Springs are mechanical devices typically made of resilient materials like metal or plastic that can store and release mechanical energy. They play a crucial role in various applications and industries, providing elasticity and returning to their original shape after deforming or compressing.

With a history dating back to 1969, Draco Spring Mfg. has become one of the largest custom spring manufacturers globally. We also offer diverse services to various markets, including wire forming and metal stamping.


In its early years, Draco Spring focused on producing valve and actuator springs, meeting the stringent tolerances required by the US Navy and nuclear equipment standards. This commitment to precision laid the foundation for Draco’s reputation as a reliable and high-quality spring manufacturer.

As the years progressed, the company experienced steady growth and diversification. Draco’s ability to consistently deliver exceptional products led to its expansion into various markets, including aerospace, oil and gas, stock cars, and more. Our dedication to meeting the evolving needs of our customers propelled us to become the biggest name in spring manufacturing today.


Draco Spring’s impressive facility in Houston, TX, comprises 13 buildings spanning 110,000 square feet. This expansive physical footprint allows us to house the advanced machinery and equipment required for the intricate processes involved in custom spring manufacturing. We are conveniently located just minutes from Houston’s Hobby Airport, ensuring efficient logistics and timely deliveries to our diverse customer base.

The facility houses approximately 150 employees, each contributing their skills and expertise to ensure the company’s smooth operation. Our dedicated workforce encompasses a range of roles, including customer service professionals, inspectors, sales personnel, and production experts.



With decades of experience, Draco Spring has solidified its position as a leading force in the design and manufacturing of custom springs. Here are the services we offer:
