Our Story

Scott and Michelle Arendt founded CMW, a leading machine and fabrication shop, in 1993, initially operating from a horse barn. By 1998, they upgraded to a 2,000-square-foot metal building and acquired their first CNC machine. Their commitment to growth led to a move in 2001 to a 10,000-square-foot facility in an industrial park in Fenton, Missouri. As CMW expanded, they strategically separated their machine and fabrication operations, with each housed in a dedicated 10,000-square-foot building.

The company’s rapid growth continued, and in 2014, both the machine and fabrication shops were consolidated into a state-of-the-art 45,000-square-foot facility. Today, CMW operates its machine shop around the clock, five days a week, reflecting their dedication to excellence.

Scott and Michelle's philosophy emphasizes handling every job with precision, ensuring no customer has a reason to leave. They have invested significantly in creating a professional and welcoming environment for both employees and clients. Their goal is to deliver cutting-edge technology and unparalleled respect in the industry. The CMW team, which has grown over the years, is renowned for its exceptional talent and expertise, setting CMW apart as a leader in the field.

Expanding Our Horizons

As part of our commitment to growth and innovation, Custom Machine Works has acquired three additional companies: Hastings Manufacturing, Fentech, and Liberty Blasting. These acquisitions have expanded our expertise and service offerings, enabling us to better serve a diverse range of industries and meet the evolving needs of our clients.

Our Vision for the Future

At Custom Machine Works, we believe in the philosophy that no job is too small, and our mission is to always exceed customer expectations. Scott and Michelle have built CMW with the core values of hard work, integrity, and a commitment to quality. Today, the machine shop operates 24 hours a day, five days a week, reflecting our dedication to meeting the needs of our clients.

Our goal is to continue growing and embracing the latest technology while maintaining the respect and trust we've earned in the industry. The acquisitions of Hastings Manufacturing, Fentech, and Liberty Blasting have strengthened our team and broadened our capabilities, furthering our vision to lead the industry with innovation and excellence.
