RF Welding Machines

Theory of Operations

ONEX RF may seem to be a new name in the industry of RF Sealing Plastics and Forming Catheters, yet ONEX Automation was known as a great automation company that designed and manufactured assembly processes for the medical device industry since 1991.

When we built our first RF Welding machine we new nothing about RF sealing technology and could not find any company that was willing to teach us, even the basics. Now days, things haven't changed much, maximum training you will get is how to push a few buttons and change process parameters.
We learned about how the RF technology is applied for melting bonding or forming plastic products the hard way. And today, we design and manufacture our own RF generators including the RF welding machines and dies, plus, we don't mind teaching our clients what we have learned throughout the years.

For RF Welding systems we offer 2 day or 1 day condensed training seminar. If customers are interested in learning more about our Hybrid RF Generator Technology and Auto Tuners we offer the 3rd day hands on training at ONEX RF.

RF Welding Training Seminar

  • The First day will be focused on understanding the Radio Frequency, Electromagnetic Waves and the RF Energy affect on polar molecules when heating plastic or other materials.
  • The second day is focused on RF electronics, construction of RF Sealers, RF Sealing Dies and how the optimize the RF sealing process.
  • Optional third day is more advanced and hands on class for training higher level engineers on generator construction, troubleshooting, auto-tuner construction and impedance matching using different size dies and materials.
