Manufacturing, Design, R&D, Customer Service … and Services  

QC Electronics is the only corona treating equipment manufacturer with complete in-house manufacturing and design capabilities. CNC mills, lathes, waterjet, welding, painting – everything is done in-house for complete quality control. This in-house production allows us to offer unparalleled design flexibility.  Need a custom design – we do that. Looking for a stock treater?  We have them.  Space limitation or hard to fit location? No problem. Difficult material to treat? Our lab line is available to test and treat your material.  QC Electronics can provide whatever corona treating equipment, electrodes, rolls or coatings that you need – whether it be for our equipment or another brand. Expect to receive top of the line corona and plasma treating equipment from QC, but you can also contact us as an alternative supplier of ceramic electrodes, rolls, ceramic roll coatings and more.
If you are looking for an alternative supplier of parts for your existing corona treaters, we are it.

We build the best and service the rest! 
Most companies provide parts for their equipment; we provide parts and manufacturing capabilities for your entire plant!

Service – it’s what we have built our business on.

What makes us different? What makes QC unique?

QC Electronics is a family, veteran (Semper Fi) and woman owned business located in Portage, Wisconsin. We have been designing and manufacturing corona treating equipment since 1988. When you work with us, you’re working with the owners! We take a personal interest in your satisfaction.

​QC was started in 1988 in Milwaukee, Wisconsin. After several expansions, we relocated and built our production facility here in Portage. Our plant is 16,000 square feet with the capability to expand to 40,000.
Thanks for visiting our site – we look forward to working with you!

Corona Treatment Equipment for Webs, Sheets, Labs and Custom Applications

QC Electronics manufactures a complete line of corona treatment equipment. We offer application consulting so you are sure to install a system perfectly suited for your needs.

​Our goal is to design a corona treater that you put into service and forget. You have enough to do without having to become an expert on corona treating just to run your treaters! If your application demands the most recent technology, a QC corona treater will deliver it. Guaranteed.

Water Jet Cutting, Custom Manufacturing and Fabrication

Our capabilities include consulting and engineering, design and manufacturing of corona treatment equipment, electrodes, rolls and coatings. We also provide custom manufacturing services that include waterjet cutting, CNC milling, lathe work, welding, painting, sand blasting and assembly. We are a full-service custom equipment manufacturer and fabricator.

​Years ago we realized the need for in-house equipment manufacturing control. We invested in production equipment and now design equipment that other corona treater manufacturers can’t. When you tell us you need a corona treater for a specialized, impossible, application, we say, ‘No problem!’.

Ceramic Electrodes, Rolls & Coatings for all Brands of Corona Treaters

We supply ceramic electrodes, rolls and roll coatings for any make or model treater – U.S. and foreign brands. You’ll notice the quality difference in our products – that’s why people put our electrodes, rolls and coatings in ‘their’ systems! We solve problems – contact us for a quote!
