The Best Features
Advanced Electrode Design
The patented electrode design is a key feature of our covered roll corona treaters. The electrode design is specifically optimized for extruded substrates, providing consistent and uniform treatment even at high speeds and varying material thicknesses. The design is also durable, reliable, and flexible, allowing for easy customization and maximum versatility in production.
Touch Panel Control
The touch panel control system provides operators with a powerful and intuitive interface for controlling the treater. The system is highly responsive and accurate, allowing for precise control of the treatment process, and includes a range of advanced features that can help operators optimize production and maximize productivity.
High Speed Operation
QC Electronics’ covered roll corona treaters are designed for high-speed operation, with processing speeds of over 2000 feet per minute. This makes the treaters ideal for high-volume production environments where speed and efficiency are critical.
Flexible & Modular Design
The treater’s modular design allows it to be easily customized to meet the specific needs of different applications. The system can be configured with a variety of rollers, electrodes, and power supplies to accommodate different substrates, web widths, and processing speeds.
Robust Construction
The treater is built with high-quality materials and components that are designed to withstand the rigors of continuous operation. The treater is designed to withstand high temperatures, harsh chemicals, and other challenging conditions, ensuring consistent and reliable performance even in demanding production environments.
Easy Maintenance
The swinging electrode assembly is designed to allow operators to easily access and clean the electrodes, which are an essential component of the corona treater. The electrode assembly swings out of the way, providing full access to the rollers and substrate path. This makes it easy to clean the electrodes, remove any debris or buildup, and perform routine maintenance tasks.
Cool Operation
Unlike traditional corona treaters that generate a lot of heat during operation, our advanced technology is designed to minimize heat buildup and reduce the risk of overheating. The system’s airflow design also ensures adequate oxygen supply to the corona field resulting in higher, more even dyne levels.
Proprietary Technology
While we can’t reveal all the details, we can say that our technology involves a unique approach to corona treating that optimizes power output and improves treatment performance.
