Lectro-Treat Plasma TorchPlasma Torch

The Plasma Torch uses a plasma gas induced discharge for treatment of conductive or non conductive parts. The size and shape of the discharge can also be altered depending on the application of this low pressure plasma system. In addition to the treatment any pollutants will be cleaned from the surface. The size of the Plasma Torch makes it easy to incorporate into any production line.

The Plasma Torch system is different from the current low pressure systems. WIth such a system, the treatment cycle consists of a vacuum, the injection of a gas, the generation of an electrial field of variable duration, then re-pressurised state and the gas exhaustion followed by the extration treated of the parts.

The Plasma Torch operates at atmospheric pressure:
Inside a chamber a plasma is generated through a high voltage discharge. Through the electrical discharge a clean air flow, or a mixture of air with specific gases is injected.
The flow of the air through the electrical discharge causes the separation of the majority of the plasma geneous radicals. The radicals react over the surface under treatment through a nozzle similar to a torch

Utilization
The opening of the nozzle retains certain elements of the plasma and also it determines the shape of the plasmageneous discharge. Therefore this system allows the treatment non conductive plastic parts as well as conductive plastic parts, such as carbon loaded materials. In addition, it is possible to treat metallic parts.

The temperature of the discharge, contratry to other Corona systems or Plasma, is relatively high in its centre. This condition, in addition to the treatment of the surfaces, also cleans polluted surfaces, or the surfaces covered with grease or silicone.

Applications

  • Sealed beams for the automobile
  • Sealing of lids, or protection strips for the food industry.
  • Treatment and cleaning of metallic surfaces before gluing, etc.

Considering the different surface treatment systems available, the Plasma Torch is somewhat related to flaming, because of the physical and chemical reaction, which often treats at more than 72 mN/m.

Compared to the other low pressure plasma systems the plasma torch reacts with the same characteristics and may be easily integrated in the production lines.
