switching power supplies are usually preferable due to their lower weight and higher efficiency. The Basafan high-voltage power supplies are offered in the 1000-120000 V range. An important feature of the power supplies made by Basafan, especially for voltages above 20 kV, is their smaller size and weight compared to the models in the market. For example, in the 40 kV, 1000 W model fully equipped and with a separable output probe, the dimensions of the power supply are 18 × 22 × 50 cm (length × width × height), and its weight is about 10 kg.
High stability, remote control capability, high-voltage separating probe and connector, controllable output current, arc management and various types of protection, voltage and current display, and a user interface panel have all turned these high-voltage power supplies into reliable industrial products.
