Plasma with its unique technology has been playing a more and more important role during the fabrication of products in electronic appliances, architecture, digital devices, automotive industry, sport, and fashion, … In fact, it would be difficult to identify a modern product that has not benefited from Plasma Treatment at some stage during its manufacturing process.
So what are Plasma’s unique properties that make it lead to such widespread applications?
- Ability to treat complex 3D objects and micro-channels that are hard to reach with normal methods
- Plasma is a cleaning process without any chemicals, it’s a completely environmentally friendly process
- Easily Increase Surface Energy just in one step
- Ability to treat temperature sensitive materials
- Treat conductors, semi-conductors, and insulators which all are small and dedicate and difficult to bond
- Cost-saving with very low unit cost per treatment
- Ability to produce high value-added property to product
4 MAIN ADVANTAGES OF PLASMA TREATMENT
1. Plasma Cleaning
- Plasma cleaning is a proven, effective, economical, and environmentally safe method for critical surface preparation.
- Plasma cleaning with oxygen plasma eliminates natural and technical oils & grease at the nano-scale and reduces contamination up to 6 fold when compared with traditional wet cleaning methods, including solvent cleaning residues themselves.
- Plasma cleaning produces a pristine surface, ready for bonding or further processing, without any harmful waste material.
2. Plasma Surface Activation
- Low energy substrates are gaining popularity in many manufacturing processes. These substrates offer benefits, such as durability, flexibility, and cost-effectiveness.
- Yet while adhesives have been adapting to challenges that low surface energy poses, these substrates also can adjust by Plasma Treatment.
- Plasmas afford an effective surface activation pre-treatment prior to printing, lacquering or bonding.
- Glass and ceramics can be plasma-activated similarly.
3. Plasma Coating
- In plasma coating, a nano-scale polymer layer is formed over the entire surface area of an object placed in the plasma.
- The coating process takes just a few minutes.
- The coating produced is typically less than 1/100th thickness of a human hair, colorless, odorless, and doesn’t affect the look or feel of the material in any way.
- It is a permanent coating too, being bound to the material surface on an atomic scale.
4. Plasma Etching
- Plasma etching is used to ‘roughen’ a surface, on a microscopic scale. The surface of the component is etched with a reactive process gas.
- Material is precisely sputtered off, converted to the gas phase, and sucked away via the vacuum system. The surface area is greatly increased, making the material easily wettable.
- The etching is used before printing, bonding, and painting and is particularly useful for processing of e.g. POM and PTFE, which cannot otherwise be printed on or bonded.
