About Us

Superior Joining Technologies, Inc. (SJTI) has grown and developed into a highly technical and precise welding operation serving any industry that needs that level of expertise and documentation, most notably aerospace. We work to support our customers, grow each employee and then reach out to have a positive impact on our community---especially as it pertains to supporting the manufacturing industry as a whole.

"Joining with You"

Originally, the name Superior Joining Technologies, Inc. (SJTI) was created to emphasize our core competency in Precision Welding (defined as joining, or uniting, metal parts…), focusing on our commitment to high quality machinery, close tolerance tooling and fixtures and an adherence to industry standards by gifted and disciplined craftsmen.

Throughout the past twenty-five years, we have built relationships and earned the trust of our customers by joining with them in solving design issues, developing new products and forming flexible manufacturing networks to provide complete solutions. By joining multiple processes within our 55,000 sq. ft. facility, we have reduced lead-time to our customers and have greater control of cost fluctuations. Through the power of partnerships, we have joined with various providers of high quality processes and products successfully raising the level of quality compliance and reducing costs.

We have an expressed desire to see our employees succeed. Our organization has joined with them to encourage continuous education by offering tuition reimbursement which has enhanced both professional and life skills. We also offer eight hours of paid community service on an annual basis to all full-time employees.

With a passion for the education of our communities’ youth, we are continually joining with schools, service organizations and trade associations in and around our area to contribute to their goals of enriching the life experience of students and providing exposure to the rewarding world of manufacturing.

We actively participate in and join with these groups and activities:

  • First Lego League (FLL) Elementary and middle school students design, build, test and program robots using LEGO MINDSTORMS® technology
  • US FIRST Robotics (FRC 2039) team for Rockford, IL area high school students combines the excitement of sport with the rigors of science and technology
  • Stateline Quiz Bowl sponsor
  • Manufacturing Day tours and programs
  • NIU Motor Sports team
  • EdgeFactor with Jeremy Bout sponsor and events

….and that is why we say, “at Superior Joining Technologies, We’re Joining With You!”
