Plasma is created by applying energy to a gas, typically through heat or electrical discharge. This energy excites the gas particles, causing them to ionize (i.e., some electrons are stripped from atoms), resulting in a mix of positive ions, electrons, and neutral particles.
Plasma behaves differently than regular gas due to its conductive and reactive properties.
The machine sends compressed gas through a small nozzle at high speed.
An electric arc is created between the electrode and the workpiece, heating the gas and turning it into plasma.
Plasma reaches extremely high temperatures (up to 25,000°C) and becomes electrically conductive.
This allows the plasma to transfer electrical energy to the workpiece, melting it instantly.
The high-speed plasma jet blows away the molten material, creating a precise and clean cut.
Converts AC power to DC and regulates the output for stable cutting performance.
Directs the plasma stream towards the material.
Provides compressed gas to generate plasma.
Plasma processes, such as PECVD and plasma etching, enable high precision at microscopic and nanoscopic levels. This is essential in fields like semiconductor manufacturing and nanotechnology, where precise material deposition and patterning are critical for creating advanced devices and components.
Plasma technology is used in a wide range of industries. In electronics, it’s crucial for microchip production, thin-film deposition, and surface modification. In healthcare, plasma is applied in sterilization, wound healing, and biocompatible surface treatments for implants. Plasma is also valuable in materials science for improving adhesion and wear resistance, and in energy for research into nuclear fusion and advanced energy storage systems.
Plasma can work at much lower temperatures than conventional thermal techniques, which is crucial when working with heat-sensitive materials like plastics, organic compounds, or flexible electronics. This low-temperature capability reduces the risk of damage and increases energy efficiency in processing.
Many plasma processes are more eco-friendly than traditional methods. Plasma requires fewer chemicals, operates at lower temperatures, and generates less waste, making it a greener alternative. It can also be used for air and water purification, breaking down pollutants in a sustainable way.
