CNweiken Rotating Nozzle 750W Plasma Machine
Best for automotive-related coatings and plastic parts, this rotating-nozzle model supports painting, electroplating, wax removal, and silk-screen prep on car components. It also enhances adhesion for printed plastics and tempered glass surfaces. The design aims to minimize material damage while boosting surface dyne values. Use this when rotation improves coverage on curved or complex geometries. A limitation is the rotating mechanism, which may require more maintenance in high-volume settings.
- Best for automotive production lines needing thorough coverage on curved parts.
- Better for multi-material surfaces where uniform activation is important.
- Caution: Rotating nozzle components may require regular maintenance.
CNweiken Direct Nozzle 750W Plasma Machine
Best for high-precision activation and coating prep on flat surfaces, including plastics, glass, and metal where direct, focused treatment is needed. This model is well-suited for printing prep and adhesion improvement without damaging substrates. It provides strong adhesion enhancement with minimal material risk. Limitation: direct-nozzle configuration may require careful distance control to avoid overheating delicate parts.
- Choose this if you need targeted, uniform activation on flat areas.
- Better for printing and coating prep on PP, PE, and similar substrates.
- Caution: Distance control is important to prevent surface damage on sensitive materials.
INTSUPERMAI 3D Plasma Corona Treatment — 110V
Best for 3D-shaped or curved rubber and plastic parts, this 3D corona system uses low-temperature plasma to treat PP, PE, PS, silicone rubber, and similar plastics. It offers adjustable corona output to suit varied geometries. Note that metal and glass are not compatible with this model. It helps improve adhesion and production efficiency without deforming treated parts. Limitation: not suitable for rigid metal or glass substrates.
- Best for 3D surfaces and flexible plastics needing surface activation.
- Better for silicone and coated plastics in flexible packaging or automotive interiors.
- Caution: Not designed for metal or glass processing.
CNweiken Direct Nozzle — 750W (Different Model)
Best for activation and coating prep across multiple materials with direct nozzle delivery, enabling precise treatment of cable, glass, and metal surfaces. It supports printing prep and improved adhesion in manufacturing workflows. Limitation: Similar features across CNweiken models may require careful selection based on nozzle type and target geometry.
- Choose this for a straightforward, consistent activation on flat areas.
- Better when direct plume control is needed for coating preparation.
- Caution: Review nozzle compatibility with your substrate to avoid over-treatment.
TTFDSUJUS Plasma Treater for Mobile Devices — Direct Nozzle
Best for mobile device screens and lightweight electronics where compact, direct-plasma treatment is advantageous. It supports plasma surface treatment for mobile surfaces and small components, offering straightforward operation. Limitation: the compact design may limit processing width and throughput on larger panels or bulkier parts.
- Best for small parts and on-the-go production lines.
- Better for electronics and accessory surfaces needing quick activation.
- Caution: Limited handling width may restrict high-volume usage on large panels.
Buying Guide
What should you consider when choosing a plasma surface treatment machine?
- Material compatibility: Verify which substrates (plastics, glass, rubber, metal) are supported. Some models are not suitable for metal or glass.
- Nozzle type and geometry: Rotating nozzles provide coverage on curved surfaces; direct nozzles offer focused treatment on flat areas. Choose based on your part shapes.
- Voltage and power: Ensure the unit’s electrical requirements align with your facility power supply and industrial use case.
- Processing width and throughput: Larger machines suit high-volume lines; compact units fit small parts or lab environments.
- Safety and maintenance: Consider needed safety features, ease of service, and replacement part availability.
- Integration with production: Assess how the system fits into existing conveyors, jigs, or automation workflows.
