425 Fab

425's fab history

425 Fabrication is a division of 425 Manufacturing, established by Mike and Michelle Thomason. 425 Manufacturing was originally started to support general machining in the greater Rockford area and to produce aftermarket products for drilling machinery. With the exposure received from many community building projects, 425 Manufacturing gained fabrication job after fabrication job. This caused 4FD to be created, servicing aerospace, semi-trucks, retail outlets, and automotive industries. 425 Fab has also began to increase its capabilities with additional Mig Welders, Tig Welders, and A fully mobile welding rig, ready to go at a moments notice. 

The entire Thomason family believes in giving back to the community whenever possible. Below you will see the latest of our donations (occurring on 6/7/2019). The Thomason’s love animals, and joined forces with our local pet food shelter, Kibble Korner. Kibble Korner was started to help those in need if they were unable to afford food for their pets. 425 Manufacturing and 425 Fabrication Division were able to donate a total of 2,300 pounds of dog and cat food! 

Though this promotion is over now, you can still help out at kibblekorner.com or simply check out our facebook for future promotions! 

Mike Thomason


Mike is the President of 425 Fab Division. His first introduction to machinery was playing submarine commander on the Harding lathe when he was 5 years old. At 8 years old he was making rubber band guns on the band saw and by 14 years old he was working summer vacation drilling tractor pins and turning parts on the Harding that he once had only played on. Mike has a 2-year business degree from Rock Valley College, a private pilots license and over 500 hours of flight time. Mike has designed and personally built multiple website over the years and also really enjoys cool tech like most everyone at 425 Fab. He has been known to pick up a welding torch on occasion and has personally done welding repair on parts and components for over 24 years. Mike has seriously enjoyed flash burn with the best of us. When he was 16, he was welding his first roll cage for a Road Runner at the Rockford Speedway. His older brother explained that it was o.k. to tack weld without a helmet, as long as he was just tacking. After an 8-hour Saturday of welding on the roll cage he woke up at 2 a.m. with his eyes completely swelled shut. The next 24 hours were spent with his eyes bandaged closed. Mike spends most of his time helping to run 425 Manufacturing while Tyler is the driving force behind the direction of 425 Fab division. Mike enjoys working on the marketing side of 425 Fab Division and helping to make 4FD a recognizable name and logo in the Rockford area.
